越来越多的证据表明，即使在没有任何明确的行动准备的情况下，行动的约束也会影响目标选择的早期阶段。在这里，我们研究了图像的动作属性是否会影响视觉搜索，以及这种影响是否会受到手偏好的调节。观察者在三个干扰物中寻找一个古怪的目标。搜索数组包括可抓取的“手柄”（“与动作相关”的刺激）的图像，或者与手柄相同的图像，但其中半圆支点元素被重新定向，使刺激不再看起来像可抓取的物体（“与动作无关”的刺激）。在实验1中，惯用右手的观察者在完成手工任务时更喜欢使用右手而不是左手，他们在动作相关的数组中比非动作相关的数组中更快地检测到目标，并且在向右的动作相关手柄比向左的动作相关手柄上表现出反应时间（RT）优势。在实验2中，左撇子观察者在手工任务中使用左手和右手的频率相对相同，他们在动作相关和非动作相关的数组中检测目标的速度也更快，但RTs对向右和向左的手柄目标的检测速度是一样的。综上所述，这些结果表明，图像中的动作属性，以及由手动与物体交互的偏好所施加的动作约束，可以影响视觉搜索背景下的注意力选择。
There is mounting evidence that constraints from action can influence the early stages of object selection, even in the absence of any explicit preparation for action. Here, we examined whether action properties of images can influence visual search, and whether such effects were modulated by hand preference. Observers searched for an oddball target among three distractors. The search arrays consisted either of images of graspable ‘handles’ (‘action-related’ stimuli), or images that were otherwise identical to the handles but in which the semicircular fulcrum element was re-oriented so that the stimuli no longer looked like graspable objects (‘non-action-related’ stimuli). In Experiment 1, right-handed observers, who have been shown previously to prefer to use the right hand over the left for manual tasks, were faster to detect targets in action-related versus non-action-related arrays, and showed a response time (RT) advantage for rightward- versus leftward-oriented action-related handles. In Experiment 2, left-handed observers, who have been shown to use the left and right hands relatively equally in manual tasks, were also faster to detect targets in the action-related versus non-action-related arrays, but RTs were equally fast for rightward- and leftward-oriented handle targets. Together, or results suggest that action properties in images, and constraints for action imposed by preferences for manual interaction with objects, can influence attentional selection in the context of visual search.
