Nature-nurture reconceptualized in developmental perspective: a bioecological model.

In response to Anastasi's (1958) long-standing challenge, the authors propose an empirically testable theoretical model that (a) goes beyond and qualifies the established behavioral genetics paradigm by allowing for nonadditive synergistic effects, direct measures of the environment, and mechanisms of organism-environment interaction, called proximal processes, through which genotypes are transformed into phenotypes; (b) hypothesizes that estimates of heritability (e.g., h2) increase markedly with the magnitude of proximal processes; (c) demonstrates that heritability measures the proportion of variation in individual differences attributable only to actualized genetic potential, with the degree of nonactualized potential remaining unknown; (d) proposes that, by enhancing proximal processes and environments, it is possible to increase the extent of actualized genetic potentials for developmental competence.

"Don't forget to take the cupcakes out of the oven": prospective memory, strategic time-monitoring, and context.

Strategies employed by children in tasks requiring prospective memory (i.e., remembering to do something in the future) were investigated to illuminate the nature of the processes involved, and their developmental and contextual determinants. Efficient strategy use was expected to increase with age but to decrease in an unfamiliar setting or on a task associated with higher sex-role expectations. Children were instructed to perform future activities after waiting 30 min. Children's clock-checking during the waiting period was assessed in their own homes or a university psychophysics laboratory. As predicted, strategic time-monitoring occurred less frequently in the laboratory than in the home. The anticipated differences associated with higher sex-role expectations and age were most salient for older boys in the laboratory setting. The findings indicate that, when observed in a familiar setting, children can be shown to employ sophisticated cognitive strategies. Emphasis is placed on the scientific power of the laboratory as a contrasting context for illuminating developmental processes.
