认知闭合需要、框架效应与决策偏好

在带有模糊性的决策情境中,决策者个人的认知特征会对其判断决策产生重要影响。通过实验的方法,考察了认知闭合需要和特征框架效应对个体决策偏好的影响。93名工商管理硕士（MBA）参与了实验,研究的结果支持了本研究的3个假设,即认知闭合需要与特征框架效应不仅对被试的决策偏好存在显著的影响,而且二者还存在显著的交互作用。具体来说,研究发现,在模糊情境中：高认知闭合需要的被试偏好于立刻做出决策,而低认知闭合需要的被试偏好于暂缓做出决策;接收到正向框架信息的被试偏好于立刻做出决策,而接收到负向框架信息的被试偏好于暂缓做出决策;认知闭合需要与特征框架对被试的决策偏好还存在显著的交互作用。研究结论为根据个体认知闭合需要的水平来选拔决策者、利用框架效应来影响个体的信息加工方式进而提高决策质量提供了理论依据     

Why Drug Testing in Elite Sport Does Not Work: Perceptual Deterrence Theory and the Role of Personal Moral Beliefs1

Performance‐enhancing drug use by elite athletes is a modern sporting and social concern. We applied a long‐overdue theoretical framework, perceptual deterrence, to predicting the banned drug‐use decisions of 116 elite Australian footballers and soccer players. The strongest influence on athletes' hypothetical decisions to use drugs was their personal moral beliefs and health concerns, each of which also mediated the relationship between drug testing and athletes' decisions to use banned substances. Drug testing had little influence on athletes' imagined drug use decisions, although there are athletes for whom legal sanctions are necessary. The results have important implications for the way in which authorities fund and frame future anti‐drug initiatives; particularly the relationship between drug testing and athletes' personal moral beliefs.     

Differences in Mathematical Performance,Creativity Potential,and Need for Cognitive Closure between Chinese and Australian Students

Research has shown that Chinese students outperform students from several Western countries on mathematics performance while some evidence has suggested that Western students perform more strongly on tests of creativity. One potential mechanism for these differences may be a higher need for cognitive closure among Chinese students. The current research compared performance on tests of mathematics and creativity among 50 students of Chinese background and 49 Australian students of Anglo‐Saxon background. As predicted, Chinese students performed better on mathematics while Australian students performed better on the measure of creativity. Australian students also had a lower score on one subscale of the need for cognitive closure, preference for predictability. Across the sample, preference for predictability showed small but significant negative correlations with several measures of creativity and positive correlations with several measures of mathematics. These findings were interpreted with respect to characteristic educational practices in both nations.     

Everyday Cognitive Functioning in Cardiac Patients: Relationships Between Self-report,Report of a Significant Other and Cognitive Test Performance

ABSTRACT

Candidates for cardiac bypass surgery often experience cognitive decline. Such decline is likely to affect their everyday cognitive functioning. The aim of the present study was to compare cardiac patients' ratings of their everyday cognitive functioning against significant others' ratings and selected neuropsychological tests. Sixty-nine patients completed a battery of standardised cognitive tests. Patients and significant others also completed the Everyday Function Questionnaire independently of each other. Patient and significant other ratings of patients' everyday cognitive difficulties were found to be similar. Despite the similarities in ratings of difficulties, some everyday cognitive tasks were attributed to different processes. Patients' and significant others' ratings were most closely associated with the neuropsychological test of visual memory. Tests of the patients' verbal memory and fluency were only related to significant others' ratings. Test scores of attention and planning were largely unrelated to ratings by either patients or their significant others.     

A Place for Individual Differences in What Everyone Knows About What Everyone Does: Positive Affect,Cognitive Processes,and Cognitive Experiential Self Theory

Individual differences are often incorporated into experimental research to elucidate inconsistent effects. We argue that the inclusion of such differences into established and seemingly straightforward findings is imperative to the goal of reaching a more complete understanding about the processes of interest. Drawing on research on the cognitive effects of positive affect, we illustrate how integrating individual differences in cognitive processing styles to this literature might lead to a more nuanced understanding of the impact of affect on cognitive processes. The addition of individual differences to psychological research should be seen as a means to a thorough scientific comprehension of a topic rather than as burdensome caveats to otherwise straightforward findings.     

The Relationship of Promotion Focus,Need for Cognitive Closure,and Categorical Accessibility in American and Hong Kong Chinese University Students

Categorical accessibility is a cognitive factor that limits the extent of creative conceptual expansion. In the present study, we sought to establish the categorical accessibility norms in five conceptual domains among American and Hong Kong Chinese university students. In addition, we predicted that the tendency to access normatively inaccessible exemplars in a conceptual domain is positively related to the motivation to maximize the likelihood of attaining positive outcomes (promotion focus) and negatively related to the need for cognitive closure. We obtained the predicted relationships among both American and Hong Kong Chinese university students. These findings were discussed in terms of their implications for promoting creativity across cultures.     

Portable Myoelectric Brace Use Increases Upper Extremity Recovery and Participation But Does Not Impact Kinematics in Chronic,Poststroke Hemiparesis

The authors examined the efficacy of an 8-week regimen combining repetitive task-specific practice (RTP) with a myoelectric brace (RTP+Myomo) on paretic upper extremity (UE; use in valued activities, perceived recovery, and reaching kinematics) in 12 subjects (4 men; M age = 53.5 years; mean time poststroke = 61.7 months). Seven subjects were administered RTP+Myomo therapy, and 5 were administered RTP only. Both groups participated in individualized, 45-min therapy sessions occurring 3 days/week over an 8-week period. The arm, hand ability, activities of daily living, and perceptions of recovery subscales of the Stroke Impact Scale (SIS), as well as UE reaching kinematics, assessed before and after the intervention. Subjects in the RTP+Myomo group showed greater improvements on all SIS subscales, with the recovery scale reaching statistical significance (p = .03). Subjects in the RTP-only group showed a greater increase in hand velocity in the reach up task (p = .02), but no changes were observed in the range of shoulder flexion or elbow extension during reaching. None of the changes in kinematic outcome measures significantly correlated with any of the changes in SIS subscales. RTP integrating myoelectric bracing may be more beneficial than RTP only in improving self-reported function and perceptions of overall recovery. The authors observed no changes in the range of elbow extension, and no relationship between self-reported improvements and changes in reaching kinematics.
