Effect of timing of communicator identification and level of source credibility on attitude

This study investigated whether roommates who were similar in their communication traits would express more satisfaction with and affinity for their roommates. Specifically, the communication traits of willingness to communicate, interpersonal communication competence, and verbal aggressiveness were considered. Participants (college students and their roommates) completed measures of their own communication traits and their feelings about their roommates. Results showed that roommates who were prosocially similar (when both roommates were high in willingness to communicate, when both roommates were high in interpersonal communication competence, and when both roommates were low in verbal aggressiveness) reported the highest roommate satisfaction and liking.
