Abstract

In this future directions chapter, we look back at how the field of behavior genetics of cognition has changed in the transition from the twentieth century and acknowledge the gains that have been made. Then, we look forward to identify issues that are still in need of attention or resolution and new directions that we feel the field is prepared to explore. Since Waldman’s (1997) review of the field, we have made considerable progress in the following areas: focus on specific cognitive abilities; incorporating extremes of cognitive function and environmental background in our studies; searching for specific genetic loci associated with specific cognitive abilities; incorporating measures of environments in genetically informative studies; investigating gene by environment correlation and interaction; using developmental behavioral genetic methods to examine cognitive change; and using behavior genetics as a tool for examining the construct validity of intelligence. The fact that each issue is represented in more than one chapter in this volume, usually many chapters, highlights the fundamental integration of issues and approaches that characterizes the field of behavior genetics today. Common threads in the calls for future work include molecular genetics, environmental specificity, cognitive ability phenotypes, a broadening of the concept of interplay between genes and environments, and the continuing need for both quantitative and molecular approaches.
