A Comparison of Structural Brain Imaging Findings in Autism Spectrum Disorder and Attention-Deficit Hyperactivity Disorder

ASD and ADHD are regarded as distinct disorders in the current DSM-5. However, recent research and the RDoC initiative are recognizing considerable overlap in the clinical presentation of ASD, ADHD, and other neurodevelopmental disorders. In spite of numerous neuroimaging findings in ASD and ADHD, the extent to which either of the above views are supported remains equivocal. Here we compare structural MRI and DTI literature in ASD and ADHD. Our main findings reveal both distinct and shared neural features. Distinct expressions were in total brain volume (ASD: increased volume, ADHD: decreased volume), amygdala (ASD: overgrowth, ADHD: normal), and internal capsule (ASD: unclear, ADHD: reduced FA in DTI). Considerable overlap was noted in the corpus callosum and cerebellum (lower volume in structural MRI and decreased FA in DTI), and superior longitudinal fasciculus (reduced FA in DTI). In addition, we identify brain regions which have not been studied in depth and require more research. We discuss relationships between brain features and symptomatology. We conclude by addressing limitations of current neuroimaging research and offer approaches that account for clinical heterogeneity to better distinguish brain-behavior relationships.     

The sexual dimorphic association of cardiorespiratory fitness to working memory in children

The present investigation examined the sexual dimorphic patterns of cardiorespiratory fitness to working memory in preadolescent children (age range: 7.7–10.9). Data were collected in three separate studies (Study 1: n = 97, 42 females; Study 2: n = 95, 45 females; Study 3: n = 84, 37 females). All participants completed a cardiorespiratory fitness assessment in addition to a specific measure of working memory (i.e. the operation span task, the n‐back task, or the Sternberg task). Results from all three samples revealed that higher cardiorespiratory fitness levels were associated with better working memory performance only for males with no such relation observed for females. In addition, the sexually dimorphic pattern was selective for the most challenging working memory conditions in each task. Together, these findings reveal new evidence that cardiorespiratory fitness is selectively related to better working memory performance for male children. This investigation provides additional insight into how interventions aimed at improving fitness may influence cognitive development differentially among preadolescent children.     

The effect of geographic indication in advertising background pictures on product evaluation: The moderating role of familiarity

This study investigates whether geographic indications in the backgrounds of advertising pictures might affect the viewer's evaluation of a product. The findings reveal that participants in the proximal geographic indication evaluated the product more favourably than those in the distal geographic indication when they were exposed to feasibility‐related information. By contrast, participants in the distal geographic indication evaluated the product more favourably than those in the proximal geographic indication when they were exposed to desirability‐related information. However, familiarity with geographic indications eliminated this effect.     

The Influence of Neighborhood Aesthetics,Safety, and Social Cohesion on Perceived Stress in Disadvantaged Communities

Limited research has explored how specific elements of physical and social environments influence mental health indicators such as perceived stress, or whether such associations are moderated by gender. This study examined the relationship between selected neighborhood characteristics and perceived stress levels within a primarily low‐income, older, African‐American population in a mid‐sized city in the Southeastern U.S. Residents (n = 394; mean age=55.3 years, 70.9% female, 89.3% African American) from eight historically disadvantaged neighborhoods completed surveys measuring perceptions of neighborhood safety, social cohesion, aesthetics, and stress. Multivariate linear regression models examined the association between each of the three neighborhood characteristics and perceived stress. Greater perceived safety, improved neighborhood aesthetics, and social cohesion were significantly associated with lower perceived stress. These associations were not moderated by gender. These findings suggest that improving social attributes of neighborhoods may have positive impacts on stress and related benefits for population health. Future research should examine how neighborhood characteristics influence stress over time.     

LearningRx Cognitive Training Effects in Children Ages 8–14: A Randomized Controlled Trial

In a randomized controlled study, we examined the effects of a one‐on‐one cognitive training program on memory, visual and auditory processing, processing speed, reasoning, attention, and General Intellectual Ability (GIA) score for students ages 8–14. Participants were randomly assigned to either an experimental group to complete 60 h of cognitive training or to a wait‐list control group. The purpose of the study was to examine changes in multiple cognitive skills after completing cognitive training with ThinkRx, a LearningRx program. Results showed statistically significant differences between groups on all outcome measures except for attention. Implications, limitations, and suggestions for future research are examined. © 2016 The Authors Applied Cognitive Psychology Published by John Wiley & Sons Ltd.     

Sustainable Technologies and Transdisciplinary Futures: From Collaborative Design to Digital Fabrication

This paper argues for hands-on, contextual and problem-solving collaborations, that is, for a transdisciplinary approach that establishes direct connections between social and technical disciplines. It is based on our experience as a team of researchers at the Vitruvius Fab Lab (Digital Fabrication Laboratory) of ISCTE-IUL (University Institute of Lisbon, Portugal). The paper presents a particular research and learning initiative–STTF2013 Summer School ‘Sustainable Technologies and Transdisciplinary Futures: From Collaborative Design to Digital Fabrication’, which served as a testbed for our transdisciplinary, critical and open approach. We address its rationale and main challenges, while also discussing recommendations for other transdisciplinary projects striving to integrate social and technical disciplines in research and innovation.
