The present study describes a developmental performance measure of hand preference that considers task complexity and position in hemispace. Eighty right-handed children and adults (ages 3-4, 6-7, 9-10, 18-24) were observed for hand selection responses to 2 unimanual tasks (simple vs complex) across positions in hemispace. Results revealed an age-related trend in the tendency to use the preferred hand in right and left hemispace. While the adult's and 3- to 4-year-old's preferred hand use decreased as they moved into left hemispace, children between the ages of 6 and 10 years tended to use their preferred hands consistently throughout both regions of hemispace. The relationship between hand preference and skilled, cost-efficient performance throughout development are discussed.
本研究描述了一种手部偏好的发育表现测量方法，该方法考虑了任务复杂性和半空间位置。观察了80名右利手儿童和成人（年龄分别为3 - 4岁、6 - 7岁、9 - 10岁、18 - 24岁）对2项单手任务（简单任务与复杂任务）在半空间不同位置的手部选择反应。结果显示，在右半空间和左半空间使用优势手的倾向存在与年龄相关的趋势。虽然成年人和3至4岁儿童在进入左半空间时优势手的使用减少，但6至10岁的儿童在整个半空间区域往往持续使用他们的优势手。文中还讨论了在整个发育过程中手部偏好与熟练、高效表现之间的关系。
