具有巨大社会相关性的刺激会从外部吸引注意力。在这里，我们探讨了身体相关的刺激对内源性注意的影响。此外，我们调查的内部状态对偏向注意这类刺激的影响。参与者提出了一个身体，脸，或椅子提示举行记忆（记忆任务）或只是出席（启动任务），随后，他们被要求找到一个圆圈在一个不相关的视觉搜索任务。在有效条件下，圆圈的两侧是线索。在无效条件下，预先提示的图片重新出现在干扰物的侧面。在中性条件下，提示项不会重新出现在搜索显示中。我们发现，虽然身体和面孔的视觉处理速度比坐在椅子上更快，但与仅仅关注它们时相比，将它们放在记忆中并没有产生任何额外的注意力优势。此外，在记忆和启动任务中，与身体和椅子线索相比，面孔线索产生了更大的定向效应。重要的是，研究结果表明，个体对内部身体反应的敏感性预测了基于记忆的身体注意力定向的大小，为身体意识和视觉空间注意力之间的关系提供了新的线索。
Stimuli of great social relevance exogenously capture attention. Here we explored the impact of body-related stimuli on endogenous attention. Additionally, we investigate the influence of internal states on biased attention towards this class of stimuli. Participants were presented with a body, face, or chair cue to hold in memory (Memory task) or to merely attend (Priming task) and, subsequently, they were asked to find a circle in an unrelated visual search task. In the valid condition, the circle was flanked by the cue. In the invalid condition, the pre-cued picture re-appeared flanking the distracter. In the neutral condition, the cue item did not re-appear in the search display. We found that although bodies and faces benefited from a general faster visual processing compared to chairs, holding them in memory did not produce any additional advantage on attention compared to when they are merely attended. Furthermore, face cues generated larger orienting effect compared to body and chairs cues in both Memory and Priming task. Importantly, results showed that individual sensitivity to internal bodily responses predicted the magnitude of the memory-based orienting of attention to bodies, shedding new light on the relationship between body awareness and visuo-spatial attention.
