Recent studies have shown that spatial and feature-based attention can contribute to inducing a spatial compatibility effect in both the standard Simon task and the joint Simon task. Less work generally has been devoted to investigating how attention modulates spatial compatibility effects. In the present study, we aimed to explore whether indirectly manipulating the degree of attention necessary to respond to a compatible or an incompatible stimulus can modulate the spatial compatibility effect in a joint Simon task and elicit a compatibility effect in the individual go-no-go Simon task. To this end, we biased spatial attention to the compatible stimulus by asking participants to perform a pointing response always toward the compatible side, regardless of the stimulus location. Crucially, reaction times-recorded at gesture onset-showed a compatibility effect pattern in the individual condition and an additional modulation in the joint condition. These results show that the spatial attention intrinsic to action planning can affect both individual and joint Simon tasks.
最近的研究表明，基于空间和特征的注意力能够在标准西蒙任务和联合西蒙任务中促成空间兼容性效应。总体而言，较少有研究致力于探究注意力如何调节空间兼容性效应。在本研究中，我们旨在探讨间接操纵对兼容或不兼容刺激做出反应所需的注意力程度，是否能够调节联合西蒙任务中的空间兼容性效应，并在个体简单反应西蒙任务中引发兼容性效应。为此，我们通过要求参与者无论刺激位置如何，始终朝着兼容侧进行指向反应，从而使空间注意力偏向兼容刺激。至关重要的是，在手势开始时记录的反应时间在个体条件下呈现出兼容性效应模式，在联合条件下则出现了额外的调节。这些结果表明，动作规划中固有的空间注意力会影响个体和联合西蒙任务。
