This book examines patterns of
interpersonal coordination in a treatment group. Findings
reported herein were obtained from videorecording and
analysis of twelve one-hour sessions. A new construct was
introduced to the study of group behaviour. Interpersonal
coordination was imported to this inquiry as a means of
examining changing patterns of nonverbal behaviour in the
treatment group under study. Interpersonal coordination was
defined as comprising two behavioural elements, behavioural
congruence and interpersonal synchrony. Bivariate
cross-correlational time series analysis and hierarchical
cluster analysis are employed to examine the changing
patterns of interpersonal relationships during each
session. Bivariate cross- correlational time series
analysis was also utilized to examine the relationship
between the behavioural elements of interpersonal
coordination and the changing group properties of empathy
and cohesion. The influence of significant events and
interpersonal relationships were explored and compared to
significant relationships found in interpersonal
coordination between group members.
