However; it is unclear whether these personality traits are associated with magnitude of affective reactions (Affective-Reactivity view), with levels of tonic affect (Affect-Level view), or with both.

Are the methods and strategies that evolutionary psychologists use to generate and test hypotheses scientifically defensible? This target article addresses this question by reviewing principles of philosophy of science that are used to construct and evaluate metatheoretical research programs and applying these principles to evaluate evolutionary psychology.(More)
Two online studies evaluated the misperception of sexual and romantic interests in established relationships and tested four hypotheses: a simple sex-difference hypothesis, a projection hypothesis, a mate value hypothesis, and a mediation hypothesis.

In the first study, faces of fashion models representing less prestigious apparel brands(More)
Theories about why immoral behaviors carry a large amount of attributional weight tend to emphasize traditional cognitive variables. In contrast, the authors propose that the degree of negative affect that these behaviors induce in observers is largely responsible for their attributional weight. Studies 1 and 2 demonstrate an association between the amount(More)
A central goal of our target article was to evaluate the soundness of evolutionary psychology’s epistemology in relation to the critical claim that evolutionary explanations are unfalsifiable. None of the 16 commentators challenge our central assertion—that the methods and strategies employed by evolutionary psychologists to generate and test hypotheses are(More)
Historically, evolutionary perspectives on emotion have focused on two broad perspectives: 1) Emotions-asSentiments and 2) Emotions-as-Signals (Bowlby, 1969). My research embraces both views by exploring the idea that emotions are “designed” as cognitive systems for generating “affective information” (Schwarz & Clore, 1983; Ketelaar & Clore, 1997). Rather(More)
EMOTLAB software creates a virtual social environment in which individuals interact via computer with a virtual interaction partner in a series of economic bargaining games. The virtual partner appears on the participant's computer screen as a digital image (e.g., video or picture file) during each trial. A key feature of EMOTLAB software is its ability to(More)
