The tendency to attend to and avoid cues to pathogens varies across individuals and contexts. Researchers have proposed that this variation is partially driven by immunological vulnerability to infection, though support for this hypothesis is equivocal. One key piece of evidence (Miller & Maner, 2011) shows that participants who have recently been ill-and hence may have a reduced ability to combat subsequent infection-allocate more attention to faces with infectious-disease cues than do participants who have not recently been ill. The current article describes a direct replication of this study using a sample of 402 individuals from the University of Michigan, the University of Glasgow, and Vrije Universiteit Amsterdam-more than 4 times the sample size of the original study. No effect of illness recency on attentional bias for disfigured faces emerged. Though it did not support the original finding, this replication provides suggestions for future research on the psychological underpinnings of pathogen avoidance.
个体和情境的差异会导致人们对病原体线索的关注和回避倾向有所不同。研究人员提出,这种差异部分是由感染的免疫脆弱性驱动的,但对这一假设的支持尚存在争议。一项关键证据(Miller 和 Maner,2011)表明,与最近没有生病的参与者相比,最近生病且可能降低后续感染抵抗力的参与者会更多地关注具有传染病线索的面孔。本文使用来自密歇根大学、格拉斯哥大学和阿姆斯特丹自由大学的 402 名个体的样本对该研究进行了直接复制,这比原始研究的样本量多了四倍以上。最近生病对畸形面孔注意力偏差的影响并不明显。虽然该研究没有支持最初的发现,但这次复制为未来关于病原体回避的心理基础的研究提供了建议。
