目的：探讨表象旋转加工子系统中的年老认知特点。方法：采用Ｓｔｅｒｎｂｅｒｇ加因素法，检测１０名老年人和１０名青年人对表象旋转的加工水平，分析与表象旋转有关加工子系统特点。结果：老年组被试在表象旋转加工的正确性和反应时方面均显著低于控制组；与形状识别和确认两个加工系统相比，表象转换子系统受老年过程的影响较大，表现在旋转速度随年老过程而显著地降低。结论：表象旋转中各加工子系统具有不同的年老敏感性。
Objective: To investigate the characteristics of aged cognition in the surface rotation processing subsystem. Methods: The Sternberg plus factor method was used to detect the processing level of the imagery rotation in 10 seniors and 10 young people. The characteristics of processing subsystems related to appearance rotation were analyzed. Results: Compared with the control group, the correctness of the rotation processing and the response time of the aged group were significantly lower than those of the control group. Compared with the shape recognition and the confirmation of two processing systems, the image conversion subsystem was greatly influenced by the aging process, Rotational speed significantly decreases with age. Conclusion: Each processing subsystem in representation rotation has different age-sensitivity.
