【摘要】 采用“联想学习”、“图象自由回忆”和“附加联想”三项目，对９０例成人（分为青年、老年和老老年组各３０例）进行记忆测查和训练，目的为探讨年龄，作业难度和训练对记忆的影响。结果表明：青年组记忆成绩明显高于老年和老老年组，后两组无显著差异；无关联想的年龄差异大于有关联想，作业难度扩大了年龄差异；各年龄组训练后记忆得到明显改善，并且训练扩大了年龄和作业易难的差异。由此可见，记忆受年龄、作业难度和训练三因素的相互作用，也再次证实了老年认知功能具有一定的可塑性。更多还原

【Abstract】 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.更多还原
