Procedure- p's were 156 undergraduate students in a US university, paired into two-person dyads. Each dyad of unacquainted individuals engaged in a self-disclosure task over Skype. In the reciprocal disclosure condition, dyad members immediately took in turns asking and disclosing. In the non-reciprocal condition, one person asked the questions in the first interaction and the other disclosed; and in the second interaction (extended reciprocity) the roles switched. After each interaction, researchers assessed liking, closeness and perceived similarity.
