Virtuous Play: The Ethics,Pleasures, and Burdens of Brain Training

Through normative appeals of cognitive enhancement, the brain has become a site of both promise and peril. Displaying oneself as ethically sound may now include showing requisite care for cognitive capacities. Moreover, enhancing our cognitive reserves is framed as aspirational means of averting neurodegenerative disease and neoliberal precarity. Such demanding labours of self-care warrant close scrutiny. Promissory discourses proclaim our ‘neuroplasticity’, encouraging subjects to work on endlessly improvable functional capacities that hold labour market value. Yet a ‘fun morality’ is equally prevalent in today’s experiential economies. Neuro-enhancement is thus sold not as an ascetic chore, but an ecstatic potential. Hope, fear, pleasure, and ethical conduct are, therefore, all closely entwined in the ‘virtuous play’ of ‘brain training’, where commercial entities use digital platforms for game-based tasks designed to enhance cognitive abilities. These services are typically promoted through appeals to our dutiful biocitizenship. This type of virtuous play is increasingly the means by which subjects produce themselves as simultaneously pleasure-seeking, productive, and resoundingly ‘well’. However, this understanding of virtuosity is often narrowly derived—reduced to ‘active ageing’, corporate-style ‘neurohacking’, and ‘brain profiles’—that threaten to foreclose other ways of imagining well-being. In failing to recognize the neoliberal underpinnings of virtuous play we entrench burdensome attachments to emerging modes of personal enhancement. Against these seductive appeals of combining pleasure with self-improvement, we must cultivate a critical reflexivity regarding exactly how ‘enhancement’ is conceived, opening room for lines of possibility outside of currently dominant frameworks.     

Integration processes during frequency graph comprehension: Performance and eye movements while processing tree maps versus pie charts

Frequency graph types differ in the way how data are translated into visual representations. We compared 2 visualization methods, a traditional circular representation (pie chart) and a rectangular representation (constant column width tree map), which were hypothesized to differ regarding the cognitive ease of visual comparison processes. Performance was evaluated in tasks involving proportion and comparison judgments under both highly controlled and more realistic circumstances. The results showed performance benefits (in terms of reduced response times or error rates) for rectangular representations. Additional eye movement analyses revealed that this benefit was mainly due to a facilitation of scanning the graph for relevant information. The results suggest that facilitating comparison processes by representing the critical variable in less complex visual dimensions (i.e., straight length with constant orientation instead of surface area or curved length) eventually enhances the efficiency of integration processes during graph comprehension.     

Neurocognitive outcomes in children with unilateral basal ganglia arterial ischemic stroke and secondary hemidystonia

Dystonia is a movement disorder that involves excessive, involuntary muscle contractions resulting in repetitive movements and/or abnormal posturing. One common cause of unilateral dystonia in childhood is ischemic stroke involving the basal ganglia and/or thalamus. Virtually nothing is known about neuropsychological outcomes in children who have dystonia following basal ganglia stroke. The present study explored whether or not children with secondary dystonia experience additional cognitive challenges when compared to children with similar patterns of brain injury, but no dystonia. We examined intellectual function, academics, and several aspects of executive function in children with unilateral basal ganglia stroke during childhood, comparing those with dystonia and those without. Although groups did not differ in terms of lesion size, we found significantly lower performance on measures of verbal and nonverbal reasoning, inhibitory control, and academic ability in children with secondary dystonia compared to those without. In contrast, there were no significant group differences on parent ratings of their child’s executive function in daily life. These findings suggest that maladaptive reorganization following basal ganglia stroke may contribute to the development of secondary dystonia and also to poor intellectual and academic outcomes in this group.     

Early motor development and cognitive abilities among Mexican preschoolers

Psychomotricity plays a very important role in children’s development, especially for learning involving reading–writing and mathematical calculations. Evaluate motor development in children 3 years old and its relationship with their cognitive abilities at the age of 5 years. Based on a cohort study, we analyzed the information about motor performance evaluated at 3 years old by Peabody Motor Scale and cognitive abilities at 5 years old. The association was estimated using linear regression models adjusted by mother’s intelligence quotient, sex, Bayley mental development index at 18 months, and quality of the environment at home (HOME scale). 148 children whose motor performance was determined at age 3 and was evaluated later at age 5 to determine their cognitive abilities. Cognitive abilities (verbal, quantitative, and memory) measured by McCarthy Scales. Significant positive associations were observed between stationary balance at age 3 with verbal abilities (β = 0.67, p = .04) and memory (β = 0.81, p = .02) at 5 years. Grasping and visual-motor integration were significant and positively associated with quantitative abilities (β = 0.74, p = .005; β = 0.61, p = .01) and memory (β = 2.11, p = .001; β = 1.74, p = .004). The results suggest that early motor performance contributes to the establishment of cognitive abilities at 5 years. Evaluation and early motor stimulation before the child is faced with formal learning likely helps to create neuronal networks that facilitate the acquisition of academic knowledge.     

Causes of cultural disparity: Switches,tuners, and the cognitive science of religion

Cultural disparity – the variation across cultural traits such as knowledge, skill, and belief – is a complex phenomenon, studied by a number of researchers with an expanding empirical toolkit. While there is a growing consensus as to the processes that generate cultural variation and change, general explanatory frameworks require additional tools for identifying, organizing, and relating the complex causes that underpin the production of cultural disparity. Here I develop a case study in the cognitive science of religion and demonstrate how concepts and distinctions drawn from work on contrastive explanation and manipulationist accounts of causation provide such tools for distinguishing explanatory levels, organizing causal narratives, and accounting for cross-cultural patterns.     

Trust in organization as a moderator of the relationship between self‐efficacy and workplace outcomes: A social cognitive theory‐based examination

Drawing on a social cognitive theory perspective, we contend that an employee's trust in oneself, or self‐efficacy, will interact with the individual's trust in the system, or trust in organization, to predict job attitudes and behaviours. Specifically, we expected that self‐efficacy would have stronger effects on job attitudes (job satisfaction and turnover intentions) and behaviours (task performance and organizational citizenship behaviours) to the degree to which employees perceive high levels of trust in organization. Using data collected from 300 employees and their respective supervisors at a manufacturing organization in Turkey across three waves, we found that self‐efficacy had more positive effects on job satisfaction, task performance, and citizenship behaviours when trust in organization was high. Interestingly, self‐efficacy had a positive effect on turnover intentions when trust in organization was low, indicating that high trust in organization buffered the effects of self‐efficacy on intentions to leave. The results suggest that the motivational value of trust in oneself is stronger to the degree to which employees also have high trust in the system, whereas low trust in system neutralizes the motivational benefits of self‐efficacy.

Practitioner points

• Practicing managers should not only invest in increasing self‐efficacy of their employees, but also invest in building trust to improve employees’ attitudes, behaviours, and performance. This is because when employee trust in organization is high, employee self‐efficacy has greater potential to have a positive influence over job satisfaction, task performance, and organizational citizenship behaviours.
• Self‐efficacy may actually increase an employee's desire to leave the organization when organizational conditions are unfavourable, such as in the case of low trust in the organization. Practicing managers should be aware that employees who have high levels of confidence may be at higher risk of turnover when they are unhappy with the organization.

     

“THE NEW SCIENCE OF HEALTH AND HAPPINESS”: INVESTIGATING BUDDHIST ENGAGEMENTS WITH THE SCIENTIFIC STUDY OF MEDITATION

Clinical and neuroscientific studies of Buddhist meditation practices are frequent topics in the news media, and have helped certain practices (such as mindfulness) achieve mainstream cultural status. Buddhists have reacted by using these studies in a number of ways. Some deploy the studies to show the compatibility of science and Buddhism, often using the authority of science to lend credence to Buddhism. Other Buddhists use meditation studies to demonstrate the superiority of Buddhism over science. Within inter‐Buddhist debates, meditation studies are used to argue for changes in practice or belief, but also sometimes to reinforce certain traditional practices. Benjamin Zeller's threefold categorization of religious groups’ attitudes toward science (guide, replace, absorb) and José Ignacio Cabezón's three ideal types of relationships between Buddhism and science (conflict/ambivalence, compatibility/identity, complementarity) contribute to analysis of Buddhist uses of scientific studies of meditation.     

Journalism as Model for Civic and Information Literacies

Journalism can serve as a generative disciplinary context for developing civic and information literacies needed to meaningfully participate in an increasingly networked and mediated public sphere. Using interviews with journalists, we developed a cognitive task analysis model, identifying an iterative sequence of production and domain-specific cognitive constructs of journalism expertise. We diagnose common discrepancies between professional practices and typical youth journalism pedagogies, and offer suggestions for teaching participatory politics and civic literacies through journalism.     

Attention and the Cognitive Penetrability of Perception

One sceptical rejoinder to those who claim that sensory perception is cognitively penetrable is to appeal to the involvement of spatial attention. While the sceptic is correct that some putative cases are accurately deflected in this way, the rejoinder oversimplifies the possible roles that attention might play in relevant contexts. This paper identifies alternative ways that selective attention might play a role in cognitive effects on perception. What emerges is a plausible and well-evidenced mental schema that describes attention-mediated cognitive penetration.     

Sample size determination for a matched-pairs study with incomplete data using exact approach

This research was motivated by a clinical trial design for a cognitive study. The pilot study was a matched-pairs design where some data are missing, specifically the missing data coming at the end of the study. Existing approaches to determine sample size are all based on asymptotic approaches (e.g., the generalized estimating equation (GEE) approach). When the sample size in a clinical trial is small to medium, these asymptotic approaches may not be appropriate for use due to the unsatisfactory Type I and II error rates. For this reason, we consider the exact unconditional approach to compute the sample size for a matched-pairs study with incomplete data. Recommendations are made for each possible missingness pattern by comparing the exact sample sizes based on three commonly used test statistics, with the existing sample size calculation based on the GEE approach. An example from a real surgeon-reviewers study is used to illustrate the application of the exact sample size calculation in study designs.
