No pairing problem

Many have thought that there is a problem with causal commerce between immaterial souls and material bodies. In Physicalism or Something Near Enough, Jaegwon Kim attempts to spell out that problem. Rather than merely posing a question or raising a mystery for defenders of substance dualism to answer or address, he offers a compelling argument for the conclusion that immaterial souls cannot causally interact with material bodies. We offer a reconstruction of that argument that hinges on two premises: Kim’s Dictum and the Nowhere Man principle. Kim’s Dictum says that causation requires a spatial relation. Nowhere Man says that souls can’t be in space. By our lights, both premises can be called into question. We’ll begin our evaluation of the argument by pointing out some consequences of Kim’s Dictum. For some, these will be costs. We will then present two defeaters for Kim’s Dictum and a critical analysis of Kim’s case for Nowhere Man. The upshot is that Kim’s argument against substance dualism fails.     

Sex differences in cooperation: a meta-analytic review of social dilemmas

Although it is commonly believed that women are kinder and more cooperative than men, there is conflicting evidence for this assertion. Current theories of sex differences in social behavior suggest that it may be useful to examine in what situations men and women are likely to differ in cooperation. Here, we derive predictions from both sociocultural and evolutionary perspectives on context-specific sex differences in cooperation, and we conduct a unique meta-analytic study of 272 effect sizes-sampled across 50 years of research-on social dilemmas to examine several potential moderators. The overall average effect size is not statistically different from zero (d = -0.05), suggesting that men and women do not differ in their overall amounts of cooperation. However, the association between sex and cooperation is moderated by several key features of the social context: Male-male interactions are more cooperative than female-female interactions (d = 0.16), yet women cooperate more than men in mixed-sex interactions (d = -0.22). In repeated interactions, men are more cooperative than women. Women were more cooperative than men in larger groups and in more recent studies, but these differences disappeared after statistically controlling for several study characteristics. We discuss these results in the context of both sociocultural and evolutionary theories of sex differences, stress the need for an integrated biosocial approach, and outline directions for future research.     

Shyness as a moderator of the link between advanced maturity and early adolescent risk behavior

Advanced maturity in early adolescence has previously been linked with several risk behaviors. In this study, we examine whether shyness and gender might moderate this link. The participants were 750 early adolescents (M(age) = 13.73; 390 girls and 360 boys), followed for one year. We conducted analyses with shyness and gender as moderators of the links between advanced maturity and different types of risk behavior, and between one risk behavior and another. Despite differential patterns for boys and girls, the results suggest that being shy or not being shy modifies the links between advanced maturity and risk behavior primarily for boys. For boys, shyness reduces relationships between advanced maturity and risk behavior, whereas not being shy exacerbates the relationships between advanced maturity and high-risk behavior. Controlling for romantic involvement and peer victimization did not alter the moderating effects, thus failing to support the idea that the weaker links for shy youths were due to shy youths not being drawn into advanced peer groups by romantic partners or peers. Thus, shyness might serve as a buffer against risk behavior in early adolescence.     

Is identifying with a historically victimized group good or bad for your health? Transgenerational post‐traumatic stress and collective victimization

An abundance of evidence suggests that the consequences of collective ingroup victimization can traverse generations, even among group members who are not direct descendants of victims. It nevertheless remains unclear why only some group members experience vicarious victimization. To examine the role of collective identification in the transmission of trauma across generations, we surveyed members of a Jewish community—including descendants of holocaust survivors and others who were not descendants of the holocaust survivors. Among non‐descendants, Jewish identification was negatively associated with symptoms of post‐traumatic stress disorder (PTSD). In contrast, among descendants, Jewish identification was positively associated with PTSD symptoms. Further, familial willingness to discuss the holocaust mediated the relationship between identification and PTSD symptoms. Additional analyses confirmed that these effects were specific to holocaust‐related PTSD symptoms and not general anxiety or depression. These findings suggest that collective identity may both buffer and enhance the effects of collective victimization on mental health. Copyright © 2011 John Wiley & Sons, Ltd.     

Behavioral and social cognitive processes in preschool children's social dominance

This longitudinal, naturalistic study addressed behavioral and social cognitive processes implicated in preschool children's social dominance. In the first objective, we examined the degree to which peer aggression, affiliation, and postaggression reconciliation predicted social dominance across a school year. Consistent with predictions, all three predicted dominance early in the year while only affiliation predicted dominance later in the year, suggesting that aggression, affiliation, and reconciliation were used to establish social dominance where affiliation was used to maintain it. In the second, exploratory, objective we tested the relative importance of social dominance and reconciliation (the Machiavellian and Vygotskian intelligence hypotheses, respectively) in predicting theory of mind/false belief. Results indicated that social dominance accounted for significant variance, beyond that related to reconciliation and affiliation, in predicting theory of mind/false belief status. Results are discussed in terms of specific behavioral and social cognitive processes employed in establishing and maintaining social dominance.     

By any means necessary: the effects of regulatory focus and moral conviction on hostile and benevolent forms of collective action

In two studies, we investigate the effect of individuals' promotion and prevention focus on engagement in collective action. We show that responding to group-based disadvantage out of a sense of moral conviction motivates prevention-oriented- but not promotion-oriented- individuals to engage in collective action. Furthermore, holding such strong moral convictions about the fair treatment of their group causes the prevention-oriented to disregard societal rules against hostile forms of collective action (i.e., forms of action that are aimed at harming the interests of those held responsible for the group's disadvantage). Study 1 showed that prevention-oriented individuals, but not promotion-oriented individuals, with a strong moral conviction about the fair treatment of their group are willing to support both hostile and benevolent forms of collective action. Study 2 replicated this effect and showed that for prevention-oriented individuals but not for promotion-oriented individuals, holding a strong moral conviction about the fair treatment of the group overrides moral objections to hostile forms of collective action in the decision to support these forms of action.     

Drugs, mental instruments, and self-control

The instrumental model offered by Müller & Schumann (M&S) is broadened to apply not only to drugs, but also to other methods of self-control, including the use of mental constructs to produce adaptive changes in behavior with the possibility of synergistic interactions between various instruments.
