Postural changes and the maintenance of postural stability have been shown to affect many aspects of cognition. Here we examined the extent to which selective visual attention may differ between standing and seated postures in three tasks: the Stroop color-word task, a task-switching paradigm, and visual search. We found reduced Stroop interference, a reduction in switch costs, and slower search rates in the visual search task when participants stood compared to when they sat while performing the tasks. The results suggest that the postural demands associated with standing enhance cognitive control, revealing broad connections between body posture and cognitive mechanisms.
姿势变化和姿势稳定性的维持已被证明会影响认知的许多方面。在此,我们研究了在三项任务中,站立和坐姿时选择性视觉注意力的差异程度:斯特鲁普颜色词任务、任务转换范式和视觉搜索。我们发现,与坐着执行任务相比,参与者站立时执行斯特鲁普任务的干扰减少、任务转换成本降低,且视觉搜索任务的搜索速度减慢。结果表明,与站立相关的姿势需求增强了认知控制,揭示了身体姿势与认知机制之间的广泛联系。
