Three experiments investigated people's motivation to conserve the self's limited regulatory resource after it is depleted by initial self-control exertion. Across the experiments, the results supported the idea of a conservation process. In Experiment 1, depleted participants' subsequent performance decreased when expecting to engage in a future self-regulation task compared to engaging in no task at all. In Experiments 2 and 3 we employed the “end-effect” pattern found in past vigilance research to further examine conservation. In Experiment 2, depleted and nondepleted participants who knew the study ran for 30 min performed similarly following 20 min of self-regulation, whereas 3 min or 10 min of self-regulation produced typical depletion effects. Likewise, the findings from Experiment 3 revealed this same conservation pattern using a shortened 6-min initial task. Specifically, when depleted participants believed the study was finished their task performance was better compared to those who believed the study would run for another 20 min. In short, the current findings support the idea of conservation—decrements in self-regulatory performance may represent an adaptive inclination to conserve the self's diminished resources rather than an inability to wield further self-control. 相似文献

Psychotherapy can no longer be understood as a morally neutral or value-free practice. Many have argued that psychology is implicitly and inevitably laden with moral assumptions and has a significant impact on the moral and ethical fabric of its clients and surrounding society (Browning 1987; Doherty 1995; Dueck and Reimer 2003; Kelly and Strupp 1992; Rieff 1987, 2006). In this work, the authors highlight the profound identity crises within the field of psychology around the place of morality/ethics in its theories and practices. Chronicling some of the shifts between modern and postmodern theory will allow for a meaningful engagement with this issue. The postmodern shifts in the field have left clinicians ideologically hampered in their ability to attend to the moral dimensions of their clients’ lives. In conclusion, the authors posit a virtue ethics and consider avenues of holistically and meaningfully infusing clinical practice with moral sensibilities. 相似文献

A multiple group confirmatory factor analysis was used to test the invariance of an attention-deficit/hyperactivity disorder-inattention, attention-deficit/hyperactivity disorder-hyperactivity/impulsivity, oppositional defiant disorder toward adults, academic and social competence five-factor model across of independent groups of Thai adolescents with the Child and Adolescent Disruptive Behavior Inventory (CADBI). Mothers and fathers’ ratings on 872 adolescents were compared to mothers and fathers’ ratings on a different group of 983 adolescents. The design allowed four invariance analyses (i.e., mothers’ ratings of the first group compared to mothers’ ratings of the second group; fathers’ ratings of first group compared to fathers’ ratings of the second group; mothers’ ratings of first group compared to fathers’ ratings of the second group; and fathers’ ratings of first group compared to mothers’ ratings of second group). Support was found for the invariance of like-symptom loadings and symptom intercepts as well as like-factor variances, covariances, and factor means across the four invariance analyses. The findings further expand the construct validity of the CADBI. The paper also introduces a multiple indicators by multiple traits by multiple methods by multiple sources by multiple occasions by multiple groups’ measurement matrix to guide the evaluation of the construct validity of ADHD/ODD rating scales. 相似文献

OBJECTIVE: Previous work suggests that elevated trait anger-out exacerbates pain responses in part through endogenous opioid dysfunction. The authors examined whether this opioid dysfunction affects not only perceived pain intensity, but also emotional responses to being hurt. DESIGN: 79 chronic low back pain (LBP) patients and 46 healthy controls received opioid blockade (8 mg naloxone i.v.) and placebo in randomized, counterbalanced order in separate sessions. During each session, participants sequentially experienced finger pressure pain and ischemic forearm pain tasks, with emotional state assessed at baseline and postpain. MAIN OUTCOME MEASURES: Blockade effects indexing opioid modulation of emotional reactivity were derived by subtracting placebo from blockade condition emotional reactivity. RESULTS: Significant Participant Type x Anger-Out interactions on blockade effects indicated that in LBP participants but not in controls, greater anger-out was associated with deficient opioid modulation of anxiety, anger, and fear reactivity to noxious stimulation. Across participant types, greater anger-in was associated with impaired opioid modulation of anxiety and fear reactivity. Anger-in opioid effects were partially due to overlap with general negative affect. CONCLUSIONS: Opioid dysfunction associated with trait anger-out may affect not only perceived pain intensity, but also pain-related suffering in individuals with chronic pain conditions. Implications for understanding the health effects of anger management styles are discussed. 相似文献

Theories of skill acquisition have made radically different predictions about the role of general problem-solving methods in acquiring rules that promote effective transfer to new problems. Under one view, methods that focus on reaching specific goals, such as means-ends analysis, are assumed to provide the basis for efficient knowledge compilation (Anderson, 1987), whereas under an alternative view such methods are believed to disrupt rule induction (Sweller, 1988). We suggest that the role of general methods in learning varies with both the specificity of the problem solver's goal and the systematicity of the strategies used for testing hypotheses about rules. In the absence of a specific goal people are more likely to use a rule-induction learning strategy, whereas provision of a specific goal fosters use of difference reduction, which tends to be a non-rule-induction strategy. We performed two experiments to investigate the impact of goal specificity and systematicity of rule-induction strategies in learning and transfer within a complex dynamic system. The results of Experiment 1 indicated that during free exploration of a problem space, greater learning occurred if participants adopted more systematic strategies for rule induction, and that participants come to favor such strategies. Experiment 2 revealed that participants who were provided with a specific goal performed well on the initial problem but were impaired on a transfer test using a similar problem with a different goal. Instruction on a systematic rule-induction strategy facilitated solution for both the initial and transfer problems, but participants' use of this strategy declined if they had a specific goal. Our results support Sweller's (1988) proposal that general problemsolving methods applied to a specific goal foster acquisition of knowledge about an isolated solution path but do not provide an effective way of learning the overall structure of a problem space. We interpret these results in terms of dualspace theories of search through problem space. 相似文献
