Three problems for the evolutionary debunking argument

In attempting to debunk moral realism through an appeal to evolutionary facts, debunkers face a series of problems, which we label the problems of scope, corrosiveness, and post-hoc justification. To overcome these problems, debunkers must assume certain metaphysical or epistemological positions, or otherwise pre-establish them. In doing so, they must assume or pre-establish the very conclusion they seek in advancing the argument. This means that such debunking arguments either beg the question against the moral realist or are undermined as standalone metaethical arguments.     

Affective variability in depression: Revisiting the inertia–instability paradox

How can depression be associated with both instability and inertia of affect? Koval et al. (2013, Emotion, 13, 1132) showed that this paradox can be solved by accounting for the statistical overlap between measures of affect dynamics. Nevertheless, these measures are still often studied in isolation. The present study is a replication of the Koval et al. study. We used experience sampling data (three times a day, 1 month) of 462 participants from the general population and a subsample thereof (N = 100) selected to reflect a uniform range of depressive symptoms. Dynamics measures were calculated for momentary negative affect scores. When adjusting for the overlap among affect dynamics measures, depression was associated with ‘dispersion’ (SD) but not ‘instability’ (RMSSD) or ‘inertia’ (AR) of negative affect. The association between dispersion and depression became non‐significant when mean levels of negative affect were adjusted for. These findings substantiate the evidence that the presumed association between depression and instability is largely accounted for by the SD, while the association between dispersion and depression may largely reflect mean levels of affect. Depression may thus not be related to higher instability per se, which would be in line with theories on the adaptive function of moment‐to‐moment fluctuations in affect.     

An Examination and Interrogation of African American Males’ Racial Identity,Prosocial Behaviors and Aggression

Using multiple regression analysis and Pearson’s R, the current exploratory study of 89 African American male adolescents (M = 12.5 years old) examined relationships among REI (i.e., 20 as a socialization product of identity formation processes), prosocial behaviors (i.e., represented as supportive behavioral orientation in response to stress), and aggression (i.e., a reactive coping strategy). Significant relationships among racial public regard, age, and verbal aggression emerged. Older adolescents believed that other people have lower regard for their race, and this predicted an increase in verbal aggression. These findings demonstrate the importance of understanding contextual factors when examining outcomes.     

In‐group relevance facilitates learning across existing and new associations

Studies have shown that attention prioritizes stimuli associated with the in‐group. However, the extent to which this so‐called in‐group favoritism is driven by relevance is not clear. Here, we investigated this issue in a group of university rowers using a novel perceptual matching task based on the team label–color associations. Across three experiments, participants showed enhanced performance for the in‐group stimulus regardless of its familiarity level. These findings confirmed the role of relevance in in‐group favoritism. In a further control study, the advantage for certain stimuli was not found in an independent sample of participants who were not identified with the teams but were familiar with the label–color associations, indicating that in‐group relevance was necessary for the in‐group favoritism. Together, these findings suggest that in‐group relevance facilitates learning across existing and new associations. The consequences of these findings for understanding in‐group effects on perceptual processing are discussed.     

Predicting Successful Responses to Emergencies: the Emergency Responsiveness Scale

People respond to disasters in a variety of ways. Some individuals respond to disasters or emergencies with panicked activity while others mobilize resources without panicking. In this article, we propose that the individual response to emergencies is determined by Emergency Responsiveness, the manner in which an individual appraises an emergency situation. We believe Emergency Responsiveness consists of four factors: Risk Taking, Experience with Emergencies, Emergency Anxiety, and Emergency Preparation. In Study One, each of the four subscales of Emergency Responsiveness correlated with personality traits in the hypothesized directions, providing evidence of construct validity. In Study Two, we establish criterion-related validity by demonstrating that a sample of first-responders scored significantly higher than a control sample on all four dimensions. Our results support our hypothesis that Emergency Responsiveness is a measurable individual difference. Implications for first responders and emergency services are discussed.     

Attachment relationships and physical activity motivation of college students

This study was designed to assess the link of attachment relationships with physical activity motivation. Potential mediators of this link were examined in a cross-sectional study targeting college student physical activity motivation and behaviour. Participants completed self-reports of attachment relationships (with mother, father and best friend), self-determined motivation for physical activity, physical activity behaviour and the hypothesised mediator variables of perceived competence, autonomy and relatedness. The results provide support for the mediating role of these variables in the association of father attachment with self-determined motivation. Meaningful variance in self-determined motivation for physical activity and physical activity behaviour was explained. Overall, attachment relationships appear to be relevant, albeit modestly, to physical activity motivation of college students. The findings support continued efforts to integrate attachment and motivational perspectives in the study of college student health behaviour.
