発話傾向についての自己報告に基づく個人の分類 A CLASSIFICATION OF TYPES OF SUBJECTS BASED ON SELF-REPORTS ON A TENDENCY TOWARD SPEECH
The purpose of this study was to classify types of subjects based on self-reports on a tendency toward speech; i.e., tendency toward social or private speech in everyday life. Two hundred and thirty subjects responded to a questionnaire made of 24 items. Two factors, i.e., "social speech tendency" and "private speech tendency" factors, were confirmed by factor analysis. Additionally, subjects were classified by cluster analysis based on factor scores of 2 factors, and several types were hierarchically abstracted. In the upper level, 2 clusters: "high speech type" and "low speech type", were abstracted. In the lower level, 4 clusters: "low social speech and high private speech type", "high speech tendency type", "high social speech and low private speech type", and "low speech tendency type", were abstracted.
