Adopting a motivational perspective on creativity, we theorized when and how perceived cognitive diversity in teams was associated with creativity by focusing on the mediating role of intrinsic motivation and the moderating role of learning orientation. We further expanded our contribution by examining these relationships at both the individual and team levels. We used a sample of 382 Chinese employee–supervisor pairs nested within 106 teams to test our hypotheses. The results revealed that, at both the individual and team levels, learning goal orientation significantly moderated the positive association between perceived cognitive diversity and intrinsic motivation such that the latter relationship became stronger as learning goal orientation increased. Furthermore, our findings confirmed that learning goal orientation enhanced the indirect positive relationship between perceived cognitive diversity and creativity through intrinsic motivation. 相似文献

前瞻记忆意向后效应会对日常生活产生负面影响,研究发现这种现象在老年人中尤其突出。近些年来,研究者们从内外两方面对影响前瞻记忆意向后效应年龄差异的因素进行了探讨,了解到认知老化所带来的抑制能力的衰退以及短时记忆缺陷是造成其年龄差异的主要原因。未来研究需进一步拓展对认知老化的机制和抑制控制能力的认识。另外,可以采用事件相关电位(Event-Related Potentials, ERPs)和功能性磁共振成像(Functional Magnetic Resonance Imaging, fMRI)等脑成像技术揭示前瞻记忆意向后效应年龄差异的加工机制及神经机制。 相似文献

Performance on many decision‐making tasks is underpinned by metacognitive monitoring, cognitive abilities, and executive functioning. Fatigue‐inducing conditions, such as sleep loss, compromise these factors, leading to decline in decision performance. Using a 40‐hr sleep deprivation protocol, we examined these factors and the resulting decision performance. Thirteen Australian Army male volunteers (aged 20–30 years) were tested at multiple time points on psychomotor vigilance, inhibitory control, task switching, working memory, short‐term memory, fluid intelligence, and decision accuracy and confidence in a medical diagnosis‐making test. Assessment took place in the morning and night over two consecutive days, during which participants were kept awake. Consistent with previous work, cognitive performance declined after a night without sleep. Extending previous findings, self‐regulation and self‐monitoring suffered significantly greater declines immediately after the sleepless night. These results indicate that the known decline in complex decision‐making performance under fatigue‐inducing conditions might be facilitated by metacognitive rather than cognitive mechanisms. 相似文献

Sotos syndrome is a congenital overgrowth disorder, associated with intellectual disability. Previous research suggests that Sotos syndrome may be associated with relative strength in verbal ability and relative weakness in non-verbal reasoning ability but this has not been explicitly assessed. To date, the cognitive profile of Sotos syndrome is unknown. Cognitive abilities of a large and representative sample of individuals with Sotos syndrome (N = 52) were assessed using the British Ability Scales (BAS3). The majority of participants had intellectual disability or borderline intellectual functioning. The cluster score profile analysis revealed a consistent verbal ability > non-verbal reasoning ability profile. Four specific criteria were proposed as the Sotos syndrome cognitive profile (SSCP): verbal ability > non-verbal reasoning ability; quantitative reasoning T-score or matrices T-score <20th percentile; quantitative reasoning T-score < mean T-score; recognition of designs T-score or recognition of pictures T-score > mean T-score. Of the 35 participants included in the profile analysis, 28 met all four SSCP criteria, yielding a sensitivity of 0.8. The sensitivity of each of the SSCP criteria was >0.9. Individuals with Sotos syndrome display a clear and consistent cognitive profile, characterized by relative strength in verbal ability and visuospatial memory but relative weakness in non-verbal reasoning ability and quantitative reasoning. This has important implications for the education of individuals with Sotos syndrome. 相似文献

Evidence supporting the effectiveness of cognitive behavior therapy (CBT) for stress-related illness is growing, but little is known about its mechanisms of change. The aim of this study was to investigate potential mediators of CBT for severe stress in form of clinical burnout, using an active psychological treatment as comparator. We used linear mixed models to analyze data from patients (N = 82) with clinical burnout who received either CBT or another psychological treatment in a randomized controlled trial. Potential mediators (i.e., sleep quality, behavioral activation, perceived competence, and therapeutic alliance) and outcome (i.e., symptoms of burnout) were assessed weekly during treatment. The results showed that the positive treatment effects on symptoms of burnout favoring CBT (estimated between-group d = 0.93) were mediated by improvements in sleep quality, ab = -0.017, 95% CIasymmetric [-0.037, -0.002], and increase in perceived competence, ab = -0.037, 95% CIasymmetric [-0.070, -0.010]. Behavioral activation, ab = -0.004 [-0.016, 0.007], and therapeutic alliance, ab = 0.002 [-0.006, 0.011], did not significantly mediate the difference in effects between the treatments. Improving sleep quality and increasing perceived competence may thus constitute important process goals in order to attain symptom reduction in CBT for clinical burnout. 相似文献

There is a growing literature associating anxiety disorders with an inability to inhibit defensive responding during safety conditions of threatening tasks. However, investigations on the relation between panic disorder (PD) and defensive responding to safety have yielded mixed results. A recent study from our laboratory revealed that intolerance of uncertainty (IU) moderates this association, such that only individuals with PD and a high IU exhibit heightened startle potentiation during safety. The mechanism underlying this relationship is unknown. Given that safety conditions typically alternate with periods of threat, cognitive flexibility (i.e., the ability to adjust one's habitual responding to a situation, given the input of new information) may be involved in the ongoing reappraisal of danger and adjustment of defensive responding. Thus, the present study sought to investigate whether deficits in cognitive flexibility mediate the association between IU and defensive responding to safety among a sample of 71 adults diagnosed with PD. As hypothesised, cognitive flexibility mediated the relationship between IU and heightened startle potentiation during safety conditions. This finding suggests that within this subgroup, a failure to inhibit defensive responding during safety conditions may be due to deficits in cognitive flexibility. 相似文献

The Western mental health profession has included Buddhist practices in its clinical applications, and Buddhisms’ contribution to mindfulness-based interventions (MBIs) could be considered as one of its main inputs. However, MBIs appear to depart in some key ways from their Buddhist origins whereby it may reduce its psychotherapeutic value and affect the accurate dissemination of the Buddhas’ teachings. This paper reflects on some of these departures, by firstly discussing the term mindfulness, which, as used in the MBIs, has a more restrictive meaning than that meant by the Buddha. Secondly, this paper discusses the usefulness of MBI therapists being knowledgeable in a range of meditation techniques, rather than in only a few. And thirdly, this paper discusses the usefulness of MBI therapists having a personal mindfulness practice of ones’ own, and concludes by suggesting that an explicit acknowledgement of the Buddha in the formation of the MBIs be considered. 相似文献

This study examined the impact of thought suppression on the quality of cognitive processing and self-reported mood. While completing a stream-of-consciousness task about two topics sequentially, participants were either instructed to suppress negative thoughts or were given no suppression instructions. Computer-based content analyses indicated that thought suppression led to significantly less causal reasoning and discrepancy seeking. However, the suppression of negative thoughts also resulted in a more positive mood. Results suggest that thought suppression can improve mood but it comes with the cognitive cost of superficial processing. 相似文献

第二语言水平对双语者语言抑制能力的影响——来自英语–汉语单通道双语者和英语–美国手语双通道双语者的证据 总被引:1,自引:0,他引:1
采用同形异义词干扰任务考察第二语言水平对英语–汉语单通道双语者和英语–美国手语双通道双语者语言抑制能力的影响。结果发现:(1)高水平英语–汉语单通道双语者的语言抑制能力较强,但低水平英语–汉语单通道双语者与英语单语者的语言抑制能力没有显著差异,说明少量的双语经验不足以导致双语认知优势;(2)不同水平的英语–美国手语双通道双语者的语言抑制能力差异不显著。所以如此,与英语–美国手语双通道双语者不存在口语和手语的双语表征加工竞争有关。整个研究表明,双语认知优势效应与双语者的二语水平以及通道经验有关。 相似文献
