本研究通过四个实验来确定在准备双指甲到达动作时观察到的干扰轨迹。目标位置由颜色指定，右手和左手目标可以是相同的颜色，也可以是不同的颜色。不同幅度(实验1)或不同方向(实验2)对同一颜色的目标发起的动作比对不同颜色的目标的对称动作更快。这些结果表明，在双手运动中观察到的成本出现在目标选择期间，而不是在运动编程期间。实验3和实验4进一步考察了与目标选择相关的干扰。当目标被呈现在与另一只手的反应相关的分心物中时，单手动作的反应时间成本被发现。在双手接触过程中观察到的干扰似乎反映了分离分配给每只手的反应规则的困难。(心理信息数据库记录(C)2016 APA，保留所有权利)
Four experiments were conducted to identify the locus of interference observed during the preparation of bimanual reaching movements. Target locations were specified by color, and the right-hand and left-hand targets could be either the same or a different color. Movements of different amplitudes (Experiment 1) or different directions (Experiment 2) to targets of the same color were initiated more quickly than symmetric movements to targets of different colors. These results indicate that costs observed during bimanual movements arise during target selection rather than during motor programming. Experiments 3 and 4 further examined the interference associated with target selection. Reaction time costs were found with unimanual movements when the target was presented among distractors associated with responses for the other hand. Interference observed during bimanual reaching appears to reflect difficulty in segregating the response rules assigned to each hand.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
