Tested rural Michigan black (N = 60) and white (N = 60) children of variant academic achievement on the Minnesota Percepto-Diagnostic Test for visual-motor skill development. The test, which consists of six gestalt designs for the person to copy, includes four measures of such skill development: Degree of copied design rotation and errors of separation of circle-diamond, distortion of circle-diamond and distortion of dots. In general, analyses that statistically controlled for intellectual level indicated that race was not a significant variable in the relationship of achievement level and visual-motor test performance. That is, such analyses resulted only in a significant achievement effect; low achievers, in comparison with high achievers, performed poorly on the copying test. Only with distortion of circle-diamond errors was a race interactive effect noted; i.e., black low achievers had significantly more errors than black high achievers, white low achievers or white high achievers. Results were discussed in relation to environmental determinants and symptomatology correlates.
对密歇根州农村地区学业成绩各异的60名黑人儿童和60名白人儿童进行了明尼苏达感知诊断测试，以评估其视觉运动技能发展情况。该测试包括六种格式塔设计供受试者临摹，涵盖了四项此类技能发展的测量指标：临摹设计的旋转程度、圆菱形分离错误、圆菱形变形以及点的变形。总体而言，在对智力水平进行统计控制的分析中，结果表明种族并非成绩水平与视觉运动测试表现之间关系的显著变量。也就是说，此类分析仅产生了显著的成绩效应；与高成就者相比，低成就者在临摹测试中的表现较差。仅在圆菱形变形错误方面发现了种族交互效应；即，黑人低成就者的错误显著多于黑人高成就者、白人低成就者或白人高成就者。研究结果结合环境决定因素和症状学相关性进行了讨论。
