儿童、中青年及老年人心理旋转能力的比较研究

采用12套不同视觉形状图形，探讨了儿童(7—9岁，均龄8岁)、中青年(23—47岁，均龄31．3岁)及老年人(61—79岁，均龄65．6岁)的心理旋转能力。结果表明不同年龄段被试的心理旋转能力存在明显差异。无论是对图形方位匹配判断的准确性还是完成判断任务的速度，中青年组被试的成绩均明显优于其他两组被试。儿童组被试在完成判断的速度上明显优于老年组，但在准确性方面两者不存在明显差异。各个年龄组的成绩均不存在性别差异。

A Comparative Research on the Mental Rotation of Children,Young-Middle-Aged people and Aged People

This study investigated the mental rotation of Chinese children,young-middle-aged people and old people. 66 subjects were divided into three groups according to their age: children group (7-9 yrs, average aged 8), young-middle-aged group (23-47 yrs, average age 31.3 ), old age group ( 61-79 yrs, average age 65.6 ). 12 sets of visual figures with different shapes were used as experimental samples in this study. Each set included five similar figures. The subject was asked to find out among the five figures the one which could not be matched with the others in the spatial position. The results showed that the accuracy and matching speed in the figure matching of the young and middle-aged people were much better than those of the children and old aged. It was found that the matching speed in children was faster than that of the old, but there was no obvious difference in the accuracy level. There were no significant differences between males and females in their performance.
