许多运动技能需要快速选择运动目标并准备实现该目标的运动，例如在环境经常变化很快并且可以采取多种行动的运动中。人类可以从学习预测运动要求的感知线索中受益，从而可以更早地选择运动目标和运动准备。然而，如何学习这些感知线索仍然存在不确定性。在这里，我们研究这些知觉-运动关联的使用和学习。首先，我们询问关联的情景记忆是否可以支持学习。在实验 1 中，参与者首先记住符号和运动目标之间的关联。当这些符号随后作为提示出现时，到达动作的准备就像预览目标本身一样有效，而不需要额外的练习。接下来，我们询问是否可以使用统计学习来学习关联。在实验 2 中，参与者必须在运动任务本身期间学习关联。这种学习使得有效的动作准备成为可能，并且改进的速度随着关联的数量和复杂性而变化。这些发现表明，通过统计学习和记忆回忆的感知线索可以促进运动准备，强调了传统上不涉及运动行为的学习和记忆系统的潜在作用。
Many motor skills require rapidly choosing a movement goal and preparing a movement to that goal, such as in sports where circumstances often change quickly and many actions are possible. Humans can benefit from learning the perceptual cues that predict the requirements of movement so that the choice of a movement goal and movement preparation can occur earlier. However, there remains uncertainty about how these perceptual cues are learned. Here we investigate the use and learning of these perceptual-motor associations. First, we ask if episodic memory for associations can support learning. In Experiment 1, participants first memorized associations between symbols and movement goals. When these symbols were subsequently presented as cues, reaching movements were prepared as efficiently as if the goals themselves were previewed, without the need for additional practice. Next, we ask whether statistical learning can be used to learn the associations. In Experiment 2, participants had to learn the associations during the movement task itself. This learning enabled efficient movement preparation, and the rate of improvement scaled with the number and complexity of associations. These findings suggest that movement preparation can be facilitated by perceptual cues via statistical learning and memory recall, highlighting a potential role for learning and memory systems not conventionally implicated in motor behavior.
