Nonparallel relationship between tolerance and sensitivity for visual and aditory environmental stimuli

Abstract

In this paper, the four types which concern the relationship between sensory tolerance and sensiveness for environmental sensory stimuli were proposed theoretically. These hypothetical four types were supported by the results obtained from factor analytical approach. The two checklists were compiled in place of actual psycho-physical measurements in order to apply the factor analysis. The first version of the checklist was applied to the 100 male subjects, and the second version to the 229 male subjects. The eight factors which resulted from the first version of the list were the following: A) General sensitivity, B) Temporal sensitivity, C) Orientation to the strong and prolonged sensory (the two factors were included in this label), D) Orientation to the weak stimuli (the two factors were included also), E) Activation level, F) Abnormal temporal sensitivity. The six factors were obtained from the second version of the list. Five factors of these six, s were the same as to each of above mentioned A to E. The other one was G) Sensory-motor reactivity. The four factors, A to D, which resulted from two large sample of the subjects, and from the different checklists, were the sensory properties common to inter-moeal senses. The factors A and B related to “the culture free behavior”, and the factor C and D related to “the culture bound behavior”. These four factors gave support to the existence of the four types.
