According to the ideomotor principle, action preparation involves the activation of associations between actions and their effects. However, there is only sparse research on the role of action effects in saccade control. Here, participants responded to lateralized auditory stimuli with spatially compatible saccades toward peripheral targets (e.g., a rhombus in the left hemifield and a square in the right hemifield). Prior to the imperative auditory stimulus (e.g., a left tone), an irrelevant central visual stimulus was presented that was congruent (e.g., a rhombus), incongruent (e.g., a square), or unrelated (e.g., a circle) to the peripheral saccade target (i.e., the visual effect of the saccade). Saccade targets were present throughout a trial (Experiment 1) or appeared after saccade initiation (Experiment 2). Results showed shorter response times and fewer errors in congruent (vs. incongruent) conditions, suggesting that associations between oculomotor actions and their visual effects play an important role in saccade control.
根据意念运动原理，动作准备涉及到动作与其效果之间的关联的激活。然而，关于动作效果在眼跳控制中的作用的研究还很稀少。在这里，参与者用与空间相容的眼跳对侧化的听觉刺激做出反应，朝向外周目标（例如，左半视野中的菱形和右半视野中的正方形）。在命令性听觉刺激（例如，左音）之前，呈现一个与外周眼跳目标（即眼跳的视觉效果）无关的中央视觉刺激，该刺激与外周眼跳目标一致（例如，菱形）、不一致（例如，正方形）或不相关（例如，圆形）。在整个试验中（实验 1）或在眼跳开始后（实验 2）呈现眼跳目标。结果表明，在一致条件下（与不一致条件相比），反应时间更短，错误更少，这表明眼动动作与其视觉效果之间的关联在眼跳控制中起着重要作用。
