    Observed Altruism of Dental Students: An Experiment Using the Ultimatum Game.Parker Crutchfield, Justin Jarvis & Terry Olson - 2017 - Journal of Dental Education 81 (11):1301-1308.
    PURPOSE: The conventional wisdom in dental and medical education is that dental and medical students experience "ethical erosion" over the duration of dental and medical school. There is some evidence for this claim, but in the case of dental education this evidence consists entirely of survey research, which doesn't measure behavior. The purpose of this study was to measure the altruistic behavior of dental students, in order to fill the significant gap in knowledge of how students are disposed to behave, (...)

    Moral Enhancement Can Kill.Parker Crutchfield - forthcoming - Journal of Medicine and Philosophy.
    There is recent empirical evidence that personal identity is constituted by one’s moral traits. If true, this poses a problem for those who advocate for moral enhancement, or the manipulation of a person’s moral traits through pharmaceutical or other biological means. Specifically, if moral enhancement manipulates a person’s moral traits, and those moral traits constitute personal identity, then it is possible that moral enhancement could alter a person’s identity. I go a step further and argue that under the right conditions, (...)

    Being Hungry Affects Oral Size Perception.Parker Crutchfield - 2018 - I-Perception 9 (3).
    Oral size perception is not veridical, and there is disagreement on whether this non-veridicality tends to underestimate or overestimate size. Further, being hungry has been shown to affect oral size perception. In the present study, we investigated the effect of hunger on oral size perception. Overall, being hungry had a small but significant effect on oral size perception and seemed to support that oral size perception tends to underestimate the size of objects. Both hungry and sated participants tended to underestimate (...)

    Cross-Modal Influence on Oral Size Perception.Parker Crutchfield, Connor Mahoney, Cesar Rivera & Vanessa Pazdernik - 2016 - Archives of Oral Biology 61:89-97.
    Objective: Evidence suggests people experience an oral size illusion and commonly perceive oral size inaccurately; however, the nature of the illusion remains unclear. The objectives of the present study were to confirm the presence of an oral size illusion, determine the magnitude (amount) and direction (underestimation or overestimation) of the illusion, and determine whether immediately prior crossmodal perceptual experiences affected the magnitude and direction. Design: Participants (N = 27) orally assessed 9 sizes of stainless steel spheres (1/16 in to 1/2 (...)

    Compulsory Moral Bioenhancement Should Be Covert.Parker Crutchfield - forthcoming - Bioethics.
    Some theorists argue that moral bioenhancement ought to be compulsory. I take this argument one step further, arguing that if moral bioenhancement ought to be compulsory, then its administration ought to be covert rather than overt. This is to say that it is morally preferable for compulsory moral bioenhancement to be administered without the recipients knowing that they are receiving the enhancement. My argument for this is that if moral bioenhancement ought to be compulsory, then its administration is a matter (...)

    The Limits of Deontology in Dental Ethics Education.Parker Crutchfield, Lea Brandt & David Fleming - 2016 - International Journal of Ethics Education 1 (2):183-200.
    Most current dental ethics curricula use a deontological approach to biomedical and dental ethics that emphasizes adherence to duties and principles as properties that determine whether an act is ethical. But the actual ethical orientation of students is typically unknown. The purpose of the current study was to determine the ethical orientation of dental students in resolving clinical ethical dilemmas. First-year students from one school were invited to participate in an electronic survey that included eight vignettes featuring ethical conflicts common (...)

    The Epistemology of Moral Bioenhancement.Parker Crutchfield - 2016 - Bioethics 30 (5):389-396.
    Moral bioenhancement is the potential practice of manipulating individuals’ moral behaviors by biological means in order to help resolve pressing moral issues such as climate change and terrorism. This practice has obvious ethical implications, and these implications have been and continue to be discussed in the bioethics literature. What have not been discussed are the epistemological implications of moral bioenhancement. This article details some of these implications of engaging in moral bioenhancement. The argument begins by making the distinction between moral (...)

    The Ethics of Anti-Aging Clinical Trials.Parker Crutchfield - 2018 - Science and Engineering Ethics 24 (2):441-453.
    Interventions aiming to slow, stop, or reverse the aging process are starting to enter clinical trials. Though this line of research is nascent, it has the potential to not only prevent prolonged human suffering, but also to extend human well-being. As this line of research develops, it is important to understand the ethical constraints of conducting such research. This paper discusses some of these constraints. In particular, it discusses the ethical difficulties of conducting this research in a way that would (...)
