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。 相似文献

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. 相似文献

Following a landmark component analysis of cognitive therapy by Jacobson and colleagues (1996), there has been renewed interest in behavioral activation (BA) treatments for depression. The Behavioral Activation for Depression Scale (BADS) was developed to measure when and how clients become activated over the course of BA treatment. Multiple studies have provided initial support for the BADS but have also identified several potential problems. Four studies were conducted in order to develop and provide initial evaluation of a short form of the BADS that addresses these concerns. In Study 1, an exploratory factor analysis was conducted on existing data using the original BADS in order to identify items to retain for the short form. In Study 2, these items were administered to a new sample of college students with elevated depressive symptoms and were analyzed with exploratory and confirmatory factor analyses. Study 3 examined the predictive validity of the BADS-SF by examining the BADS-SF and depression scores in relation to activity tracking and reward-value ratings over the course of 1 week. Study 4 examined BADS-SF data over the course of BA treatment for two clients using cross-lagged panel correlations. With one client, changes in BADS-SF scores led changes in depression scores by 1 week, whereas with the other client changes in BADS-SF and depression scores occurred concurrently. These studies resulted in a nine-item scale that demonstrated good item characteristics as well as acceptable internal consistency reliability, construct validity, and predictive validity. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

The present study investigated whether offset cues have the same attentional consequences in the spatial Stroop effect as
onset cues. Experiments 1 and 2 compared the attentional effects of onset–offset cues versus offset cues on the spatial Stroop
effect, whereas Experiment 3 compared the attentional effects of onset versus offset cues. Across these experiments, independent
of cue type (onset–offset or onset vs. offset) and even at long stimulus-onset asynchrony, attentional cueing did not revert
into inhibition of return and was modulated by spatial Stroop with greater cueing effects for incongruent arrow’s direction
and position. In addition, onset–offset or onset and offset cues produced comparable cueing effects in the location-direction
congruent condition, and onset–offset or onset cues produced greater facilitation than offset cues in the incongruent condition.
From a different perspective, peripheral cueing modulated the spatial Stroop effect in the same direction for onset–offset
or onset and offset cues, although the reduction in spatial Stroop at cued locations was smaller with offset than with onset–offset
or onset cues. 相似文献
