三维立方体测验的效标关联效度

Study on criterion-related validity of 3 dimensional cube test

目的 :通过比较不同空间能力个体三维立方体测验成绩 ,验证三维立方体测验的有效性并探讨言语能力对空间能力的影响 .方法 :采用认知分化成套测验和韦氏成人智力测验的言语测验对 82名健康男性大学生进行分组 ,比较各组三维立方体测验的成绩 ,对言语能力与空间能力进行相关分析 ,比较言语能力高、低各组空间能力的差异 .结果 :高空间能力组与低空间能力组在三维立方体旋转测验正确率 (CN)、平均反应时 (ART)和单位时间正确数 (CNPS)三项指标均存在显著性差异 ,高空间能力组明显优于低空间能力组 (P <0 .0 5 ) ;全部被试CLB空间能力成绩与CNPS显著相关 (r =- 0 .2 6 9,P =0 .0 1 5 ) ,高、低空间能力被试CLB空间能力成绩与CN (r=- 0 .30 8,P =0 .0 4 2 )、ART (r =0 .333,P =0 .0 2 7)、CNPS (r=- 0 .4 35 ,P =0 .0 0 3)均有显著相关 .言语能力与空间能力无相关 .结论 :三维立方体测验对不同空间能力个体有着较好的区分度 ,是空间能力视觉化成分测量的较好指标 ;在同一性别中 。

AIM: To explore verbal ability impact on spatial ability and testify the predictive validity of 3 dimensional cube test in the same sex by comparison of scores of 3 dimensional cube test between individuals of different spatial ability. METHODS: Eighty two healthy male college students were tested by cognitive laterality battery test, 3 dimensional cube test and WAIS C. RESULTS: Individuals of high and low spatial ability had significant difference in correct number (CN), average reaction times (ART) and in correct number per second (CNPS) ( P <0.05). CNPS had significant correlation with scores of spatial ability ( r =-0.269, P = 0.015). Within the groups of high and low spatial ability, scores of spatial ability had significant correlation with CN ( r =-0.308, P =0.042), ART ( r =0.333, P = 0.027), CNPS ( r =-0.435, P =0.003). Verbal ability, had no relation with spatial ability. CONCLUSION: Individuals of different spatial ability are obviously distinguished by 3 dimensional cube test which can be regarded as a good test when evaluating the component of visualization of spatial ability . The verbal ability has no effect on spatial ability in the same sex.
