Neuropsychological study for soatial memory and imagery function inaged people

为了研究老年人的记忆机制，我们进行了两个实验。以正常老年人、老年痴呆患者、正常青年（大学生）为实验对象。在一个实验中，无意义的假名单词和随机的几何图形被依次呈现，被试被要求判断所呈现的刺激是否以前出现过。结果表明，老年被试在单词和形状的分离上仅在单词刺激条件下表现较差。老年痴呆和年轻人没有这种分离。在另一项实验中，三组受试者被给予相同类型的人脸照片记忆任务。老年人对年轻人的照片表现出更好的表现。基于这些发现，强调了额叶功能在记忆功能随着年龄的增长而退化中的重要性。参考前人关于老年人记忆功能的神经心理学模型，对两个实验的结果进行讨论，并撰写最终报告。

To exammine the memory mechanisms in the aged people, two experiments were conduced. Normal aged people, senile dementia patients, and normal young adults (college students) participated in these experriments as subjects. In one experiment, nonsensa Kana words and random geometric shapes were presented sequentially and subjects were asked to decide if the presented stimulus was has appeared before or not. The results showed the dissociation between words and shapes, Aged subjects was inferior only in words stimulus condition. Senile dementia and young adults showed no such dissociation. In the other experiment, three groups of subjects were given same type of memory task with human face photographs. Aged people showd better perfomance with the photographs of young adults. Based upon these findings, the imortance of the frontal lobe function was stressed in the deterioration of memory function with aging.Consulting to previous neuropsychological models of memory function of the aged people, the results of the two experiments were discussed and the final report was prepared.
