Interpersonal behaviour of individuals in five tasks (individual performance, two dyadic tasks, two small-group tasks) was videotaped and coded on 11 psychomotor categories concerning (a) movements regulating interaction, (b) indications of tension, and (c) temperamental acts. The individual consistencies were examined on the basis of correlational analyses and task similarities. The consistency of individual psychomotor behaviour across all the tasks was highest in the number of selfinitiated acts (psychomotor activeness). Consistency was also found in the total tension score and the utilization of largelnamow space, while the effect of the particular tasks was clearly demonstrated in the other categories of psychomotor style. Both communication and disposition interpretations of psychomotor styles were considered in the explanation of the results, and some methodological factors reflected in the interpretations were presented.
