It is regrettable that many Japanese works in verbal learning and memory have been almost unknown to American and European psychologists because of the language barrier. Since the Japanese Journal of Psychology was published in 1927, more than two hundred experiments have been done in this field. Although the number of papers is not so great as those in the field of perception as reviewed by Prof. Akishige (3) in this journal, many unique and interesting studies have appeared. While it was impossible to criticize all the data in this short paper, the author has attempted to review only those works dealing with several typical problems, such as retroactive inhibition, transfer, change of trace, incidental learning, spread of effect and paired associates learning. Of course there are many other studies working on the problems of developmental factors, association, semantics, problem solving, resumption of interrupted tasks and so on. The author hopes that those studies will be reviewed by someone at an early day.
