Action control is hierarchically organized. Multiple consecutive responses can be integrated into an event representation of higher order and can retrieve each other upon repetition, resulting in so-called response-response binding effects. Previous research indicates that the spatial separation of responses can affect how easily they can be cognitively separated. In this study, we introduced a barrier between the responding hands to investigate whether the spatial separation of two responses also influences response-response binding effects. In line with previous research on stimulus-response binding, we expected an increased separability of responses to result in stronger response-response binding effects when responding hands were separated by a barrier. We indeed found stronger response-response binding effects with separated hands. Results indicate that a more distinct representation of individual actions through increased separability might benefit the control of hierarchical actions.
动作控制是分层组织的。多个连续的反应可以整合到更高阶的事件表示中，并在重复时相互检索，从而产生所谓的反应-反应绑定效应。先前的研究表明，反应之间的空间分离会影响它们在认知上的分离程度。在这项研究中，我们在反应手之间引入了一个障碍物，以研究两个反应之间的空间分离是否也会影响反应-反应绑定效应。与刺激-反应绑定的先前研究一致，我们预计当反应手被障碍物隔开时，反应的可分离性增加会导致更强的反应-反应绑定效应。我们确实发现了分离手时更强的反应-反应绑定效应。结果表明，通过增加可分离性来更清晰地表示单个动作可能有利于分层动作的控制。
