Several polymorphisms relevant to dopamine and serotonin have been identified as potential contributors to individual differences in impulsivity versus self-control. Because impulsivity is a multifaceted construct, a need remains to examine more closely how various genes relate to different aspects of impulsivity. We examined four dopamine-related polymorphisms and the serotonin transporter as predictors of three aspects of impulsivity, two bearing on impulsive reactions to emotions and one on difficulty in completing intended actions. Early adversity was also examined as a potentiator of genetic effects. Undergraduates completed measures of impulsivity and early adversity and were genotyped. COMT, BDNF, DRD4, and 5HTTLPR (the latter two in interaction with early adversity) made independent contributions to prediction of Pervasive Influence of Feelings. BDNF made a contribution to Lack of Follow-Through. ANKK1 and 5HTTLPR (both in interaction with early adversity) made independent contributions to Feelings Trigger Action. Thus, five polymorphisms contributed to predicting impulsivity, but different polymorphisms related to different aspects.

In two large samples (combined N 1⁄4 31,045), we found a positive relationship between disgust sensitivity and political conservatism. This relationship held when controlling for a number of demographic variables as well as the ‘‘Big Five’’ personality traits. Disgust sensitivity was also associated with more conservative voting in the 2008 U.S. presidential election. In Study 2, we replicated ...

Why do people engage in self-punishment when they feel guilty? This article aims to bridge discrepant views that portray guilt either as an adaptive social emotion that is vital to the maintenance of social relations or as a maladaptive emotion that produces a host of negative self-directed responses. An experiment investigating the impact of various audience conditions on self-punishment tende...

An examination of emotions reported on 12 million personal blogs along with a series of surveys and laboratory experiments shows that the meaning of happiness is not fixed; instead, it systematically shifts over the course of one’s lifetime. Whereas younger people are more likely to associate happiness with excitement, as they get older, they become more likely to associate happiness with peace...

This article investigates the phenomenon of interindividual rivalry and its consequences for motivation and task performance. Two studies of adults from the general population found that rivalry, as compared to nonrival competition, was associated with increased motivation and performance, controlling for tangible stakes, dislike, and other factors. Then, a large-scale archival study of long-di...

Past work has demonstrated that Big Five personality traits both predict relationship success and respond to changes in relationship status. The current study extends this work by examining how developments on the Big Five traits correspond to another important social outcome in adulthood, social well-being. Using the Mid-Life Development in the U.S. longitudinal data sample of adults, the auth...

Inferences from faces can predict important real-world outcomes. But little is known about the stability of these effects. Here the authors find that inferences of power from photos of the faces of the managing partners of America’s top 100 law firms significantly corresponded to their success as leaders, as measured by the amounts of profits that their firms earned. More interesting, this rela...
