Abstract
This study was designed to evaluate preference of the sensory stimulus of children with autism. 6 children participated in the experiments. Experiment 1 was designed to determine relative preference three different modes stimulating (visual, auditory, and tactile). Two button switches were settled in free operant situation and the subjects were permitted to choose each of them. After they pushed the button either two, one of the three stimuli was administered on them. Each of the stimuli was presented for 5 seconds, It was demonstrated that, for 4 out of 6 children, preference hierarchy was identified from establishing weak stochastic transitivity. Instead of single mode stimulus events, three combinations of stimuli (visual-auditory, auditorytactile, and tactile-visual) were used in Experiment 2. The result of Experiment 2 was compared with Experimentl's. It was shown that the preference of children with autism could be systematically assessed and analyzed. Furthermore, it would be suggested that the preference hierarchy of the combination of different modes of stimuli could be predicted from that of simple mode of stimulus,
