On the classification of diseases

Identifying the necessary and sufficient conditions for individuating and classifying diseases is a matter of great importance in the fields of law, ethics, epidemiology, and of course, medicine. In this paper, I first propose a means of achieving this goal, ensuring that no two distinct disease-types could correctly be ascribed to the same disease-token. I then posit a metaphysical ontology of diseases—that is, I give an account of what a disease is. This is essential to providing the most effective means of interfering with disease processes. Following existing work in the philosophy of medicine and epidemiology (primarily Christopher Boorse; Caroline Whitbeck; Alexander Broadbent), philosophy of biology (Joseph LaPorte; D.L. Hull), conditional analyses of causation (J.L. Mackie; David Lewis), and recent literature on dispositional essentialism (Stephen Mumford and Rani Anjum; Alexander Bird), I endorse a dispositional conception of disease. Following discussion of various conceptions of disease-identity, their relations to the clinical and pathological effects of the diseases in question, and how diseases are treated, I conclude (i) that diseases should be individuated by their causes, and (ii) that diseases are causal processes best seen as simultaneously acting sequences of mutually manifesting dispositions.

Do Trust-Based Beliefs Mediate the Associations of Frequency of Private Prayer with Mental Health? A Cross-Sectional Study

Significant associations of private prayer with mental health have been found, while mechanisms underlying these associations are largely unknown. This cross-sectional online study (N = 325, age 35.74, SD 18.50, 77.5 % females) used path modeling to test if trust-based beliefs (whether, when, and how prayers are answered) mediated the associations of prayer frequency with the Anxiety, Confusion, and Depression Profile of Mood States-Short Form scales. The association of prayer and depression was fully mediated by trust-based beliefs; associations with anxiety and confusion were partially mediated. Further, the interaction of prayer frequency by stress was associated with anxiety.     

The Rhetoric of Racism: Revisiting the Creation of the Psychological Institute of the Republic of South Africa (1956–1962)

This paper revisits the 1962 splitting of the South African Psychological Association (SAPA), when disaffected Afrikaner psychologists broke away to form the whites‐only Psychological Institute of the Republic of South Africa (PIRSA). It presents an analysis of the rhetorical justification for forming a new professional association on principles at odds with prevailing international norms, demonstrating how the episode involved more than the question of admitting black psychologists to the association. In particular, the paper argues that the SAPA‐PIRSA separation resulted from an Afrikaner nationalist reading of the goals of psychological science. PIRSA, that is, insisted on promoting a discipline committed to the ethnic‐national vision of the apartheid state. For its part, SAPA's racial integration was of a nominal order only, ostensibly to protect itself from international sanction. The paper concludes that, in a racist society, it is difficult to produce anything other than a racist psychology.     

Social Dominance and the Cultural Politics of Immigration

We argue that conflict over immigration largely concerns who bears the burden of cultural transaction costs, which we define as the costs associated with overcoming cultural barriers (e.g., language) to social exchange. Our framework suggests that the ability of native‐born citizens to push cultural transaction costs onto immigrant out‐groups serves as an important expression of social dominance. In two novel studies, we demonstrate that social dominance motives condition emotional responses to encountering cultural transaction costs, shape engagement in cultural accommodation behavior toward immigrants, and affect immigration attitudes and policy preferences.     

Children Use Temporal Cues to Learn Causal Directionality

The ability to learn the direction of causal relations is critical for understanding and acting in the world. We investigated how children learn causal directionality in situations in which the states of variables are temporally dependent (i.e., autocorrelated). In Experiment 1, children learned about causal direction by comparing the states of one variable before versus after an intervention on another variable. In Experiment 2, children reliably inferred causal directionality merely from observing how two variables change over time; they interpreted Y changing without a change in X as evidence that Y does not influence X. Both of these strategies make sense if one believes the variables to be temporally dependent. We discuss the implications of these results for interpreting previous findings. More broadly, given that many real‐world environments are characterized by temporal dependency, these results suggest strategies that children may use to learn the causal structure of their environments.     

The way I make you feel: How relatedness and compassionate goals promote partner’s relationship satisfaction

Research has investigated the role of three basic psychological needs as proposed by Self-Determination Theory – autonomy, competence, and relatedness – in explaining relationship satisfaction. Research has also explored how relatedness specifically increases prosocial motivations in the individual but has not focused on the role of relatedness in shaping partners’ relationship functioning over time. This research takes a dyadic perspective that proposes that relatedness fulfillment fosters compassionate goals, which in turn predict increases in partner’s satisfaction. Forty-five heterosexual dating couples were asked about their relatedness need fulfillment, compassionate goals, and relationship satisfaction. Relationship satisfaction was assessed again four weeks later. Results showed that one’s own relatedness fulfillment, but not one’s partner’s relatedness fulfillment at Time 1 uniquely predicts partner’s increased satisfaction at Time 2, and that this is mediated by one’s own higher compassionate goals. These findings highlight the dyadic importance of having one’s needs met in promoting relationship functioning over time.     

Attentional responses on an auditory oddball predict false memory susceptibility

Attention and memory are highly integrated processes. Building on prior behavioral investigations, this study assesses the link between individual differences in low-level neural attentional responding and false memory susceptibility on the misinformation effect, a paradigm in which false event memories are induced via misleading post-event information. Twenty-four subjects completed the misinformation effect paradigm after which high-density (256-channel) EEG data was collected as they engaged in an auditory oddball task. Temporal-spatial decomposition was used to extract two attention-related components from the oddball data, the P3b and Classic Slow Wave. The P3b was utilized as an index of individual differences in salient target attentional responding while the slow wave was adopted as an index of variability in task-level sustained attention. Analyses of these components show a significant negative relationship between slow-wave responses to oddball non-targets and perceptual false memory endorsements, suggestive of a link between individual differences in levels of sustained attention and false memory susceptibility. These findings provide the first demonstrated link between individual differences in basic attentional responses and false memory. These results support prior behavioral work linking attention and false memory and highlight the integration between attentional processes and real-world episodic memory.
