The Hearts and Guts of White People

Beginning with the experience of a white woman's stomach seizing up in fear of a black man, this essay examines some of the ethical and epistemological issues connected to white ignorance. In conversation with Charles Mills on the epistemology of ignorance, I argue that white ignorance primarily operates physiologically, not cognitively. Drawing critically from psychology, neurocardiology, and other medical sciences, I examine some of the biological effects of racism on white people's stomachs and hearts. I argue for a nonideal medical theory focused on improving wellness in a society that systematically has damaged the health of people of color. The essay concludes that to be fully successful, critical philosophy of race must examine not just the financial, legal, political, and other forms of racism, but also its biological and physiological operations.     

Baseline reinforcement rate and resurgence of destructive behavior

Concepts from behavioral momentum theory, along with some empirical findings, suggest that the rate of baseline reinforcement may contribute to the relapse of severe destructive behavior. With seven children who engaged in destructive behavior, we tested this hypothesis in the context of functional communication training by comparing the effects of different baseline reinforcement rates on resurgence during a treatment challenge (i.e., extinction). We observed convincing resurgence of destructive behavior in four of seven participants, and we observed more resurgence in the condition associated with high‐rate baseline reinforcement (i.e., variable‐interval 2 s in Experiment 1 or fixed‐ratio 1 in Experiment 2) compared to a low‐rate baseline reinforcement condition. We discuss the implications of these results relative to schedules of reinforcement in the treatment of destructive behavior and strategies to mitigate resurgence in clinical settings.     

Effects of a handwashing intervention package on handwashing in preschool children

Young children who attend out‐of‐home care (e.g., preschool) are more susceptible to infections than children who do not attend out‐of‐home care. Previous research suggests handwashing is effective in reducing risk of infection and illness. However, research suggests that individuals do not routinely wash their hands using methods that healthcare agencies, such as the Centers for Disease Control and Prevention, have determined best practice. We evaluated the effects of a multicomponent handwashing intervention package on correct handwashing across groups of preschool children. Furthermore, we measured the degree to which their hands were clean using premeasures and postmeasures. Results suggest the intervention package was effective at increasing both correct handwashing and cleanliness of participants' hands.     

Aims and Exclusivity

If belief has an aim by being a (quasi) intentional activity, then it ought to be the case that the aim of belief can be weighed against other aims one might have. However, this is not so with the putative truth aim of belief: from the first‐person perspective, one can only be motivated by truth considerations in deliberation over what to believe (exclusivity). From this perspective then, the aim cannot be weighed. This problem is captured by David Owens's Exclusivity Objection to belief having an aim (2003). Conor McHugh (2012; 2013) has responded to this problem by denying the phenomenon of exclusivity and replacing it with something weaker: demandingness. If deliberation over what to believe is characterised by demandingness and not exclusivity, this allows for the requisite weighing of the truth aim. I argue against such a move by suggesting that where non‐evidential considerations play a role in affecting what we believe, these considerations merely change the standards required for believing in a particular context, they do not provide non‐evidential reasons for forming or withholding belief, which are considered as such from the deliberative perspective. Exclusivity thus remains, and so too does Owens's objection.     

The Emotional Foundation of Political Cognition: The Impact of Extrinsic Anxiety on the Formation of Political Tolerance Judgments

Common sense recognizes emotion's ability to influence judgments. We argue that affective processes, in addition to generating feeling states, also influence how political cognition is manifested. Drawing on the theory of affective intelligence, we examine the role that anxiety plays in how and when people rely on predispositions and when they rely on contemporaneous information in making political tolerance judgments. We report on two experimental studies to test our arguments. In the first study we find that extrinsic anxiety generates a resistance response among subjects who hold a strong predisposition and a receptive response among those who do not. In the second study we present subjects with explicit "frames" exposing them to a pro- or anti-free speech message. We find that extrinsic anxiety enhances responsiveness to frames while an absence of anxiety diminishes the impact of these frames. Taken together these results show that affective processes shape how people make political judgments.     

Further Operationalization of Intra‐Team Communication in Sports: An Updated Version of the Scale of Effective Communication in Team Sports (SECTS‐2)

Sullivan & Feltz (2003 ) offered a preliminary multidimensional measure of communication in team sports, the Scale for Effective Communication in Team Sports (SECTS). The current research attempted to further the development and support for the psychometric properties and validity of the measure. In one study, 350 athletes completed an updated version of the SECTS. Confirmatory factor analyses showed good support for the 4‐factor structure. Correlations to team cohesion offer construct validity for the scale. A second study, with an independent sample (N = 79), revealed that team performance was negatively related to the communication of Distinctiveness at the team level. This updated version of the SECTS represents a parsimonious, valid, and reliable operational definition of sports‐specific effective team communication.     

MR Diffusion Tensor Imaging: A Window into White Matter Integrity of the Working Brain

As Norman Geschwind asserted in 1965, syndromes resulting from white matter lesions could produce deficits in higher-order functions and “disconnexion” or the interruption of connection between gray matter regions could be as disruptive as trauma to those regions per se. The advent of in vivo diffusion tensor imaging, which allows quantitative characterization of white matter fiber integrity in health and disease, has served to strengthen Geschwind’s proposal. Here we present an overview of the principles of diffusion tensor imaging (DTI) and its contribution to progress in our current understanding of normal and pathological brain function.
