在日常生活中,认知和行动常常是交织在一起的。因此,理解认知过程如何与并发行为一起运作是至关重要的。本研究的目的是评估简单的体力劳动如何运作为等长肌肉收缩影响视觉注意和抑制控制。在双任务范式中,参与者同时执行单一搜索任务和握握任务。在搜索任务中,目标在形状相同但形状不同的干扰物中是形状单一的。在一半的实验中出现了一个具有独特颜色的显著但不相关的干扰物(即颜色单一)(单一干扰物存在条件),并且它的存在经常捕获空间注意力。关键的是,视觉搜索任务是由参与者在手测力计上以最大强度的5%或40%(低与高物理负荷)同时握力进行的。我们发现,在体力劳动下的视觉搜索速度更快,但更容易受到干扰,这可能分别是由于觉醒和抑制控制的减少。这两种效应进一步体现在RT分布的不同方面,可以通过使用分层贝叶斯方法的前高斯模型的不同组成部分来捕获。总之,这些结果为两种可分离的认知机制提供了行为证据和一个新的模型,这些机制是基于简单的肌肉运动对正在进行的视觉搜索过程的影响。
Cognition and action are often intertwined in everyday life. It is thus pivotal to understand how cognitive processes operate with concurrent actions. The present study aims to assess how simple physical effort operationalized as isometric muscle contractions affects visual attention and inhibitory control. In a dual-task paradigm, participants performed a singleton search task and a handgrip task concurrently. In the search task, the target was a shape singleton among distractors with a homogeneous but different shape. A salient-but-irrelevant distractor with a unique color (i.e., color singleton) appeared on half of the trials (Singleton distractor present condition), and its presence often captures spatial attention. Critically, the visual search task was performed by the participants with concurrent hand grip exertion, at 5% or 40% of their maximum strength (low vs. high physical load), on a hand dynamometer. We found that visual search under physical effort is faster, but more vulnerable to distractor interference, potentially due to arousal and reduced inhibitory control, respectively. The two effects further manifest in different aspects of RT distributions that can be captured by different components of the ex-Gaussian model using hierarchical Bayesian method. Together, these results provide behavioral evidence and a novel model for two dissociable cognitive mechanisms underlying the effects of simple muscle exertion on the ongoing visual search process on a moment-by-moment basis.
