How leaders self-regulate their task performance: evidence that power promotes diligence, depletion, and disdain

When leaders perform solitary tasks, do they self-regulate to maximize their effort, or do they reduce effort and conserve their resources? Our model suggests that power motivates self-regulation toward effective performance-unless the task is perceived as unworthy of leaders. Our 1st studies showed that power improves self-regulation and performance, even when resources for self-regulation are low (ego depletion). Additional studies showed that leaders sometimes disdain tasks they deem unworthy, by withholding effort (and therefore performing poorly). Ironically, during ego depletion, leaders skip the appraisal and, therefore, work hard regardless of task suitability, so that depleted leaders sometimes outperform nondepleted ones. Our final studies replicated these patterns with different tasks and even with simple manipulation of framing and perception of the same task (Experiment 5). Experiment 4 also showed that the continued high exertion of leaders when depleted takes a heavy toll, resulting in larger impairments later. The judicious expenditure of self-control resources among powerful people may help them prioritize their efforts to pursue their goals effectively.     

Bioethics and Pastoral Concern: Some Possible New Directions in Pastoral Theology

This special issue of the journal is comprised of papers given at a conference in May 2011 at the University of Texas Health Science Center at Houston on the theme of “Social Justice and the Health Professions.” This article offers the following rationale for this special issue in particular and for pastoral theologians to contribute to bioethics in general: (1) two contemporary theological thinkers in bioethics, Karen Lebacqz and Lisa Cahill, argue that theological discussions of justice broaden and deepen discussions of justice in mainstream bioethics—thus the focus on social justice provides an area for interdisciplinary and intersectional work; (2) pastoral theologians have not, to a great extent, contributed to discussions of religion and bioethics—this has been the territory of theological ethicists, especially during the 1970s; (3) one influential pastoral theologian, Bonnie Miller-McLemore, has called for (a) a broader concern for health in pastoral theology beyond psychological health and (b) more disciplinary approaches within pastoral theology beyond psychology so as to attend to “the living human web”; and (4) one way to advance the theological contributions in bioethics is by inviting pastoral theologians to focus on matters of social justice (an established area of intersection) as identified by health professionals, thus providing (a) new areas for inquiry and (b) new theological perspectives in bioethics. This article also suggests that pastoral theologians can contribute to bioethics by focusing on both “macro” issues (issues relating to structures and groups) and “micro” issues (issues relating to persons and experiences) as a way of pursuing the topic of justice in bioethics. The bulk of this article focuses on “macro” issues, but, in closing, the author articulates how he has been addressing “micro” issues in his own work. The author argues that both of these approaches—“macro” and “micro”—are legitimate ways for pastoral theologians to express pastoral concerns in bioethics.     

Token Economies: Using Basic Experimental Research to Guide Practical Applications

This paper highlights the applicability of patterns seen within basic experimental research in relation to contemporary application of token economies. Token economies are one of the most widely used interventions to promote behavior change, and this procedure has evolved to be effective across many settings, behaviors, and individuals. Due to this widespread use, casual implementation of the token economy might result in inconsistencies in responding and therefore an overall skepticism in the procedure itself. We present multiple barriers that encumber practical application of token economies, including insufficient conditioning and pairing of tokens, determining quality of backup reinforcers, unforeseen effects of motivating operations, teaching the token exchange, effects of higher-order reinforcement schedules, ratio strain, and use of response cost procedures. To assist practitioners in implementing more effective treatments, for each barrier we revisit the often overlooked basic research involving features of conditioned reinforcement and reinforcement schedules. It is important to translate the often complex implications of basic research so that practitioners can use this information to improve their own practice as well as their confidence in disseminating use of this evidence-based treatment. To further guide practitioners in using this knowledge in everyday settings, we also provide recommendations specific to each barrier as well as relevant applied research and practical examples.     

Clinical and functional correlates of processing speed in pediatric Attention-Deficit/Hyperactivity Disorder: a systematic review and meta-analysis

It is well established that processing speed is negatively impacted in children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD). Unfortunately, exactly how processing speed vulnerabilities manifest in daily functioning has not been well established. To support clinical care of youth with ADHD, it is important to better understand the functional consequences and relevant outcomes associated with processing speed deficits. This systematic review and meta-analysis sought to identify the association between processing speed and clinical or functional correlates among children or adolescents diagnosed with ADHD. A total of 409 abstracts were screened, of which, 60 full-text articles were identified as potentially relevant, and 8 of these studies met inclusion criteria. Domains evaluated across these studies included reading skills, mathematics skills, written expression, anxiety, self-appraisals of competence, and adaptive functioning. Six studies reported an association between processing speed and reading skills, allowing for meta-analysis. Processing speed difficulties among youth with ADHD appear strongly associated with several clinical and functional correlates including weaker academic skills, poorer adaptive skills, increased self-reported anxiety, and overestimates of social competence. Meta-analytic results for studies reporting the association between processing speed and reading skills indicate a medium overall weighted mean effect size (r = 0.33, 95% CI = 0.28 –0.39) with minimal heterogeneity (I² = 0.17). Clinical implications of these findings, limitations in the current knowledge base, and suggestions for future research are discussed.     

Religious authority and the transmission of abstract god concepts

According to the Standard Model account of religion, religious concepts tend to conform to “minimally counterintuitive” schemas. Laypeople may, to varying degrees, verbally endorse the abstract doctrines taught by professional theologians. But, outside the Sunday school exam room, the implicit representations that tend to guide people’s everyday thinking, feeling, and behavior are about minimally counterintuitive entities. According to the Standard Model, these implicit representations are the essential thing to be explained by the cognitive science of religion (CSR). It is argued here that this theoretical orientation of mainstream CSR misses a whole dimension of religiosity—the acceptance of certain religious authorities, that is, the acceptance of other people’s superior expertise. Average believers (especially in doctrinal traditions) tend to accept the authority of religious experts who espouse highly counterintuitive ideas that they (the laypeople) understand in a distorted form, if at all. These highly counterintuitive ideas are culturally successful because laypeople see them as being justified by people they have reason to regard as epistemic authorities. The tendency for people to endorse (without fully understanding) highly counterintuitive religious ideas espoused by intellectuals may explain parallels in the development of separate traditions (e.g., Judaism and Hinduism), as religious philosophers follow parallel lines of reasoning.     

Posttraumatic stress severity is associated with coping motives for alcohol use among in-patient and community recruited adolescents

Background and Objectives: A growing body of work suggests individuals with more severe post-traumatic stress symptoms (PTSS) are at higher risk for developing problematic alcohol use outcomes. Extending work from the adult literature, the present study was the first to examine the extent to which PTSS is related to drinking motives for alcohol use in both clinical and non-clinical samples of adolescents.

Design: Hierarchical regression analyses were used to predict coping motives for alcohol use from PTSS, above and beyond demographic variables, alcohol use frequency, and other alcohol use motives.

Methods: Trauma-exposed adolescents before entering treatment (Sample 1 n?=?41) and recruited from the local community (Sample 2 n?=?55) self-reported on PTSS and alcohol use motives.

Results: PTSS positively predicted coping motives for alcohol use after controlling for age, gender, and alcohol use frequency.

Conclusions: The current study highlights the need to consider both PTSS severity, as well as underlying cognitive mechanisms (e.g., motives), to better understand the etiology of problematic alcohol use among trauma-exposed youth. Future work focused on clarifying the trajectory of alcohol use motives and problems as a function of PTSS is needed.     

Aspects of identity: From the inner-outer metaphor to a tetrapartite model of the self

Abstract

We review a program of research on identity orientations – the relative importance or value that individuals place on various identity attributes when constructing their self-definitions. We first provide a brief history of the development of our measure of identity orientations – the Aspects of Identity Questionnaire (AIQ) – after which we present our tetrapartite model of the self that distinguishes among individual, relational, public, and collective aspects of identity. We then review previous research on how the four identity orientations uniquely influence cognition, emotion, and behavior, and close by highlighting what we see as interesting and important directions for future research.     

Bayes factors for the linear ballistic accumulator model of decision-making

Evidence accumulation models of decision-making have led to advances in several different areas of psychology. These models provide a way to integrate response time and accuracy data, and to describe performance in terms of latent cognitive processes. Testing important psychological hypotheses using cognitive models requires a method to make inferences about different versions of the models which assume different parameters to cause observed effects. The task of model-based inference using noisy data is difficult, and has proven especially problematic with current model selection methods based on parameter estimation. We provide a method for computing Bayes factors through Monte-Carlo integration for the linear ballistic accumulator (LBA; Brown and Heathcote, 2008), a widely used evidence accumulation model. Bayes factors are used frequently for inference with simpler statistical models, and they do not require parameter estimation. In order to overcome the computational burden of estimating Bayes factors via brute force integration, we exploit general purpose graphical processing units; we provide free code for this. This approach allows estimation of Bayes factors via Monte-Carlo integration within a practical time frame. We demonstrate the method using both simulated and real data. We investigate the stability of the Monte-Carlo approximation, and the LBA’s inferential properties, in simulation studies.
