Using a sample of 73 undergraduates (28 men and 45 women) who had been involved in a dating relationship lasting at least 3 months, this study focuses on features of the family of origin that are emphasized within a social learning theory framework. The survey instrument encompassed physical aggression in family of origin, impact of aggression, identification with parents, and current aggression. The results support the hypothesis that there are features of the original learning situation that, depending on their level and coincidence with other features, contribute to the prediction of current aggression over and above the mere occurrence of family of origin aggression. The effects of additional features are multiplicative. 5 tables, 1 note, and 40 references
