短期記憶の連続時間モデルに基づく文字提示時間の最適配分(一般講演-感性・記憶・知的システム-)

抄録

In this paper, using the time- continuous model of short- term memory, we have studied the optimum-apportionment modes of the presentation time of eight randomly-selected alphabet letters sequentially presented in the same position on a CRT display unit screen visually and through a headphone acoustically to four young males. These modes are thought to allow for the easiest retention by the short- term memory. These modes have shown the same tendency as those in a visual display or in an auditory display. Individual differences appear in the middle part. There are two cases in this part of the optimum-apportionment mode : in the first case, the presentation time of one alphabet letter is longer than that of previous alphabet letter and the following alphabet letter. In the other case.the presentation time of the alphabet letters decreases monotonically according to its serial position. The number of recalled alphabet letters with the optimum-apportionment mode is larger than that in the visual display or in the auditory display for all subjects.
