反復音刺戟系列に於ける廳形態の形成と展開

副制作の研究 III

抄録

This investigation studies the effect of satiation when the subject is exposed to the repeated stimulation of a simple, monotonous sound a long time.
Six observers comprising four psychologists, one musician who is a composer as a conductor and the writer himself took part in this experiment. They were presented with metronome clicks repeated at the rate of 120 clicks per minute for a duration of about 30 minutes. They listened to these clicks with closed eyes and subsequently reported upon the total phenomena experienced during the sitting.
Results.
1. As the experiment went on, the following changes took place in various phases of the auditory Gestalts :
a. Changes in accent.
b. Changes in sound quailty.
c. Changes in grouping.
d. Changes in spatial localization.
2. In the succeeding stages, especially in the latter part of the experiment, at times the “figure” character of metronome sounds diminished spontaneously, while at other times the endeavour to suppress the appearance of “figure” character was evident in the observers' reports.
3. As the metronome clicks took the character of the “ground”, the other sensory experiences such as organic sensation and nises other than the clicks themselves took the “figure” character and finally the perceiving activity of the observers passed into the image-forming activity.
4. The musician and the writer were led into the formation of musical images while the other observers were engaged in day-dreams whose contents were mostly of the ego-involved daily happenings.
