Recently, Martin and Dahlen (J Ration Emot Cogn Behav Ther 25:155–173, 2007) developed the Angry Cognitions Scale (ACS), a theoretically derived instrument designed to measure the cognitive processes
related to anger. This instrument has the potential to inform clinical and research perspectives of anger. Although preliminary
evidence for the reliability and validity of the ACS was positive, further research is required regarding the ACS’s temporal
stability and predictive validity. The current project sought to address this concern by assessing the six-week test–retest
reliability of the ACS, exploring relationships between the ACS subscales and the experience and expression of anger, and
assessing the ability of the ACS to predict cognitive and emotional responses to provocation. The ACS demonstrated adequate
test–retest reliability and predicted hostile thoughts and state anger following provocation. Thus, results contribute to
the literature on the ACS and support its use as a measure of cognitive processes associated with anger. 相似文献

This study adopted a developmental perspective on recovery from conflict in romantic relationships. Participants were 73 young adults (target participants), studied since birth, and their romantic partners. A novel observational coding scheme was used to evaluate each participant's degree of conflict recovery, operationalized as the extent to which the participant disengaged from conflict during a 4-min "cool-down" task immediately following a 10-min conflict discussion. Conflict recovery was systematically associated with developmental and dyadic processes. Targets who were rated as securely attached more times in infancy recovered from conflict better, as did their romantic partners. Concurrently, having a romantic partner who displayed better recovery predicted more positive relationship emotions and greater relationship satisfaction. Prospectively, target participants' early attachment security and their partners' degree of conflict recovery interacted to predict relationship stability 2 years later, such that having a partner who recovered from conflict better buffered targets with insecure histories. 相似文献

The recent report of the AMA Council on Ethical and Judicial Affairs (CEJA), "Professionalism in the Use of Social Media," describes the types of social media medical professionals use, outlines ways in which existing AMA policies address issues of online professionalism, and makes a list of recommendations for physicians to maintain online professionalism. CEJA recommends directed efforts towards educating physicians about the benefits and pitfalls of social media and, in particular, underscores the difficulties of maintaining professional boundaries in the digital age. In this commentary, we highlight issues introduced by the report and suggest some specific ways that the recommendations of the committee can be implemented by medical schools, residency programs, and practicing physicians. 相似文献

Recent studies lead to the paradoxical conclusion that the act of affirming one's egalitarian or pro-social values and virtues might subsequently facilitate prejudiced or self-serving behavior, an effect previously referred to as "moral credentialing." The present study extends this paradox to the domain of academic misconduct and investigates the hypothesis that such an effect might be limited by the extent to which misbehavior is rationalizable. Using a paradigm designed to investigate deliberative and rationalized forms of cheating (von Hippel, Lakin, & Shakarchi, 2005), we found that when participants had credentialed themselves (versus a non-close acquaintance) via a set of hypothetical moral dilemmas, they were more likely to cheat on a subsequent math task, but only if cheating was highly rationalizable. When cheating was difficult to rationalize, moral credentialing had almost no impact on cheating. 相似文献

Can conscious awareness be ascertained from physiological responses alone? We evaluate a novel learning-based procedure permitting detection of conscious awareness without reliance on language comprehension or behavioural responses. The method exploits a situation whereby only consciously detected violations of an expectation alter skin conductance responses (SCRs). Thirty participants listened to sequences of piano notes that, without their being told, predicted a pleasant fanfare or an aversive noise according to an abstract rule. Stimuli were presented without distraction (attended), or while distracted by a visual task to remove awareness of the rule (unattended). A test phase included occasional violations of the rule. Only participants attending the sounds reported awareness of violations and only they showed significantly greater SCR for noise occurring in violation, vs. accordance, with the rule. Our results establish theoretically significant dissociations between conscious and unconscious processing and furnish new opportunities for clinical assessment of residual consciousness in patient populations. 相似文献

The anterior thalamic nuclei (ATN) are important for learning and memory as damage to this region produces a persistent amnestic syndrome. Dense connections between the ATN and the hippocampus exist, and importantly, damage to the ATN can impair hippocampal functioning. Acetylcholine (ACh) is a key neurotransmitter in the hippocampus, and in vivo measures of ACh are correlated to learning and memory performance. In the present study, complete lesions of the ATN impaired performance on two measures of hippocampal-dependent learning and memory (spontaneous alternation and delayed alternation) and severely disrupted behaviorally evoked ACh efflux within the hippocampus of adult male rats. In contrast, incomplete ATN lesions did not impair spontaneous alternation performance but did impair delayed alternation performance while blunting hippocampal ACh efflux. Interestingly, ATN lesions of any size did not affect basal concentrations of ACh in the hippocampus. These results demonstrate that the ATN have the capacity to modulate behaviorally relevant neuronal transmission within the hippocampus. 相似文献

Visual short-term memory plays a key role in guiding behavior, and individual differences in visual short-term memory capacity
are strongly predictive of higher cognitive abilities. To provide a broader evolutionary context for understanding this memory
system, we directly compared the behavior of pigeons and humans on a change detection task. Although pigeons had a lower storage
capacity and a higher lapse rate than humans, both species stored multiple items in short-term memory and conformed to the
same basic performance model. Thus, despite their very different evolutionary histories and neural architectures, pigeons
and humans have functionally similar visual short-term memory systems, suggesting that the functional properties of visual
short-term memory are subject to similar selective pressures across these distant species. 相似文献

It has been suggested that the well-known health benefits associated with exercise can be explained by a placebo effect, and that greater effort should be given to convince people that their current behaviors have desirable health consequences. The overall purpose of this study was to test the efficacy of this "mind-set matters" hypothesis through the use of an expectancy-based intervention with adolescents. The study involved a four week randomized controlled trial with 348 Grade 9 adolescents (M (age)?=?14.07 yrs, SD?=?0.30), from four high schools, taking part in either a placebo-intervention condition (n?=?188) or a control condition (n?=?160). Participants in the placebo-intervention condition were informed that what they are already doing in school physical education lessons fulfills current recommendations for an active lifestyle. Participants in the control condition were not given this information. Four weeks after the intervention, adolescents in the placebo-intervention condition did not demonstrate significant changes in physiological health-related measures (diet, weight, body mass index, percentage body fat, heart rate, mean arterial pressure). The findings question the external validity of the "mind-set matters" hypothesis with adolescents, and suggest that simply encouraging adolescents to believe that they are healthy may not enable them to respond with improved indicators of physical health. 相似文献

“Ideas are like species: they must evolve.” This claim forms the conceptual core of an engaging book by Jonnie Hughes (2011), On the Origin of Tepees. Hughes asks: If evolution by natural selection explains the origin of the human species, then does selection by consequences also explain the origin of what we humans make and do? This question prompts consideration of three important analogies: between natural selection and artificial selection, between the law of natural selection and the law of effect, and between biological evolution and cultural evolution. These analogies in turn stimulate examination of the notions of purpose, design, and agency. Finally, discussion moves to the selectionism of Darwin and Skinner; although still controversial, this view remains the best way for natural science to understand the origins of adaptive behavior. 相似文献
