运动策略进行了调查，在触觉搜索任务，参与者表示是否存在目标之间的不同数量的项目。根据两个标准将手部运动分为三种运动类型。结果表明，一个简单的搜索与并行策略进行，而在一个更困难的搜索串行运动策略使用。简单搜索中的动作简短而流畅，而困难搜索则显示出更详细的动作，并且当要搜索更多项目时，这一数量会增加。这些搜索任务之间的差异仍然校正旅行距离时，而路径长度可以部分解释与目标存在和不存在的试验之间的差异。总的来说，这些结果表明，运动策略主要是调整的搜索条件和目标的显着性，和目标的存在和设置大小。
Movement strategies were investigated in a haptic search task where participants indicated whether a target was present among a varying number of items. Hand movements were classified according to two criteria into three movement types. Results indicated that an easy search was performed with a parallel strategy, while in a more difficult search a serial movement strategy is used. Short, fluent movements were made in the easy search, whereas the difficult search showed more detailed movements and this amount increased when more items were to be searched. These differences between the search tasks remained when corrected for travelled distance, while path length could partly explain dissimilarities between trials with a target present and absent. Overall, these results indicate that movement strategies are adjusted primarily to the search condition and the salience of the target, and less to the presence of a target and set size.
