我们研究了128名日本大学生在5项典型神经心理运动任务（握力、手指敲击、两种版本的凹槽钉板和点状填充测试）中的手间差异得分，并检验了手偏好与运动熟练度的手间差异之间的关系。使用爱丁堡利手性量表，分别有18名和110名参与者被确定为左撇子和右撇子。尽管在所有五项任务中，惯用右手的参与者的右手比左手表现得更好，反之亦然，但不同任务之间的手间差异程度有所不同。以五个运动任务的横向商为自变量的判别函数分析表明，从任务表现可以预测手偏好，准确率为90%或更高。点位填充测验和手指敲击测验比其他任务具有更强的规范负荷。
We explored the intermanual difference scores of 128 Japanese university students for five typical neuropsychological motor tasks (grip strength, finger tapping, two versions of the grooved pegboard, and the dot‐filling test) and examined the relation between hand preference and intermanual difference in motor proficiency. Using the Edinburgh Handedness Inventory, 18 and 110 participants were identified as left‐ and right‐handed, respectively. Although the right hand performed better than the left for right‐handed participants, and vice versa, in all five tasks, the degree of intermanual difference varied between tasks. A discriminant function analysis using the laterality quotients of the five motor tasks as independent variables indicated that hand preference was predictable from the task performances with an accuracy of 90% or more. The dot‐filling test and finger tapping had stronger canonical loadings than the other tasks.
