The present study was designed to examine the effect of personalistic attribution and the intimacy level of disclosure on interpersonal attraction and reciprocity of self-disclosure. Two subjects were exposed to a disclosure of low (medium, high) intimacy level by a partner (confederate). In order to manipulate personalistic attribution, she (confederate) was asked in advance to choose whether to talk (disclose herself) to one or both of the subjects. Results confirmed a curvilinear relationship between the intimacy level of disclosure and interpersonal attraction. Reciprocity was higher when self-disclosure was at the medium level. However, no particular effect of personalistic attribution was confirmed.
