情绪效价的记忆增强效应:存储或提取优势?

情绪效价和情绪唤醒是描述情绪的两个维度。情绪增强记忆效应表明情绪唤醒事件的记忆往往优于非情绪唤醒事件的记忆,但关于积极情绪记忆和消极情绪记忆哪个在记忆中处于优势仍存在争论。实验以情绪词对和中性词对为实验材料。实验一探讨积极情绪词语或消极情绪词语的记忆优势; 实验二探讨积极情绪环境或消极情绪环境中中性词语的记忆优势。在两种实验条件下,积极情绪下的自由回忆都优于消极情绪下的自由回忆; 多项加工树的存储—提取模型使用实验自由回忆和线索回忆的结果将记忆的存储和提取优势分离开来,结果表明:积极情绪事件记忆优势发生在存储阶段,而积极情绪环境记忆优势发生在存储和提取阶段; 积极情绪事件记忆偏向支持“刺激后编码增强假设”,积极情绪环境记忆偏向支持“唤醒—偏向竞争假设”。     

不同回避动机强度的消极情绪对类比推理的影响:来自ERP的证据

研究采用类比推理的四项比例式任务和事件相关电位技术,探究不同回避动机强度的消极情绪(恐惧—高动机强度、悲伤—低动机强度、中性情绪)对类比推理的影响及脑机制。结果发现:(1)行为:不同回避动机强度的消极情绪均会延长类比推理的反应时; 与中性情绪相比,悲伤会提高推理的正确率,而恐惧会降低推理的正确率。(2)脑电:图式提取阶段,N400、P300、LNC被诱发; 类比映射阶段,N400和LNC被诱发,情绪在N400和LNC上的主效应均显著,恐惧情绪下的N400和LNC幅值比悲伤情绪和中性情绪下的更大。研究表明,情绪对类比推理的作用发生在类比映射阶段。恐惧情绪窄化认知,悲伤情绪扩展认知,支持情绪动机维度模型。     

中等强度情绪性图片的神经机制——一项fMRI研究

采用修订后的中等唤起度的国际情绪图片为刺激材料,以12名女性大学生为被试,考察情绪性图片引起的脑激活模式。结果发现,与中性条件相比,消极情绪图片激活了枕叶、杏仁核、海马旁回和壳核。积极情绪图片引起枕叶、内侧眶额、额中回等脑区的激活,研究结果再次验证了杏仁核与消极情绪的密切关系,同时推测,内侧眶额可能是中等唤起度的趋近性积极情绪的一个脑功能区。     

FilmStim情绪影片数据库在中国大学生中的初步评定

本研究利用主观情绪唤醒度、正负性和分化情绪量表对FilmStim大型情绪影片数据库进行本土化评定。研究发现,所有情绪影片唤醒水平均显著高于中性影片;正、负性情绪影片诱发相应效价的情绪;悲伤、恐惧、厌恶和中性影片成功诱发目标情绪,愤怒、温和和愉快影片同时诱发同效价的其他情绪。结果表明:FilmStim中的中性影片可作为其他情绪的控制条件;除愤怒外的负性影片可有效诱发目标情绪;正性情绪影片没有有效诱发目标情绪,存在较大文化差异。     

身体攻击行为学生自主神经活动的情绪唤醒特点

运用情绪生理学的方法,以31名具有身体攻击行为的初中工读学生和30名普通初中生为研究对象,研究了身体攻击行为学生与普通学生在基线生理唤醒和情绪生理唤醒的方面不同特点。结果发现,在生理唤醒的基线水平上,身体攻击行为学生与普通学生在指温、R-R间期、心率、指脉率方面差异显著,身体攻击行为学生的指温、心率、指脉率比普通学生低,身体攻击行为学生的R-R间期比普通学生R-R间期长。在愤怒刺激条件下,身体攻击行为学生报告的愤怒体验水平比普通学生高;愤怒诱发刺激引起身体攻击行为学生R-R间期、心率变化显著,而普通学生R-R间期、心率变化不显著。厌恶与恐惧、悲伤、愉快诱发刺激引起普通学生皮肤电变化显著,而身体攻击行为学生皮肤电变化不显著     

词语后情绪环境对语义和感知加工的影响

词语后情绪环境对其中的事件记忆产生影响,但是事件后情绪环境如何影响记忆加工仍不清楚。不同的情绪环境理论—“唤醒偏向竞争理论”,“拓宽-建构理论”,“记忆中心的积极情绪促进理论”支持情绪促进的不同本质。已有的研究表明,注意在情绪记忆中有重要作用。实验一、实验二分别探讨词语后情绪环境对其语义加工与内源源加工和外源源加工的影响。与中性环境相比,积极与消极情绪环境阻碍了外源源特征的加工; 与中性环境和积极情绪环境相比,消极情绪环境阻碍了内源源特征的加工。实验结果支持“唤醒偏向竞争理论”,同时表明“评估”和“注意放置”在情绪环境影响中的重要作用。     

不同心理弹性大学新生的积极消极情绪特征

该研究采用颜色词的stroop研究范式,探讨了积极、消极情绪诱导下,大一新生对积极、消极、中性三类颜色词的反应时辨别差异与错误率。实验结果表明,在消极情绪诱导下,高心理弹性个体在消极词汇上表现出较快的反应时;在积极情绪诱导下,高心理弹性个体在积极词汇上表现出较快的反应时;内隐实验获得的情绪反应倾向与心理弹性量表所测的外显情绪反应倾向趋于一致。结论:高心理弹性大学新生具有较多的积极情绪。     

积极情绪对注意范围和思维活动序列的影响

为了探究积极情绪对注意范围和思维活动序列的影响,125个大学生参与两项实验,在每个实验中,随机安排不同性别的被试观看使人产生高兴、安宁、中性、悲伤、愤怒情绪的视频片段。实验1用整体-局部视觉加工任务测量被试的注意范围,实验2用一个含有20个句子的开放式问卷测量被试的思维活动序列。结果发现:积极情绪对注意范围的影响受到性别因素的影响,积极情绪拓宽女生的注意范围,缩小男生的注意范围;积极情绪拓宽思维活动序列,不存在性别差异。     

职前教师情绪觉察能力对情绪信息注意偏向的影响

采用修订的情绪觉察水平量表（LEAS）对315名职前教师进行调查,并从中筛选出高、低情绪觉察能力组被试各60人,分别完成情绪面孔Stroop任务（研究1）和情绪词Stroop任务（研究2）。（1）研究1的正确率上,中性面孔最高,愉快面孔次之,悲伤面孔最差;反应时上,悲伤面孔最长,愉快面孔次之,中性面孔最短;高分组仅在愉快和中性面孔上的反应时长于低分组;消极面孔的干扰效应高于积极面孔的干扰效应。（2）研究2的反应时上,消极词的反应时最长,显著长于中性和积极词;高分组仅在积极词和中性词上的反应时长于低分组,且高分组在积极词上的干扰效应高于低分组。研究结果表明与中性刺激相比,高低情绪觉察能力组均对情绪刺激产生了注意偏向,尤其是负性情绪刺激;与低情绪觉察能力组相比,高情绪觉察能力职前教师不仅对消极情绪信息产生注意偏向,还对积极情绪信息产生注意偏向。     

Feeling good: autonomic nervous system responding in five positive emotions

Although dozens of studies have examined the autonomic nervous system (ANS) aspects of negative emotions, less is known about ANS responding in positive emotion. An evolutionary framework was used to define five positive emotions in terms of fitness-enhancing function, and to guide hypotheses regarding autonomic responding. In a repeated measures design, participants viewed sets of visual images eliciting these positive emotions (anticipatory enthusiasm, attachment love, nurturant love, amusement, and awe) plus an emotionally neutral state. Peripheral measures of sympathetic and vagal parasympathetic activation were assessed. Results indicated that the emotion conditions were characterized by qualitatively distinct profiles of autonomic activation, suggesting the existence of multiple, physiologically distinct positive emotions.     

Positive Emotions Speed Recovery from the Cardiovascular Sequelae of Negative Emotions

Two studies tested the hypothesis that certain positive emotions speed recovery from the cardiovascular sequelae of negative emotions. In Study 1, 60 subjects (Ss) viewed an initial fear-eliciting film, and were randomly assigned to view a secondary film that elicited: (a) contentment; (b) amusement; (c) neutrality; or (d) sadness. Compared to Ss who viewed the neutral and sad secondary films, those who viewed the positive films exhibited more rapid returns to pre-film levels of cardiovascular activation. In Study 2, 72 Ss viewed a film known to elicit sadness. Fifty Ss spontaneously smiled at least once while viewing this film. Compared to Ss who did not smile, those who smiled exhibited more rapid returns to pre-film levels of cardiovascular activation. We discuss these findings in terms of emotion theory and possible health-promoting functions of positive emotions.

Sadness and amusement reactivity differentially predict concurrent and prospective functioning in major depressive disorder

Depressed individuals often fail to react to emotionally significant stimuli. The significance of this pattern of emotional dysregulation in depression is poorly understood. In the present study, depressed and nondepressed participants viewed standardized neutral, sad, fear, and amusing films; and experiential, behavioral, and physiological responses to each film were assessed. Compared with nondepressed controls, depressed participants reported sadness and amusement in a flattened, context-insensitive manner. Those depressed participants who reported the least reactivity to the sad film exhibited the greatest concurrent impairment. Prospectively, the depressed participant who exhibited the least behavioral and heart rate reactivity to the amusing film were the least likely to recover from depression. Loss of the context-appropriate modulation of emotion in depression may reflect a core feature of emotion dysregulation in this disorder.     

Emotions induced by operatic music: psychophysiological effects of music, plot, and acting: a scientist's tribute to Maria Callas

Operatic music involves both singing and acting (as well as rich audiovisual background arising from the orchestra and elaborate scenery and costumes) that multiply the mechanisms by which emotions are induced in listeners. The present study investigated the effects of music, plot, and acting performance on emotions induced by opera. There were three experimental conditions: (1) participants listened to a musically complex and dramatically coherent excerpt from Tosca; (2) they read a summary of the plot and listened to the same musical excerpt again; and (3) they re-listened to music while they watched the subtitled film of this acting performance. In addition, a control condition was included, in which an independent sample of participants succesively listened three times to the same musical excerpt. We measured subjective changes using both dimensional, and specific music-induced emotion questionnaires. Cardiovascular, electrodermal, and respiratory responses were also recorded, and the participants kept track of their musical chills. Music listening alone elicited positive emotion and autonomic arousal, seen in faster heart rate, but slower respiration rate and reduced skin conductance. Knowing the (sad) plot while listening to the music a second time reduced positive emotions (peacefulness, joyful activation), and increased negative ones (sadness), while high autonomic arousal was maintained. Watching the acting performance increased emotional arousal and changed its valence again (from less positive/sad to transcendent), in the context of continued high autonomic arousal. The repeated exposure to music did not by itself induce this pattern of modifications. These results indicate that the multiple musical and dramatic means involved in operatic performance specifically contribute to the genesis of music-induced emotions and their physiological correlates.     

Effects of worry on physiological and subjective reactivity to emotional stimuli in generalized anxiety disorder and nonanxious control participants

The present study examined the effect of worry versus relaxation and neutral thought activity on both physiological and subjective responding to positive and negative emotional stimuli. Thirty-eight participants with generalized anxiety disorder (GAD) and 35 nonanxious control participants were randomly assigned to engage in worry, relaxation, or neutral inductions prior to sequential exposure to each of four emotion-inducing film clips. The clips were designed to elicit fear, sadness, happiness, and calm emotions. Self reported negative and positive affect was assessed following each induction and exposure, and vagal activity was measured throughout. Results indicate that worry (vs. relaxation) led to reduced vagal tone for the GAD group, as well as higher negative affect levels for both groups. Additionally, prior worry resulted in less physiological and subjective responding to the fearful film clip, and reduced negative affect in response to the sad clip. This suggests that worry may facilitate avoidance of processing negative emotions by way of preventing a negative emotional contrast. Implications for the role of worry in emotion avoidance are discussed.     

The up- and down-regulation of amusement: experiential, behavioral, and autonomic consequences

A growing body of research has examined the regulation of negative emotions. However, little is known about the physiological processes underlying the regulation of positive emotions, such as when amusement is enhanced during periods of stress or attenuated in the pursuit of social goals. The aim of this study was to examine the psychophysiological consequences of the cognitive up- and down-regulation of amusement. To address this goal, participants viewed brief, amusing film clips while measurements of experience, behavior, and peripheral physiology were collected. Using an event-related design, participants viewed each film under the instructions either to (a) watch, (b) use cognitive reappraisal to increase amusement, or (c) use cognitive reappraisal to decrease amusement. Findings indicated that emotion experience, emotion-expressive behavior, and autonomic physiology (including heart rate, respiration, and sympathetic nervous system activation) were enhanced and diminished in accordance with regulation instructions. This finding is a critical extension of the growing literature on the voluntary regulation of emotion, and has the potential to help us better understand how people use humor in the service of coping and social goals.     

Love alters autonomic reactivity to emotions

Periods of bond formation are accompanied by physiological and emotional changes, yet, little is known about the effects of falling in love on the individual's physiological response to emotions. We examined autonomic reactivity to the presentation of negative and positive films in 112 young adults, including 57 singles and 55 new lovers who began a romantic relationship 2.5 months prior to the experiment Autonomic reactivity was measured by Respiratory Sinus Arrhythmia (RSA) to two baseline emotionally neutral films, two negative films, and two positive films. Results demonstrated that RSA in singles decreased during the presentation of negative emotions, indicating physiological stress response. However, no such decrease was found among new lovers, pointing to more optimal vagal regulation during the period of falling in love. Autonomic reactivity, indexed by RSA decrease from the positive to the negative films, was greater among singles as compared to lovers, suggesting that love buffers against autonomic stress and facilitates emotion regulation. Findings suggest that vagal regulation may be one mechanism through which love and attachment reduce stress and promote well-being and health.     

A standardised database of Chinese emotional film clips

Film clips are widely used in emotion research due to their relatively high ecological validity. Although researchers have established various film clip sets for different cultures, the few that exist related to Chinese culture do not adequately address positive emotions. The main purposes of the present study were to establish a standardised database of Chinese emotional film clips that could elicit more categories of reported positive emotions compared to the existing databases and to expand the available film clips that can be used as neutral materials. Two experiments were conducted to construct the database. In experiment 1, 111 film clips were selected from more than one thousand Chinese movies for preliminary screening. After 315 participants viewed and evaluated these film clips, 39 excerpts were selected for further validation. In experiment 2, 147 participants watched and rated these 39 film clips, as well as another 8 excerpts chosen from the existing databases, to compare their validity. Eventually, 22 film excerpts that successfully evoked three positive emotions (joy, amusement, and tenderness), four negative emotions (moral disgust, anger, fear, and sadness), and neutrality formed the standardised database of Chinese emotional film clips.     

"Just stop thinking about it": effects of emotional disengagement on children's memory for educational material

Children regulate negative emotions in a variety of ways. Emotion education programs typically discourage emotional disengagement and encourage emotional engagement or "working through" negative emotions. The authors examined the effects of emotional disengagement and engagement on children's memory for educational material. Children averaging 7 or 10 years of age (N=200) watched either a sad or an emotionally neutral film and were then instructed to emotionally disengage, instructed to engage in problem solving concerning their emotion, or received no emotion regulation instructions. All children then watched and were asked to recall the details of an emotionally neutral educational film. Children instructed to disengage remembered the educational film better than children instructed to work through their feelings or children who received no emotion regulation instructions. Although past research has indicated that specific forms of emotional disengagement can impair memory for emotionally relevant events, the current findings suggest that disengagement is a useful short-term strategy for regulating mild negative emotion in educational settings.
