Abstract

Ostensibly serving to restrict contact with disease vectors, humans exhibit aversion toward cues heuristically inferred as pathogenic. This restriction could lead perceivers to downregulate their interest in food consumption, even if such cues may not connote actual disease threats. This proclivity to avoid disease led us to consider how heuristic disease cues inform interest in foods. Participants evaluated a hypothetical food preparer that varied in the presence of heuristic cues to disease transmission (i.e., physical deformities versus healthy control). Individuals with low levels of perceived infectability were more discerning of the social target as a function of disease cues, whereas heightened levels of this trait fostered an overall aversion to targets regardless of health status. Results provide continued evidence for how pathogen avoidance motives compete with other somatic motives.

食物偏好中身体畸形疾病传播的功能启发式。
表面上是为了限制与疾病媒介的接触,人类对启发式推断为致病的线索表现出厌恶。这种限制可能会导致感知者降低他们对食物消费的兴趣,即使这种暗示可能并不意味着实际的疾病威胁。这种避免疾病的倾向促使我们考虑启发式疾病线索如何影响对食物的兴趣。参与者评估了一个假设的食品制备者,该制备者在疾病传播的启发式线索(即身体畸形与健康对照)的存在下有所不同。感知感染性水平较低的个体更能识别作为疾病线索函数的社会目标,而这种特征水平的提高则会导致无论健康状况如何,对目标的总体厌恶。研究结果为避免病原体的动机如何与其他躯体动机竞争提供了持续的证据。

期刊介绍: Evolutionary Psychological Science is an international, interdisciplinary journal that publishes empirical research, theoretical contributions, literature reviews, and commentaries addressing human evolved psychology and behavior. The Journal especially welcomes submissions on non-humans that inform human psychology and behavior, as well as submissions that address clinical implications and applications of an evolutionary perspective. The Journal is informed by all the social and life sciences, including anthropology, biology, criminology, law, medicine, philosophy, political science, and the humanities, and welcomes contributions from these and related fields that contribute to the understanding of human evolved psychology and behavior. Submissions should not exceed 10,000 words, all inclusive.
