眼睛和手的运动都被证明会选择性地干扰视觉工作记忆。我们调查的工作记忆的背景下，同时眼-手运动，以接近的问题是否独立的眼睛和手的运动系统与视觉工作记忆相互作用。参与者记住几个位置，并在维护间隔期间进行眼睛，手，或同时眼手运动。随后，我们在眼睛或手部运动目标以及与动作无关的位置测试了空间工作记忆。我们发现，对于单眼和单手运动，与动作无关的位置相比，眼睛或手目标的记忆得到了显着改善。值得注意的是，当眼睛和手的动作同时准备，但在不同的位置，在两个运动目标的记忆增强，而没有两个独立的行动目标之间的权衡。这表明，眼睛和手的运动独立地增强视觉工作记忆在他们的目标位置，导致整体工作记忆的表现是高于预期时，招募只有一个效应。
Both eye and hand movements have been shown to selectively interfere with visual working memory. We investigated working memory in the context of simultaneous eye-hand movements to approach the question whether the eye and the hand movement systems independently interact with visual working memory. Participants memorized several locations and performed eye, hand, or simultaneous eye-hand movements during the maintenance interval. Subsequently, we tested spatial working memory at the eye or the hand motor goal, and at action-irrelevant locations. We found that for single eye and single hand movements, memory at the eye or hand target was significantly improved compared to action-irrelevant locations. Remarkably, when an eye and a hand movement were prepared in parallel, but to distinct locations, memory at both motor targets was enhanced—with no tradeoff between the two separate action goals. This suggests that eye and hand movements independently enhance visual working memory at their goal locations, resulting in an overall working memory performance that is higher than that expected when recruiting only one effector.
