ABSTRACT

There is a long history of debate as to whether schizophrenics are over or under aroused physiologically. In this report evidence is presented that schizophrenics differ widely on measures of electrodermal activity, heart rate, systolic blood pressure, and finger skin temperature. Two extreme physiological groups may be defined by the presence or absence of skin conductance orienting responses to tones of moderate intensity.
