Abstract. In this study, we want to investigate the impact of dyadic implicit and explicit power motive combinations and interactions on the performance in a joint action task. The specific direction of these effects is currently an open question as there are no studies of dyadic motive effects in joint action tasks. To this end, N = 27 same-sex dyads were recruited to play a self-programmed maze game in which both participants had to navigate a ball thorugh a maze moving one joystick each. During the task, the participants were responsible for a different movemet direction, i.e., one participant being responsible for the horizontal, the other for the vertical movement. The direction changed throughout the trials. In the maze, there were holes in which the ball could fall. Explicit (Unified Motive Scale, Schönbrodt & Gerstenberg, 2012) and implicit (Picture Story Exercise; Winter, 1994) motives, round time, errors and speaking times of the participants were measured. On the base of the previous findings, we expected (1a) that dyads with a high power motive will perform worse than low power motivated dyads, (1b) that dyads with high power motive difference will perform better than dyads with similar scores, and (2) high power motivated individuals will speak more.

Abstract. In Germany, approximately two thirds are in a relationship, more than half of them married. Most of the relationships are monogamous. However, 15-32% of German adults report actual sexual infidelity. The psychological variable sociosexuality, that is, “people’s willingness to engage in uncommitted sexual relationships” (Penke & Asendorpf, 2008, p. 1113), seems to be correlated with sexual infidelity. Moreover, both infidelity and sociosexuality are negatively correlated with relationship satisfaction. Given these findings, it seems plausible that actual infidelty may moderate the relationship between sociosexuality and relationship satisfaction. Specifically, high sociosexual individuals may have the drive to engage in uncommited (additional) sexual relationships that may be satisfied by betraying the partner, resulting in a higher realtionship satisfaction. On the other hand, low sociosexual individuals should not have this drive and, thus, have a higher relationship satisfaction when not betraying their partner. For investigating these hypothesis, a data set of 335 heterosexual couples was analyzed and an Actor-Partner Interdependence Model was applied.
