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.

Individual differences in cognitive ability are predicted to covary with other behavioural traits such as exploration and boldness. Selection within different habitats may act to either enhance or break down covariance among traits; alternatively, changing the environmental context in which traits are assessed may result in plasticity that alters trait covariance. Pond snails, Lymnaea stagnalis , from two laboratory strains (more than 20 generations in captivity) and F1 laboratory reared from six wild populations were tested for long-term memory and exploration traits (speed and thigmotaxis) following maintenance in grouped and isolated conditions to determine if isolation: (i) alters memory and exploration; and (ii) alters covariance between memory and exploration. Populations that demonstrated strong memory formation (longer duration) under grouped conditions demonstrated weaker memory formation and reduced both speed and thigmotaxis following isolation. In wild populations, snails showed no relationship between memory and exploration in grouped conditions; however, following isolation, exploration behaviour was negatively correlated with memory, i.e. slow-explorers showing low levels of thigmotaxis formed stronger memories. Laboratory strains demonstrated no covariance among exploration traits and memory independent of context. Together these data demonstrate that the relationship between cognition and exploration traits can depend on both habitat and context-specific trait plasticity. This article is part of the theme issue ‘Causes and consequences of individual differences in cognitive abilities’.
