Upward counterfactual thoughts identify how a prior outcome could have been better and have been shown to improve subsequent performance. Both the identification of corrective actions (content-specific effects) and the more general mobilization of effort as a result of negative affect (content-neutral effects) have been suggested to underlie performance benefits. The results of three experiments presented here indicate that counterfactual thoughts have broad benefits for performance, independent of their content and beyond the effects of planning. These benefits were consistently dependent upon the experience of negative affect, but were eliminated when negative affect could be (mis)attributed to an intervening task. This misattribution effect is consistent with the operation of a mood-as-input process in which affect informs judgments of goal progress. Overall, the findings suggest that the benefits of upward counterfactual thinking reflect more broad attempts to improve following a subjectively unsatisfactory performance.  相似文献

In two studies (N’s = 57 and 115), we demonstrate that type of perspective-taking instruction (“imagine self” vs. “imagine other”) differentially affects two motives for helping: self-other overlap and empathic concern. Imagine-self instructions produce greater self-other overlap than imagine-target and objective instructions, while both types of perspective-taking instruction promote empathic concern relative to an objective condition. In Study 2, imagine-self instructions indirectly increased the likelihood of helping via empathic concern and self-other overlap, while imagine-target instructions led indirectly to greater helping only through empathic concern. We discuss how different perspective-taking instructions may implicate different emotional and motivational paths to increasing helping.  相似文献

Successfully explaining and replicating the complexity and generality of human and animal learning will require the integration of a variety of learning mechanisms. Here, we introduce a computational model which integrates associative learning (AL) and reinforcement learning (RL). We contrast the integrated model with standalone AL and RL models in three simulation studies. First, a synthetic grid‐navigation task is employed to highlight performance advantages for the integrated model in an environment where the reward structure is both diverse and dynamic. The second and third simulations contrast the performances of the three models in behavioral experiments, demonstrating advantages for the integrated model in accounting for behavioral data.  相似文献

Purpose

The purpose of this study was to develop and test a model relating proactive personality to job behaviors (task and citizenship behaviors) through the intervening mediator of perceived role breadth.

Design/methodology/approach

Survey data were obtained from 530 faculty members in 69 U. S. research universities.

Findings

Proactive personality was positively related to task behavior and OCB. Perceived role breadth mediated the relationship between proactive personality and OCB, but did not mediate the relationship between proactive personality and task behavior. Despite not viewing their role more broadly, individuals higher in proactive personality engaged more frequently in both task behavior and OCB; and also worked more hours per week.

Implications

Having a better understanding of proactive individuals is important in terms of managing them. Because these individuals tend to do more in their jobs and subsequently work more hours, they may be more susceptible to burnout and may require additional help in determining priorities and balancing their work and lives.

Originality/value

This is the first study to show that proactive personality is positively related to the frequency with which these individuals engage in task and citizenship behavior. Although role breadth is generally an antecedent of such job behaviors, individuals higher in proactive personality engage more frequently in task behaviors regardless of whether or not they perceive them as part of their role. This is one of the first studies to show that working more hours each week is a potential cost of having a proactive personality.  相似文献

Leader affective presence is the tendency of leaders to elicit feelings that are consistent among other individuals, and has been supported as a relevant personality trait for understanding teamwork. Drawing on a model that integrates personality and emotion regulation, this study aimed to expand research on affective presence by proposing team members’ perceptions of leader interpersonal emotion regulation as a process that explains how leader affective presence is related to team member behaviour. In the model, teamness—the perception that interdependence and reflexivity are required in the team—is presented as a boundary condition to the effects of affective presence via emotion regulation. Results of a study conducted with 99 teams showed that team member ratings of leader positive affective presence were linked to their perceptions that leaders had used affect-improving emotion regulation which in turn was associated with greater team citizenship behaviour. Contrariwise, team member ratings of leader negative affective presence were associated with perceived use of affect-worsening emotion regulation by leaders which in turn was associated with lower levels of team citizenship, but only when teams were low in teamness. These findings contribute to understanding how leaders’ individual differences are related to teamwork through affective processes.  相似文献

The alpha-2 adrenergic receptor antagonist, yohimbine, can facilitate fear extinction in animals and humans. One potential mechanism is increased noradrenergic activity and associated arousal in the presence of conditioned stimuli. Accordingly, yohimbine might augment prolonged exposure (PE) therapy for posttraumatic stress disorder (PTSD), where heightened exposure-oriented arousal is a theorized driver and empirical predictor of treatment success. A double-blind placebo-controlled randomized trial (NCT 01031979) piloted yohimbine augmentation in 26 males with combat-related PTSD. Participants were given one-time dose of yohimbine or placebo prior to the first imaginal exposure. Subsequently, both arms completed standard PE. The primary outcome was trauma-cued heart-rate reactivity a week after the drug/exposure visit, a highly specified, objective measure sensitive to incremental change. Secondary outcomes included arousal during the drug/exposure visit and slope of distress, PTSD, and depression over the course of PE. Consistent with hypothesis, yohimbine led to higher objective and subjective arousal during the drug/exposure visit and to lower trauma-cued heart-rate reactivity one-week later. One dose of yohimbine also led to greater between-session habituation and more rapid improvement on depression, but not PTSD, over the course of care. Results of this controlled pilot indicate support for continued investigation of yohimbine-augmented exposure therapy for PTSD.  相似文献

Cognitive-behavioral therapy (CBT), consisting of exposure and response prevention (EX/RP), is both efficacious and preferred by patients with obsessive–compulsive disorder (OCD), yet few receive this treatment in practice. This study describes the implementation of an Internet-based CBT program (ICBT) developed in Sweden in individuals seeking OCD treatment in New York. After translating and adapting the Swedish ICBT for OCD, we conducted an open trial with 40 adults with OCD. Using the RE-AIM implementation science framework, we assessed the acceptability, feasibility, and effectiveness of ICBT. The Yale–Brown Obsessive Compulsive Scale (Y-BOCS) was the primary outcome measure. Of 40 enrolled, 28 participants completed the 10-week ICBT. In the intent-to-treat sample (N = 40), Y-BOCS scores decreased significantly over time (F = 28.12, df = 2, 49, p < . 001). Depressive severity (F = 5.87, df = 2, 48, p < . 001), and quality of life (F = 12.34, df = 2, 48, p < . 001) also improved. Sensitivity analyses among treatment completers (N = 28) confirmed the intent-to-treat results, with a large effect size for Y-BOCS change (Cohen’s d = 1.38). ICBT took less time to implement than face-to face EX/RP and participants were very to mostly satisfied with ICBT. On a par with results in Sweden, the adapted ICBT program reduced OCD and depressive symptoms and improved quality of life among individuals with moderate to severe OCD. Given its acceptability and feasibility, ICBT deserves further study as a way to increase access to CBT for OCD in the United States.  相似文献
