Carl Rogers (1965) stated that "the organism reacts to the field as it is experienced and perceived. This perceptual field is, for the individual, 'reality 1 . 11 Thus, according to phenomenological theory, experience and perception determine reality and consequently behavior. The present study tests the assumption that perception is related to behavior. The validity of the a perception of violence task as a predictor of rated aggressive behavior is tested. Sex is included as an independent variable because no data are available on sex differences for perception of violence.
