Abstract

Faces and body parts play a crucial role in human social communication. Numerous studies emphasize their significance as sociobiological stimuli in daily interactions. Two experiments were conducted to examine the following: (a) whether faces or body parts are processed more quickly than other visual objects when relevant to the task and serving as targets, and (b) the effects of presenting faces or body parts as distractors on task reaction times and error rates. The first experiment focused on either faces or body parts, with five different visual objects. The second experiment examined effector body parts (e.g., hands) and core body parts (e.g., the torso), paired with the same visual objects. Thirty-six participants took part in the study, equally divided between Experiment 1 (N = 18) and Experiment 2 (N = 18). Participants were instructed to find if a target item, indicated by a green placeholder, matched a previously presented word cue, while they were instructed to keep ignoring the singleton object that was surrounded by the red placeholder. The results indicated that participants responded more quickly when finding faces but not body parts in Experiment 1. No such advantage was seen in Experiment 2 for either effector or core body parts compared to other objects. Interestingly, when faces were presented as distractors as a singleton, reaction times increased (Experiment 1), indicating that faces capture attention. This effect was not observed for effector or core body parts (Experiment 2). These findings suggest that faces capture attention more effectively than body parts.

从面孔到手指:利用色彩单子范式研究人脸和身体部位的注意力捕捉。
面孔和身体部位在人类社会交流中起着至关重要的作用。许多研究都强调了它们在日常交往中作为社会生物学刺激物的重要性。我们进行了两项实验来研究以下问题:(a) 当与任务相关并作为目标时,人脸或身体部位是否比其他视觉物体处理得更快;以及 (b) 将人脸或身体部位作为干扰物对任务反应时间和错误率的影响。第一个实验的重点是人脸或身体部位,共有五个不同的视觉对象。第二个实验考察了身体的效应部位(如手)和核心部位(如躯干),并与相同的视觉对象配对。共有 36 名参与者参加了这项研究,实验 1(18 人)和实验 2(18 人)各占一半。参与者被要求寻找绿色占位符所指示的目标物品是否与之前出现的单词提示相匹配,同时他们被要求继续忽略红色占位符所包围的单个物体。结果表明,在实验 1 中,被试在找到脸部而非身体部位时反应更快。而在实验 2 中,与其他物体相比,效应物或核心身体部位都没有这种优势。有趣的是,当人脸作为单个分心物出现时,反应时间会增加(实验 1),这表明人脸能吸引注意力。这种效应在效应物或核心身体部位上都没有观察到(实验 2)。这些研究结果表明,人脸比身体部位更有效地吸引注意力。(PsycInfo Database Record (c) 2024 APA, 版权所有)。

期刊介绍: The Canadian Journal of Experimental Psychology publishes original research papers that advance understanding of the field of experimental psychology, broadly considered. This includes, but is not restricted to, cognition, perception, motor performance, attention, memory, learning, language, decision making, development, comparative psychology, and neuroscience. The journal publishes - papers reporting empirical results that advance knowledge in a particular research area; - papers describing theoretical, methodological, or conceptual advances that are relevant to the interpretation of empirical evidence in the field; - brief reports (less than 2,500 words for the main text) that describe new results or analyses with clear theoretical or methodological import.
