情绪对延迟折扣的影响：现状、机制与展望

延迟折扣研究领域日益重视情绪的影响作用。本文基于三类研究取向对情绪与延迟折扣关系研究进行了回顾。情绪效价和唤醒度均影响延迟折扣,但是研究结果并不一致;具体情绪类型不同,其对延迟折扣影响也存在差异。除此之外,本文就情绪信息理论、情绪动机维度理论和评估倾向理论如何解释延迟折扣进行了详细阐述。未来的研究需要进一步深入考察情绪影响延迟折扣的认知神经机制,从而为延迟折扣的负性情绪效应的干预提供可靠的科学依据。     

情绪设计对多媒体学习的影响

通过两个实验探讨多媒体学习中情绪设计对学习者情绪、认知过程和学习结果的影响。实验1将内部情绪设计与外部情绪诱发两种方式结合起来,探讨多媒体学习环境中不同方式诱发的积极情绪对学习的影响。实验2进一步聚焦于内部情绪设计,考察颜色和拟人化这两个特定的情绪设计元素对学习者情绪和学习的影响。结果发现:(1)积极的外部情绪诱发和内部情绪设计可以诱发积极情绪,并促进学习迁移。(2)对学习材料进行内部积极情绪设计可以诱发学习者积极情绪,增强学习者的学习动机,降低学习者感知到的学习材料的难度,并促进学习迁移。其中,彩色设计可以诱发学习者积极情绪,但拟人化只有与彩色结合才能诱发学习者积极情绪;在拟人化条件下,彩色设计可以增强学习者学习动机;彩色设计可降低学习者对学习材料感知到的难度;彩色和拟人化都可以促进学习迁移。     

Delay discounting as emotional processing: An electrophysiological study

Both theoretical models and functional imaging studies implicate the involvement of emotions within the delay discounting process. However, defining this role has been difficult to establish with neuroimaging techniques given the automaticity of emotional responses. To address this, the current study examined electrophysiological correlates involved in the detection and evaluation of immediate and delayed monetary outcomes. Our results showed that modulation of both early and later ERP components previously associated with affective stimuli processing are sensitive to the signalling of delayed rewards. Together with behavioural reaction times that favoured immediacy, we demonstrated, for the first time, that time delays modify the incentive value of monetary rewards via mechanisms of emotional bias and selective visual attention. Furthermore, our data are consistent with the hypothesis that delayed and thus intangible rewards are perceived less saliently, and rely on emotion as a common currency within decision making. This study provides a new approach to delay discounting and highlights a potential novel route through which delay discounting may be investigated.     

情景预见对跨期决策的影响机制

为了探究情景预见对跨期决策的影响机制, 研究采用延迟折扣任务范式, 检验了在情景预见对跨期决策的影响中延迟时间知觉起到的中介作用。两个实验分别操纵了情景预见中未来事件与自我有关的信息和未来事件的情绪特征, 结果均发现情景预见通过改变个体对延迟等待时间的时距知觉影响了跨期决策。想象与自己、与母亲有关的未来事件, 想象积极、中性情绪效价的未来事件都使得被试将延迟等待时间知觉为较短的时间段, 更倾向于选择延迟奖励。想象消极情绪效价的未来事件使得被试将延迟等待时间知觉为较长的时间段, 更加偏好即时奖励。本研究有助于增进人们对情景预见影响跨期决策现象的理解。     

情绪对跨期决策的影响：来自单维占优模型的解释

跨期决策的研究表明, 积极情绪和消极情绪状态下的跨期决策行为存在显著差异。本研究从单维占优模型的角度, 揭示情绪影响跨期决策的过程机制。实验1通过诱发被试的积极和消极情绪, 发现积极情绪下被试的时间折扣率更低, 有更强的选择延迟选项的倾向。实验2运用“模拟天平任务”测量了跨期决策时的维度间差异比较, 检验单维占优模型对情绪影响跨期决策的解释性。结果发现, 维度间差异比较在情绪对跨期决策的影响中起中介作用。实验3a和实验3b分别运用时间和金钱启动策略操纵维度间差异比较过程, 再次验证单维占优模型的解释作用。 结果发现, 情绪对跨期决策的效应随着时间和金钱的启动而消失, 进一步支持了维度间差异比较的中介作用。本研究从决策过程的角度, 揭示了情绪影响跨期决策的心理机制, 并进一步为单维占优模型对跨期决策行为的解释性增加了支持性证据。     

Reasoning and concurrent timing: a study of the mechanisms underlying the effect of emotion on reasoning

Negative emotions typically have an adverse effect on reasoning, especially analytic or logical reasoning. This effect can be explained using an attentional framework in which emotion detracts limited-capacity cognitive resources which are required for reasoning. Another possibility is that the effect of emotion on reasoning is mediated by arousal, as previous research has shown that physiological arousal can be associated with decreased reasoning performance. In this research, we used a dual-task paradigm combining a syllogistic reasoning task and a time production task. Prospective timing allows to disentangle the effects of attention and arousal: time productions should lengthen if emotion takes up cognitive resources that are therefore not available for timing, whereas time productions should shorten if emotional reasoning results from increased arousal. Results from two experiments confirm the adverse impact of emotion on logical reasoning performance. Reasoning about emotional contents led to lengthened time productions, which suggests that the capture of limited cognitive resources is the main factor accounting for the adverse effect of emotion on reasoning and not arousal.     

情绪作为事件性前瞻记忆的附加线索:相反效价增强效应

使用前瞻记忆双任务实验范式,同时操纵当前任务与前瞻任务包含的情绪效价以及前瞻记忆的前瞻成分和回溯成分的情绪效价,考察双任务和两成分效价一致或相反条件对事件性前瞻记忆加工的影响。结果发现,与情绪效价一致时相比,双任务的效价相反时前瞻记忆更能正确执行,两成分情绪效价相反时前瞻成分完成更好。这种相反效价增强前瞻记忆的效应表明情绪作为附加线索影响了事件性前瞻记忆加工过程。     

诱发的积极情绪会促进多媒体学习吗?

近来, 教育心理学领域开始关注情绪因素对多媒体学习的影响, 其中诱发情绪逐渐成为研究者关注的指导设计形式。已有研究主要通过外部情绪诱发和内部情绪设计来考察诱发的积极情绪在学习过程中的作用, 并发现外部情绪诱发和内部情绪设计能够成功诱发积极情绪, 但由于情绪诱发方式的多样性和多媒体学习过程的复杂性, 诱发的积极情绪对学习效果的促进作用比较微弱。综述发现, 7项涉及外部情绪诱发的实验在学习结果上产生的效应量中值分别为d_保持 = -0.25, d_理解 = 0.04, d_迁移 = 0.30; 14项涉及内部情绪设计的实验在学习结果上产生的效应量中值分别为d_保持 = 0.27, d_理解 = 0.36, d_迁移 = 0.29。诱发的情绪对学习过程的主观体验影响很小。多媒体学习认知情感理论认为诱发的积极情绪会通过动机的中介作用进而促进学习; 相反, 认知负荷理论认为诱发的积极情绪会增加学习者的外在认知负荷从而阻碍学习。未来研究仍需关注情绪的操纵方法、效果评定以及潜在调节变量的作用等。     

青少年负性情绪事件性质判断偏向的情绪弹性和性别效应

研究以青少年学生为被试,采用测验和实验的方法考察了情绪弹性和性别变量对青少年在四类负性情绪事件性质的判断偏向上可能产生的影响。结果表明：（1）情绪弹性对青少年加工负性情绪事件信息时的判断偏向产生一定影响,低情绪弹性个体在面对与一般生活情境相关的负性情绪事件时,更倾向于从消极方面对事件的性质加以判断。（2）性别对青少年加工负性情绪事件信息时的判断偏向不产生实质性影响。     

Framing Persuasive Appeals: Episodic and Thematic Framing, Emotional Response, and Policy Opinion

Those seeking to frame political issues to their advantage recognize the power of emotional appeals. Yet the study of framing has focused mainly on the cognitive effects of framing rather than on its emotional effects. This study presents the results of two experiments designed to explore the effect of episodic and thematic framing on emotional response and policy opinion. Participants were randomly assigned to read a column arguing against mandatory minimum sentencing that employed either a thematic or one of two episodic frames featuring a woman who received a harsh sentence under the policy. Episodic framing was more emotionally engaging. Furthermore, the specific emotions elicited by the episodic frame—sympathy and pity for the woman featured in the column—were associated with increased opposition to mandatory minimum sentencing. Yet the thematic frame was actually more persuasive once this indirect effect of frame on emotional response was taken into account. The results are consistent with the conclusion that framing effects on policy opinion operate through both affective and cognitive channels. The theoretical and practical implications of the study are discussed.     

Assessing emotional processing difficulties in normotensive individuals with high and isolated blood pressure elevations

This study examined the effect of sense modality (auditory/visual) on emotional dampening (reduced responsiveness to emotions with elevation in blood pressure). Fifty‐six normotensive participants were assessed on tasks requiring labelling and matching of emotions in faces and voices. Based on median split of systolic and diastolic blood pressures (SBP and DBP, respectively), participants were divided into low BP, high BP and isolated BP groups. On emotion‐labelling tasks, analysis revealed reduced emotion recognition in the high BP than the low BP group. On emotion‐matching tasks, reduced emotion recognition was noted in high and also isolated BP group as compared to low BP group for the task that required matching a visual target with one of the four auditory distractors. Our findings show for the first time that even isolated elevations in either SBP or DBP may result in emotional dampening. Furthermore, the study highlights that the emotional dampening effect generalises to explicit processing (labelling) of emotional information in both faces and voices—and that these effects tentatively occur during more pragmatic and covert (matching) emotion recognition processes too. These findings require replication in clinical hypertensives.     

负性情绪背景和延迟对时间性前瞻记忆的影响

采用2（情绪效价：负性、中性）×2（延迟设置：无延迟、有延迟）的实验设计,探究负性情绪对时间性前瞻记忆的干扰效应。结果显示在无延迟条件下,负性情绪组的前瞻记忆成绩差于中性情绪组,负性情绪组的总时间监控次数和监控后期的时间监控次数均少于中性情绪组;在有延迟条件下,负性情绪组的前瞻记忆成绩和监控后期的时间监控次数与中性情绪组均无差异。结果说明负性情绪会干扰时间性前瞻记忆,而延迟可以消除这种干扰效应。     

Preserved re-experience of discrete emotions: Amnesia and executive function

Amnesic patients can re-experience emotions elicited by forgotten events, suggesting that brain systems for episodic and emotional memory are independent. However, the range of such emotional memories remains under-investigated (most studies employing just positive–negative emotion dyads), and executive function may also play a role in the re-experience of emotions. This is the first investigation of the intensity of the emotional re-experience of a range of discrete emotions (anger, fear, sadness, and happiness) for a group of amnesic patients. Twenty Korsakoff syndrome (KS) patients and 20 neurologically normal controls listened to four novel emotional vignettes selectively eliciting the four basic emotions. Emotional experience was measured using pen-and-paper Visual Analogue Mood Scales and episodic memory using verbal recollections. After 30 min, the recollection of stories was severely impaired for the patient group, but the emotional re-experience was no different from that of controls. Notably, there was no relationship between episodic recall and the intensity of the four emotions, such that even profoundly amnesic patients reported moderate levels of the target emotion. Exploratory analyses revealed negative correlations between the intensity of basic emotions and executive functions (e.g., cognitive flexibility and response inhibition) for controls but not patients. The results suggest that discrete emotions can be re-experienced independently of episodic memory, and that the re-experience of certain discrete emotions appears to be dampened by executive control. KS patients with absent or mild cognitive symptoms should benefit from emotion-regulation interventions aimed at reducing the recognized affective burden associated with their episodic memory deficit.     

Emotional Competence as a Mediator of the Relationship Between Internet Addiction and Negative Emotion in Young Adolescents in Hong Kong

Excessive use of the Internet in adolescents has been consistently found associated with multiple health concerns, especially negative emotions, and adversely affected one’s quality of life. While emotional competence is considered an important protective factor for youth development, its role in the relationship between Internet addiction and negative mental health outcomes has not been thoroughly investigated. The present study tested the mediation vs. moderation effects of emotional competence in the relation between Internet addiction and negative emotion in young adolescents based on 404 Hong Kong secondary school students (age = 12.4 ± 0.8 years). The results of structural equation modeling supported the mediation effect of emotional competence, but not its moderation effect. Internet addiction has both a direct influence on adolescents’ negative emotions, and an indirect effect through decreasing emotional competence. In particular, regulation of emotion appeared to be the only emotional competence dimension that mediates the relationship between Internet addiction and negative emotions. The findings suggest the importance of promoting emotional regulation competence to improve the quality of life of adolescents with Internet addiction problems.

     

Social anxiety and positive emotions: a prospective examination of a self-regulatory model with tendencies to suppress or express emotions as a moderating variable

The purpose of the present study was to examine social anxiety as a predictor of positive emotions using a short-term prospective design. We examined whether the effects of social anxiety on positive emotions are moderated by tendencies to openly express or supress emotions. Over the course of a 3-month interval, people with excessive social anxiety endorsed stable, low levels of positive emotions. In addition, people with low social anxiety who frequently display their emotions openly, whether negative or positive, reported the greatest increases in positive emotions. Similar results were found when using a measure of emotion suppression (low social anxiety and less tendency to rely on these types of regulatory acts led to the greatest positive emotions). These social anxiety main and interactive effects could not be attributed to depressive symptoms. Our findings suggest that relations between social anxiety and positive emotional experiences over time are best understood in the context of meaningful individual differences such as affect regulatory strategies.     

Valence-specific laterality effects in vocal emotion: interactions with stimulus type, blocking and sex

Valence-specific laterality effects have been frequently obtained in facial emotion perception but not in vocal emotion perception. We report a dichotic listening study further examining whether valence-specific laterality effects generalise to vocal emotions. Based on previous literature, we tested whether valence-specific laterality effects were dependent on blocked presentation of the emotion conditions, on the naturalness of the emotional stimuli, or on listener sex. We presented happy and sad sentences, paired with neutral counterparts, dichotically in an emotion localisation task, with vocal stimuli being preceded by verbal labels indicating target emotions. The measure was accuracy. When stimuli of the same emotion were presented as a block, a valence-specific laterality effect was demonstrated, but only in original stimuli and not morphed stimuli. There was a separate interaction with listener sex. We interpret our findings as suggesting that the valence-specific laterality hypothesis is supported only in certain circumstances. We discuss modulating factors, and we consider whether the mechanisms underlying those factors may be attentional or experiential in nature.     

中性抽象词和具体词情绪信息获得的差异

采用词汇迫选学习范式考察不同类型词汇获得情绪信息的认知机制。结果发现：（1）在迫选过程中与积极图片匹配的具体词汇喜好度显著高于与消极图片匹配的喜好度,而抽象词学习并未表现出这样的效应。（2）积极图片下被选择词汇的喜好度显著高于未被选择词汇的喜好度,而消极图片下被选择词汇与未被选择词汇的喜好度差异不显著。该结果表明具体词相较于抽象词更易获得相应情绪信息,积极情绪比消极情绪信息更易被习得。     

Comparing negative emotion differentiation in young and older individuals: A picture-based study

Life span theories suggest that emotional experiences become more complex (i.e., nuanced and differentiated) with age. Theoretically, the cause of this increased complexity has been proposed to be age-related changes in life contexts such as goals and daily stressors. Consequently, age may not affect emotional complexity in settings where the influence of age-specific life contexts is reduced. However, this hypothesis has yet to be explored. In the present study, we investigated one aspect of emotional complexity, namely emotion differentiation. Extending previous research, we assessed age-group differences in negative emotion differentiation between young and older adults in a controlled experimental setting. A sample of 114 young and 132 older adults rated their emotional response to 34 negative pictures according to intensity of four negative emotions. Based on these ratings, two indicators of emotion differentiation were calculated. The results revealed no significant age-group differences in negative emotion differentiation. The findings indicate stability in negative emotion differentiation with increasing age when the influence of life context is reduced. The findings are consistent with life span theories suggesting that developmental changes in emotional complexity occur largely as a result of age-related changes in life contexts rather than more stable age-related changes in individual characteristics.     

Ego Depletion as a Measure of Emotion Processing Deficits among MUS Patients

Previous studies have found a link between emotion processing deficits and medically unexplained physical symptoms (MUS). The majority of previous studies have used self-report measures of emotional processing, with the majority focusing on alexithymia, and have produced inconsistent and contradictory results. In the present study, we investigated the role of emotion-processing deficits in MUS by assessing emotion regulation performance and the effects of performance on ego depletion. Participants with high or low levels of self-reported MUS watched emotion-evoking videos under instructions to allow or suppress their emotional reactions, and then performed an anagram task to measure their effort and perseverance. Contrary to the research with self-report measures, experimental analysis of emotion-processing revealed that MUS is correlated with the inability to regulate negative emotions. Unexpected self-regulatory tendencies of the participants with high symptom levels were discussed.     

Knowing me,knowing you: emotion differentiation in oneself is associated with recognition of others’ emotions

ABSTRACT

Previous research has found that individuals vary greatly in emotion differentiation, that is, the extent to which they distinguish between different emotions when reporting on their own feelings. Building on previous work that has shown that emotion differentiation is associated with individual differences in intrapersonal functions, the current study asks whether emotion differentiation is also related to interpersonal skills. Specifically, we examined whether individuals who are high in emotion differentiation would be more accurate in recognising others’ emotional expressions. We report two studies in which we used an established paradigm tapping negative emotion differentiation and several emotion recognition tasks. In Study 1 (N?=?363), we found that individuals high in emotion differentiation were more accurate in recognising others’ emotional facial expressions. Study 2 (N?=?217), replicated this finding using emotion recognition tasks with varying amounts of emotional information. These findings suggest that the knowledge we use to understand our own emotional experience also helps us understand the emotions of others.
