Human behavior is structured by serial order and timing of functionally related groups of movements with a duration of a few seconds. These elementary action units have been described in ethological studies during unstaged everyday behavior, but not during interview sessions. Psychomotor alterations are relevant for differential diagnosis and treatment, and psychiatric patients are generally evaluated during interview sessions. Therefore the time structure of upper limb movements ( n=764) of healthy subjects ( n=22) were studied using videotaped interviews and frame-by-frame analysis and compared to movements ( n=530) of unstaged human everyday behavior ( n=154). The number of action units, but not their duration, was correlated inversely with self-reported impairment of mood and pleasure experience in healthy persons. The temporal distribution of movements in interview sessions did not differ from the time patterns of everyday behavior. This method could be a promising tool to investigate time patterns of movements and psychomotor alterations in psychiatric patients during interview sessions. [ABSTRACT FROM AUTHOR] |
