Sensorimotor decisions are influenced by factors beyond the current sensory input, but little is known about the effect of preceding motor actions. Here, we show that choice-unrelated motor actions influence subsequent sensorimotor decisions. By instructing participants to perform choice-unrelated motor responses before visuomotor decisions, we could manipulate upcoming decisions in a directed fashion. Subjects tended not to repeat the instructed motor response. Our results show that simple motor behaviors can influence subsequent sensorimotor decision.
感觉运动决策受到当前感觉输入以外的因素的影响，但对于先前运动动作的影响知之甚少。在这里，我们表明与选择无关的运动动作会影响随后的感觉运动决策。通过指示参与者在进行视觉运动决策之前执行与选择无关的运动反应，我们可以以定向的方式操纵即将到来的决策。受试者往往不会重复所指示的运动反应。我们的结果表明，简单的运动行为可以影响随后的感觉运动决策。
