Changes in patterns of hand use were examined as a function of task demand characteristics. Using blocks, right- and left-handed male and female subjects were asked to simultaneously construct two replicas of presented patterns, one with each hand. With the presentation of visual-spatial patterns, a shift toward use of the left hand from baseline was observed. This change was least evident among right-handed females. The observed shift in hand use toward the left on a visuo-constructive block design task might suggest differential involvement of the right hemisphere with changes in task demand characteristics.
根据任务需求特征，对手部使用模式的变化进行了研究。使用积木，要求右利手和左利手的男性和女性受试者同时用每只手构建两个呈现图案的复制品。随着视觉空间图案的呈现，观察到与基线相比左手使用频率增加。这种变化在右利手女性中最不明显。在视觉建构积木设计任务中观察到的手部使用向左侧的变化可能表明右半球在任务需求特征变化时的参与程度不同。
