合作与利己是利益冲突情境中个体的基本行为模式。在理性假设所主导的框架下,利己行为被看作是人类的本能反应。然而,近期的观点指出,人类的合作本质上是一种自动化的行为反应。无意识、认知能力、自我损耗以及神经科学等领域的理论和研究支持像合作这样复杂的社会行为可以自动地激活。未来研究除了需要继续揭示行为自动化的结果是利己还是利他之外,还需要确定社会合作自动化产生的机制与条件。  相似文献

教育心理学领域的不流畅效应认为,学习难读材料要比学习易读材料的效果更好。已有研究主要通过操纵学习材料中的文本、画面或声音属性考察知觉流畅性在学习过程中的作用,并发现不流畅材料可能有助于缓解过度自信现象,但不一定能提高学习效果,不流畅效应的稳健性受到质疑。合理难度理论与不流畅理论均认为,知觉不流畅所引发的额外认知负荷促进了学习;相反,认知负荷理论认为这种额外认知负荷会阻碍学习。对现有研究进行元分析,结果表明,知觉不流畅既降低了学习判断的自信心(d=-0.54),也不利于提高学习效果(d=-0.36),一定程度上支持认知负荷理论。未来研究需关注知觉流畅性本身的操纵、界限及系统性评定,并探讨不流畅效应的边界条件等。  相似文献

There has recently been much interest in computerized adaptive testing (CAT) for cognitive diagnosis. While there exist various item selection criteria and different asymptotically optimal designs, these are mostly constructed based on the asymptotic theory assuming the test length goes to infinity. In practice, with limited test lengths, the desired asymptotic optimality may not always apply, and there are few studies in the literature concerning the optimal design of finite items. Related questions, such as how many items we need in order to be able to identify the attribute pattern of an examinee and what types of initial items provide the optimal classification results, are still open. This paper aims to answer these questions by providing non‐asymptotic theory of the optimal selection of initial items in cognitive diagnostic CAT. In particular, for the optimal design, we provide necessary and sufficient conditions for the Q ‐matrix structure of the initial items. The theoretical development is suitable for a general family of cognitive diagnostic models. The results not only provide a guideline for the design of optimal item selection procedures, but also may be applied to guide item bank construction.  相似文献

The present study examined cognitive distortions of child molesters on probation or parole in Japan utilizing an 18‐item questionnaire administered in a treatment program conducted by the probation officers. This study analyzed the responses of child molesters (n = 51), non‐child‐molesting sexual offenders (n = 65), and non‐offenders (n = 64). Factor analysis of the responses showed three types of cognitive distortions: Rationalization of Offending Behavior, Minimization of Responsibility for Offending, and Minimization of Victim Harm. Welch's analysis of variance followed by Games‐Howell post hoc tests revealed that the child molesters scored significantly higher than the non‐offender group on the Rationalization of Offending Behavior subscale and the Minimization of Responsibility for Offending subscale, and significantly higher than the non‐child‐molesting sexual offender group on the Minimization of Responsibility for Offending subscale. The authors discuss the meanings of these three types of cognitive distortions and future research issues.  相似文献

Assisted reproductive technologies (ART) lack biological filters that are part of the natural fertilization process and thus might enable the presence of abnormal genetic materials. Whereas the findings regarding neonatal and neurological risks among ART-conceived children are rather consistent, data regarding cognitive and social-emotional developmental outcomes are inconsistent. The aim of this study was to examine the association between ART and cognitive and social-communication outcomes among pre-school children. The results indicated that the cognitive and social-communicative abilities of the ART-conceived children were similar to those of the spontaneously conceived children; however, according to parental reports, children in the ART group had higher communicative skills and better motor abilities than spontaneously conceived children. These results should be interpreted with caution as we used measures that assess global cognitive abilities that may not be sensitive to more subtle differences of higher cognitive and social-communication abilities in infancy that may become more prominent later in life. Although infertile couples and professionals in the field of ART can be reassures by the current findings, further research is needed as well as follow-up evaluation of this population during school age.  相似文献

Of the many vulnerable groups affected by the spread of COVID-19, veterans have been especially impacted by the pandemic. Beginning in March 2020, nationwide shelter-in-place orders rapidly led to widespread job loss and economic upheaval; disruption and breakdown of multiple support systems; and increases in family stress, all of which may exacerbate underlying PTSD symptoms. Although telehealth has proven an effective means of delivering evidence-based psychotherapies for PTSD, little is known about the delivery of these treatments in an intensive, daily format over telehealth. There is growing need for intensive treatment options to reduce treatment-interfering barriers such as high dropout rates. In order to address this gap in the literature, this paper details several design considerations as well as patient selection procedures for a 2-week virtual intensive treatment program (vITP) for veterans with posttraumatic stress disorder (PTSD), consisting of daily individual Cognitive Processing Therapy (CPT) and other adjunctive interventions. We also describe two cases of veterans who successfully completed the vITP including their clinical outcomes, therapist reflections on the process, feedback regarding the program, as well as challenges patients encountered with the telehealth platform. Intensive evidence-based psychotherapy for PTSD delivered through a virtual format seems to show promise, but more systemic research is needed.  相似文献

Rule‐guided behavior depends on the ability to strategically update and act on content held in working memory. Proactive and reactive control strategies were contrasted across two experiments using an adapted input/output gating paradigm (Neuron, 81, 2014 and 930). Behavioral accuracies of 3‐, 5‐, and 7‐year‐olds were higher when a contextual cue appeared at the beginning of the task (input gating) rather than at the end (output gating). This finding supports prior work in older children, suggesting that children are better when input gating but rely on the more effortful output gating strategy for goal‐oriented action selection (Cognition, 155, 2016 and 8). A manipulation was added to investigate whether children's use of working memory strategies becomes more flexible when task goals are specified internally rather than externally provided by the experimenter. A shift toward more proactive control was observed when children chose the task goal among two alternatives. Scan path analyses of saccadic eye movement indicated that giving children agency and choice over the task goal resulted in less use of a reactive strategy than when the goal was determined by the experimenter.  相似文献

ABSTRACT

Mild functional difficulties associated with cognitive aging may be reliably measured by coding “micro-errors” during everyday tasks, like meal preparation. Micro-errors made by 25 older adult and 48 younger adults were coded on four dimensions to evaluate the influence of: 1) poor error monitoring; 2) goal decay; 3) competition for response selection when switching to a new subtask; and 4) interference from distractor objects. Micro-errors made by young adults under a dual task load also were analyzed to determine the influence of overall performance level. Older adults’ micro-errors were observed when switching to a new subtask and to unrelated distractors. Slowed error monitoring and goal decay also influenced micro-errors in older adults, but not significantly more so than younger adults under the dual task. Interventions to reduce interference from distractors and to increase attention at critical choice points during tasks may optimize everyday functioning and preclude decline in older adults.  相似文献

如何提升团队创新绩效?这是近年来管理实践界与学术界共同关注的热门话题。鉴于创新是一项兼具“探索”与“利用”双元特征的活动, 懂得如何平衡二者之间的悖论关系就成为提升团队创新绩效的关键。基于成员认知风格的微观视角, 从“组型”与“构型”两方面探索了解决这一悖论关系的方法。具体而言:(1)成员认知风格组型与团队领导行为之间的互补效应有助于解决团队创新悖论; (2)在合理的“成员认知风格-工作角色要求”构型基础上, 营造良好的团队协作氛围, 有助于解决团队创新悖论。进一步地, 还基于阴阳哲学思想研究了解决团队创新悖论的内在机制。为论证相关理论命题, 将开展三个研究模块, 采用定量与定性相结合的研究方法对提出的研究模型进行检验。相关发现不仅有助于丰富从微观视角研究团队创新前因、悖论管理方法的理论成果, 还将为企业的创新管理实践提供建议。  相似文献

The emotional valence of memory recall strongly influences the extreme, and often self‐destructive behavioral response. Overall, 4427 people from the community filled out our screening questionnaire, of which 674 (mean age: 32.9 years, 64.7% women) passed the threshold for the likely presence of borderline personality disorder (BPD). Participants watched one of 9 possible video clips differing in valence (positive, negative or neutral). Results indicate support (ß = .151, p < .05) for a negative cognitive tendency in the evaluations proportionate to the severity of BPD but only when the impression is assessed with negatively‐worded items. This effect is detectable regardless of other factors such as negative mood, extremity of the answers or general impression of the character. These effects are unaffected by acute trauma. To conclude, different factors influence the recall of emotional stimuli, depending on the valence of the stimuli and the valence of the rating scale in persons with strong borderline tendencies.  相似文献
