  1. The Impact of the Covid-19 Pandemic on Disgust Sensitivity.Richard J. Stevenson, Supreet Saluja & Trevor I. Case - 2021 - Frontiers in Psychology 11.
    There have been few tests of whether exposure to naturalistic or experimental disease-threat inductions alter disgust sensitivity, although it has been hypothesized that this should occur as part of disgust’s disease avoidance function. In the current study, we asked Macquarie university students to complete measures of disgust sensitivity, perceived vulnerability to disease, hand hygiene behavior and impulsivity, during Australia’s Covid-19 pandemic self-quarantine period, in March/April 2020. These data were then compared to earlier Macquarie university, and other local, and overseas student (...)

  • Disgust Sensitivity Among Women During the COVID-19 Outbreak.Karolina Miłkowska, Andrzej Galbarczyk, Magdalena Mijas & Grazyna Jasienska - 2021 - Frontiers in Psychology 12.
    The emotion of disgust is suggested to be an adaptation that evolved to keep us away from sources of infection. Therefore, individuals from populations with greater pathogen stress should have a greater disgust sensitivity. However, current evidence for a positive relationship between disgust sensitivity and the intensity of infectious diseases in the environment is limited. We tested whether disgust and contamination sensitivity changed in response to the COVID-19 pandemic. Disgust was assessed in 984 women in 2017 and 633 women in (...)

  • Do Islanders Have a More Reactive Behavioral Immune System? Social Cognitions and Preferred Interpersonal Distances During the COVID-19 Pandemic.Ivana Hromatko, Andrea Grus & Gabrijela Kolđeraj - 2021 - Frontiers in Psychology 12.
    Insular populations have traditionally drawn a lot of attention from epidemiologists as they provide important insights regarding transmission of infectious diseases and propagation of epidemics. There are numerous historical instances where isolated populations showed high morbidity once a new virus entered the population. Building upon that and recent findings that the activation of the behavioral immune system depends both upon one’s vulnerability and environmental context, we predicted that, during the COVID-19 pandemic, place of residence explains a significant proportion of variance (...)

  • Behavioral Immune System Responses to Coronavirus: A Reinforcement Sensitivity Theory Explanation of Conformity, Warmth Toward Others and Attitudes Toward Lockdown.Alison M. Bacon & Philip J. Corr - 2020 - Frontiers in Psychology 11.
    Behavioral immune system describes psychological mechanisms that detect cues to infectious pathogens in the immediate environment, trigger disease-relevant responses and facilitate behavioral avoidance/escape. BIS activation elicits a perceived vulnerability to disease which can result in conformity with social norms. However, a response to superficial cues can result in aversive responses to people that pose no actual threat, leading to an aversion to unfamiliar others, and likelihood of prejudice. Pathogen-neutralizing behaviors, therefore, have implications for social interaction as well as illness behaviors (...)

  • Sex Differences in Disgust: Why Are Women More Easily Disgusted Than Men?Laith Al-Shawaf, David M. G. Lewis & David M. Buss - 2018 - Emotion Review 10 (2):149-160.
    Women have consistently higher levels of disgust than men. This sex difference is substantial in magnitude, highly replicable, emerges with diverse assessment methods, and affects a wide array of outcomes—including job selection, mate choice, food aversions, and psychological disorders. Despite the importance of this far-reaching sex difference, sound theoretical explanations have lagged behind the empirical discoveries. In this article, we focus on the evolutionary-functional level of analysis, outlining hypotheses capable of explaining why women have higher levels of disgust than men. (...)
