Abstract
This review article was awarded the Dirk Hellhammer award from ISPNE in 2023. It explores the dynamic relationship between stressors and stress from a historical view as well as a vision towards the future of stress research via virtual reality (VR). We introduce the concept of a "syncytium," a permeable boundary that blurs the distinction between stress and stressor, in order to understand why the field of stress biology continues to inadequately measure stress alone as a proxy for the force of external stressors. Using Virtual Reality (VR) as an illustrative example to explicate the black box of stressors, we examine the distinction between 'immersion' and 'presence' as analogous terms for stressor and stress, respectively. We argue that the conventional psychological approaches to stress measurement and appraisal theory unfortunately fall short in quantifying the force of the stressor, leading to reverse causality fallacies. Further, the concept of affordances is introduced as an ecological or holistic tool to measure and design a stressor's force, bridging the gap between the external environment and an individual's physiological response to stress. Affordances also serve to ameliorate shortcomings in stress appraisal by integrating ecological interdependencies. By combining VR and psychobiological measures, this paper aims to unravel the complexity of the stressor-stress syncytium, highlighting the necessity of assessing both the internal and external facets to gain a holistic understanding of stress physiology and shift away from reverse causality reasoning. We find that the utility of VR extends beyond presence to include affordance-based measures of immersion, which can effectively model stressor force. Future research should prioritize the development of tools that can measure both immersion and presence, thereby providing a more comprehensive understanding of how external stressors interact with individual psychological states.

Abstract
Previous studies have shown that choices about how to configure stepping-stones to be used as playground or exercise equipment reflect a person's action capabilities. In two experiments, we investigated whether choices about how to configure stepping-stones to be used as a path for locomotion additionally reflect the goals for which or the constraints under which the path is to be used. In Experiment 1, participants created stepping-stone configurations (with rubber mats) that would allow them to cross a given space quickly, comfortably, or carefully. Configurations in the "Quickly" condition consisted of fewer mats, and longer mean (linear) distances between mats, and greater "challenge" (relative to maximum stepping distance) than in the other two conditions. In Experiment 2, participants created stepping-stone configurations that would be fun to use or that would be easy to use to cross a given space. Configurations in the "Fun" condition consisted of more mats, longer linear distances between mats, and greater "challenge" than those in the "Easy" condition. Moreover, paths in the "Fun" condition were also wider, longer, and exhibited larger changes in distances and angles between consecutive mats than in the "Easy" condition. The results are discussed both in terms of implications for understanding affordances and for the design of stepping-stone paths.

Abstract
The affordances task serves as an important tool for the assessment of cognition and visuomotor functioning, and yet its test-retest reliability has not been established. In the affordances task, participants attend to a goal-directed task (e.g., classifying manipulable objects such as cups and pots) while suppressing their stimulus-driven, irrelevant reactions afforded by these objects (e.g., grasping their handles). This results in cognitive conflicts manifesting at the task level and the response level. In the current study, we assessed the reliability of the affordances task for the first time. While doing so, we referred to the "reliability paradox," according to which behavioral tasks that produce highly replicable group-level effects often yield low test-retest reliability due to the inadequacy of traditional correlation methods in capturing individual differences between participants. Alongside the simple test-retest correlations, we employed a Bayesian generative model that was recently demonstrated to result in a more precise estimation of test-retest reliability. Two hundred and ninety-five participants completed an online version of the affordances task twice, with a one-week gap. Performance on the online version replicated results obtained under in-lab administrations of the task. While the simple correlation method resulted in weak test-retest measures of the different effects, the generative model yielded a good reliability assessment. The current results support the utility of the affordances task as a reliable behavioral tool for the assessment of group-level and individual differences in cognitive and visuomotor functioning. The results further support the employment of generative modeling in the study of individual differences.

Abstract
The nature of music improvisation continues to provide an interesting showcase of the multifaceted and skilful ways we engage with and act within our environments. Improvising musicians are somehow able to generate musical material in real time that adaptively navigates musical situations. In this article I explore the broader aspects of improvised activity-such as our bodily interactions with the instrument and environment-as they relate to improvised music-making. I do so by drawing upon principles from the embodied cognitive sciences, namely ecological and dynamical systems approaches. Firstly, I introduce the concept of affordances to illustrate the bidirectional relationship between improvisor and environment. I then take a dynamical view, exploring the ways that a trumpet player coordinates their body with their instrument and engages with trumpet affordances in order to navigate musical situations. I continue this dynamical view, taking the improviser to be an adaptive system whose behaviours are self-organised responses to a set of constraints. To conclude, I situate my research within the wider 4E approach. I advocate that 'E' approaches, which take seriously the role of the body-instrument-environment relationship, provide an insightful perspective on the nature of improvisation.

Abstract
BACKGROUND Children naturally seek risk in play and adventurous play outdoors confers many benefits, including the potential to increase moderate-to-vigorous physical activity (MVPA). This study aimed to investigate the relationship between parent attitudes to risk and injury, and their elementary school-aged child's daily adventurous play and MVPA. METHODS A panel sample of 645 Australian parents/guardians completed an online survey consisting of several validated measures of risk and injury attitudes, and physical activity and play behaviour. Data were analysed via descriptive statistics, univariate and multivariable regressions using Stata 17. A series of exploratory univariate logistic regressions were conducted, followed by a series of multivariable logistic regressions fitted to test the association between parent risk and injury attitudes and (i) children's MVPA, (ii) active play and (iii) adventurous play, while adjusting for socio-demographic factors. RESULTS Most adult participants (81%) were female. The mean age of the child participants (53% male) was 8.6 years (SD = 2.4). On average, parents were positive about children's engagement with risk, however, 78% of parents had low tolerance of risk when presented with specific play scenarios, and attitudes towards injuries varied, with mothers more concerned than fathers. After adjusting for confounders, children with parents who were tolerant of risk in play were more likely to meet the MVPA guideline of ≥60 min daily (OR 2.86, CI: 1.41, 5.82, p < 0.004) and spend more time playing adventurously (OR 3.03, CI: 1.82, 5.06, p < 0.001). Positive associations for MVPA and adventurous play were observed across all models examining parent attitudes to risk and injury. Younger children engaged in more play and physical activity, however, more positive parent attitudes appeared to moderate the age-related influences. CONCLUSIONS We found a divergence between the outcomes parents desire for their children through engagement with risk and the play activities they are comfortable with in practice. Parent attitudes to risk and injury are potentially modifiable factors that may increase children's affordances for adventurous play and physical activity. Interventions that provide parents with practical approaches to address injury concerns and support children's risk-taking in play outdoors are recommended.

Abstract
Purpose: We investigated youth volleyball players' perception of affordances for different types of serves. Methods: Participants were separated into Less Experienced (n = 13, maximum of 3 years of competitive volleyball experience) and More Experienced (n = 11, minimum of 4 years of competitive volleyball experience) groups. In the Sideline Condition, participants were asked to report the narrowest gap, relative to either the left or right sideline, into which they could serve the ball. In the Short Condition, participants were asked to report the narrowest gap, relative to the net, into which they could serve the ball. Participants then attempted to serve into their reported gaps. Results: The proportion of successful serves was greater for the More Experienced group than for the Less Experienced group, but a statistically significant interaction revealed that this was true only when performing sideline serves. As expected, reported servable gaps were larger for the Short Serve condition (M = 3.66 m, SD = 0.67 m) than for the Sideline Serve condition (M = 1.93 m, SD = 0.71 m), F(1, 22) = 80.45, p < .001, partial η2 = 0.79. Conclusions: Our study extends previous work to a different sport (volleyball) and to different sport-specific actions (serving the ball). The finding that perceived minimum servable gap sizes were larger for short serves than for sideline serves is consistent with differences in the constraints operating on the two types of serves in the context of game play.

Abstract
Rhythms exist both in the embodied brain and the built environment. Becoming attuned to the rhythms of the environment, such as repetitive columns, can greatly affect perception. Here, we explore how the built environment affects human cognition and behavior through the concept of natural attunement, often resulting from the coordination of a person's sensory and motor systems with the rhythmic elements of the environment. We argue that the built environment should not be reduced to mere states, representations, and single variables but instead be considered a bundle of highly related continuous signals with which we can resonate. Resonance and entrainment are dynamic processes observed when intrinsic frequencies of the oscillatory brain are influenced by the oscillations of an external signal. This allows visual rhythmic stimulations of the environment to affect the brain and body through neural entrainment, cross-frequency coupling, and phase resetting. We review how real-world architectural settings can affect neural dynamics, cognitive processes, and behavior in people, suggesting the crucial role of everyday rhythms in the brain-body-environment relationship.

Abstract
Point-light displays of walking gait carries an assortment of information about the individual and this information is often perceivable to others. Some of these bits of information are entangled, with some facilitating and others inhibiting each other. We sought to untangle the perception of basic threat emotions from sex of the walker and the perceiver, as expressed through the bistable perception of anticipated approaching or withdrawing point-light walkers. Stationary point-light walkers displaying anger or fear were shown to 164 psychology student perceivers, who were told that the walkers would be either walking towards them or walking away from them. Perceivers were asked to identify the displayed emotion for each walker stimulus. Expected walker direction showed no influence on the perception of either emotion, across either sex of the perceivers or walkers. Anger was identified better on male walkers and fear was identified better on female walkers. Female perceivers were able to identify both emotions better than male perceivers, but only when displayed by female walkers. The sex of both the perceiver and the walker interact to influence the perception of basic threat emotions displayed through point-light walking gait, with implications for the development of inter-sexual and intra-sexual group cohesion programs.

Abstract
BACKGROUND Chronic Non-Specific Low Back Pain (cNSLBP) has been identified as one of the leading global causes of disability and is characterized by symptoms without clear patho-anatomical origin. The majority of clinical trials assess cNSLBP using scales or questionnaires, reporting an influence of cognitive, emotional and behavioral factors. However, few studies have explored the effect of chronic pain in daily life tasks such as walking and avoiding obstacles, which involves perceptual-motor processes to interact with the environment. RESEARCH QUESTION Are action strategies in a horizontal aperture crossing paradigm affected by cNSLBP and which factors influence these decisions ? METHODS 15 asymptomatic adults (AA) and 15 cNSLBP participants walked along a 14 m long path, crossing through apertures ranging from 0.9 to 1.8 times their shoulder width. Their movement was measured using the Qualisys system, and pain perception was evaluated by self-administered questionnaires. RESULTS The cNSLBP participants stopped rotating their shoulders for a smaller aperture relative to their shoulder width (1.18) than the AA participants (1.33). In addition, these participants walked slower, which gave them more time to make the movement adaptations necessary to cross the aperture. No correlation was found between the variables related to pain perception and the critical point but the levels of pain were low with a small variability. SIGNIFICANCE This study shows that during a horizontal aperture crossing task requiring shoulder rotation to pass through small apertures, cNSLBP participants appear to exhibit a riskier adaptive strategy than AA participants by minimizing rotations that could induce pain. This task thus makes it possible to discriminate between cNSLBP participants and pain-free participants without measuring the level of pain. The identification number registered in the clinical trials is NCT05337995.

Abstract
The present study investigated differences in priming perceptions of target objects via affordance or semantic primes. Affordances denote possibilities for action in relation to objects (e.g., chair - sit), whereas semantic primes describe related concepts and features of objects (e.g., chair - legs). In Experiments 1A/1B the effects of affordance and semantic priming were compared via a semantic-categorization task using a normed word list of objects. In Experiments 2-4 we investigated affordance priming on object identification of pictures using a shoebox-classification task. In Experiment 1A participants were asked to respond by categorizing the presented word as concrete or abstract. Experiment 1B was similar to 1A, but with a 1000 ms response deadline. Experiment 2 presented target objects as words or photographs. Experiment 3 presented target objects as photographs degraded at three levels (clear, medium blur, extreme blur). Experiment 4 presented target objects as photographs that began degraded and slowly became clear. Experiment 1B found word priming for semantic primes, but not affordances. In contrast, Experiments 2-4 found object priming was facilitated by both affordances and semantic primes. Collectively, our results indicate that affordances facilitate object classification.

Abstract
Workplace-based interactions between residents and pharmacists, though relatively underexplored, might contribute substantially to learning. This international study sought to investigate the affordances residents use for informal learning about medications, their interactions with pharmacists and patterns of resident-pharmacist engagement, as well as residents' perceived impact of these interactions on their learning. Contextual differences between US and Dutch residency training and electronic health record (EHR) may impact informal learning about medications. We conducted a cross-sectional, online, 25-item survey study, including closed-format and open-response questions among current resident physicians (post-graduate years 1-6, from a variety of residency programs n = 803) from the University of California San Francisco, the University of Minnesota, and the University Medical Center Utrecht. Responses from 173 residents in both countries revealed that these physician trainees were afforded opportunities to engage in a wide variety of pharmacotherapy-related activities but engaged differently with social and environmental resources for support. Residents from the United States (US) utilized pharmacists and Up-To-Date, whereas Dutch residents preferentially utilized the online Dutch medication information site and EHR-embedded medication resources. US residents interacted with pharmacists significantly more frequently than Dutch residents. Pharmacists provided residents with a wide range of useful information, much of which is integrated into the medication resources in the Dutch EHR-based decision-support system. While US residents reported overwhelmingly that informal interactions with pharmacists contribute to their learning about medications, Dutch residents' responses did not confirm this. Intentionally designing residents' training to include opportunities for interactions with pharmacists could potentially positively impact residents' informal workplace learning.

Abstract
The supermarket is a promising location for stimulating healthier food choices by nudging interventions. However, nudging healthy food choices in the supermarket has shown weak effects to date. The present research introduces a new nudge based on the concept of affordances - i.e., an animated character - that invites interaction with healthy food products and examines its effectiveness and appreciation in a supermarket context. We present findings of a series of three studies. In Study 1, evaluations of the new nudge were collected, revealing that the nudge was appreciated. In Studies 2 and 3, field experiments were conducted to test the nudge's effect on vegetable purchases in a real-life supermarket. Study 3 demonstrated that vegetable purchases increased significantly (up to 17%) when the affordance nudge was placed on the vegetable shelves. Furthermore, customers appreciated the nudge and its potential for implementation. Taken together, this set of studies presents compelling findings illustrating the potential of the affordance nudge for increasing healthy choices in the supermarket.

Abstract
A fundamental characteristic of human development is acquiring and accumulating tool use knowledge through observation and sensorimotor experience. Recent studies showed that, in children and adults, different action possibilities to grasp-to-move and grasp-to-use objects generate a conflict that extinguishes neural motor resonance phenomena during visual object processing. In this study, a training protocol coupled with EEG recordings was administered in virtual reality to healthy adults to evaluate whether a similar conflict occurs between novel tool use knowledge. Participants perceived and manipulated two novel 3D tools trained beforehand with either single or double-usage. A weaker reduction of mu-band (10-13 Hz) power, accompanied by a reduced inter-trial phase coherence, was recorded during the perception of the tool associated with the double-usage. These effects started within the first 200 ms of visual object processing and were predominantly recorded over the left motor system. Furthermore, interacting with the double usage tool delayed grasp-to-reach movements. The results highlight a multifunctional interference effect, such as tool use acquisition reduces the neural motor resonance phenomenon and inhibits the activation of the motor system during subsequent object recognition. These results imply that learned tool use information guides sensorimotor processes of objects.

Abstract
Students' health profession education includes learning at the workplace through placements. For students, participating in daily work activities in interaction with supervisors, co-workers and peers is a valuable practice to learn the expertise that is needed to become a health care professional. To contribute to the understanding of HPE-students' workplace learning, the focus of this study is to identify affordances and characterise student's participation during placements. We applied a research design based on observations. Three student-physiotherapists and four student-nurses were shadowed during two of their placement days. A categorisation of affordances is provided, in terms of students' participation in activities, direct interactions and indirect interactions. Students' daily participation in placements is discussed through unique combinations and sequences of the identified affordances reflecting changing patterns over time, and differences in the degree of presence or absence of supervisors, co-workers and peers.

Abstract
5G mobile communication technology is anticipated to merge with many other sectors, spurring innovation and creating substantial ripple effects. Despite the significance of this advancement, current research provides limited knowledge of users' behavioral reactions to the affordances, values, and trust generated from 5G technology. To investigate this relationship, this study used the Stimulus-response theory and the consumption values theory. The empirical data was gathered from 373 consumers in China using a survey method. To validate the model's suggested relationships, the author utilized the partial least squares-structural equation modelling (PLS-SEM) technique. The finding designates that the affordances and purchase intention relationship was mediated by consumption values and trust. Given the significance of 5G technology and its potential, this study investigates what drives and deters consumers from obtaining 5G technology. Original findings insights on the role of affordances in developing marketing strategies and increasing consumer intentions to purchase 5G technology products.

Abstract
Gardens are places where science and art combine to create environments that often offer restorative and therapeutic experience to those who encounter them. During the Covid-19 pandemic, in the UK and elsewhere there has been a surge of interest in gardening. Public appreciation of gardens and other green spaces has grown and inequality of access to gardens and outdoor spaces has been extensively documented. Gardens are prevalent and of cultural significance in the UK, where their salutary properties have been documented for centuries. Yet people's relationships with gardens during the pandemic have been relatively underexplored in academia and were already under-researched prior to the pandemic's inception. This qualitative study investigates the relationships between people and gardens during the Covid-19 pandemic. Specifically, through thematic analysis based on in-depth interviews with 12 participants, it explores the effects that the pandemic had on people's relationships with gardens during an approximately 9-month period after the first national lockdown began in the UK. It places emphasis on health and wellbeing and garden design, using the concepts of agency and affordances as lenses through which to explore people's relationships with gardens. The results of this paper support others which have found people to be more supportive of nature-friendly garden design and to feel more connected with nature since the pandemic began.

Abstract
With this inaugural lecture as Socrates Professor on the topic of Making Humane Technologies, I aim to show that artistic practices afford embedding technologies better in society. Analyzing artworks made at RAAAF, an art collective that makes visual art and experimental architecture, I will describe three aspects of making practices that may contribute to improving the embedding of technology in society: (1) the skill of working with layers of meaning; (2) the skill of creating material playgrounds that afford free exploration of the potential of new technologies and artistic experiments; and (3) the skill of openness to the possibility of having radically different socio-material practices. I will use images of several RAAAF projects to make these skills involved in making more tangible. It is artistic skills like these that can contribute to a better societal embedding of technologies.

Abstract
While the use of telehealth was common in hepatitis C healthcare in Australia in remote and regional areas prior to the COVID-19 pandemic, it has been used more broadly to improve access to hepatitis C heathcare during the pandemic. Despite its widespread uptake, little research has explored how telehealth shapes hepatitis C healthcare. In this article, we draw on the concept of affordances (Latour, 2002) and interviews with 25 healthcare practitioners to explore the emergent possibilities for hepatitis C care that take shape through telehealth. Despite suggestions that telehealth is comparable to in-person care, healthcare practitioners' accounts suggest that telehealth significantly changes the nature of their experience of providing healthcare for hepatitis C. According to these service practitioners, while it increased access to hepatitis C healthcare during the pandemic, it also afforded narrower, less personal healthcare encounters, with a focus on simple and singular issues, and reduced opportunities for communication and rapport. These affordances also discouraged the use of interpreters and by extension the inclusion of patients from non-English speaking backgrounds. However, the data collected also suggest that telehealth has the potential to afford more informal and relaxed healthcare environments and dispositions between healthcare practitioners and patients, potentially disrupting classic practitioner-patient power dynamics. In concluding, the article considers how telehealth models of care might better afford quality hepatitis C healthcare and care beyond COVID-19 pandemic conditions.

Abstract
This paper provides the first exploration of the online distribution of fake Australian COVID-19 vaccine certificates. Drawing on a collection of 2589 posts between five distributors and their community members on the alt-tech platform Gab, this study gathers key insights into the mechanics of illicit vaccine certificate distribution. The qualitative findings in this research demonstrate the various motivations and binding ideologies that underpinned this illicit distribution (e.g. anti-vaccine and anti-surveillance motivations); the unique cybercultural aspects of this online illicit network (e.g. 'crowdsourcing' the creation of fake vaccine passes); and how the online community was used to share information on the risks of engaging in this illicit service, setting the appropriate contexts of using fake vaccine passes, and the evasion of guardians in offline settings. Implications for future research in cybercrime, illicit networks, and organised crime in digital spaces are discussed.

Abstract
Many everyday objects require "hidden" affordances to use as designed (e.g., twist open a water bottle). Previous work found a reliable developmental progression in children's learning of designed actions with adult objects such as containers and zippers-from non-designed exploratory actions, to the basics of the designed action, to successful implementation. Many objects designed for children (e.g., toys) also entail designed actions (e.g., interlocking bricks) but might not require a protracted period of discovery and implementation. We encouraged 12- to 60-month-old children (n = 91) and a comparative sample of 20 adults to play with six Duplo bricks to test whether the developmental progression identified for children's learning of adult objects with hidden affordances holds for a popular toy expressly designed for children. We also examined whether children's moment-to-moment behaviors with Duplo bricks inform on general processes involved in discovery and implementation of hidden affordances. With age, children progressed from non-designed exploratory actions, to attempts to interlock, to success, suggesting that the three-step developmental progression revealed with everyday adult objects broadly applies to learning hidden affordances regardless of object type. Detailing the process of learning (the type and timing of children's non-designed actions and attempts to interlock) revealed that the degree of lag between steps of the progression depends on the transparency of the required actions, the availability of perceptual feedback, and the difficulty of the perceptual-motor requirements. Findings provide insights into factors that help or hinder learning of hidden affordances.

Abstract
The internet is often viewed as the source of a myriad of benefits and harms. However, there are problems with using this notion of "the internet" and other high-level concepts to explain the influence of communicating via everyday networked technologies on people and society. Here, we argue that research on social influence in computer-mediated communication (CMC) requires increased precision around how and why specific features of networked technologies interact with and impact psychological processes and outcomes. By reviewing research on the affordances of networked technologies, we demonstrate how the relationship between features of "the internet" and "online behaviour" can be determined by both the affordances of the environment and the psychology of the user and community. To achieve advances in this field, we argue that psychological science must provide nuanced and precise conceptualisations, operationalisations, and measurements of "internet use" and "online behaviour". We provide a template for how future research can become more systematic by examining how and why variables associated with the individual user, networked technologies, and the online community interact and intersect. If adopted, psychological science will be able to make more meaningful predictions about online and offline outcomes associated with communicating via networked technologies.

Abstract
The praxis representation network (PRN) of the left cerebral hemisphere is typically linked to the control of functional interactions with familiar tools. Surprisingly, little is known about the PRN engagement in planning and execution of tool-directed actions motivated by non-functional but purposeful action goals. Here we used functional neuroimaging to perform both univariate and multi-voxel pattern analyses (MVPA) in 20 right-handed participants who planned and later executed, with their dominant and non-dominant hands, disparate grasps of tools for different goals, including: (1) planning simple vs. demanding functional grasps of conveniently vs. inconveniently oriented tools with an intention to immediately use them, (2) planning simple—but non-functional—grasps of inconveniently oriented tools with a goal to pass them to a different person, (3) planning reaching movements directed at such tools with an intention to move/push them with the back of the hand, and (4) pantomimed execution of the earlier planned tasks. While PRN contributed to the studied interactions with tools, the engagement of its critical nodes, and/or complementary right hemisphere processing, was differently modulated by task type. E.g., planning non-functional/structural grasp-to-pass movements of inconveniently oriented tools, regardless of the hand, invoked the left parietal and prefrontal nodes significantly more than simple, non-demanding functional grasps. MVPA corroborated decoding capabilities of critical PRN areas and some of their right hemisphere counterparts. Our findings shed new lights on how performance of disparate action goals influences the extraction of object affordances, and how or to what extent it modulates the neural activity within the parieto-frontal brain networks.

Abstract
Colour conveys specific information about the status/quality of an object; whereas its role in object recognition has been widely studied, little is known about its role in sensorimotor processes. We performed three experiments to assess whether colour influences the motor representation of graspable objects. In Experiment 1, we used a grasp compatibility task, in which participants categorized each object as natural or artifact, by performing reach-to-grasp movements. Response grasps could be compatible or incompatible with the ones normally used to manipulate the objects. Results showed faster reaction times for natural objects displayed in the correct colour compared with both opposite colour and correct colour artifact objects. In Experiment 2, to directly assess the effect of colour on object motor representation, we used an interference task in which an irrelevant object was shown while performing a pre-specified reach-to-grasp movement (i.e., verbal cues: small vs. large). Results highlighted a reversed compatibility effect when objects were shown in their correct colour, but only at the beginning of the movement (10 ms SOA). Finally, we run a third experiment using the same task as in Experiment 2. In this experiment, we compared the grasp compatibility effect driven by natural objects with the grasp compatibility effect driven by dangerous natural objects (e.g., cactus), which are objects that should not elicit a grasping program. The results of Experiment 3 confirm those of Experiment 2, highlighting also specific processes related to dangerous objects. Taken together, these results revealed that colour can be significant for the motor system, highlighting the close link between colour and shape, and also specific processes related to dangerous objects.

Abstract
Task conflict emerges when a stimulus triggers two or more competing tasks. To date, task conflict has been studied mainly using the color-word Stroop task. We hypothesized that task conflict also emerges in the affordances task between the goal-directed relevant task (e.g., classifying manipulable objects such as cups and pots), and the automatic, stimulus-driven, irrelevant task afforded by these objects (e.g., grasping their handles). Thus, we expected task conflict to manifest in both congruent and incongruent trials, separately from the well-known affordances response conflict that manifests in incongruent trials between responding with the right vs. the left hand. To this end, we aimed to identify a neutral condition for the affordances task. In Experiment 1, participants performed an affordances task that included images of manipulable objects and houses. While manipulable objects evoke automatic grasping tendencies, house images were hypothesized to serve as neutral, conflict-free stimuli. House images yielded shorter reaction time (RT) than incongruent trials, indicating that they may serve as neutral stimuli for the task. House images also yielded shorter RT than congruent trials, suggesting that task conflict manifests in congruent (as well as in incongruent) affordances trials. In Experiment 2 we manipulated cognitive control in the affordance task by creating low-control and high-control blocks. While both congruent and incongruent trials were impacted by this manipulation of cognitive control, neutral trials remained unaffected. These findings indicate that the affordances task involves conflicts at both the task level and the level of response, and can be used as a supplementary, non-linguistic measure of task conflict and the activation of task control.

Abstract
Earlier studies have revealed that changes in action capabilities due to fatigue or wearing a backpack have an effect on the perception of distance in meters or steepness in angles. Although these findings are interesting by themselves, they leave us uninformed about whether the accuracy of affordance perception is affected by fatigue. Are people still capable of accurately perceiving the maximum distance jumpable after an intense physical exercise? In the present experiment, this question is addressed. We found that after maximal exertion in a squatting task, the actual maximum jumping distance significantly decreased, but recovered quickly. Interestingly, on average, the participants accurately perceived their maximum jumping distance both before and after the squatting task. Apparently, the accuracy of the affordance perception remains intact after an intense physical exercise. The implications of this finding are discussed.

Abstract
COVID-19 has caused significant and unforeseen problems for entrepreneurs. While entrepreneurs would normally seek social support to help deal with these issues, due to social distancing, physical networks are often not available. Consequently, entrepreneurs must turn to alternative support sources, such as online communities, raising the question of how support is created in such spaces. Drawing on an affordance perspective, we investigate how entrepreneurs interact with online communities and base our qualitative analysis on conversation data (76,365 posts) from an online community of entrepreneurs on Reddit during the COVID-19 pandemic. Our findings draw out four affordances that online communities offer to entrepreneurs (resolving problems, reframing problems, reflecting on situations, refocusing thinking and efforts), resulting in a framework of entrepreneurial support creation in online communities. Thus, our study contributes to debates around (1) entrepreneurs' support during COVID-19 and (2) digital affordances in the entrepreneurship context.

Abstract
Most current decision-making research focuses on classical economic scenarios, where choice offers are prespecified and where action dynamics play no role in the decision. However, our brains evolved to deal with different choice situations: "embodied decisions". As examples of embodied decisions, consider a lion that has to decide which gazelle to chase in the savannah or a person who has to select the next stone to jump on when crossing a river. Embodied decision settings raise novel questions, such as how people select from time-varying choice options and how they track the most relevant choice attributes; but they have long remained challenging to study empirically. Here, we summarize recent progress in the study of embodied decisions in sports analytics and experimental psychology. Furthermore, we introduce a formal methodology to identify the relevant dimensions of embodied choices (present and future affordances) and to map them into the attributes of classical economic decisions (probabilities and utilities), hence aligning them. Studying embodied decisions will greatly expand our understanding of what decision-making is.

Abstract
This study investigated how skill level and task complexity influence the calibration of perception–action and particularly how close an individual acts relative to his or her maximal action capabilities. Complexity was manipulated between two (Touch, Grasp) and more than two (Removing, Moving Up) nested affordance conditions. For all conditions, we examined whether advanced climbers had greater maximal action capabilities than intermediate climbers or whether they better scaled their action (i.e., acted nearer to their maximal action capabilities) or both. Eleven intermediate and 11 advanced male climbers were first asked to estimate the maximum distance that they could reach a climbing hold. The hold was moved along a slide and fixed once requested by the participant; subsequently, the distance to the starting hold was measured. After each estimation, the participant was required to execute the climbing action. After four estimation-action trials in each of the four conditions, the maximal action capability (i.e., actual maximal reaching distance) was determined. Advanced climbers demonstrated greater actual maximal reaching distances than intermediate climbers for all conditions, but they only estimated greater maximal reaching distances for the more complex conditions, which featured more than two nested affordances. When estimated maximal reaching distances were scaled to actual maximal reaching distances, advanced climbers did not differ from intermediate climbers for any condition, and there were no differences between conditions. Our findings indicate that expertise was a function of greater action capabilities, but not due to the accuracy of calibration.

Abstract
Individual differences in prosocial behavior have been consistently observed in a variety of contexts. Here, we summarize and critically discuss recent developments in two research agendas on the dispositional basis of human prosociality: a personality approach, proposing a variety of trait concepts and corresponding measures to predict prosocial behavior in different situations; and a behavioral consistency approach, testing for consistency in prosocial behaviors and its underlying latent disposition(s) across situations. Drawing on different properties of situations (so-called situational affordances), we outline a theoretical framework that can help integrate these so far hardly connected research agendas. We also point out limitations of prior research, such as a lack of theory, and provide suggestions on how to overcome them.

Abstract
In everyday situations, and particularly in some sport and working contexts, humans face an inherently unpredictable and uncertain environment. All sorts of unpredictable and unexpected things happen but typically people are able to skillfully adapt. In this paper, we address two key questions in cognitive science. First, how is an agent able to bring its previously learned skill to bear on a novel situation? Second, how can an agent be both sensitive to the particularity of a given situation, while remaining flexibly poised for many other possibilities for action? We will argue that both the sensitivity to novel situations and the sensitivity to a multiplicity of action possibilities are enabled by the property of skilled agency that we will call metastable attunement. We characterize a skilled agent's flexible interactions with a dynamically changing environment in terms of metastable dynamics in agent-environment systems. What we find in metastability is the realization of two competing tendencies: the tendency of the agent to express their intrinsic dynamics and the tendency to search for new possibilities. Metastably attuned agents are ready to engage with a multiplicity of affordances, allowing for a balance between stability and flexibility. On the one hand, agents are able to exploit affordances they are attuned to, while at the same time being ready to flexibly explore for other affordances. Metastable attunement allows agents to smoothly transition between these possible configurations so as to adapt their behaviour to what the particular situation requires. We go on to describe the role metastability plays in learning of new skills, and in skilful behaviour more generally. Finally, drawing upon work in art, architecture and sports science, we develop a number of perspectives on how to investigate metastable attunement in real life situations.

Abstract
OBJECTIVES Adolescents are the most prominent users of social media, and their exposure to different contents, platforms, and types of use continues to develop. At the same time, sleep deprivation is on the rise, which may contribute to worsened health. Therefore, this cross-sectional study set out to examine the relationships among several social media affordances, habits of use, and sleep indicators in adolescents. METHODS Students ages 12-18 from a high school on Long Island, New York (N = 410) participated in an anonymous online survey focusing on various aspects of social media use as well as major sleep indicators (sleep displacement, presleep arousal, sleep quality, fatigue). RESULTS Snapchat was the only platform to predict a worsened sleep indicator (later bedtime) and it correlated with problematic, adverse, and nighttime use, possibly due to closer relationships among users. More viewing of posts of sports, friends, and family predicted better sleep. Additionally, nighttime social media use, problematic social media use, and adverse social media use each predicted at least one worsened sleep indicator in a hierarchical regression model. CONCLUSIONS Although some implications were positive, results provided insight into the cons of social media use. This study provides evidence that in order to understand the role of social media in the sleep-wake process, one must look at the specific affordances each platform provides and the different nighttime, problematic, and adverse habits of use that can arise. Documenting the variety of media use behaviors, however, introduces a considerable multiple testing threat to this research area.

Abstract
Universal Design (UD) aims to provide designed environments that allow users to fully participate in all kinds of activities. Especially, the design of Sport and Leisure buildings should support and encourage the participation of mobility and sensory impaired people in any physical and social activity. Yet, the variety of physical and social users' needs calls for different approaches to investigate, analyze and assess how the environment fulfills users' needs and expectations. This paper presents a new analytical model that: a) investigates how people with mobility, visual, and hearing impairments interact with specific architectural features; b) links the examined user-environment interaction with the user's personal assessment of the spatial experience. The study employs the literature review of the existing analytical models, which are based on the concept of user-environment interaction and framed around empirically deducted basic human needs. These models address the issue of user-environment fit by focusing on the identification of environmental barriers. Also, some of these models are too descriptive and cannot inform the practice in creative design processes. The proposed analytical model, which is built upon the theoretical concepts of affordances and usability, aims to develop a qualitative evaluation method for identifying environmental facilitators by linking the design of architectural characteristics with the influenced perception of users of the physical and social aspects of the built environment. The model consists of three groups of elements: (1) users' physical abilities; (2) architectural features and (3) usability criteria. The inter-relations of each element across the groups develop the narrating scenarios that can be investigated from the user's perspective. This new model does not only advance the understanding of the spatial experiences of persons with mobility and sensory impairments but also offers new insights for exploring UD solutions by identifying the architectural features that enlarge the spectrum of possible user-environment interactions.

Abstract
Although most visual aesthetic preferences are likely driven by a mix of personal, historical, and cultural factors, there are exceptions: some may be driven by adaptive mechanisms of visual processing, and so may be relatively consistent across people, contexts, and time. An especially powerful example is the "inward bias": when a framed image contains a figure (e.g., a face in profile), people prefer arrangements in which the figure faces inward. Although the inward bias has been studied in many contexts, its underlying nature remains unclear. It may be a function of an image's center (as in the "affordance-space" account, in which people prefer to center the implied functional extensions of objects), or it may be a function of the frame's borders (as in the "looking-into-the-future" account, in which people dislike perspectives on scenes that won't allow them to witness predicted future actions). Here we directly contrast these possibilities using a simple novel manipulation. Observers placed a face (in profile) in a frame to maximize the image's aesthetic appeal, and across observers we varied the frame's aspect ratio. We observed a powerful inward bias, and across frame widths observers preferred an approximately constant positive ratio of space in front versus behind the face. This suggests that the inward bias is driven primarily not by the image's center, but by the frame's borders - and it is consistent with the possibility that certain regions of empty space are prioritized because they are where future actions are predicted to occur.

Abstract
We performed three experiments to investigate whether adjectives can modulate the sensorimotor activation elicited by nouns. In Experiment 1, nouns of graspable objects were used as stimuli. Participants had to decide if each noun referred to a natural or artifact, by performing either a precision or a power reach-to-grasp movement. Response grasp could be compatible or incompatible with the grasp typically used to manipulate the objects to which the nouns referred. The results revealed faster reaction times (RTs) in compatible than in incompatible trials. In Experiment 2, the nouns were combined with adjectives expressing either disadvantageous information about object graspability (e.g., sharp) or information about object color (e.g., reddish). No difference in RTs between compatible and incompatible conditions was found when disadvantageous adjectives were used. Conversely, a compatibility effect occurred when color adjectives were combined with nouns referring to natural objects. Finally, in Experiment 3 the nouns were combined with adjectives expressing tactile or shape proprieties of the objects (e.g., long or smooth). Results revealed faster RTs in compatible than in incompatible condition for both noun categories. Taken together, our findings suggest that adjectives can shape the sensorimotor activation elicited by nouns of graspable objects, highlighting that language simulation goes beyond the single-word level.

Abstract
In cognitive science, long-term anticipation, such as when planning to do something next year, is typically seen as a form of 'higher' cognition, requiring a different account than the more basic activities that can be understood in terms of responsiveness to 'affordances,' i.e. to possibilities for action. Starting from architects that anticipate the possibility to make an architectural installation over the course of many months, in this paper we develop a process-based account of affordances that includes long-term anticipation within its scope. We present a framework in which situations and their affordances unfold, and can be thought of as continuing a history of practices into a current situational activity. In this activity affordances invite skilled participants to act further. Via these invitations one situation develops into the other; an unfolding process that sets up the conditions for its own continuation. Central to our process account of affordances is the idea that engaged individuals can be responsive to the direction of the process to which their actions contribute. Anticipation, at any temporal scale, is then part and parcel of keeping attuned to the movement of the unfolding situations to which an individual contributes. We concretize our account by returning to the example of anticipation observed in architectural practice. This account of anticipation opens the door to considering a wide array of human activities traditionally characterized as 'higher' cognition in terms of engaging with affordances.

Abstract
We have recently described a facilitation effect for the execution of a walking-related action in response to distant objects/locations in the extrapersonal space. Based on the parallelism with the well-known effect of "micro-affordance", observed during the execution of functionally appropriate hand-related actions towards manipulable objects, we have referred to this effect in terms of "macro-affordance". Here we used transcranical magnetic stimulation (TMS) to investigate whether a foot-related region located in the human dorsal precuneate cortex plays a causal role in the generation and maintenance of such behavioral effect. This question was addressed by comparing the magnitude of the facilitation effect during an incidental go/no-go task, i.e. advantage for walking-related actions to pictures framing an environment from a far vs. near distance, during three different TMS conditions. The three TMS conditions were collected in all subjects in a randomized order and included stimulation of: i. a foot-related region in the anterior precuneus, ii. a control region in the middle intraparietal sulcus (mIPS), and iii. a sham condition. Enrollment in the TMS protocol was based on analysis of individual performance during a preliminary session conducted using a sham stimulation. TMS was administered at a low frequency range before the beginning of each condition. The results showed that stimulation of the foot-related region in the anterior precuneus produced a significant reduction of the walking-related facilitation effect as compared to both stimulation of the active-control region and the non-active sham stimulation. These findings suggest that the foot-related sensory-motor system directly participates in the process of extraction of the spatial features (i.e. distance) from an environmental scene that are useful for locomotion. More in general, these findings support an automatic coding of environmental affordance or "macro-affordances" in the walking-related sensory-motor system.

Abstract
Actors utilize intrinsically scaled information about their geometric and dynamic properties when perceiving their ability to pass through openings. Research about dynamic factors of affordance perception have shown that the reliability of a given movement, or the precision of one's motor control for that movement, increase the buffer space used when interacting with the environment. While previous work has assessed motor control reliability as a person-level variable (i.e., behavior is aggregated across many trials), the current study assessed how characteristics of motor control and movement reliability within a single trial impact real-time action strategies for passing through apertures. Participants walked 5 m and then passed through apertures of various widths while their motions were tracked. For each trial, we collected walking time-series data, then calculated the magnitude and complexity of the lateral sway. Assessing two behavioral measures of the buffer, we found that trial-level metrics of motor control reliability, in addition to the person-level metrics previously studied, significantly predicted the buffer on each trial. This study supports previous claims that actors pick up real-time information about their dynamic capabilities in order to perceive and act within their environment. Further, the study recommends that future affordance research consider trial-level movement data, including nonlinear analyses that inform the pattern and structure of motor control reliability.

Abstract
We typically misestimate the dimensions of our body e.g., we perceive our fingers as shorter, and our torso as more elongated, than they actually are. It stands to reason that those metric biases may also extend to objects that we interact with, to facilitate attunement with the environment. To explore this hypothesis, we compared the metric representations of seven objects and the subjects' own hand using the Line Length Judgment task, in six experiments involving 152 healthy subjects. We evaluated the size estimation errors made for each target (hand or previously observed objects) by asking subjects to compare the vertical or horizontal dimension of a specific target against the length of a vertical or horizontal line. As expected, we showed that the hand is misperceived in its dimensions. Interestingly, we found that metric biases are also present for daily-life objects, such as a mobile phone and a coffee mug, and are not affected by familiarity with the objects. In contrast, objects that are less likely to be manipulated, either because they are potentially harmful or disgusting, were differently represented. Furthermore, the propensity to interact with an object, rated by an independent sample of subjects, best predicted the pattern of metric biases associated with that object. Taken together, these findings support the hypothesis that biases affecting the hand representation extend to objects that elicit action-oriented behavior, highlighting the importance of studying the body as integrated and active in the environment.

Abstract
INTRODUCTION Risk factors are biological or environmental characteristics increasing the likelihood of delays in child development. Meanwhile, protective factors are conditions that can minimize risks and favor the acquisition of skills. Infants with risk indicators for hearing loss (RIHL) tend to live in less stimulating environments which may lead to lower cognitive, language, and motor development. OBJECTIVE To compare the cognitive, language, and motor development of infants under the influence of risk and protective factors. METHOD A cross-sectional observational study in which 259 infants aged 8-10 months were assessed for cognitive, language, and motor development using the Bayley Scales of Infant and Toddler Development - Third Edition (BSITD-III). The groups were formed according to the presence or absence of RIHL and the quality of the resources, being: SG-AE (Study Group with Adequate Environment), SG-IE (Study Group with Inadequate Environment), CG-AE (Compared Group with Adequate Environment)) and CG-IE (Compared Group with Inadequate Environment). Affordances were assessed using the questionnaire Affordances in the Home Environment for the Motor Development - Infant Scale (AHEMD-IS). The groups were compared using the Chi-square test or the Kruskal-Wallis test, followed by Dunn's multiple comparison test. The level of significance adopted was 5%. RESULTS Infants from the CG-AE performed better than the other groups in cognition and motor skills. The CG-AE language was statistically superior to the SG-IE. SG-IE showed the highest frequency of delays in all domains. CG-IE and SG-AE showed a similar frequency of delays. Adequate environment associated with the absence of RIHL (CG-AE) leads to better cognitive, language, and motor performances. CONCLUSION Biological and environmental risk factors have a similar impact on development, but the accumulation of both tends to increase the risks of developmental delay. The absence of RIHL and quality environments worked as protective factors and favored the acquisition of skills.

Abstract
Children move their hands to explore, learn and communicate about hands-on tasks. Their hand movements seem to be "learning" ahead of speech. Children shape their hand movements in accordance with spatial and temporal task properties, such as when they feel an object or simulate its movements. Their speech does not directly correspond to these spatial and temporal task properties, however. We aimed to understand whether and how hand movements' are leading cognitive development due to their ability to correspond to spatiotemporal task properties, while speech is unable to do so. We explored whether hand movements' and speech's variability changed with a change in spatiotemporal task properties, using two variability measures: Diversity indicates adaptation, while Complexity indicates flexibility to adapt. In two experiments, we asked children (4-7 years) to predict and explain about balance scale problems, whereby we either manipulated the length of the balance scale or the mass of the weights after half of the trials. In three out of four conditions, we found a change in Complexity for both hand movements and speech between first and second half of the task. In one of these conditions, we found a relation between the differences in Complexity and Diversity of hand movements and speech. Changes in spatiotemporal task properties thus often influenced both hand movements' and speech's flexibility, but there seem to be differences in how they did so. We provided many directions for future research, to further unravel the relations between hand movements, speech, task properties, variability, and cognitive development.

Abstract
Forms of artificial intelligence (AI), such as chatbots that provide automated online counselling, promise to revolutionise alcohol and other drug treatment. Although the replacement of human counsellors remains a speculative prospect, chatbots for ‘narrow AI’ tasks (e.g., assessment and referral) are increasingly being used to augment clinical practice. Little research has addressed the possibilities for care that chatbots may generate in the future, particularly in the context of alcohol and other drug counselling. To explore these issues, we draw on the concept of technological ‘affordances’ and identify the range of possibilities for care that emerging chatbot interventions may afford and foreclose depending on the contexts in which they are implemented. Our analysis is based on qualitative data from interviews with clients (n=20) and focus group discussions with counsellors (n=8) conducted as part of a larger study of an Australian online alcohol and other drug counselling service. Both clients and counsellors expressed a concern that chatbot interventions lacked a ‘human’ element, which they valued in empathic care encounters. Most clients reported that they would share less information with a chatbot than a human counsellor, and they viewed this as constraining care. However, clients and counsellors suggested that the use of narrow AI might afford possibilities for performing discrete tasks, such as screening, triage or referral. In the context of what we refer to as ‘more-than-human’ care, our findings reveal complex views about the types of affordances that chatbots may produce and foreclose in online care encounters. We conclude by discussing implications for the potential ‘addiction futures’ and care trajectories that AI technologies offer, focussing on how they might inform alcohol and other drug policy, and the design of digital healthcare.

Abstract
Online therapy sessions and other forms of digital mental health services (DMH) have seen a sharp spike in new users since the start of the COVID-19 pandemic. Having little access to their social networks and support systems, people have had to turn to digital tools and spaces to cope with their experiences of anxiety and loss. With no clear end to the pandemic in sight, many of us are likely to remain reliant upon DMH for the foreseeable future. As such, it is important to articulate some of the specific ways in which the pandemic is affecting our self and world-relation, such that we can identify how DMH services are best able to accommodate some of the newly emerging needs of their users. In this paper I will identify a specific type of loss brought about by the COVID-19 pandemic and present it as an important concept for DMH. I refer to this loss as loss of perceptual world-familiarity. Loss of perceptual world-familiarity entails a breakdown in the ongoing effortless responsiveness to our perceptual environment that characterizes much of our everyday lives. To cash this out I will turn to insights from the phenomenological tradition. Initially, my project is descriptive. I aim to bring out how loss of perceptual world-familiarity is a distinctive form of loss that is deeply pervasive yet easily overlooked-hence the relevance of explicating it for DMH purposes. But I will also venture into the space of the normative, offering some reasons for seeing perceptual world-familiarity as a component of well-being. I conclude the paper with a discussion of how loss of perceptual world-familiarity affects the therapeutic setting now that most if not all therapeutic interactions have transitioned to online spaces and I explore the potential to augment these spaces with social interaction technologies. Throughout, my discussion aims to do justice to the reality that perceptual world-familiarity is not an evenly distributed phenomenon, that factors like disability, gender and race affect its robustness, and that this ought to be reckoned with when seeking to incorporate the phenomenon into or mitigate it through DMH services.

Abstract
Many studies report differences between animals raised in an enriched environment and those living in standard conditions. Animals reared in enriched conditions demonstrate better memory and learning abilities, increased activity, reduced level of anxiety, etc. However, there is a shortage of studies investigating the impact of environmental variability on animal behaviour, and few studies on this topic focus on animals with different initial anxiety levels. This study was conducted on laboratory rats. Prior to the experiment, the rats were kept in three types of rearing conditions: an enriched stable environment; an enriched variable environment; and in standard laboratory conditions. The environment was enriched by providing a cognitively and physically stimulating living space. The variability of the environment involved altering the arrangement of the enriching objects on a daily basis. The level of reaction to food novelty was measured with a food neophobia test. The study demonstrates that an enriched environment has a significant impact on reducing food neophobia. However, our findings suggest that the variability of the environment is not necessary and does not enhance the positive impact of enrichment on these aspects of behaviour.

Abstract
Prior work shows that the calibration of perception and action transfers between actions depending on their functional similarity: Practising (and thus calibrating perception of) one affordance will also calibrate perception for an affordance with a similar function but not for an affordance with a disparate function. We tested this hypothesis by measuring whether calibration transferred between two affordances for passing through openings: squeezing sideways through doorways without becoming stuck and fitting sideways through doorways while avoiding collision. Participants wore a backpack to alter affordances for passage and create a need for perceptual recalibration. Calibration failed to transfer between the two actions (e.g., practising squeezing through doorways calibrated perception of squeezing but not fitting). Differences between squeezing and fitting affordances that might have required different information for perception and recalibration are explored to understand why calibration did not transfer. In light of these results, we propose a revised hypothesis-calibration transfers between affordances on the basis of both functional and informational similarity.

Abstract
The Covid-19 pandemic is a rare opportunity to examine some fundamental aspects of IM and IS research and practice. There are at least three areas where the pandemic has impacted practice: information management, work practices and design of technologies. The IS discipline has appropriate methods and theories to study the design of technologies and social interactions. Concepts such as “social distancing” that has emerged in the pandemic need to be studied through philosophical premises. The IM practices that emerge after the pandemic is over, will be shaped by how well we seize the opportunity to learn from the pandemic.
In this opinion paper, I argue that the Covid-19 pandemic, as tragic and disastrous as it undoubtedly is, has also given us a rare opportunity to deeply examine the research and practice of information management in particular and information systems in general. To cope with the pandemic, we have retreated to the digital world and drastically changed the way we work. Yet these very practices can well shape the way we work in the post-pandemic world. Moreover, the pandemic is also a sharp lens through which we can study deep-rooted theoretical issues that otherwise would not have surfaced, or at least remained in the background. My call to the research community is to seize this rare opportunity.

Abstract
This hybrid of review and personal essay argues that models of visual construction are essential to extend spatial navigation models to models that link episodic memory and imagination. The starting point is the TAM-WG model, combining the Taxon Affordance Model and the World Graph model of spatial navigation. The key here is to reject approaches in which memory is restricted to unanalyzed views from familiar places, and their later recall. Instead, we will seek mechanisms for imagining truly novel scenes and episodes. We thus introduce a specific variant of schema theory and VISIONS, a cooperative computation model of visual scene understanding in which a scene is represented by an assemblage of schema instances with links to lower-level "patches" of relevant visual data. We sketch a new conceptual framework for future modeling, Visual Integration of Diverse Multi-Modal Aspects, by extending VISIONS from static scenes to episodes combining agents, actions and objects and assess its relevance to both navigation and episodic memory. We can then analyze imagination as a constructive process that combines aspects of memories of prior episodes along with other schemas and adjusts them into a coherent whole which, through expectations associated with diverse episodes and schemas, may yield the linkage of episodes that constitutes a dream or a narrative. The result is IBSEN, a conceptual model of Imagination in Brain Systems for Episodes and Navigation. The essay closes by analyzing other papers in this Special Issue to assess to what extent their results relate to the research proposed here.

Abstract
Emotional state, in particular anxiety, has been shown to constrain perceptual judgement of action capabilities. However, whether anxiety also constrains actual behaviour is unknown. The current study, therefore, aimed to determine whether state anxiety constrained firstly perceptual judgements of action capabilities and secondly actual behaviour. To do this, we asked participants to make perceptual judgements and perform action behaviours in relation to crossing ground-based apertures representing puddles. State anxiety was measured in 30 participants using the State-Trait Anxiety Inventory. The critical ratio of aperture size relative to leg length at which participants' behaviour choice would switch between a step and a spring was calculated. In a perceptual judgement task, participants judged the ratio at which they would choose to switch. In a subsequent executed action task, the ratio at which they actually switched was measured. Perceptual critical ratio could be predicted via state anxiety and age, while action critical ratio was not predicted by either. Therefore, this study has demonstrated that state anxiety and age both constrain perceptual judgement of action capabilities, as shown in previous studies. However, this does not seem to result in a change in emergent behaviour. This highlights the importance of measuring emergent behaviour rather than inferring it from perceptual judgements even when they are couched in terms of action.

Abstract
Although it is well known that women have relatively high rates of attrition from STEM occupations in the United States, there is limited empirical research on the views and experiences of female STEM degree-earners that may underlie their commitment to their chosen fields. Utilizing survey data from 229 women completing STEM degrees at two U.S. universities, the present study examines how perceptions of occupational affordances and interactions with others in the field predict their occupational STEM commitment. Additionally, the study employs an intersectional lens to consider whether the patterns of association are different for Asian women and White women. Multivariate regression analyses reveal that although communal goal affordances do not significantly predict women's occupational STEM commitment, agentic goal affordances are a strong predictor of such commitment. Regarding experiences with others in the field, results reveal that classmate interactions are not associated with STEM commitment, whereas positive faculty interactions do significantly predict such commitment. However, further analyses reveal racial differences in these patterns because agentic goal affordances are much weaker predictors of occupational STEM commitment for Asian women than for White women, and results indicate that faculty interactions are significant predictors of STEM commitment only for White women. Thus, our results strongly suggest that the theoretical models of motivation and support that underlie much of the discussion around women in STEM do not similarly apply to women from all racial backgrounds and that more research is needed that considers how both gender and race simultaneously shape STEM engagement and persistence.

Abstract
An animal's environment is rich with affordances. Different possible actions are specified by visual information while competing for dominance over neural dynamics. Affordance competition models account for this in terms of winner-takes-all cross-inhibition dynamics. Multistable phenomena also reveal how the visual system deals with ambiguity. Their key property is spontaneous instability, in forms such as alternating dominance in binocular rivalry. Theoretical models of self-inhibition or self-organized instability posit that the instability is tied to some kind of neural adaptation and that its functional significance is to enable flexible perceptual transitions. We hypothesized that the two perspectives are interlinked. Spontaneous instability is an intrinsic property of perceptual systems, but it is revealed when they are stripped from the constraints of possibilities for action. To test this, we compared a multistable gestalt phenomenon against its embodied version and estimated the neural adaptation and competition parameters of an affordance transition dynamic model. Wertheimer's (Zeitschrift fur Psychologie 61, 161-265, 1912) optimal (β) and pure (φ) forms of apparent motion from a stroboscopic point-light display were endowed with action relevance by embedding the display in a visual object-tracking task. Thus, each mode was complemented by its action, because each perceptual mode uniquely enabled different ways of tracking the target. Perceptual judgment of the traditional apparent motion exhibited spontaneous instabilities, in the form of earlier switching when the frame rate was changed stepwise. In contrast, the embodied version exhibited hysteresis, consistent with affordance transition studies. Consistent with our predictions, the parameter for competition between modes in the affordance transition model increased, and the parameter for self-inhibition vanished.
