Roles of domain knowledge and working memory capacity in components of skill in Texas Hold’Em poker

Domain knowledge is a powerful predictor of success in many complex tasks, but do general cognitive abilities also play a role? To investigate this question, we had 155 participants representing a wide range of poker experience and skill complete tests of poker knowledge, working memory capacity (WMC), and two components of skill in Texas Hold’Em poker: the ability to remember hands and the ability to evaluate hands. Not surprisingly, poker knowledge positively predicted performance in all of the Hold’Em tasks. However, WMC added significantly to the prediction, and there was no evidence for interactions between poker knowledge and WMC. That is, WMC was as important as a predictor of performance at high levels of poker knowledge as at low levels, suggesting that domain knowledge may not always enable circumvention of WMC in domain-relevant tasks.     

Social benefits of humility: Initiating and maintaining romantic relationships

Previous research has highlighted the social nature of humility. In three studies, we provide evidence that humility facilitates the initiation and maintenance of romantic relationships. In Study 1, very humble potential dating partners, relative to less humble partners, were rated more favorably and were more likely to elicit intentions to initiate a romantic relationship. Study 2 was a conceptual replication of Study 1 that provided evidence that participants find humble potential dating partners more attractive than arrogant dating partners. In Study 3, we examined perceptions of humility in participants in proximal or long-distance relationships. We found that humility buffers against unforgiveness in long-distant relationships. Although long-distance relationships were associated with greater unforgiveness, this effect was only present when partners were viewed as having low humility. Together, these findings highlight the social benefits of humility in initiating and maintaining romantic relationships.     

Religious Coping,Coping Resources,and Depressive Symptoms: Test of a Mediation Model

This study examined the relationships between religious coping, coping resources, and depressive symptoms. The authors tested whether coping resources explained the link between religious coping and depressive symptoms in a sample of 349 college students. Results indicated that coping resources partially mediated the relationship between negative religious coping and depressive symptoms, primarily through decreased social ease. The results offered no evidence that coping resources mediated the relationship between positive religious coping and depressive symptoms.     

One and Done? Optimal Decisions From Very Few Samples

In many learning or inference tasks human behavior approximates that of a Bayesian ideal observer, suggesting that, at some level, cognition can be described as Bayesian inference. However, a number of findings have highlighted an intriguing mismatch between human behavior and standard assumptions about optimality: People often appear to make decisions based on just one or a few samples from the appropriate posterior probability distribution, rather than using the full distribution. Although sampling‐based approximations are a common way to implement Bayesian inference, the very limited numbers of samples often used by humans seem insufficient to approximate the required probability distributions very accurately. Here, we consider this discrepancy in the broader framework of statistical decision theory, and ask: If people are making decisions based on samples—but as samples are costly—how many samples should people use to optimize their total expected or worst‐case reward over a large number of decisions? We find that under reasonable assumptions about the time costs of sampling, making many quick but locally suboptimal decisions based on very few samples may be the globally optimal strategy over long periods. These results help to reconcile a large body of work showing sampling‐based or probability matching behavior with the hypothesis that human cognition can be understood in Bayesian terms, and they suggest promising future directions for studies of resource‐constrained cognition.     

OF MIRACLES AND METAPHYSICS: A PENTECOSTAL‐CHARISMATIC AND PROCESS‐RELATIONAL DIALOGUE

This article is comprised of a dialogue between Pentecostal‐Charismatic and Process‐Relational theologies on the perennial issue of miracles. The language of supernaturalism, widely employed by Pentecostal‐Charismatic theologians, is contrasted with the metaphysical naturalism of Process‐Relational theology; it is proposed that a philosophically and scientifically sensitive theology of miracles is possible through a synthesis of both traditions. Themes such as nonmaterialism over materialism, spiritual experience, and prayer for healing miracles are explored. A theology of miracles, mutually informed by both Pentecostal‐Charismatic and Process‐Relational theologies, may focus less on whether or not miracles are possible, but instead focus more on what kind of miracles human beings might value most. By mutually engaging a theology of nonsupernatural, metaphysically grounded miracles, Pentecostal‐Charismatic and Process‐Relational theologians may collaborate to establish the groundwork for creative scientific enterprises, especially in the non‐Western world where Pentecostalism continues to experience its most rapid growth, Such perspectives may eventually lead to cutting‐edge discoveries about the fundamental nature of, and God's interaction with, reality itself. Implications for future research are proposed.     

In-Home Parent-Child Interaction Therapy: Clinical Considerations

ABSTRACT

Parent-Child Interaction Therapy (PCIT) is an empirically-supported behavioral parent training program designed to be administered in a clinic or laboratory-based setting. Recently, an empirical investigation revealed that in-home PCIT produced comparable results as the PCIT trials conducted in more controlled environments (this issue). Administering PCIT in a home setting carries both drawbacks and advantages. This article provides an overview of both the positive and negative clinical aspects of conducting in-home PCIT and presents effective solutions to potential treatment barriers.     

When Fatigue Turns Deadly: The Association Between Fatigue and Racial Bias in the Decision to Shoot

Racial bias in the decision to shoot can be minimized if individuals have ample cognitive resources to regulate automatic reactions. However, when individuals are fatigued, cognitive control may be compromised, which can lead to greater racial bias in shoot/don't-shoot decisions. The current studies provide evidence for this hypothesis experimentally using undergraduate participants (Study 1) and in a correlational design testing police recruits (Study 2). These results shed light on the processes underlying the decision to shoot and, given the high prevalence of fatigue among police officers, may have important practical implications.     

Can Religion Promote Virtue?: A More Stringent Test of the Model of Relational Spirituality and Forgiveness

Rather than simply studying whether religious individuals are more forgiving than nonreligious individuals, recent research has focused on how religion may promote a more fluid and efficient forgiveness process. The present studies sought to strengthen evidence for a model of relational spirituality and forgiveness (Davis, Hook, & Worthington, 2008 Davis, D. E., Hook, J. N. and Worthington, E. 2008. Relational spirituality and forgiveness: The roles of attachment to God, religious coping, and viewing the transgression as a desecration. Journal of Psychology and Christianity, 27: 293–301.  [Google Scholar]), given the reliance of prior studies on cross-sectional designs that did not control for hurtfulness of the offense. In Study 1, spiritual appraisals predicted unforgiveness, controlling for hurtfulness and other covariates. Furthermore, using structural equation modeling, empathy was found to partially mediate the relationship between spiritual appraisals and unforgiveness. In Study 2, participants (N = 123) completed a survey weekly for 6 weeks that included measures of relational spirituality and forgiveness. Appraisals of relational spirituality predicted subsequent unforgiveness, as well as the rate of decline in unforgiveness. Thus, using a more stringent test, we found additional evidence for the model.
