脆弱高自尊在自我威胁后的归因与情绪转换

对89名大学生被试在自我威胁条件下的归因与情绪模式进行了实验室研究。结果发现:(1)自我威胁条件下,脆弱高自尊个体会产生即刻的强烈羞愧情绪,之后通过外归因将这种向内的羞愧转换为向外的高敌意;(2)低自尊个体在自我威胁条件下,也会产生即刻的强烈羞愧感,但其外归因和敌意情绪均保持在较低水平,未出现归因与情绪转换。研究结果支持自我威胁后的归因与情绪转换假设。     

Do working memory-driven attention shifts speed up visual awareness?

Previous research has shown that content representations in working memory (WM) can bias attention in favor of matching stimuli in the scene. Using a visual prior-entry procedure, we here investigate whether such WM-driven attention shifts can speed up the conscious awareness of memory-matching relative to memory-mismatching stimuli. Participants were asked to hold a color cue in WM and to subsequently perform a temporal order judgment (TOJ) task by reporting either of two different-colored circles (presented to the left and right of fixation with a variable temporal interval) as having the first onset. One of the two TOJ circles could match the memory cue in color. We found that awareness of the temporal order of the circle onsets was not affected by the contents of WM, even when participants were explicitly informed that one of the TOJ circles would always match the WM contents. The null effect of WM on TOJs was not due to an inability of the memory-matching item to capture attention, since response times to the target in a follow-up experiment were improved when it appeared at the location of the memory-matching item. The present findings suggest that WM-driven attention shifts cannot accelerate phenomenal awareness of matching stimuli in the visual field.     

A Multilevel Investigation of Missing Links Between Transformational Leadership and Task Performance: The Mediating Roles of Perceived Person-Job fit and Person-Organization Fit

Purpose  

This study explores whether follower perceived need-supply (N-S) job fit, demand-ability (D-A) job fit, and person-organization (P-O) fit mediate the relationships between individual-level, unit-level transformational leadership (TFL), and follower task performance.     

Langzeitergebnisse einer Funktionellen-Magnetresonanztomographie-Studie

In a controlled functional magnetic resonance imaging (fMRI) study the effect of psychodynamic short-term psychotherapy on cerebral activation of panic disorder patients was determined. In a linguistic go-no go paradigm behavioral measures and cerebral activation to affective word stimuli with threatening, neutral and positive content were assessed pretreatment and post-treatment in 9 patients with panic disorder. 18 healthy controls were scanned twice at the same intervals. In an additional long-term follow-up after approximately 3 years post-treatment the effect of brain activation changes during treatment on the long-term outcome of core symptoms (panic-related cognition and fear of body sensations) were determined. In accordance with the hypotheses increased limbic (hippocampus and amygdala) activation accompanied by low prefrontal activation to negative words were found. At treatment termination, panic-related symptoms had improved significantly and fronto-limbic activation patterns were normalized. Reduction of activation of the limbic system during treatment was predictive of a favorable long-term outcome. The results indicate that short-term psychodynamic treatment leads to changes in fronto-limbic networks, similar to previous findings on cognitive-behavioural treatment.

Working memory modulates the perception of time

Recent research has indicated that reentrant feedback from the contents of working memory can enhance neural representations and the perceptual strengths of matching stimuli in the visual field. However, whether the contents of working memory can also distort conscious experiences of perception remains unclear. Our present results show that the durations of perceptual stimuli matching the nontemporal representations in working memory tend to be perceived as longer than those of mismatching stimuli. This is the first demonstration that working memory can lead to distortions of time perception. Our findings are consistent with the ideas that the perceived duration of a stimulus depends on the magnitude of the neural responses to that stimulus in visual cortex and that there is a common system for representing both temporal and nontemporal magnitudes. We conclude that top-down modulation from the nontemporal contents of working memory distorts the perceptual experience of temporal duration.     

Recognizing vocal emotions in Mandarin Chinese: A validated database of Chinese vocal emotional stimuli

To establish a valid database of vocal emotional stimuli in Mandarin Chinese, a set of Chinese pseudosentences (i.e., semantically meaningless sentences that resembled real Chinese) were produced by four native Mandarin speakers to express seven emotional meanings: anger, disgust, fear, sadness, happiness, pleasant surprise, and neutrality. These expressions were identified by a group of native Mandarin listeners in a seven-alternative forced choice task, and items reaching a recognition rate of at least three times chance performance in the seven-choice task were selected as a valid database and then subjected to acoustic analysis. The results demonstrated expected variations in both perceptual and acoustic patterns of the seven vocal emotions in Mandarin. For instance, fear, anger, sadness, and neutrality were associated with relatively high recognition, whereas happiness, disgust, and pleasant surprise were recognized less accurately. Acoustically, anger and pleasant surprise exhibited relatively high mean f0 values and large variation in f0 and amplitude; in contrast, sadness, disgust, fear, and neutrality exhibited relatively low mean f0 values and small amplitude variations, and happiness exhibited a moderate mean f0 value and f0 variation. Emotional expressions varied systematically in speech rate and harmonics-to-noise ratio values as well. This validated database is available to the research community and will contribute to future studies of emotional prosody for a number of purposes.

明清闽台地区雷海青信仰兴盛探微

雷海青,俗称田都元帅、田公元帅、相公爷等,天宝年间,唐明皇“命天下梨园祀之”①,其信仰现象出现较早。但是从目前调查情况看,明清时期雷海青成为闽台等地信仰广泛的特殊神灵,其信仰状况相当兴盛:一方面被闽台戏业艺人奉为祖师爷和保护神;另一方面随着闽戏的传播和闽人的外移,     

选择性注意与视觉空间工作记忆的交互作用

传统上只是从单方面讨论了选择性注意与视觉空间工作记忆之间的关系,即认为注意选择有限信息以进入工作记忆。近期的一些研究发现,视觉空间工作记忆的内容影响选择性注意的分配,注意选择工作记忆中保持的空间或物体表征,选择性注意对于正确保持空间或物体信息是必需的认知调节。文章最后指出,关于选择性注意与视觉空间工作记忆交互作用的研究为将来进一步揭示基于空间与基于物体的注意选择之间的交互作用关系提供了一个很好的途径。     

基于空间与基于物体的视觉选择的交互作用

已有的大量实验证据表明,基于空间和基于物体的注意成分都存在于视觉系统中,两者并不是相互排斥的。然而,过去对基于空间和基于物体的视觉选择的研究是分别在非常不同的实验范式下进行的,从而导致对两种注意成分之间的内在关系的理论争论。本文介绍近十年来在单任务范式下对基于空间和基于物体的注意的内在关系的研究,并指出未来的研究应该重点从神经生理水平上揭示两种注意成分之间的交互作用关系。
