The encoding strategies to remember as many witnessed events as possible afterwards was discussed. Four types of encoding strategies, which were 1) to verbalize the events as fully as possible, 2) to fix their eyes intentionally on many points, 3) to elaborate the events, and 4) to memorize the scene as it is, were compared with each other, and were also compared with 5) the control group that subjects were told to memorize as much as possible. Subjects were presented with three portraits(Exp.1) or ten slides(Exp.2) as materials, and were to memorize them by one of the strategies mentioned above. As a result of memory tests for details of to-be-remembered materials. 1) the verbalization strategy group and 5) the control group performed significantly better than other three groups. There were no significant interactions between retention intervals and memorization stratedies. The results implies that intentional encoding strategies other than verbalization strategy impair the memory for remembering. The practical use on the actual criminal investigation was discussed on the basis of the results.
