HAND MOVEMENT QUALITY: A NEGLECTED ASPECT OF NONVERBAL BEHAVIOR IN CLINICAL JUDGMENT AND PERSON PERCEPTION.

The article cites a study which analyzes hand movement quality. Movement quality is the way in which human movements are executed with respect to the dimensions of time and space. It is mentioned as an important diagnostic aspect of psychopathological disorders both in the old German "expression psychology" and in the psychiatric literature. This research studied movement quality by using objective physical measurements of movement parameters and subjective movement quality judgments and by comparing both approaches in terms of reliability and validity. This is done on the basis of clinical behavior samples that compared movements of psychiatric patients before and after therapy.
