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.).

The Impact

As recently as 2005, John Alford and colleagues surprised political science with their twin study that found empirical evidence of the genetic transmission of political attitudes and behaviors. Reactions in the field were mixed, but one thing is for sure: it is not time to mourn the social part of the social sciences. Genetics is not the deterministic mechanism that social scientists often assume it to be. No specific part of DNA is responsible for anything but minute, indirect effects on political orientations. Genes express themselves differently in different contexts, suggesting that the political phenomenon behavioral political scientists take for granted may be quite volatile; hence, the impact of genetics is also much less stable in its foundations than initially assumed. Twin studies can offer a unique and powerful avenue to study these behavioral processes as they are more powerful than cross-sectional (or even longitudinal) studies not only for understanding heritability but also for asserting the direction of causation, the social (and, of course, genetic) pathways that explain how political phenomena are related to each other. This chapter aims to take the reader through this journey that political science has gone through over the past decade and a half and point to the synergies behavioral political science and behavioral genetics offer to the advancement of the discipline.
