不同空间能力个体二维心理旋转测验比较研究

Comparison of Two-dimensional Mental Rotation Test in Different Individual Spatial Ability

目的通过比较不同空间能力个体二维旋转图形测验成绩验证二维心理旋转测验的效标关联效度。方法将某军校88名健康男性学员进行认知分化成套测验,选择测验成绩好的24名设为高空间能力组(n=24),成绩差的24名设为低空间能力组,比较两组二维旋转图形测验成绩。结果与低空间能力组比较,高空间能力组二维旋转图形测验单位时间正确数高、平均反应时间快,差异有统计学意义(P<0.01);两组言语智商差异无统计学意义(P>0.05)。结论二维旋转图形测验对不同空间能力个体有着较好的预测效度,是空间能力测量的较好指标。

Objective To validate the criterion-related validity of two-dimensional mental rotation test,using comparison of scores of two-dimensional mental rotation test in different individual spatial ability. Methods A total of 88 healthy male students in military academies received cognitive laterality battery test,and 24 students with high scores were chosen as high spatial ability group,while 24 students with low scores were chosen as low spatial ability group,and then the two-dimensional mental rotation test results of two groups were compared. Results Compared with those in low spatial ability group,the individuals in high-spatial ability group had higher score in correct number per second and quicker average reaction times,and the differences were statistically significant（ P〈0. 01）; there was no statistical significance in verbal intelligence quotient（ IQ） in the two groups（ P〉 0. 05）. Conclusion Two-dimensional mental rotation test has good criterion-related validity for different spatial ability of individual persons,so it may be regarded as a good test for detecting the spatial ability.
