The twin design can be applied to the study of emotion in a variety of ways that help illuminate why meaningful individual differences in emotion and related constructs emerge. At its most basic application, the twin design can identify relative genetic and environmental contributions to specific emotions; however, this methodological approach can also inform on (i) etiologic sources of overlap between different emotions; (ii) sources of stability and change in emotion constructs across time; and (iii) genetic and environmental effects shared across emotion constructs and psychopathology. This chapter summarizes findings from twin studies of basic emotions, complex emotions, emotion processes, and emotion and psychopathology. We discuss the implications of this research for intervention and molecular genetic work, and identify potential avenues for future twin research on emotion.
