【摘要】 以高水平视觉加工理论为基础,采用斯腾伯格加因素法作为评定加工效能的研究范式,检测了10名老年被试及其控制组的表象运动推断加工水平。研究结果表明,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;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相比也未发现显著性的改变。负责表象运动推断加工的子系统没有因年老化过程而出现功能上的明显改变,从而表现出一种相对稳定的神经认知特性。更多还原

【Abstract】 To examine the neurocognitive characters of image_motion extrapolation processing in aging, based on the high_level visual processing model. Processing level of image_motion extrapolation in 10 elderly adults and 10 control subjects were tested with Sternberg’s additive factors paradigm for assessing the efficacy of process in this cognitive task. Compared with easy level in this task, both speed and accuracy of processing in the more difficult task in elderly adults were not significantly inferior to that of controls; There was smaller effect of processing amount on response time in elderly adults than controls, and accuracy on this task in elderly and controls differed significantly. Due to the fact that processing level of image_motion extrapolating subsystem did not significantly decrease with aging, the process of image_motion extrapolation showed relatively a property of neurocognitive stability. 更多还原
