Two studies explored the link between health care providers' patterns of nonverbal communication and therapeutic efficacy. In Study 1, physical therapists were videotaped during a session with a client. Brief samples of therapists' nonverbal behavior were rated by naive judges. Judges' ratings were then correlated with clients' physical, cognitive, and psychological functioning at admission, at discharge, and at 3 months following discharge. Therapists' distancing behavior was strongly correlated with short-and long-term decreases in their clients' physical and cognitive functioning. Distancing was expressed through a pattern of not smiling and looking away from the client. In contrast, facial expressiveness, as revealed through smiling, nodding, and frowning, was associated with short-and long-term improvements in functioning. In Study 2, elderly subjects perceived distancing behaviors of therapists more negatively than positive behaviors.

Integrative complexity, the interaction of conceptual and cognitive rules, is used in processing information. High integrative complexity people evaluate situations and make decisions diversely; low integrative complexity people reason simplistically and dichotomously. We examined the social psychology of South/North Korean relations in their correspondence by an integrative complexity coding process. Time series analysis predicted mean levels of integrative complexity for each half-year period between 1984 and 1997. Analysis showed that South/North Korean relations exert significant influence on integrative complexity levels. We also found a mutual effect of integrative complexity levels in the two. Major coordinative events relate to a decline in integrative complexity in the following half-year period. During South Korean presidential elections, correspondence integrative complexity levels decline in both.
