This experiment examined the use of attentional stimuli for reaching in hemispace by strong right-dominant adults and children. Driving the hypothesis was the notion that developmental factors associated with use of attentional information may affect the programming of reaching movements in hemispace. Although the general pattern of responses was similar for both samples, children did not use attentional cues to program reaching movements in contralateral hemispace as effectively as adults. This result suggests that motor dominance and perhaps other factors were pivotal in motor programming for children. One possible explanation for the general behavior observed underlies an attentional hemispheric bias for a tendency to use the hand that is on the same side as the stimulus.
本实验研究了强右利手的成年人和儿童在半侧空间中利用注意力刺激进行伸手动作的情况。驱动该假设的观点是，与注意力信息使用相关的发育因素可能会影响半侧空间中伸手动作的编程。尽管两个样本的总体反应模式相似，但儿童在对侧半侧空间中利用注意力线索来编程伸手动作的效果不如成年人。这一结果表明，运动优势以及可能的其他因素在儿童的运动编程中起着关键作用。对所观察到的一般行为的一种可能解释是，存在一种注意力半球偏向，即倾向于使用与刺激在同一侧的手。
