摘　　要：本研究通过两个实验分别检测 2 0名飞行员和 10名老年被试及其相应控制组的表象扫描加工水平 ,旨在探讨表象扫描这一典型视觉空间认知加工所表现出的可塑性水平。研究结果表明 ,表象扫描加工水平既没有因外界系统的训练而发生功能增强的练习效应 ,也未出现随年老化过程所表现出的功能显著下降的年龄效应。研究提示 ,由于受大脑神经细胞活动特性改变的影响 ,表象扫描加工能力更多地表现出了其认知加工的相对稳定性或可塑性较低的认知特性。The study tried to examine the cognitive plasticity in the visual imagery scanning process. Two experiments were conducted to test the processing level of imagery scanning respectively in twenty pilots, ten elderly adults and their corresponding controls. The results indicated that neither the effect of practice nor the effect of age was found in the two experiments.The study suggested that influenced by some hereditary and intrinsic attributes of the cerebral nervous anatomic structure, the processing system of visual imagery scanning showed a relatively low cognitive plasticity and susceptibility. The implication was further discussed in terms of the high level visual processing theory and practical significance.
