表象运动推断加工子系统特性的实验研究

AN EXPERIMENTAL STUDY OF THE PROPERTY OF THE PROCESSING SUBSYSTEM OF IMAGE - MOTION EXTRAPOLATION

通过检测20名飞行员和10名老年被试及其控制组的表象运动推断加工水平，结果表明：（1）除较易任务上的反应时与其控制组构成显著差异外，飞行员在表象运动推断的加工速度和正确方面均未表现出较大的优势；（2）与较易水平上的任务相比，老年组在较难水平上表象运动推断加工的速度和正确性方面均未同青年组构成显著差异；（3）与青年组被试相比，老年组在加工耗时量方面受加工量增大的影响较小，且在反应正确性方面与青年组粮比上下发现显著作的改变。研究结果提示，负责表象运动推断加工的子系统没有因系统的训练和年老化过程的影响而发生明显的功能改变，从而表现出了一种相对稳定的认知特性。

The processing level of image-motion extrapola-tion in twenty pilots and 10 elderly adults and theircontrol subjects were tested and analyzed. The resultsindicated: 1) Both the speed and accuracy of the image-motion extrapolation tasks in pilots were not signifi-cantly superior to those of the controls, except for theresponse time on the easy tasks, 2) Both the speedand accuracy in the more difficult tasks of the elderlyadults and controls did not differ significantly, andthere was less effect of processing amount on responsetime in the elderly adults than the controls. The re-sults implied that the processing subsystem of image-motion extrapolation possesed some cognitive stabili-ty.
