When do people cooperate? The neuroeconomics of prosocial decision making

Understanding the roots of prosocial behavior is an interdisciplinary research endeavor that has generated an abundance of empirical data across many disciplines. This review integrates research findings from different fields into a novel theoretical framework that can account for when prosocial behavior is likely to occur. Specifically, we propose that the motivation to cooperate (or not), generated by the reward system in the brain (extending from the striatum to the ventromedial prefrontal cortex), is modulated by two neural networks: a cognitive control system (centered on the lateral prefrontal cortex) that processes extrinsic cooperative incentives, and/or a social cognition system (including the temporo-parietal junction, the medial prefrontal cortex and the amygdala) that processes trust and/or threat signals. The independent modulatory influence of incentives and trust on the decision to cooperate is substantiated by a growing body of neuroimaging data and reconciles the apparent paradox between economic versus social rationality in the literature, suggesting that we are in fact wired for both. Furthermore, the theoretical framework can account for substantial behavioral heterogeneity in prosocial behavior. Based on the existing data, we postulate that self-regarding individuals (who are more likely to adopt an economically rational strategy) are more responsive to extrinsic cooperative incentives and therefore rely relatively more on cognitive control to make (un)cooperative decisions, whereas other-regarding individuals (who are more likely to adopt a socially rational strategy) are more sensitive to trust signals to avoid betrayal and recruit relatively more brain activity in the social cognition system. Several additional hypotheses with respect to the neural roots of social preferences are derived from the model and suggested for future research.     

The influence of discrete emotions on judgement and decision-making: a meta-analytic review

During the past three decades, researchers interested in emotions and cognition have attempted to understand the relationship that affect and emotions have with cognitive outcomes such as judgement and decision-making. Recent research has revealed the importance of examining more discrete emotions, showing that same-valence emotions (e.g., anger and fear) differentially impact judgement and decision-making outcomes. Narrative reviews of the literature (Lerner & Tiedens, 2006 ; Pham, 2007 ) have identified some under-researched topics, but provide a limited synthesis of findings. The purpose of this study was to review the research examining the influence of discrete emotions on judgement and decision-making outcomes and provide an assessment of the observed effects using a meta-analytic approach. Results, overall, show that discrete emotions have moderate to large effects on judgement and decision-making outcomes. However, moderator analyses revealed differential effects for study-design characteristics and emotion-manipulation characteristics by emotion type. Implications are discussed.     

Perceived support for mentoring: A multiple perspectives approach

Two studies were conducted to examine how perceptions of support for mentoring relate to mentoring attitudes and outcomes for both protégés and mentors, over and above established predictors. In study 1, protégés provided information on their perceptions of support for mentoring and mentoring received. As expected, perceived management support for mentoring was positively related to career-related and psychosocial support; and perceived mentor accountability for mentoring was negatively related to mentoring problems. In study 2, we examined mentors’ perceptions of support for mentoring in relation to their willingness to mentor others in the future and the extent to which they viewed their current relationship as complementary. Mentors’ perceptions of management support for mentoring were positively related to their belief that mentoring relationships were mutually beneficial. However, consistent with theories of self-determination, as mentors’ perceptions of their own accountability in the relationship increased their willingness to mentor others in the future decreased. Implications for mentoring theory, future research, and applied practice are discussed.     

The effects of workload history on dual task performance

The purpose of this study was to examine the effects of workload history (specifically sudden workload shifts) on performance. A sample of 204 undergraduates was randomly assigned to either a sudden decrease or increase in workload condition. Participants simultaneously performed a memory search task (i.e., primary task) and an auditory vigilance task (i.e., distracter task), while percent correct was recorded. Separate Repeated Measures ANOVA’s revealed a significant treatment effect for the Medium to Low (F(l, 110) = 274.6, p < .01) and Low to Medium (F(l,92) = 148.3, p < .01) conditions. Results supported previous research suggesting that either a sudden decrease (Medium to Low) or increase (Low to Medium) in workload could be detrimental to performance (Cox-Fuenzalida, 2000). More importantly, this study extends the detrimental effects of workload history to a dual task environment. The authors express their gratitude to the research team from the Personality and Human Performance Lab at the University of Oklahoma for their invaluable assistance in data planning and collection.     

Ego Integrity in the Lives of Older Women: A Follow-Up of Mothers From the Sears,Maccoby, and Levin (1951) Patterns of Child Rearing Study

Ego integrity, Erik Erikson's (E. H. Erikson, 1963) concept of psychological maturity in later life and the pinnacle of 8 stages, has been one of the least studied of all his stage constructs. This paper explores the meaning of ego integrity (as assessed by C. D. Ryff & S. G. Heincke, 1983) in the lives of a sample of older women, by examining the predictors and concomitants of ego integrity (EI), using data from interviews conducted with the same women in 1951 and 1996 and a questionnaire administered in 1996. A 3-step regression model revealed that “identity” assessed in 1951 predicted generativity in 1996; the level of educational attainment and marital status were also significant predictors. In step 2, generativity alone predicted ego integrity, which in turn predicted depression. Ego integrity was associated with higher marital satisfaction in the mothers' lives, both in the past and in the present; it was implicated in better relationships with their adult children, in the mothers' willingness to both give and receive help, and in several dimensions of psychological well-being.     

High self-control predicts good adjustment, less pathology, better grades, and interpersonal success

What good is self‐control? We incorporated a new measure of individual differences in self‐control into two large investigations of a broad spectrum of behaviors. The new scale showed good internal consistency and retest reliability. Higher scores on self‐control correlated with a higher grade point average, better adjustment (fewer reports of psychopathology, higher self‐esteem), less binge eating and alcohol abuse, better relationships and interpersonal skills, secure attachment, and more optimal emotional responses. Tests for curvilinearity failed to indicate any drawbacks of so‐called overcontrol, and the positive effects remained after controlling for social desirability. Low self‐control is thus a significant risk factor for a broad range of personal and interpersonal problems.
