The aim of this study was to empirically verify a series of hypotheses on the role of time perspective (TP) in predicting aggression, formulated on the basis of TP Theory and models of aggression. Three hundred participants completed the Zimbardo Time Perspective Inventory (ZTPI) and the Aggression Questionnaire (AQ). Analysis revealed numerous significant relationships between TP dimensions and aggression. In particular, individuals scoring high on Past Negative, Present Fatalistic, and Present Hedonistic were more prone to aggressive feelings, and, in consequence, aggressive behavior. These relationships were, however, strongly attenuated in individuals with high levels of two remaining TPs -Past Positive and Future. The results provide evidence that the temporal perspective people use to structure their experience into time horizons may play a significant role in the intensity and dynamics of aggression. We discuss our results from the perspectives of psychological theories of aggression and TP.
