Spatial distance of response keys has been shown to have an effect on nonspatial tasks in that performance improved if the spatial distance increased. Comparably, spatial distance of stimulus features has been shown to have a performance-improving effect in a (partly) spatial task. Here, we combined these two findings in the same task to test for the commonality of the effect of stimulus distance and the effect of response distance. Thus, we varied spatial distance in exactly the same fashion either between stimuli or between responses in a standard Eriksen flanker task. The results show that spatial distance only affected the processing of stimulus features, while it had no effect on the processing of response features. Regarding the idea of common coding of action and perception (Prinz, 1990), stimulus and response processing should be influenced by spatial distance in the same way so that our data might suggest a boundary for the idea of common coding.

响应键的空间距离已显示对非空间任务有影响，因为如果空间距离增加，性能会提高。相比之下，刺激特征的空间距离已显示出在（部分）空间任务中具有性能改善效果。在这里，我们将这两个发现结合在同一任务中，以测试刺激距离效应和响应距离效应的共性。因此，在标准Eriksen侧翼任务中，在刺激之间或在响应之间，我们以完全相同的方式改变空间距离。结果表明，空间距离仅影响刺激特征的处理，而对响应特征的处理没有影响。关于对行为和知觉进行通用编码的想法（Prinz，1990年），
