Motion Sensitivity

Sensitivity to global visual motion has been proposed as a signature of brain development, related to the dorsal rather than ventral cortical stream. Thresholds for global motion have been found to be elevated more than for global static form in many developmental disorders, leading to the idea of “dorsal stream vulnerability.” Here we explore the association of global motion thresholds with individual differences in children's brain development, in a group of typically developing 5- to 12-year-olds. Good performance was associated with a relative increase in parietal lobe surface area, most strongly around the intraparietal sulcus and decrease in occipital area. In line with the involvement of intraparietal sulcus, areas in visuospatial and numerical cognition, we also found that global motion performance was correlated with tests of visuomotor integration and numerical skills. Individual differences in global form detection showed none of these anatomical or cognitive correlations. This suggests that the correlations with motion sensitivity are unlikely to reflect general perceptual or attentional abilities required for both form and motion. We conclude that individual developmental variations in global motion processing are not linked to greater area in the extrastriate visual areas, which initially process such motion, but in the parietal systems that make decisions based on this information. The overlap with visuospatial and numerical abilities may indicate the anatomical substrate of the “dorsal stream vulnerability” proposed as characterizing neurodevelopmental disorders.

It is well-established that as people age, deterioration in cognitive abilities including processing speed, memory, and cognitive flexibility occurs, although vast individual differences occur in the rate and consequences of this decline (Christensen, 2001). Anxiety and depression in late life are also associated with specific cognitive deficits in memory and executive functioning that may impact on new learning (Yochim et al., 2013). Therefore, it is possible that cognitive changes make it more difficult for older adults to learn how to change their thinking particularly in the context of psychological therapy.

Individual differences in children’s cognitive abilities impact life and health outcomes. What factors influence these individual differences during development? Here we test whether children’s environments predict cognitive performance, independent of well- characterized socioeconomic effects. We analyzed data from 9002 9–10-year-olds from the Adolescent Brain Cognitive Development Study, an ongoing longitudinal study with community samples across the U.S.A. Using youth- and caregiver-report questionnaires and national database registries (e.g., neighborhood crime, walkability), we defined principal components summarizing children’s home, school, neighborhood, and cultural environments. In two independent samples (ns = 3475, 5527), environmental components explained unique variance in children’s general cognitive ability, executive functioning, and learning/memory abilities. Furthermore, increased neighborhood enrichment was associated with a decreased relationship between sociodemographics and general cognitive abilities. Thus, the environment explains unique variance in cognitive performance in development and should be considered alongside sociodemographic factors to understand brain functioning and behavior.

Individual differences in resource availability, and the patterns of cognitive abilities they contribute to, are important to:• explaining variation between learners in the effectiveness of second language (L2) instructional treatments;• describing differences in implicit, incidental and explicit L2 learning processes; and• explaining child-adult differences in acquisition processes, and therefore to any general theory of second language acquisition (SLA).In this article I describe a framework for research into the effects of cognitive abilities on SLA which is based on four interlocking hypotheses. These hypotheses are drawn from research in psychology, education and SLA and, where possible, I present evidence to support each of them. The hypotheses are:1) the Aptitude Complex Hypothesis;2) the Ability Differentiation Hypothesis;3) the Fundamental Difference Hypothesis; and4) the Fundamental Similarity Hypothesis.The hypotheses, and the relationships between them, define an Aptitude Complex/Ability Differentiation framework for further examining the influence of individual differences in cognitive abilities on SLA, and for developing a theoretically motivated measure of language learning aptitude. I argue that such research should adopt the interactionist approach described by Snow (1994) to identifying individual difference/learning condition interactions at a number of levels. I illustrate some of these interactions.
