Two routes to actorhood: lexicalized potency to act and identification of the actor role

Aging related obesity and type 2 diabetes mellitus suppress neuromuscular communication and aggravate skeletal muscle dysfunction in rhesus monkeys

Age-related functional deterioration in skeletal muscle raises the risk for falls, disability, and mortality in the elderly, particularly in obese people or those with type 2 diabetes mellitus (T2D). However, the response of the skeletal muscle to transitioning from obesity to diabetes remains poorly defined, despite that obesity is classified as a stage of pre-diabetes. We screened and selected spontaneously obese and diabetic rhesus monkeys and examined altered protein expression in skeletal muscle of healthy aging (CON), obesity aging (OB), and type 2 diabetes mellitus aging (T2D) rhesus monkeys using Tandem Mass Tags (TMT)-based quantitative proteomic analysis. In total, we identified 142 differentially expressed proteins. Muscle-nerve communication proteins were firstly suppressed at obese-stage. With the disintegration of skeletal muscle, mitochondrial complex I and other energy homeostasis relate proteins were significantly disordered at T2D stage. Indicating that aging related obesity suppressed muscle-nerve communication and contribute to T2D related functional deterioration of skeletal muscles in elderly rhesus monkeys. Some alterations of muscular functional regulator are detected in both obesity and T2D samples, suggesting some T2D related skeletal muscular hypofunctions are occurring at obesity or pre-obesity stage. Muscle-nerve communication proteins and muscular function related proteins could be potential therapy target or early diagnose marker of for skeletal muscular hypofunctions in aging obesity populations.

Surprisal From Language Models Can Predict ERPs in Processing Predicate-Argument Structures Only if Enriched by an Agent Preference Principle

Language models based on artificial neural networks increasingly capture key aspects of how humans process sentences. Most notably, model-based surprisals predict event-related potentials such as N400 amplitudes during parsing. Assuming that these models represent realistic estimates of human linguistic experience, their success in modeling language processing raises the possibility that the human processing system relies on no other principles than the general architecture of language models and on sufficient linguistic input. Here, we test this hypothesis on N400 effects observed during the processing of verb-final sentences in German, Basque, and Hindi. By stacking Bayesian generalised additive models, we show that, in each language, N400 amplitudes and topographies in the region of the verb are best predicted when model-based surprisals are complemented by an Agent Preference principle that transiently interprets initial role-ambiguous noun phrases as agents, leading to reanalysis when this interpretation fails. Our findings demonstrate the need for this principle independently of usage frequencies and structural differences between languages. The principle has an unequal force, however. Compared to surprisal, its effect is weakest in German, stronger in Hindi, and still stronger in Basque. This gradient is correlated with the extent to which grammars allow unmarked NPs to be patients, a structural feature that boosts reanalysis effects. We conclude that language models gain more neurobiological plausibility by incorporating an Agent Preference. Conversely, theories of human processing profit from incorporating surprisal estimates in addition to principles like the Agent Preference, which arguably have distinct evolutionary roots.

Trajectories of cognitive flexibility through kindergarten and first grade: Implications for externalizing and internalizing behavior problems in the second grade

Developmental delays in cognitive flexibility early in elementary school can potentially increase vulnerability for subsequent externalizing and internalizing psychopathology. The first goal of the current study was to identify latent subgroups of children characterized by different developmental trajectories of cognitive flexibility throughout kindergarten and first grade using data from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 dataset. The second goal was to examine whether identified longitudinal developmental trajectories of cognitive flexibility could be associated with internalizing and externalizing behaviors in the second grade, while accounting for background child (age, gender, and Spanish-speaking) and family (family income and mother's education) covariates. The analytic sample consisted of 15,827 kindergarteners (51.20% male; 48.50% White, 13.5% Black/African American, 24.3% Hispanic/Latino, 7.60% Asian, and 6.1% other), who were approximately 5.62 years old (SD = 4.48 months) at the study's outset. Most children lived in households with medium family income of approximately $50,000-$55,000. Using a growth mixture modeling approach, our analyses identified normative (91.05%; 50.4% male) and delayed (8.95%; 59.4% male) cognitive flexibility groups and demonstrated that delayed developers have higher levels of externalizing and internalizing behaviors in the second grade, even after adjusting for background covariates. Our findings, in conjunction with research on cognitive flexibility training, suggest that caregivers may lower the risk for externalizing and internalizing behaviors in delayed developers by correcting inflexible thinking, encouraging alternative solutions, and providing emotional support when children face challenging problems.

Causal inference: relating language to event representations and events in the world

Events are not isolated but rather linked to one another in various dimensions. In language processing, various sources of information-including real-world knowledge, (representations of) current linguistic input and non-linguistic visual context-help establish causal connections between events. In this review, we discuss causal inference in relation to events and event knowledge as one aspect of world knowledge, and their representations in language comprehension. To evaluate the mechanism and time course of causal inference, we gather insights from studies on (1) implicit causality/consequentiality as a specific form of causal inference regarding the protagonists of cause/consequence events, and (2) the processing of causal relations. We highlight the importance of methodology in measuring causal inference, compare the results from different research methods, and emphasize the contribution of the visual-world paradigm to achieve a better understanding of causal inference. We recommend that further investigations of causal inference consider temporally sensitive measures and more detailed contexts.

Exploring homesickness among international students in China during border closure

It is nearly three years since the World Health Organization (WHO) declared the COVID-19 crisis as a pandemic. Since its inception, border closures have been subscribed to by many countries as an extreme policy tool to curb the rate of infection amid emerging variants. China, one of the earliest countries to implement this measure just opened its borders to international students for inbound and outbound travel with several preconditions. Homesickness, a grave discomfort because of its cognitive hallmark of destabilizing the affective states and routine activities of individuals has been underexplored in many studies on the COVID-19 impact on education. This phenomenological study is the first to explore the level of border-closure-induced homesickness among international students in an Asian context (China). International students (n = 20) sampled from five universities in China were interviewed on how the COVID-19-engineered border closures have prompted homesickness among them and their development of coping skills. The thirteen (13) themes that emerged from the study suggest that the students suffered from somatic and psychological symptoms of homesickness. The social and academic life of students were negatively affected. Participants in the study relied on frequent phone calls, entertainment, and indoor and outdoor activities such as exercise and campus excursions as coping strategies against homesickness. It is advocated that higher education leaders in China put in measures to hasten the acculturation of international students to minimize their homesickness. Further research areas such as taking a keen focus on maladaptive symptoms of homesickness are also discussed.

In the shadow of COVID-19: A randomized controlled online ACT trial promoting adolescent psychological flexibility and self-compassion

Background

Although some adolescents managed to cope well with the challenges brought on by the COVID-19 pandemic, the well-being of many was adversely affected due to school closures, distance education, restrictions on gathering with friends, and limited access to mental health services. Many adolescents reported increased anxiety and depression as well as decreased psychological wellbeing due to the pandemic. Consequently, there is a need for psychological support that exceeds the strained resources available to schools to support young people during times of crisis and societal pressure.

Objective

The present study aimed to explore the effects of an online-delivered ACT intervention to promote adolescent psychological flexibility and self-compassion and decrease psychological distress during the second wave of COVID-19 in the fall of 2020.

Methods

A total of 348 adolescents aged 15-16 were randomly divided into three equal groups: 1) the iACT student coach + virtual coach group, n = 116; 2) the iACT virtual coach group, n = 116; and 3) the control group with no intervention, n = 116). Among these adolescents, 234 participated in a pre-measurement (iACT, n = 154; control, n = 80; intent-to-treat) and completed measures of psychological flexibility, self-compassion, anxiety, and depression.

Results

An investigation of all the adolescents who participated in the pre-measurement (intent-to-treat analysis, n = 234) revealed no significant differences between the three groups with regard to psychological flexibility, self-compassion, and symptoms of anxiety and depression. However, upon combining the two intervention groups and examining the adolescents who completed at least 30% of the Youth Compass program (per-protocol analysis, n = 137), small but significant differences between the iACT intervention and control groups were found regarding the psychological flexibility subscale valued action, self-compassion, and anxiety in favor of the intervention group.

Conclusions

Active use of an ACT-based online intervention under adverse circumstances may decrease symptoms of anxiety and increase psychological flexibility skills in adolescents.

Designing pain visualisation for caregivers of people with special needs: A co-creation approach

Recognizing pain in people with communicative disabilities is challenging. A support system detecting pain signals provides caregivers with information to intervene adequately. This study aims to develop a design for a user interface visualizing pain experiences for a signalling system intended for caregivers. Caregivers receive alerts, indicating the presence or absence of pain experienced by a disabled individual. The design process included the use of value proposition, a brainstorm, a mood board with basic design elements, and multiple questionnaires and focus groups. During the multi-disciplinary design process end-users were extensively involved. The final design was deemed intuitive, clear and recognizable, and useable in daily caregiving. This article describes the creation process for a non-hedonistic visualization for this niche end-user group.

Agency of Subjects and Eye Movements in Schizophrenia Spectrum Disorders

People with schizophrenia spectrum disorders (SSD) show anomalies in language processing with respect to "who is doing what" in an action. This linguistic behavior is suggestive of an atypical representation of the formal concepts of "Agent" in the lexical representation of a verb, i.e., its thematic grid. To test this hypothesis, we administered a silent-reading task with sentences including a semantic violation of the animacy trait of the grammatical subject to 30 people with SSD and 30 healthy control participants (HCs). When the anomalous grammatical subject was the Agent of the event, a significant increase of Gaze Duration was observed in HCs, but not in SSDs. Conversely, when the anomalous subject was a Theme, SSDs displayed an increased probability of go-back movements, unlike HCs. These results are suggestive of a higher tolerability for anomalous Agents in SSD compared to the normal population. The fact that SSD participants did not show a similar tolerability for anomalous Themes rules out the issue of an attention deficit. We suggest that general communication abilities in SSD might benefit from explicit training on deep linguistic structures.

Beyond the three-chamber test: toward a multimodal and objective assessment of social behavior in rodents

MAIN: In recent years, substantial advances in social neuroscience have been realized, including the generation of numerous rodent models of autism spectrum disorder. Still, it can be argued that those methods currently being used to analyze animal social behavior create a bottleneck that significantly slows down progress in this field. Indeed, the bulk of research still relies on a small number of simple behavioral paradigms, the results of which are assessed without considering behavioral dynamics. Moreover, only few variables are examined in each paradigm, thus overlooking a significant portion of the complexity that characterizes social interaction between two conspecifics, subsequently hindering our understanding of the neural mechanisms governing different aspects of social behavior. We further demonstrate these constraints by discussing the most commonly used paradigm for assessing rodent social behavior, the three-chamber test. We also point to the fact that although emotions greatly influence human social behavior, we lack reliable means for assessing the emotional state of animals during social tasks. As such, we also discuss current evidence supporting the existence of pro-social emotions and emotional cognition in animal models. We further suggest that adequate social behavior analysis requires a novel multimodal approach that employs automated and simultaneous measurements of multiple behavioral and physiological variables at high temporal resolution in socially interacting animals. We accordingly describe several computerized systems and computational tools for acquiring and analyzing such measurements. Finally, we address several behavioral and physiological variables that can be used to assess socio-emotional states in animal models and thus elucidate intricacies of social behavior so as to attain deeper insight into the brain mechanisms that mediate such behaviors. CONCLUSIONS: In summary, we suggest that combining automated multimodal measurements with machine-learning algorithms will help define socio-emotional states and determine their dynamics during various types of social tasks, thus enabling a more thorough understanding of the complexity of social behavior.

Ramadan: the month of fasting for muslim and social cohesion-mapping the unexplored effect

For Muslims, Ramadan is a month in which the fasting ritual is observed and interpreted as an event for fostering social cohesion. Therefore, this study examined the relationship between mechanical solidarity and social cohesion mediated by generosity during Ramadan. The relationships between variables were tested through PLS-SEM using data collected from 600 respondents located separately in Yogyakarta and West Sumatra. The finding showed that mechanical solidarity and social cohesion are more significant when mediated by generosity. In practice, the dimensions of charity (alms and infaq) strengthen mechanical solidarity, i.e., collective consciousness and cooperation spirit, to influence social cohesion. Furthermore, generosity activities supported mechanical solidarity in strengthening the social cohesion among Muslims in Yogyakarta and West Sumatra, Indonesia. The elaboration on the factors accelerating social cohesion is an important issue for social and religious studies. It is useful for transforming the dimensions of Islamic rituals into social impacts and determining harmony between religious communities in the future.

Subjects are not all alike: Eye-tracking the agent preference in Spanish

Experimental research on argument structure has reported mixed results regarding the processing of unaccusative and unergative predicates. Using eye tracking in the visual world paradigm, this study seeks to fill a gap in the literature by presenting new evidence of the processing distinction between agent and theme subjects. We considered two hypotheses. First, the Unaccusative Hypothesis states that unaccusative (theme) subjects involve a more complex syntactic representation than unergative (agent) subjects. It predicts a delayed reactivation of unaccusative subjects compared to unergatives after the presentation of the verb. Second, the Agent First Hypothesis states that the first ambiguous NP of a sentence will preferably be interpreted as an agent due to an attentional preference to agents over themes. It predicts a larger reactivation of agent subjects than themes. We monitored the time course of gaze fixations of 44 native speakers across a visual display while processing sentences with unaccusative, unergative and transitive verbs. One of the pictures in the visual display was semantically related to the sentential subject. We analyzed fixation patterns in three different time frames: the verb frame, the post-verb frame, and the global post-verbal frame. Results indicated that sentential subjects across the three conditions were significantly activated when participants heard the verb; this is compatible with observing a post-verbal reactivation effect. Time course and magnitude of the gaze-fixation patterns are fully compatible with the predictions made by the Agent First Hypothesis. Thus, we report new evidence for (a) a processing distinction between unaccusative and unergative predicates in sentence comprehension, and (b) an attentional preference towards agents over themes, reflected by a larger reactivation effect in agent subjects.

Anaphoric Pronouns and the Computation of Prominence Profiles

Previous research has investigated anaphoric resolution at the anaphor. Using a self-paced reading study we show that prominence profiles, i.e. the ranking of the referential candidates for anaphoric resolution, are dynamically established as discourse unfolds. We compared four types of context sentences introducing two referents and found that the cost of the computation of the prominence profile depends on the alignment of prominence-lending features, namely 'left edge', 'agent', 'subject'. Cost occurs as referents become available. Further downstream, we contrasted two types of pronouns in German, personal pronoun vs. demonstrative pronoun. By the time the pronoun is encountered, profile computation is already complete, as indicated by the lack of interaction between context and pronoun type. An effect of pronoun reveals that resolution is driven by the form-dependent strength with which an interpretation is obtained (demonstrative pronouns being more stable than personal pronouns). The results also indicate that two prominence-lending features - subjecthood and agentivity - compete with each other.

Information About Inequality of Opportunity Increases Downward Mobility Perceptions: A Population-Wide Randomized Survey Experiment

Existing evidence which is primarily based on cross-sectional and observational data suggests that perceptions of doing worse or better than parents might be more important for various life outcomes than the conventional measures of mobility based on the objective indicators of socioeconomic position. In 2021, we commissioned a nationally representative survey in Georgia which included a population-wide randomized survey experiment. We confirmed the association between, on the one hand, perceived social mobility and, on the other hand, physical and mental health, satisfaction with life, and the perceived state of affairs in the country. More importantly, the experimental design allowed us to conclude that the perception of being downwardly mobile was causally determined by a short message shared with individuals that equality of opportunity in their country was low. Those who were given information that children’s socioeconomic position was strongly linked to their parents’ socioeconomic position were seven percentage points more likely than individuals in the control group to perceive themselves as being downwardly mobile. We extrapolate these findings to the broader context and argue that the messages about (in)equality of opportunity which individuals receive in their everyday lives might also shape their perceptions of social mobility in other countries.

Person-based prominence guides incremental interpretation: Evidence from obviation in Ojibwe

Distinctions related to person and animacy have long been known to impact both the grammar and incremental processing in a way that can be described through "prominence" scales. We put the generalizability of these scales to the test by examining the processing effects of a typologically uncommon distinction known as obviation, which is found in Ojibwe, an Indigenous language of North America. Obviation contrasts the single most discourse-salient animate third person (proximate) with other non-salient third persons (obviative). Using a visual world paradigm, we show that obviation influences parsing and interpretation commitments under incremental ambiguity: Proximate nouns are assumed to be the agent of an action, while obviative nouns do not lead to strong incremental commitments. This result parallels previous findings in other languages with distinctions related to animacy and person, supporting a theory where the effect of prominence information in processing is the result of a common set of constraints derived from the alignment of scales related to person, syntactic position, and thematic role.

Family support and posttraumatic growth among tourism workers during the COVID-19 shutdown: The role of positive stress mindset

The COVID-19 pandemic has taken a severe hit on the health of workers in the tourism industry. It is crucial to understand how to help the workforce in this service industry become resilient and adaptive through this crisis. The primary objective of this research is to examine how family support nurtures tourism workers' posttraumatic growth (PTG), an adaptation form in the resilience process. The valid data were collected from 384 tourism workers who were on unpaid leave or layoff during the COVID-19 crisis. The results demonstrated the positive relationship between family support and tourism workers' PTG, for which positive stress mindset was identified as a mediation mechanism. Deliberate and intrusive ruminative thinking styles moderated the effect of family support on positive stress mindset. Theoretical and practical implications of the mechanisms through which family support promotes tourism workers' PTG are discussed.

Dimensions and mechanisms of memory organization

Memory formation is dynamic in nature, and acquisition of new information is often influenced by previous experiences. Memories sharing certain attributes are known to interact so that retrieval of one increases the likelihood of retrieving the other, raising the possibility that related memories are organized into associative mnemonic structures of interconnected representations. Although the formation and retrieval of single memories have been studied extensively, very little is known about the brain mechanisms that organize and link related memories. Here we review studies that suggest the existence of mnemonic structures in humans and animal models. These studies suggest three main dimensions of experience that can serve to organize related memories: time, space, and perceptual/conceptual similarities. We propose potential molecular, cellular, and systems mechanisms that might support organization of memories according to these dimensions.

Experimental philosophical bioethics and normative inference

This paper explores an emerging sub-field of both empirical bioethics and experimental philosophy, which has been called "experimental philosophical bioethics" (bioxphi). As an empirical discipline, bioxphi adopts the methods of experimental moral psychology and cognitive science; it does so to make sense of the eliciting factors and underlying cognitive processes that shape people's moral judgments, particularly about real-world matters of bioethical concern. Yet, as a normative discipline situated within the broader field of bioethics, it also aims to contribute to substantive ethical questions about what should be done in a given context. What are some of the ways in which this aim has been pursued? In this paper, we employ a case study approach to examine and critically evaluate four strategies from the recent literature by which scholars in bioxphi have leveraged empirical data in the service of normative arguments.

Accessibility and Historical Change: An Emergent Cluster Led Uncles and Aunts to Become Aunts and Uncles

There are times when a curiously odd relic of language presents us with a thread, which when pulled, reveals deep and general facts about human language. This paper unspools such a case. Prior to 1930, English speakers uniformly preferred male-before-female word order in conjoined nouns such as uncles and aunts; nephews and nieces; men and women. Since then, at least a half dozen items have systematically reversed their preferred order (e.g., aunts and uncles, nieces and nephews) while others have not (men and women). We review evidence that the unusual reversals began with mother and dad(dy) and spread to semantically and morphologically related binomials over a period of decades. The present work proposes that three aspects of cognitive accessibility combine to quantify the probability of A&B order: (1) the relative accessibility of the A&B terms individually, (2) competition from B&A order, and critically, (3) cluster strength (i.e., similarity to related A'&B' cases). The emergent cluster of female-first binomials highlights the influence of semantic neighborhoods in memory retrieval. We suggest that cognitive accessibility can be used to predict the word order of both familiar and novel binomials generally, as well as the diachronic change focused on here.

Salience-weighted agreement feature hierarchy modulates language comprehension

The brain establishes relations between elements of an unfolding sentence in order to incrementally build a representation of who is doing what based on various linguistic cues. Many languages systematically mark the verb and/or its arguments to imply the manner in which they are related. A common mechanism to this end is subject-verb agreement, whereby the marking on the verb covaries with one or more of the features such as person, number and gender of the subject argument in a sentence. The cross-linguistic variability of these features would suggest that they may modulate language comprehension differentially based on their relative weightings in a given language. To test this, we investigated the processing of subject-verb agreement in simple intransitive Arabic sentences in a visual event-related brain potential (ERP) study. Specifically, we examined the differences, if any, that ensue in the processing of person, number and gender features during online comprehension, employing sentences in which the verb either showed full agreement with the subject noun (singular or plural) or did not agree in one of the features. ERP responses were measured at the post-nominal verb. Results showed a biphasic negativity-late-positivity effect when the verb did not agree with its subject noun in either of the features, in line with similar findings from other languages. Crucially however, the biphasic effect for agreement violations was systematically graded based on the feature that was violated, which is a novel finding in view of results from other languages. Furthermore, this graded effect was qualitatively different for singular and plural subjects based on the differing salience of the features for each subject-type. These results suggest that agreement features, varying in their salience due to their language-specific weightings, differentially modulate language comprehension. We postulate a Salience-weighted Feature Hierarchy based on our findings and argue that this parsimoniously accounts for the diversity of existing cross-linguistic neurophysiological results on verb agreement processing.

Cognitive Enhancement: Unanswered Questions About Human Psychology and Social Behavior

Stimulant drugs, transcranial magnetic stimulation, brain-computer interfaces, and even genetic modifications are all discussed as forms of potential cognitive enhancement. Cognitive enhancement can be conceived as a benefit-seeking strategy used by healthy individuals to enhance cognitive abilities such as learning, memory, attention, or vigilance. This phenomenon is hotly debated in the public, professional, and scientific literature. Many of the statements favoring cognitive enhancement (e.g., related to greater productivity and autonomy) or opposing it (e.g., related to health-risks and social expectations) rely on claims about human welfare and human flourishing. But with real-world evidence from the social and psychological sciences often missing to support (or invalidate) these claims, the debate about cognitive enhancement is stalled. In this paper, we describe a set of crucial debated questions about psychological and social aspects of cognitive enhancement (e.g., intrinsic motivation, well-being) and explain why they are of fundamental importance to address in the cognitive enhancement debate and in future research. We propose studies targeting social and psychological outcomes associated with cognitive enhancers (e.g., stigmatization, burnout, mental well-being, work motivation). We also voice a call for scientific evidence, inclusive of but not limited to biological health outcomes, to thoroughly assess the impact of enhancement. This evidence is needed to engage in empirically informed policymaking, as well as to promote the mental and physical health of users and non-users of enhancement.

Longing and Fear: The Ambivalence About Having a Relationship in Psychotherapy

It is unquestioned that reaching the hypnotic state is helped along by relational factors and that, conversely, relational experiences can be deepened through hypnosis. It is also true that deepening the experience of being in a relationship with another person is neither comfortable nor indicated for every patient or therapist. Most humans feel ambivalent about closeness. People vary in their desire for and their skill in sustaining mature intimacy. When we move along the continuum from rudimentary notions about relational factors in psychotherapy, such as rapport, to complex concepts, such as enactments, we move along a corresponding continuum of increasing need for specialized training, supervised experience, and personal therapy. The field of psychotherapy has been plagued from its inception by not knowing what to do with the tensions that emerge when two people listen to and look at each other. Avoiding relational factors may be a very human response to a very daunting matter.

The Value of Character-Based Judgement in the Professional Domain

Dimensions of character are often overlooked in professional practice at the expense of the development of technical competence and operational efficiency. Drawing on philosophical accounts of virtue ethics and positive psychology, the present work attempts to elevate the role of 'good' character in the professional domain. A 'good' professional is ideally one that exemplifies dimensions of character informed by sound judgement. A total of 2340 professionals, from five discrete professions, were profiled based on their valuation of qualities pertaining to character and judgement. Profile differences were subsequently examined in the self-reported experience of professional purpose towards a wider societal 'good'. Analysis of covariance, controlling for stage of career, revealed that professionals valuing character reported higher professional purpose than those overweighting the importance of judgement or valuing neither character nor judgement, F(3, 2054) = 7.92, p < .001. No differences were found between the two groups valuing character, irrespective of whether judgement was valued simultaneously. This profiling analysis of entry-level and in-service professionals, based on their holistic character composition, paves the way for fresh philosophical discussion regarding what constitutes a 'good' professional and the interplay between character and judgement. The empirical findings may be of substantive value in helping to recognise how the dimensions of character and judgement may impact upon practitioners' professional purpose.

Toward a Neurobiologically Plausible Model of Language-Related, Negative Event-Related Potentials

Language-related event-related potential (ERP) components such as the N400 have traditionally been associated with linguistic or cognitive functional interpretations. By contrast, it has been considerably more difficult to relate these components to neurobiologically grounded accounts of language. Here, we propose a theoretical framework based on a predictive coding architecture, within which negative language-related ERP components such as the N400 can be accounted for in a neurobiologically plausible manner. Specifically, we posit that the amplitude of negative language-related ERP components reflects precision-weighted prediction error signals, i.e., prediction errors weighted by the relevance of the information source leading to the error. From this perspective, precision has a direct link to cue validity in a particular language and, thereby, to relevance of individual linguistic features for internal model updating. We view components such as the N400 and LAN as members of a family with similar functional characteristics and suggest that latency and topography differences between these components reflect the locus of prediction errors and model updating within a hierarchically organized cortical predictive coding architecture. This account has the potential to unify findings from the full range of the N400 literature, including word-level, sentence-, and discourse-level results as well as cross-linguistic differences.

Ways of coping with excessive academic stress among Korean adolescents during leisure time

PURPOSE

Korean adolescents are under excessive academic pressure because of the competitive college entrance examination. This study examined the characteristics of coping strategies on the academic stress experienced by senior high school students in Korea.

METHODS

A total of 11 adolescents who were preparing for the college entrance examination participated in this study. This study employed semi-structured in-depth interviews. A constructive grounded theory was employed to capture the characteristics of stress-coping strategies among adolescents.

RESULTS

After analyzing the data, we identified four themes as strategic attributes of stress-coping for academic stress among Korean adolescents: (a) creating coping strategies in a physically active manner; (b) creating coping strategies in a non-physical and positive form; (c) utilizing maladaptive coping mechanisms; and (d) relying upon religious belief and spiritual power.

CONCLUSION

This study indicates that Korean adolescents developed their own coping strategies to deal with various academic stressors through either positive or negative forms of leisure.

Using Virtual Reality to Create an Observational Assessment of Adolescent Resistance to Antisocial Peer Pressure

Resistance to antisocial peer pressure consistently relates to adolescent adjustment. However, it is typically measured via a mono-method, self-report approach. The current study introduces a virtual reality (VR) protocol to create an observational measure of adolescents' responses to peer pressure to engage in antisocial activities. Data on the reliability and validity of the assessment procedure are presented. Participants (N = 264, 46% male, M_age = 18.17 years, 81% White) provided self-reports of susceptibility to antisocial peer pressure, antisocial behavior, dating violence perpetration, and depressive symptoms. Participants also engaged in 9 VR simulations, 4 of which involved antisocial peer pressure. Participant behavior in the VR simulations was coded for resistance to antisocial peer pressure. Approximately half the sample repeated the VR simulations at a 2-month follow-up. Resistance to antisocial peer pressure in 4 VR simulations evidenced item/simulation-level convergent validity with one another and discriminant validity against scores in 5 VR bystander behavior simulations. When scores from the 4 antisocial peer pressure VR simulations were summed into a total scale score, they demonstrated acceptable internal consistency, 2-month test-retest correlations, convergent validity with self-reports of susceptibility to antisocial peer pressure, and criterion validity with self-reports of antisocial behavior and dating violence perpetration. Associations with antisocial behavior and dating violence perpetration held after accounting for self-reports of susceptibility to antisocial peer pressure and participant gender. Results provide evidence that VR simulations may offer a psychometrically sound addition to self-report measures as a method for assessing responses to antisocial peer pressure.

Affective Responses to Gay Men Using Facial Electromyography: Is There a Psychophysiological "Look" of Anti-Gay Bias

Despite a wealth of attitudinal studies that elucidate the psychological correlates of anti-gay bias, studies that provide evidence of the physiological correlates of anti-gay bias remain relatively scarce. The present study addresses the under-representation of physiological research in the area of homonegativity by examining psychophysiological markers, namely the affective manifestations of anti-gay prejudice, and their correspondence with anti-gay behavior. Facial electromyography (EMG) was the technique used to acquire the psychophysiological markers via recordings from two facial muscle sites. Whether heterosexual men's implicit affective reactions to gay male couples best predicted their overt and covert discriminatory behavior toward a presumed gay male confederate was determined. The strength of the implicit affective reactions to predict anti-gay discrimination was then tested against the strength of participants' implicit cognitive reactions acquired via the Implicit Association Test (IAT). Results indicated that the affective reactions recorded via facial EMG emerged as the strongest predictor of discrimination toward gay men compared to the cognitive reactions recorded using the IAT. Findings support the contention that emotional reactions to gay men using implicit techniques such as facial EMG are potentially valuable pathways toward understanding the nature and sequelae of anti-gay behavior.

Sentence-Level Effects of Literary Genre: Behavioral and Electrophysiological Evidence

The current study used event-related brain potentials (ERPs) and behavioral measures to examine effects of genre awareness on sentence processing and evaluation. We hypothesized that genre awareness modulates effects of genre-typical manipulations. We manipulated instructions between participants, either specifying a genre (poetry) or not (neutral). Sentences contained genre-typical variations of semantic congruency (congruent/incongruent) and morpho-phonological features (archaic/contemporary inflections). Offline ratings of meaningfulness (n = 64/group) showed higher average ratings for semantically incongruent sentences in the poetry vs. neutral condition. ERPs during sentence reading (n = 24/group; RSVP presentation at a fixed per-constituent rate; probe task) showed a left-lateralized N400-like effect for contemporary vs. archaic inflections. Semantic congruency elicited a bilateral posterior N400 effect for incongruent vs. congruent continuations followed by a centro-parietal positivity (P600). While N400 amplitudes were insensitive to the genre, the latency of the P600 was delayed by the poetry instruction. From these results, we conclude that during real-time sentence comprehension, readers are sensitive to subtle morphological manipulations and the implicit prosodic differences that accompany them. By contrast, genre awareness affects later stages of comprehension.

Electrophysiology Reveals the Neural Dynamics of Naturalistic Auditory Language Processing: Event-Related Potentials Reflect Continuous Model Updates

The recent trend away from ANOVA-based analyses places experimental investigations into the neurobiology of cognition in more naturalistic and ecologically valid designs within reach. Using mixed-effects models for epoch-based regression, we demonstrate the feasibility of examining event-related potentials (ERPs), and in particular the N400, to study the neural dynamics of human auditory language processing in a naturalistic setting. Despite the large variability between trials during naturalistic stimulation, we replicated previous findings from the literature: the effects of frequency, animacy, and word order and find previously unexplored interaction effects. This suggests a new perspective on ERPs, namely, as a continuous modulation reflecting continuous stimulation instead of a series of discrete and essentially sequential processes locked to discrete events.

Violating instructed human agency: An fMRI study on ocular tracking of biological and nonbiological motion stimuli

Previous studies have shown that beliefs about the human origin of a stimulus are capable of modulating the coupling of perception and action. Such beliefs can be based on top-down recognition of the identity of an actor or bottom-up observation of the behavior of the stimulus. Instructed human agency has been shown to lead to superior tracking performance of a moving dot as compared to instructed computer agency, especially when the dot followed a biological velocity profile and thus matched the predicted movement, whereas a violation of instructed human agency by a nonbiological dot motion impaired oculomotor tracking (Zwickel et al., 2012). This suggests that the instructed agency biases the selection of predictive models on the movement trajectory of the dot motion. The aim of the present fMRI study was to examine the neural correlates of top-down and bottom-up modulations of perception-action couplings by manipulating the instructed agency (human action vs. computer-generated action) and the observable behavior of the stimulus (biological vs. nonbiological velocity profile). To this end, participants performed an oculomotor tracking task in an MRI environment. Oculomotor tracking activated areas of the eye movement network. A right-hemisphere occipito-temporal cluster comprising the motion-sensitive area V5 showed a preference for the biological as compared to the nonbiological velocity profile. Importantly, a mismatch between instructed human agency and a nonbiological velocity profile primarily activated medial-frontal areas comprising the frontal pole, the paracingulate gyrus, and the anterior cingulate gyrus, as well as the cerebellum and the supplementary eye field as part of the eye movement network. This mismatch effect was specific to the instructed human agency and did not occur in conditions with a mismatch between instructed computer agency and a biological velocity profile. Our results support the hypothesis that humans activate a specific predictive model for biological movements based on their own motor expertise. A violation of this predictive model causes costs as the movement needs to be corrected in accordance with incoming (nonbiological) sensory information.

Examining the Role of Leadership in an Undergraduate Biology Institutional Reform Initiative

Undergraduate science, technology, engineering, and mathematics (STEM) education reform continues to be a national priority. We studied a reform process in undergraduate biology at a research-intensive university to explore what leadership issues arose in implementation of the initiative when characterized with a descriptive case study method. The data were drawn from transcripts of meetings that occurred over the first 2 years of the reform process. Two literature-based models of change were used as lenses through which to view the data. We find that easing the burden of an undergraduate education reform initiative on faculty through articulating clear outcomes, developing shared vision across stakeholders on how to achieve those outcomes, providing appropriate reward systems, and ensuring faculty have ample opportunity to influence the initiative all appear to increase the success of reform. The two literature-based models were assessed, and an extended model of change is presented that moves from change in STEM instructional strategies to STEM organizational change strategies. These lessons may be transferable to other institutions engaging in education reform.
