Cooperation and coordination across cultures and contexts: Individual,sociocultural, and contextual factors jointly influence decision making in the volunteer's dilemma game

What factors promote or hinder volunteering within organizations and groups? This paper simultaneously explores the impact of individual, contextual, and sociocultural variables on decision making in a special type of social dilemma: the volunteer's dilemma game (VDG). The VDG provides a controlled experimental method for studying volunteering behaviors in an anonymous interactive environment. We developed six variations of the VDG and administered them to economics students in five different cultures (N_total = 603). Among other things, these VDGs varied whether the potential benefits of volunteering were certain or uncertain. Although the overall level of volunteering did not vary substantially across most cultural groups, we found that culture interacted with the size and (un)certainty of the benefits associated with volunteering, to influence volunteering decisions. We also found that religiosity (but not religious affiliation per se) increases volunteering and that men are less likely to volunteer when the returns to doing so are certain. These results extend our knowledge of behaviors in the VDG, and their potential drivers, with clear implications for understanding how culture, individual characteristics, and context jointly influence prosocial behavior and coordination.     

Dispositions and subjunctives

It is generally agreed that dispositions cannot be analyzed in terms of simple subjunctive conditionals (because of what are called “masked dispositions” and “finkish dispositions”). I here defend a qualified subjunctive account of dispositions according to which an object is disposed to Φ when conditions C obtain if and only if, if conditions C were to obtain, then the object would Φ ceteris paribus. I argue that this account does not fall prey to the objections that have been raised in the literature.     

Concurrent and Longitudinal Links Between Children’s Externalizing Behavior in School and Observed Anger Regulation in the Mother–Child Dyad

Two studies examined relations between children’s anger regulation and externalizing behavior utilizing community samples. The first study included 58 children from preschool through second grade and examined concurrent associations between regulation and externalizing behavior. The second study included 40 preschool and kindergarten children and examined regulation and externalizing behavior 2 years later. In both studies, anger reactivity and regulation strategies were assessed during home visits using the same observational task. In study 1, teachers completed a problem behavior checklist shortly after the home visit. In study 2, teachers completed a problem behavior checklist 2 years later. Results indicate that the dysregulation of anger is associated with externalizing problems concurrently and two years later. Findings also suggest that attention refocusing may be a successful strategy for reducing anger and externalizing problems among highly reactive children.     

Coping with disappointing outcomes: Retroactive pessimism and motivated inhibition of counterfactuals

Having failed to achieve a desired goal, people may use retroactive pessimism as a defense mechanism, concluding that chances of success were not too good to begin with. To make this judgment, one must block counterfactual alternatives suggesting that success was, in fact, quite likely. Facing a bitter disappointment, the perceiver is highly motivated to inhibit upward counterfactuals, thus increasing the perceived inevitability of failure and finding solace in the acceptance of inescapable fate. Two experiments explored the hypothesized link between counterfactuals inhibition and retroactive pessimism. In the first experiment, it was found that participants experiencing grave disappointment, following a near miss, judged their chances of achieving their goal less favorably, compared to participants who had missed their goal by far. An analysis on participants’ counterfactual judgments suggested that this effect was mediated by participants’ perceptions of counterfactual events. The second experiment demonstrated that retroactive pessimism and counterfactual inhibition seem to be unique to situations in which the negative outcome resulted from uncontrollable rather than controllable events, thus corroborating the functional characterization of counterfactual thinking as well as the link between retroactive pessimism and disappointment.     

Method and the Structure of Knowledge in Spinoza

It is argued, first, that although Spinoza's early Treatise on the Emendation of the Intellect does show evidence of a foundationalist approach to the justification of knowledge, there are good reasons to think he came to find such an approach unsatisfactory; and second, that the Ethics notion of certainty as adequate knowledge of one's knowledge is a justificational concept which is holistic in that any instance of such certainty depends on knowledge of the entire basic metaphysical system. Finally it is shown that Spinoza's having come to hold a nonlinear view regarding the justificational structure of knowledge explains why he chose to present his philosophy in the geometric form, and why he never succeeded in formulating a method of discovery.     

Peers influence adolescent reward processing,but not response inhibition

Most adolescent risk taking occurs in the presence of peers. Prior research suggests that peers alter adolescents’ decision making by increasing reward sensitivity and the engagement of regions involved in the processing of rewards, primarily the striatum. However, the potential influence of peers on the capacity for impulse control, and the associated recruitment of the brain’s control circuitry, has not yet been adequately examined. In the current study, adolescents underwent functional neuroimaging while they completed interleaved rounds of risk-taking and response-inhibition tasks. Social context was manipulated such that the participants believed they were either playing alone and unobserved, or watched by an anonymous peer. Compared to those who completed the tasks alone, adolescents in the peer condition took more risks during the risk-taking task and exhibited relatively heightened activation of the striatum. Activity within this striatal region also predicted individual differences in overall risk taking. In contrast, the presence of peers had no effect on behavioral response inhibition and had minimal impact on the engagement of typical cognitive control regions. In a subregion of the anterior insula engaged mutually by both tasks, activity was again found to be sensitive to social context during the risk-taking task, but not during the response-inhibition task. These findings extend the evidence that the presence of peers biases adolescents towards risk taking by increasing reward sensitivity rather than disrupting cognitive control.
