THE EFFECT OF AGE, DEGEES OF TASK DIFFICULTY AND TRAINING ON ADULT'S MEMORY
将成人分为青年、老年和高龄三组，通过联想学习和自由回忆测试，发现年龄越大记忆越差，任务越难年龄差异越大，训练能提升各年龄组记忆但会扩大年龄和难度差异。
adults were divided into three groups:young.old and aged.They were tested and trained through associative learning, figural free recall and additional association learning tests The purpose of this study was to investigate the effect of age, degrees of task difficulty and training on memory. The results indicated that: 1)the performances of the yeung group were significantly better than that of the two seniorgroups.There is no difference between the two senior groups. 2) The age difference of unrelated association is greater than that of related assecia tion.It is proportional to the degreesof task dif ficulty. 3) After training, the memory performa nces were improved in each age group. The age differences and the differences in degrees of task difficulty were increased by training. It showed that memory was affected by the interaction among age, degrees of task difficulty and train ing. The plasticity of cognitive function in the aged was also demonstrated.
