Reactions to acceptance and rejection: Effects of level and sequence of relational evaluation

Abstract Two experiments examined the effects of various levels and sequences of acceptance and rejection on emotion, ratings of self and others, and behavior. In Experiment 1, participants who differed in agreeableness received one of five levels of acceptance or rejection feedback, believing that they either would or would not interact with the person who accepted or rejected them. In Experiment 2, participants who differed in rejection sensitivity received one of four patterns of feedback over time, reflecting constant acceptance, increasing acceptance, increasing rejection, or constant rejection. In both studies, rejection elicited greater anger, sadness, and hurt feelings than acceptance, as well as an increased tendency to aggress toward the rejector. In general, more extreme rejection did not lead to stronger reactions than mild rejection, but increasing rejection evoked more negative reactions than constant rejection. Agreeableness and rejection-sensitivity scores predicted participants’ responses but did not moderate the effects of interpersonal acceptance and rejection.

Creating Your Own Hostile Environment: A Laboratory Examination of Trait Aggressiveness and the Violence Escalation Cycle

A dyadic interactive aggression paradigm tested hypotheses from the General Aggression Model about how trait aggressiveness can create behaviorally hostile social environments. Pairs of college student participants competed in a modified reaction time task in which they repeatedly delivered and received each others punishments. The trait aggressiveness of both participants influenced the punishment intensities (aggression level) set by each member of the dyad on later trials. Furthermore, there was a pattern of escalation from early to later trials. These trait aggressiveness effects (both self and partner) on later aggressive behavior were largely mediated by partner aggression levels during early trials. Results also suggested two aggressive motives—hostile and instrumental—resulted from high partner aggression during early trials and these motives partially mediated the effects of trait aggressiveness and of early trial aggression on later aggressive behavior.
