In action-control research, typically, stimulus sparse displays are used. This might be one reason why previous theorizing focuses on the (top-down) demands of response selection (e.g., what key to press), while often ignoring (bottom-up) demands of stimulus selection (e.g., what stimulus to attend). However, complex perceptual situations may pose selection demands that make additional, response-unrelated feature dimensions relevant for response selection. The major stimulus characteristic affecting perceptual selection is salience. In research on visual attention, there is a debate about the conditions under which salience becomes effective. We related both debates in two experiments, in which we modulated display set size as well as salience in a stimulus-response binding task. In sum, the data of these experiments (pooled N = 138) demonstrated that salience furthered the integration of stimulus features in displays with many stimuli more than in sparse displays. Our results demonstrate the neglected impact of salience on action-control when going beyond the very simplistic displays common in action-control research.

在动作控制研究中，通常使用刺激稀疏显示。这可能是之前的理论研究集中于（自上而下）的反应选择需求（例如，按哪个键），而经常忽略（自下而上）的刺激选择需求（例如，注意哪个刺激）的原因之一。然而，复杂的感知情况可能会产生选择需求，使额外的、与反应无关的特征维度与反应选择相关。影响感知选择的主要刺激特征是显著性。在视觉注意力研究中，关于显著性何时变得有效的争论一直存在。我们在两个实验中把这两个争论联系起来，在这两个实验中，我们在刺激-反应绑定任务中调节了显示集的大小和显著性。总的来说，这些实验的数据（合并 N=138）表明，在具有许多刺激的稀疏显示中，显著性比在稀疏显示中更能促进刺激特征的整合。我们的结果表明，当超越动作控制研究中常见的非常简单的显示时，显著性对动作控制的影响被忽视了。
