The Effect of Various Modes of Rehearsal on Short-Term Recall

摘要

As part of a program of study directed to improving humandata reception, processing and storage, this activity sponsored experimental research to investigate three variables: the strategies employed by human subjects; the organization of the information being communicated; and the characteristics of the display itself. This report deals with the human operation of rehearsing briefly-perceived alpha-numeric material. The results support the conclusion that, under certain conditions of task stress, appropriate rehearsal can improve that human performance which is a function of shortterm memory and, thus, in a man-machine relationship, improve system performance. Suggested examples are given of the application of the findings within a military context, e.g., radar-scope monitoring within a Combat Information Center (CIC).
