Actigraphic sleep and cortisol in middle childhood: A multivariate behavioral genetics model

This paper is an introduction to behavioral genetics for researchers and practioners in language development and disorders. The specific aims are to illustrate some essential concepts and to show how behavioral genetic research can be applied to the language sciences. Past genetic research on language-related traits has tended to focus on simple etiology (i.e., the heritability or familiality of language skills). The current state of the art, however, suggests that great promise lies in addressing more complex questions through behavioral genetic paradigms. In terms of future goals it is suggested that: (a) more behavioral genetic work of all types should be done—including replications and expansions of preliminary studies already in print; (b) work should focus on fine-grained, theory-based phenotypes with research designs that can address complex questions in language development; and (c) work in this area should utilize a variety of samples and methods (e.g., twin and family samples, heritability and segregation analyses, linkage and association tests, etc.).

Linguistic Backgrounds

Many countries face the problem of skill shortage in traditionally male occupations. Individuals’ development of vocational interests and employment goals starts as early as in middle childhood and is strongly influenced by perceptions of job accessibility (status and difficulty) and self-efficacy beliefs. In this study, we tested a linguistic intervention to strengthen children’s self-efficacy toward stereotypically male occupations. Two classroom experiments with 591 primary school students from two different linguistic backgrounds (Dutch or German) showed that the presentation of occupational titles in pair forms (e.g., Ingenieurinnen und Ingenieure, female and male engineers), rather than in generic masculine forms (Ingenieure, plural for engineers), boosted children’s self-efficacy with regard to traditionally male occupations, with the effect fully being mediated by perceptions that the jobs are not as difficult as gender stereotypes suggest. The discussion focuses on linguistic interventions as a means to increase children’s self-efficacy toward traditionally male occupations.

Context Dependent

Changing environmental context during encoding can influence episodic memory. This study examined the memorial consequences of environmental context change in children. Kindergartners, first and fourth graders, and young adults studied two lists of items, either in the same room (no context change) or in two different rooms (context change), and subsequently were tested on the two lists in the room in which the second list was encoded. As expected, in adults, the context change impaired recall of the first list and improved recall of the second. Whereas fourth graders showed the same pattern of results as adults, in both kindergartners and first graders no memorial effects of the context change arose. The results indicate that the two effects of environmental context change develop contemporaneously over middle childhood and reach maturity at the end of the elementary school days. The findings are discussed in light of both retrieval-based and encoding-based accounts of context-dependent memory.
