 note = {An experiment was done with 12 persons with profound retardation in order to study expectancy with emotional expression to another person's appearance and acts. The experimenter showed his upper body through the window of the booth for 2 seconds following a chime sound (S1) and then hid his body for 3 seconds (S1-S2 interval). He then presented himself in front of the subjects from behind a screen while calling the subject's names (S2). Sixty trials in 3 days were carried out for each subject. By observation of emotinal behavior, subjects were divided into three groups based on the latency of laughing or smiling. Subjects of group a showed laughing and smiling prior to presentation of S2, and one of them showed anticipatory deceleration in HR changes. Subjects showing emotional expression after presentation of S2 (group β) showed continuous HR deceleration in S1-S2 interval. Those who expressed neither laughing nor smiling (group γ) showed orienting response to S1. The results indicated that laughing and smiling prior to person's acts were coincident with expectancy in person with profound retardation., 金沢大学教育学部障害児教育, 金沢大学教育学部理科教育},
