Evolutionary concepts suggest the existence of special patterns of behaviors which are an effective way to achieve bonds (Eibl-Eibesfeldt, 1987). The results of psychological research, using scenarios involving behavior consistent with social norms, confirm these suggestions. Such behavioral patterns indeed fulfill their bonding function, both in the initial phase of forming a close relationship (Kuczynska, 1991, 1993.1999), as well as in maintaining it (Kuczynska, 1998). They have a positive influence on the affective, cognitive and behavioral reactions of individuals to whom they are presented (Kuczynska, 1998). The purpose of this research was twofold: to test whether these behaviors would also be so effective when they are inconsistent with social norms, and to determine what part social norms play in the affective, cognitive and behavioral reactions of people towards whom such behaviors are presented. One hundred sixty people took part in the study. A pair of specially trained researchers presented four types of behaviors: neutral and bonding behaviors consistent with social norms, and friendly and sexual behaviors inconsistent with social standards. The results prove that the subjects' reactions depend on the degree of conformity between the behaviors and social norms and on the strength of their bonding.
