对恐怖情绪的调节:认知重评和表达抑制的差异——一项ERP研究

本研究采用事件相关电位(ERP)技术,通过测量由视觉诱发的脑电成分晚正波(LPP)来比较情绪调节策略在生理电特征上的差异,探讨认知重评和表达抑制的优劣。实验结果表明:(1)从波幅的角度来比较:在400—600ms时间窗口内,认知重评条件下恐怖图片诱发的LPP波幅显著小于在自由观看条件下的波幅,而表达抑制和自由观看组所诱发的LPP波幅差异较小。(2)从时间进程的角度来比较:认知重评与自由观看组的差异发生在400ms并持续到600ms;而表达抑制和自由观看之间的差异发生在450ms但是只持续到550ms。这表明认知重评相较于表达抑制,对负性情绪起调节作用开始较早,并且持续时间较长。这为认知重评优于表达抑制策略提供了神经生理学上的证据。

Is synaesthesia one condition or many? A large-scale analysis reveals subgroups

Synaesthesia is a broadly defined neural phenomenon in which stimulation of a sense or concept triggers a second perception not normally associated with the stimulus. For example, letters or numbers may trigger a colour experience, sounds may trigger a taste sensation, or tastes may trigger a feeling of touch. Dozens of forms of synaesthesia have been reported, but the relationship between the different forms has not been studied: is someone with a particular form of synaesthesia likely to possess other types? If so, which ones? As an inroad to illuminating underlying mechanisms, we here examine which different synaesthesia types tend to co-occur. We analyzed reports of the forms of synaesthesia experienced by 19,133 participants who completed the Synaesthesia Battery (Eagleman, Kagan, Nelson, Sagaram, & Sarma, 2007), using correlation analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and multidimensional scaling (MDS). Our analyses converged on the finding of five distinct groupings of synaesthesia forms. We label these coloured sequence synaesthesias (CSSs), coloured music synaesthesias, non-visual sequela synaesthesias, spatial sequence synaesthesia (SSS), and coloured sensation synaesthesias. Collectively, our findings reveal that synaesthesia is an umbrella term that encompasses several distinct groups with independent probabilities of expression, and this may in turn suggest distinct underlying mechanisms and the possibility of different genetic bases.     

成就目标、学业情绪及学业成绩的关系研究述评

成就目标(Achievement Goal)是个体对从事成就活动的目的或意义的知觉,学业情绪(Academic Emotion)是指与学业学习、班级指导和学业成就直接相关的各种情绪。成就目标与学业情绪相互作用,即成就目标会影响学生的学业情绪,学业情绪反过来也会影响成就目标。同时,成就目标和学业情绪对学生的学业成绩具有综合预测作用,学业情绪在成就目标和学业成绩间起中介作用。未来研究的方向主要在于深入探讨成就目标与更细分的学业情绪的关系,以及成就目标、学业情绪和成绩之间的相互作用。     

the transition experiences of successful chinese immigrants

This article focused on the transition experiences of 20 successful Chinese immigrants, in particular their transition stories and how they accounted for their success (what facilitated and hindered their transition). An enhanced critical incident method was used for data analysis. Four major success categories emerged: having a positive attitude and personality, skills and resource development, education and work experience, and community and family support. There was less emphasis on hindering categories, but some problems were identified. There was specific information on the effectiveness of the employment counseling process from those who had participated in an employment counseling program.     

Social status,cognitive ability,and educational attainment as predictors of liberal social attitudes and political trust

We examined the prospective associations between family socio-economic background, childhood intelligence (g) at age 11, educational and occupational attainment, and social attitudes at age 33 in a large (N = 8804), representative sample of the British population born in 1958. Structural equation Modeling identified a latent trait of ‘liberal social attitudes’ underlying attitude factors that are antiracist, socially liberal, and in support of gender equality. Another attitude factor—‘political trust’—was relatively independent from the latent attitude trait and has somewhat different pathways in relation to the other variables included in the analysis. There was a direct association between higher g at age 11 and more liberal social attitudes and political trust at age 33. For both men and women the association between g and liberal social attitudes was partly mediated via educational qualifications, and to a much lesser extent via adult occupational attainment. For women the association between g and political trust was partly mediated through both educational qualification and occupational attainment, and for men it was mediated mainly via occupational attainment. Men and women who had higher educational qualifications and higher occupational status tend to be more socially liberal and more trusting of the democratic political system. In terms of socio-economic background, people from less privileged families showed less political trust, but did not differ much in liberal social attitudes from those born into relatively more privileged circumstances. This study shows that social background, cognitive ability, education, and own social status influence perceptions of society.     

The perseverance of numerical distance effect in attentional blink

In a number comparison task, it is easier to respond faster when the two numbers are further apart than when they are close. This inverse relationship between the size difference and the time to judge such difference is called the numerical distance effect (NDE). In this study we investigated whether attention plays a critical role in the surfacing of NDE and the way we process Arabic numbers. In experiments 1 and 2, with an attentional blink paradigm that was designed to modulate attention, we tested whether a limited or unlimited pool of attentional resources would have an impact on the performance and trend of NDE. The results showed a dissociable effect of attention that changed the overall accuracy but not the trend of NDE. In experiment 3 we examined whether the number priming effect, another phenomenon associated with the distance-related effect, would be affected during the attentional blink period. We found the pattern of number priming effect was not affected by attentional blink. An explanation of the role of attention in number distance processing, as well as how it interacts with Arabic number representation, is discussed.     

对骨折治疗"优化选择"与"合理选择"的理解和思考

从合理化角度回顾了当前几种重要的骨折治疗理论体系的发展与演变,认为骨折治疗的最优原则是一种理想状态,现实中没有绝对最优只有相对合理.只有建立以患者为中心的思维体系,加强医疗逻辑思维能力,用多维思考的方式寻找矛盾的合理平衡点,始终坚守医学伦理道德底线,才能真正做到为每一位骨折患者进行最合理的治疗.
