执行一个自愿的行动涉及预期的效果，该行动。与环境的互动也需要注意力的分配。然而，注意对运动预测过程的影响仍然不清楚。在这里，我们使用一种新的范式来研究注意和运动预测正交。在采集阶段，高和低音调与左和右按键相关联。在接下来的测试阶段中，音调是随机呈现的，参与者只注意一只耳朵，而忽略了在无人注意的耳朵中呈现的音调。因此，在测试阶段，一个音调可以出现在有人或无人的耳朵上，也可以与先前的动作效果学习一致或不一致。我们证明了早期和晚期的影响，以及后来的独立运动预测效果与较大的P3a不一致的音调。有趣的是，我们展示了一个中间的相互作用，表现出一个动作效果负（NAE）的音调是无人值守的，而没有运动预测效果被发现出席的音调。这种互动模式表明，注意力和运动预测不是对立的过程，但都可以操作，以调节预测，提供有价值的新的见解注意力和运动预测的影响之间的关系。
Performing a voluntary action involves the anticipation of the intended effect of that action. Interaction with the environment also requires the allocation of attention. However, the effects of attention upon motor predictive processes remain unclear. Here we use a novel paradigm to investigate attention and motor prediction orthogonally. In an acquisition phase, high and low tones were associated with left and right key presses. In the following test phase, tones were presented at random and participants attended to only one ear whilst ignoring tones presented in the unattended ear. In the test phase a tone could therefore be presented at the attended or unattended ear, as well as being congruent or incongruent with prior action–effect learning. We demonstrated early and late effects of attention as well as a later independent motor prediction effect with a larger P3a for incongruent tones. Interestingly, we demonstrated an intermediate interaction, showing an action–effect negativity (NAE) for tones which were unattended, whilst no motor prediction effect was found for attended tones. This interaction pattern suggests that attention and motor prediction are not opposing processes but can both operate to modulate prediction, providing valuable new insight into the relationship between attention and the effects of motor prediction.
