The competition dynamics of approach and avoidance motivations following interpersonal transgression

Abstract

Two behavioral motivations coexist in transgressors following an interpersonal transgression—approaching and compensating the victim and avoiding the victim. Little is known about how these motivations arise, compete, and drive transgressors’ decisions. The present study adopted a social interaction task to manipulate participants’ (i.e., the transgressor) responsibility for another’s (i.e., the victim) monetary loss and measure the participants’ tradeoff between compensating the victim and avoiding face-to-face interactions with the victim. Following each transgression, participants used a computer mouse to choose between two options differing in the amount of compensation to the victim and the probability of face-to-face contact with the victim. Results showed that as participants’ responsibility increased, 1) the decision weights on contact avoidance relative to compensation increased, and 2) the onset of the contact-avoidance attribute was expedited and that of the compensation attribute was delayed. These results demonstrate how competing social motivations following transgression evolve and determine social decision-making and shed light on how social-affective state modulates the dynamics of decision-making in general.
