群体共享情绪的放大效应

相比独自经历情绪事件,在群体中与他人共享情绪事件会放大个体的情绪体验,该效应被称之为群体共享情绪的放大效应。以往研究为群体共享情绪放大效应提供了部分间接的实验证据,但以往的理论,如群体共同关注理论和情绪传染理论,并不能对该效应做出很好的解释。基于社会评估理论和共享现实理论提出的评估–证实–放大模型可较好地解释群体共享情绪的放大效应。未来研究可在真实互动的群体情境中检验群体共享情绪放大效应及评估–证实–放大模型。     

人际感恩:社会交往中重要的积极情绪

人际感恩是指个体由于接受了他人善意提供的具有一定价值的恩惠而诱发的一种愉悦的、心怀感激而意欲报答的认知性情绪。情境评估过程是人际感恩得以产生的关键环节。此外,人际感恩的产生还会受到受惠者自身特点、双方关系特点等因素的影响。情节剧本、真人互动等任务是研究人际感恩的常见范式。另外,人际感恩还具有个体、二元、团体三个层面的功能。加强人际感恩神经生理机制的研究,考察由人际感恩到特质感恩的培养路径,拓展人际感恩的功能研究,探索中国文化背景下的人际感恩是未来人际感恩的研究方向。     

情绪调节中的认知重评创造力

情绪调节能力是维护个体心理健康和生活幸福的基本能力。认知重评创造力是个体面对负性情境时能够自发产生多种认知重评策略的能力,是情绪调节任务中的创造性行为。研究表明,认知重评创造力与发散性思维和开放性正相关,与神经质、特质愤怒无关;创造性的认知重评策略或运用隐喻和类比的高水平认知重构更有利于负性情绪的调节;创造性的认知重评可以通过基于杏仁核的显著情绪唤醒,基于海马的新联想形成和基于纹状体的精神奖赏的中介来调节情绪,从而产生可以保存在长时记忆中的新颖的、积极的情绪体验。上述结果支持认知重评的创造性重构理论。认知重评创造过程需要自上而下的认知控制和情绪表征的特定执行功能。未来研究可以扩大被试群体,完善认知重评创造力的测量方法,探索影响认知重评创造力的情境因素和内在因素,以及进一步揭示认知重评创造力区别于传统创造力的特别加工或反应机制的神经机制。     

Electromyographic Analysis of Responses to Third Person Intergroup Threat

This study attempts to replicate and extend the findings from Davis and Stephan’s (2011) article investigating facial electromyographic (EMG) responses to individually directed or group-directed realistic threat. Using news footage from the Columbine school shootings as a third-person threatening stimulus, participants were instructed to view the clips while considering how they felt during the original events (individually primed) or how students felt during the original events (group-primed). EMG analysis of activity levels of the medial frontalis and the corrugator supercilii indicated differential activation based on the instructions. Individually primed participants experienced more fontalis activity and group-primed participants experienced more corrugator supercilii activity. These findings replicated the Davis and Stephan results and extended it to a third person-based intergroup threat.     

The relationships among gratitude,self‐esteem,depression, and suicidal ideation among undergraduate students

The main purpose of this study was to examine the relationships among gratitude, self‐esteem, depression, and suicidal ideation. In total, 814 undergraduate participants (259 males and 555 females with mean age of 20.13 years) completed four inventories measuring the variables of interest. Analyses of structural equation modeling found that gratitude had direct effects on individuals' self‐esteem, depression, and suicidal ideation. In addition, gratitude had indirect effects on individuals' suicidal ideation via self‐esteem and depression, and self‐esteem had direct effects on individuals' depression. These results support the proposed model of suicidal ideation and contribute to the understanding of how gratitude influences individuals' suicidal ideation via psychological and physical variables.     

Colour fluctuations in grapheme‐colour synaesthesia: The effect of clinical and non‐clinical mood changes

Synaesthesia is a condition that gives rise to unusual secondary sensations (e.g., colours are perceived when listening to music). These unusual sensations tend to be reported as being stable throughout adulthood (e.g., Simner & Logie, 2007, Neurocase, 13, 358) and the consistency of these experiences over time is taken as the behavioural hallmark of genuineness. Our study looked at the influence of mood states on synaesthetic colours. In Experiment 1, we recruited grapheme‐colour synaesthetes (who experience colours from letters/digits) and elicited their synaesthetic colours, as well as their mood and depression states, in two different testing sessions. In each session, participants completed the PANAS‐X (Watson & Clark, 1999) and the BDI‐II (Beck, Steer, & Brown, 1996, Manual for Beck Depression Inventory‐II), and chose their synaesthetic colours for letters A‐Z from an interactive colour palette. We found that negative mood significantly decreased the luminance of synaesthetic colours. In Experiment 2, we showed that synaesthetic colours were also less luminant for synaesthetes with anxiety disorder, versus those without. Additional evidence suggests that colour saturation, too, may inversely correlate with depressive symptoms. These results show that fluctuations in mood within both a normal and clinical range influence synaesthetic colours over time. This has implications for our understanding about the longitudinal stability of synaesthetic experiences, and of how mood may interact with the visual (imagery) systems.     

Illusions of Learning: Irrelevant Emotions Inflate Judgments of Learning

People use assessments of how much they have learned to choose and recommend instructors, seminars, and weekend trips. How do people assess how much they have learned? Recent theorizing has depicted emotion as a cue for learning, and so people may be misled by recent emotional states to infer that they have learned more than they actually have. Four studies showed that people associated emotion with learning and believed, often falsely, that they learned more when in an emotional than unemotional state. Factual lessons were coupled with manipulations of arbitrary, irrelevant emotional states. Participants rated that they learned more after an emotion had been induced than in emotionally neutral control conditions. These differences remained significant after controlling for actual learning as measured by objective tests, which was unaffected by emotion. This illusion of learning caused by emotion was robust with respect to changes of procedure and sample, including whether the emotion came before or after the information to be learned. Alternative explanations were ruled out, including that emotion would intensify ratings generally, that emotion would make incoming information seem particularly personally relevant, that emotion increased engagement in the research, and that illusory learning would depend on retrospective exaggeration of one's prior ignorance. Because irrelevant emotions can increase people's judgments that they have learned something, incidental emotional experiences could increase a person's likelihood of deciding to take another class with a particular instructor, to sign up for another leadership seminar, or to engage in a risky (but emotion‐filled) excursion.

晚期正成分的时间-空间迁移模式在情绪调节发展研究中的应用

近二十年,使用认知神经科学手段探讨情绪调节成为了研究的热点。晚期正成分(Late Positive Potential,LPP)是情绪调节脑电研究中的一个典型成分,在不同的时间窗中分析LPP的波幅的变化及其优势激活脑区的迁移能够反映情绪调节加工过程中个体由对情绪刺激的感知到相应的认知调控过程的转变。LPP的时间-空间迁移模式被应用于情绪调节的发展研究,揭示从童年到青少年再到成年期个体情绪的潜在神经机制。研究者关注幼儿期、童年期、青少期、成人期个体在情绪调节加工过程中LPP波幅的变化及其时间-空间迁移模式特征,把不同年龄段个体情绪调节的发展特点与其大脑关键脑区(主要是前额叶)发育状况进行联系,为儿童身体发育和心理发展的主题提供更多的证据支持。未来的研究应加强对LPP在异常发展研究中应用,关注大脑发育与激素变化对LPP变化的影响,并加强对LPP调节效应的个体差异等问题的探讨。
