Effects of colour-coded compartmentalised syringe trays on anaesthetic drug error detection under cognitive load

BACKGROUND

Anaesthetic drug administration is complex, and typical clinical environments can entail significant cognitive load. Colour-coded anaesthetic drug trays have shown promising results for error identification and reducing cognitive load.

METHODS

We used experimental psychology methods to test the potential benefits of colour-coded compartmentalised trays compared with conventional trays in a simulated visual search task. Effects of cognitive load were also explored through an accompanying working memory-based task. We hypothesised that colour-coded compartmentalised trays would improve drug-detection error, reduce search time, and reduce cognitive load. This comprised a cognitive load memory task presented alongside a visual search task to detect drug errors.

RESULTS

All 53 participants completed 36 trials, which were counterbalanced across the two tray types and 18 different vignettes. There were 16 error-present and 20 error-absent trials, with 18 trials presented for each preloaded tray type. Syringe errors were detected more often in the colour-coded trays than in the conventional trays (91% vs 83%, respectively; P=0.006). In signal detection analysis, colour-coded trays resulted in more sensitivity to the error signal (2.28 vs 1.50, respectively; P<0.001). Confidence in response accuracy correlated more strongly with task performance for the colour-coded tray condition, indicating improved metacognitive sensitivity to task performance (r=0.696 vs r=0.447).

CONCLUSIONS

Colour coding and compartmentalisation enhanced visual search efficacy of drug trays. This is further evidence that introducing standardised colour-coded trays into operating theatres and procedural suites would add an additional layer of safety for anaesthetic procedures.

Standardised colour-coded compartmentalised syringe trays improve anaesthetic medication visual search and mitigate cognitive load

BACKGROUND

Anaesthetic procedures are complex and subject to human error. Interventions to alleviate medication errors include organised syringe storage trays, but no standardised methods for drug storage have yet been widely implemented.

METHODS

We used experimental psychology methods to explore the potential benefits of colour-coded compartmentalised trays compared with conventional trays in a visual search task. We hypothesised that colour-coded compartmentalised trays would reduce search time and improve error detection for both behavioural and eye-movement responses. We recruited 40 volunteers to identify syringe errors presented in pre-loaded trays for 16 trials in total: 12 error present and four error absent, with eight trials presented for each tray type.

RESULTS

Errors were detected faster when presented in the colour-coded compartmentalised trays than in conventional trays (11.1 s vs 13.0 s, respectively; P=0.026). This finding was replicated for correct responses for error-absent trays (13.3 s vs 17.4 s, respectively; P=0.001) and in the verification time of error-absent trays (13.1 s vs 17.2 s, respectively; P=0.001). On error trials, eye-tracking measures revealed more fixations on the drug error for colour-coded compartmentalised trays (5.3 vs 4.3, respectively; P<0.001), whilst more fixations on the drug lists for conventional trays (8.3 vs 7.1, respectively; P=0.010). On error-absent trials, participants spent longer fixating on the conventional trials (7.2 s vs 5.6 s, respectively; P=0.002).

CONCLUSIONS

Colour-coded compartmentalisation enhanced visual search efficacy of pre-loaded trays. Reduced fixations and fixation times for the loaded tray were shown for colour-coded compartmentalised trays, indicating a reduction in cognitive load. Overall, colour-coded compartmentalised trays were associated with significant performance improvements when compared with conventional trays.

Nurturing compassion in schools: A randomized controlled trial of the effectiveness of a Compassionate Mind Training program for teachers

OBJECTIVES

Schools are experiencing an unprecedented mental health crisis, with teachers reporting high levels of stress and burnout, which has adverse consequences to their mental and physical health. Addressing mental and physical health problems and promoting wellbeing in educational settings is thus a global priority. This study investigated the feasibility and effectiveness of an 8-week Compassionate Mind Training program for Teachers (CMT-T) on indicators of psychological and physiological wellbeing.

METHODS

A pragmatic randomized controlled study with a stepped-wedge design was conducted in a sample of 155 public school teachers, who were randomized to CMT-T (n = 80) or a waitlist control group (WLC; n = 75). Participants completed self-report measures of psychological distress, burnout, overall and professional wellbeing, compassion and self-criticism at baseline, post-intervention, and 3-months follow-up. In a sub-sample (CMT-T, n = 51; WLC n = 36) resting heart-rate variability (HRV) was measured at baseline and post-intervention.

RESULTS

CMT-T was feasible and effective. Compared to the WLC, the CMT-T group showed improvements in self-compassion, compassion to others, positive affect, and HRV as well as reductions in fears of compassion, anxiety and depression. WLC participants who received CMT-T revealed additional improvements in compassion for others and from others, and satisfaction with professional life, along with decreases in burnout and stress. Teachers scoring higher in self-criticism at baseline revealed greater improvements post CMT-T. At 3-month follow-up improvements were retained.

CONCLUSIONS

CMT-T shows promise as a compassion-focused intervention for enhancing compassion, wellbeing and reducing psychophysiological distress in teachers, contributing to nurturing compassionate, prosocial and resilient educational environments. Given its favourable and sustainable effects on wellbeing and psychophysiological distress, and low cost to deliver, broader implementation and dissemination of CMT-T is encouraged.

Interpretation Biases in Pain: Validation of Two New Stimulus Sets

Adults with chronic pain interpret ambiguous information in a pain and illness related fashion. However, limitations have been highlighted with traditional experimental paradigms used to measure interpretation biases. Whilst ambiguous scenarios have been developed to measure interpretation biases in adolescents with pain, no scenario sets exist for use with adults. Therefore, the present study: (i) sought to validate a range of ambiguous scenarios suitable for measuring interpretation biases in adults, whilst also allowing for two response formats (forced-choice and free response); and (ii) investigate paradigm efficacy, by assessing the effects of recent pain experiences on task responding. A novel ambiguous scenarios task was administered to adults (N = 241). Participants were presented with 62 ambiguous scenarios comprising 42 that could be interpreted in a pain/pain-illness or non-pain/non-pain illness manner: and 20 control scenarios. Participants generated their own solutions to each scenario (Word Generation Task), then rated how likely they would be to use two researcher-generated solutions to complete each scenario (Likelihood Ratings Task). Participants also rated their subjective experiences of pain in the last 3 months. Tests of reliability, including inter-rater agreement and internal consistency, produced two ambiguous scenario stimulus sets containing 18 and 20 scenarios, respectively. Further analyses revealed adults who reported more recent pain experiences were more likely to endorse the pain/pain-illness solutions in the Likelihood Ratings Task. This study provides two new stimulus sets for use with adults (including control items) in pain research and/or interventions. Results also provide evidence for a negative endorsement bias in adults.

Influence of the COVID-19 Lockdown on the Physical and Psychosocial Well-being and Work Productivity of Remote Workers: Cross-sectional Correlational Study

BACKGROUND

Lockdowns imposed during the COVID-19 pandemic have impacted the living and working habits of millions of people, with potentially important implications for their physical, mental, and social well-being.

OBJECTIVE

The primary objective of this study was to investigate the impact of the COVID-19 pandemic on remote workers who were not directly affected by COVID-19.

METHODS

This was a correlational cross-sectional study (with an additional qualitative component) of 184 remote workers surveyed during the first COVID-19 lockdown in the United Kingdom. Standard measures of mental health (Kessler-6 Distress Scale), productivity (Brief Instrument to Assess Workers' Productivity During a Working Day), and physical activity (International Physical Activity Questionnaire) were used, and respondents were further surveyed on changes to their dietary, exercise, smoking, drinking, and socialization habits to produce a well-being change index.

RESULTS

The results revealed associations between sedentary behavior and poorer mental health (τ b=0.14) and between poorer mental health and low work productivity (τ b=-0.39). However, both positive and negative lifestyle changes were reported; a self-reported increase in well-being (with respect to diet, exercise, smoking, alcohol consumption, and socialization) since the start of the pandemic was associated with both better mental health (τ b=-0.14) and better work productivity (τ b=0.14). Of note, among respondents without a mental health diagnosis (137/184, 74.4%), we observed rates of moderate (76/137, 55.5%) and severe (17/137, 12.4%) psychological distress, which were markedly higher than those reported in large prepandemic studies; moreover, 70.1% (129/184) of our respondents reported more sedentary behavior, 41% (69/168) increased their alcohol consumption, and 38.6% (71/184) increased their overall food intake. However, 46% (75/163), 44.8% (39/87) and 51.8% (57/110) of respondents reported spending more time walking and engaging in more moderate and vigorous exercise, respectively. Qualitative analysis revealed many positive adaptations to lockdowns (eg, decreased commuting expenses, flexibility) but also a number of structural obstacles to remote working (eg, lack of support and high expectations from employers, childcare duties).

CONCLUSIONS

These findings may be of practical importance for policy makers and employers in a world in which work involves long-term remote or hybrid employment arrangements; strategies to promote more sustainable remote working are discussed.

A Systematic Review of Self-Report Measures of Negative Self-Referential Emotions Developed for Non-Clinical Child and Adolescent Samples

The crisis in child and adolescent mental health and wellbeing has prompted the development of school and community-based interventions to tackle negative emotions towards the self. Providing an evidence-base for such interventions is therefore a priority for policy makers and practitioners. This paper presents the first systematic review of self-referential and self-report measures of negative emotions for use with non-clinical child/adolescent populations, and evaluation of their psychometric properties. A systematic search of electronic databases and grey literature was conducted. Peer reviewed articles that introduced a new measure or included psychometric evaluation of a negative self-referential emotion for children and/or adolescents were identified. Study characteristics were extracted, and psychometric properties rated using internationally recognised quality criteria. Initially, 98 measures designed for evaluating children and adolescents' negative self-referential emotions were found. Measures were primarily excluded if they were intended for clinical diagnosis or did not focus on self-referential emotions. The remaining eight measures (Brief Shame and Guilt Questionnaire; Self-Consciousness Scale-Children; Shame and Guilt Scale for Adolescents; Test of Self-Conscious Affect- Adolescents; The Child-Adolescent Perfectionism Scale [CAPS]; Child and Adolescent Dysfunctional Attitudes Scale Revised; Children Automatic Thoughts Scale [CATS]; Negative Affect Self-Statement Questionnaire) were organised into domains consisting of self-conscious emotions, self-oriented perfectionism and negative self-cognitions. Psychometric quality ratings identified the CAPS (Flett et al. in J Psychoeduc Assess 34:634-652, 2016) and the CATS (Schniering and Rapee in Behav Res Ther 40:1091-1109, 2002) as having the strongest psychometric qualities. However, all reviewed measures lacked full evaluation of essential psychometric properties. Our review revealed a paucity of self-referential emotional measures suitable for assessing adverse negative self-referential emotions in general child and adolescent populations. Measures suitable for use in non-clinical samples were identified, but these require further evaluation and/or new scale developments are needed. The psychometric findings and methodological issues identified will guide researchers and practitioners to make evidence-based decisions in order to select optimal measures.

The Visual Search Strategies Underpinning Effective Observational Analysis in the Coaching of Climbing Movement

Despite the importance of effective observational analysis in coaching the technical aspects of climbing performance, limited research informs this aspect of climbing coach education. Thus, the purpose of the present research was to explore the feasibility and the utility of a novel methodology, combining eye tracking technology and cued retrospective think-aloud (RTA), to capture the cognitive–perceptual mechanisms that underpin the visual search behaviors of climbing coaches. An analysis of gaze data revealed that expert climbing coaches demonstrate fewer fixations of greater duration and fixate on distinctly different areas of the visual display than their novice counterparts. Cued RTA further demonstrated differences in the cognitive–perceptual mechanisms underpinning these visual search strategies, with expert coaches being more cognizant of their visual search strategy. To expand, the gaze behavior of expert climbing coaches was underpinned by hierarchical and complex knowledge structures relating to the principles of climbing movement. This enabled the expert coaches to actively focus on the most relevant aspects of a climber’s performance for analysis. The findings demonstrate the utility of combining eye tracking and cued RTA interviewing as a new, efficient methodology of capturing the cognitive–perceptual processes of climbing coaches to inform coaching education/strategies.

Can compassion, happiness and sympathetic concern be differentiated on the basis of facial expression?

Recent research has demonstrated the importance of positive emotions, and especially compassion, for well-being. Via two investigations, we set out to determine if facial expressions of happiness, "kind" compassion and sympathetic concern can be distinguished, given limitations of previous research. In investigation one, prototypes of the three expressions were analysed for similarities and differences using the facial action coding system (FACS) by two certified independent coders. Results established that each expression comprised distinct FACS units. Thus, in investigation 2, a new photographic stimulus set was developed using a gender/racially balanced group of actors to pose these expressions of "kind" compassion, happiness, sympathetic concern, and the face in a relaxed/neutral pose. 75 participants were then asked to name the FACS generated expressions using not only forced categorical quantitative ratings but, importantly, free response. Results revealed that kind compassionate facial expressions: (i) engendered words associated with contented and affiliative emotions (although, interestingly, not the word "kind"); (ii) were labelled as compassionate significantly more often than any of the other emotional expressions; but (iii) in common with happiness expressions, engendered happiness word groupings and ratings. Findings have implications for understandings of positive emotions, including specificity of expressions and their veridicality.

An international study of analgesic dependence among people with pain in the general population

BACKGROUND

Overuse of and dependence on analgesics (including opioids and other pain medications) are major international public health problems.

OBJECTIVE

To identify influences on analgesic dependence among analgesic users in the general populations of different countries.

METHODS

Online surveys of 1,283 people with pain in the UK, USA, Australia, Germany, Egypt and China/Macau/Hong Kong.

RESULTS

Levels of analgesic overuse and dependence were highest in Egypt and lowest in China/Macau/Hong Kong. In every country except Egypt, frequency of pain and frequency of analgesic use were correlated with analgesic dependence, and scores on the Need subscale of the Pain Medication Attitudes Questionnaire (PMAQ) independently predicted analgesic dependence. In the UK, USA, Australia, and Germany, frequency of analgesic use mediated the effects of pain frequency or intensity, and Need scores mediated the effects of frequency of analgesic use. In Egypt, more recent pain, analgesic overuse, and the Emotion and Solicitude subscales of the Survey of Pain Attitudes independently predicted analgesic dependence.

CONCLUSIONS

Across multiple countries, the impact of pain on analgesic dependence was mediated by frequency of analgesic use rather than overuse or abuse, and self-reported need for analgesics was the strongest independent predictor of dependence. Asking people directly about their feelings of needing analgesics could therefore identify those who could be helped to use analgesics less frequently, which should reduce their risk of dependence.

The physiological and emotional effects of touch: Assessing a hand-massage intervention with high self-critics

Research demonstrates that highly self-critical individuals can respond negatively to the initial introduction of a range of therapeutic interventions. Yet touch as a form of therapeutic intervention in self-critical individuals has received limited prior investigation, despite documentation of its beneficial effects for well-being. Using the Forms of Self-Criticism/Self-Reassuring Scale, 15 high- and 14 low- self-critical individuals (from a sample of 139 females) were recruited to assess how self-criticism impacts upon a single instance of focused touch. All participants took part in a hand massage- and haptic control- intervention. Salivary cortisol and alpha amylase, as well as questionnaire measures of emotional responding were taken before and after the interventions. Following hand massage, analyses revealed cortisol decreased significantly across all participants; and that significant changes in emotional responding reflected well-being improvements across all participants. Supplementary analyses further revealed decreased alpha amylase responding to hand massage as compared to a compassion-focused intervention in the same (highly self-critical) individuals. Taken together, the physiological and emotional data indicate high self-critical individuals responded in a comparable manner to low self-critical individuals to a single instance of hand massage. This highlights that focused touch may be beneficial when first engaging highly self-critical individuals with specific interventions.

Recognition of subtle and universal facial expressions in a community-based sample of adults classified with intellectual disability

BACKGROUND

Across the USA and UK, schemes now exist to aid the successful integration of adults with mild to moderate intellectual disabilities into general society. One factor that may prove important to the success of such schemes is social competence. Here, understanding the facial expressions of others is critical, as emotion recognition is a prerequisite to empathetic responding and an essential factor in social functioning. Yet research in this area is lacking, especially in community-based samples.

METHOD

We investigated the performance of 13 adults with mild to moderate intellectual disability (ID), relative to 13 age-matched controls, on three tasks of emotion recognition (emotion categorisation; recognition of valence; and recognition of arousal), using a number of 'basic' (angry and happy) and more 'subtle' (compassionate and critical) emotional expressions, as well as the posers face in a default relaxed (i.e. 'neutral') state. Importantly, the sample was drawn from a community-based initiative and was therefore representative of populations' government schemes target.

RESULTS

Across emotion recognition tasks, the ID adults, as compared with controls, were significantly impaired when labelling the emotions displayed by the poser as well as recognising the associated 'feelings' conveyed by these faces. This was especially true for the neutral, compassionate and angry facial expressions. For example, ID adults demonstrated deficits in categorising neutral and subtle emotional expressions, as well as assessing the valence of such facial expressions. In addition, ID adults also struggled to assess arousal levels; especially those associated with compassionate and angry faces.

CONCLUSION

Given both basic and subtle emotions are conveyed in a range of daily situations, errors in interpreting such facial expressions and, relatedly, understanding what potential behaviours such expressions signify could contribute to the social difficulties ID adults face. This is important because current initiatives such as 'personalisation' do not appear to have schemes supporting training in this area, and understanding the facial expressions of others is, after all, one of our most important non-verbal social communication tools.

Do therapeutic imagery practices affect physiological and emotional indicators of threat in high self-critics?

OBJECTIVES

Imagery is known to be a powerful means of stimulating various physiological processes and is increasingly used within standard psychological therapies. Compassion-focused imagery (CFI) has been used to stimulate affiliative emotion in people with mental health problems. However, evidence suggests that self-critical individuals may have particular difficulties in this domain with single trials. The aim of the present study was to further investigate the role of self-criticism in responsiveness to CFI by specifically pre-selecting participants based on trait self-criticism.

DESIGN

Using the Forms of Self-Criticism/Self-Reassuring Scale, 29 individuals from a total sample of 139 were pre-selected to determine how self-criticism impacts upon an initial instance of imagery.

METHODS

All participants took part in three activities: a control imagery intervention (useable data N = 25), a standard CFI intervention (useable data N = 25), and a non-intervention control (useable data N = 24). Physiological measurements (alpha amylase) as well as questionnaire measures of emotional responding (i.e., the Positive and Negative Affect Schedule, the Types of Positive Affect Scale, and the State Adult Attachment Scale) were taken before and after the different interventions.

RESULTS

Following both imagery interventions, repeated measures analyses revealed that alpha amylase increased significantly for high self-critics compared with low self-critics. High self-critics (HSC) also reported greater insecurity on entering the imagery session and more negative CFI experiences compared with low self-critics.

CONCLUSIONS

Data demonstrate that HSC respond negatively to imagery interventions in a single trial. This highlights that imagery focused therapies (e.g., CFI) need interventions that manage fears, blocks, and resistances to the techniques, particularly in HSC.

PRACTITIONER POINTS

An initial instance of imagery (e.g., CFI) can be frightening for people who have a tendency to be self-critical. This research provides examples of physiological and emotional responses to imagery type therapies in high and low self-critics, and associated clinical implications. Therapists may find it helpful to be mindful that when introducing imagery based therapies, highly self-critical patients need interventions that manage fears, blocks, and resistances to the techniques.

Early gamma-band activity as a function of threat processing in the extrastriate visual cortex

Various neuroimaging investigations have revealed that perception of emotional pictures is associated with greater visual cortex activity than their neutral counterparts. It has further been proposed that threat-related information is rapidly processed, suggesting that the modulation of visual cortex activity should occur at an early stage. Additional studies have demonstrated that oscillatory activity in the gamma band range (40–100 Hz) is associated with threat processing. Magnetoencephalography (MEG) was used to investigate such activity during perception of task-irrelevant, threat-related versus neutral facial expressions. Our results demonstrated a bilateral reduction in gamma band activity for expressions of threat, specifically anger, compared with neutral faces in extrastriate visual cortex (BA 18) within 50–250 ms of stimulus onset. These results suggest that gamma activity in visual cortex may play a role in affective modulation of visual processing, in particular with the perception of threat cues.

Predictors of painkiller dependence among people with pain in the general population

OBJECTIVES

Self-medication with painkillers is widespread and increasing, and evidence about influences on painkiller dependence is needed to inform efforts to prevent and treat problem painkiller use.

DESIGN

Online questionnaire survey.

PARTICIPANTS

People in the general population who had pain and used painkillers in the last month (N = 112).

MEASUREMENTS

Pain frequency and intensity, use of over-the-counter and prescription painkillers, risk of substance abuse (Screener and Opioid Assessment for Patients with Pain [SOAPP] scale), depression, anxiety, stress, alexithymia, pain catastrophizing, pain anxiety, pain self-efficacy, pain acceptance, mindfulness, self-compassion, and painkiller dependence (Leeds Dependence Questionnaire).

RESULTS

In multiple regression, the independent predictors of painkiller dependence were prescription painkiller use (β 0.21), SOAPP score (β 0.31), and pain acceptance (β -0.29). Prescription painkiller use mediated the influence of pain intensity. Alexithymia, anxiety, and pain acceptance all moderated the influence of pain.

CONCLUSIONS

The people most at risk of developing painkiller dependence are those who use prescription painkillers more frequently, who have a prior history of substance-related problems more generally, and who are less accepting of pain. Based on these findings, a preliminary model is presented with three types of influence on the development of painkiller dependence: 1) pain leading to painkiller use, 2) risk factors for substance-related problems irrespective of pain, and 3) psychological factors related to pain. The model could guide further research among the general population and high-risk groups, and acceptance-based interventions could be adapted and evaluated as methods to prevent and treat painkiller dependence.

In Search of Critical Thinking in Psychology: An Exploration of Student and Lecturer Understandings in Higher Education

This qualitative study of understandings of critical thinking in higher education aimed to identify themes that could help to demystify critical thinking and inform its more explicit incorporation in the psychology curriculum. Data collected from focus groups with 26 undergraduate psychology students and individual semistructured interviews with 4 psychology lecturers were examined using thematic analysis. The same key themes were identified from both student and lecturer data: ‘vague beginnings’, ‘conceptualizations’, ‘development and transitions’, and ‘learning strategies’. Both students and lecturers described critical thinking as implicit knowledge that develops through social interactions. The findings indicate the importance of explicit discussion about critical thinking, and could be used to inform the design and delivery of instructional methods to promote critical thinking.

Having a word with yourself: neural correlates of self-criticism and self-reassurance

Self-criticism is strongly correlated with a range of psychopathologies, such as depression, eating disorders and anxiety. In contrast, self-reassurance is inversely associated with such psychopathologies. Despite the importance of self-judgements and evaluations, little is known about the neurophysiology of these internal processes. The current study therefore used a novel fMRI task to investigate the neuronal correlates of self-criticism and self-reassurance. Participants were presented statements describing two types of scenario, with the instruction to either imagine being self-critical or self-reassuring in that situation. One scenario type focused on a personal setback, mistake or failure, which would elicit negative emotions, whilst the second was of a matched neutral event. Self-criticism was associated with activity in lateral prefrontal cortex (PFC) regions and dorsal anterior cingulate (dAC), therefore linking self-critical thinking to error processing and resolution, and also behavioural inhibition. Self-reassurance was associated with left temporal pole and insula activation, suggesting that efforts to be self-reassuring engage similar regions to expressing compassion and empathy towards others. Additionally, we found a dorsal/ventral PFC divide between an individual's tendency to be self-critical or self-reassuring. Using multiple regression analyses, dorsolateral PFC activity was positively correlated with high levels of self-criticism (assessed via self-report measure), suggesting greater error processing and behavioural inhibition in such individuals. Ventrolateral PFC activity was positively correlated with high self-reassurance. Our findings may have implications for the neural basis of a range of mood disorders that are characterised by a preoccupation with personal mistakes and failures, and a self-critical response to such events.

Identification of angry faces in the attentional blink

According to cognitive and neural theories of emotion, attentional processing of innate threat stimuli, such as angry facial expressions, is prioritised over neutral stimuli. To test this hypothesis, the present study used a modified version of the rapid serial visual presentation (RSVP) paradigm to investigate the effect of emotional face stimuli on the attentional blink (AB). The target stimuli were schematic faces which depicted threatening (angry), positive or neutral facial expressions. Results showed that performance accuracy was enhanced (i.e., the AB was reduced) on trials in which the second target was an angry face, rather than a neutral face. Results extend previous research by demonstrating that angry faces reduce the AB, and that this effect is found for schematic facial expressions. These findings further support the proposal that, when there is competition for attentional resources, threat stimuli are given higher priority in processing compared with non-threatening stimuli.

The spatial distribution and temporal dynamics of brain regions activated during the perception of object and non-object patterns

Both animal and human studies suggest that the efficiency with which we are able to grasp objects is attributable to a repertoire of motor signals derived directly from vision. This is in general agreement with the long-held belief that the automatic generation of motor signals by the perception of objects is based on the actions they afford. In this study, we used magnetoencephalography (MEG) to determine the spatial distribution and temporal dynamics of brain regions activated during passive viewing of object and non-object targets that varied in the extent to which they afforded a grasping action. Synthetic Aperture Magnetometry (SAM) was used to localize task-related oscillatory power changes within specific frequency bands, and the time course of activity within given regions-of-interest was determined by calculating time-frequency plots using a Morlet wavelet transform. Both single subject and group-averaged data on the spatial distribution of brain activity are presented. We show that: (i) significant reductions in 10-25 Hz activity within extrastriate cortex, occipito-temporal cortex, sensori-motor cortex and cerebellum were evident with passive viewing of both objects and non-objects; and (ii) reductions in oscillatory activity within the posterior part of the superior parietal cortex (area Ba7) were only evident with the perception of objects. Assuming that focal reductions in low-frequency oscillations (<30 Hz) reflect areas of heightened neural activity, we conclude that: (i) activity within a network of brain areas, including the sensori-motor cortex, is not critically dependent on stimulus type and may reflect general changes in visual attention; and (ii) the posterior part of the superior parietal cortex, area Ba7, is activated preferentially by objects and may play a role in computations related to grasping.
