Effects of emotion on oxytocin,prolactin, and ACTH in women

Research on both non-human mammals and humans has raised interest in the role that oxytocin may play in human attachment and attachment-related emotions. This study examined changes in plasma oxytocin, prolactin, and ACTH concentrations in response to laboratory-induced positive and negative emotions related to close, interpersonal relationships. Participants were 32 female volunteers recruited from university communities. During positive emotion induction, oxytocin decreased over time (F(1,3) = 4.41, p < 0.007), prolactin increased (F(1,3) = 4.80, p < 0.004) and ACTH remained constant. During negative emotion induction, prolactin levels increased (F(1,3) = 2.81, p < 0.05), ACTH decreased only after the induction terminated (F(1,3) = 4.02, p < 0.01) and oxytocin remained constant. While oxytocin decreased during positive emotion, this finding contrasted previous research that showed decreases in response to negative emotion. In conclusion, plasma oxytocin levels were not reliably altered by positive or negative emotion induction. While prolactin and ACTH were expected to decrease over time due to diurnal variation, they instead either increased or remained level during emotion induction, or decreased only after the induction. Overall, the degree of change in circulating hormones in response to happy and sad emotions was very small and possibly not functionally significant.     

Reappraising faces: effects on accountability appraisals,self-reported valence,and pupil diameter

Many of our emotions arise in social contexts, as we interact with and learn about others. What is not yet clear, however, is how such emotions unfold when we either react to others or attempt to regulate our emotions. To address this issue, 30 healthy volunteers reacted to or reappraised positive or negative information that was paired with neutral faces. While they were doing this task, we assessed pupillary responses. We also asked participants to provide ratings of accountability and experienced emotion. Findings indicated that appraised accountability increased in response to emotional information, and changes in accountability were associated with commensurate changes in valence reports and increased pupil diameter. During reappraisal, accountability and emotion decreased, but pupil diameter increased. The findings highlight the importance of accountability appraisals during the generation and regulation of emotional reactions to others, while also documenting pupillary increases during emotional reactivity and regulation.     

Dimensions of Filipino Negative Social Emotions

The interpretation of emotions as cultural categories is possible by investigating emotional experience within the social situations which were expected to produce them. This is afforded by a componential framework of analysis. In this study, 15 Filipino social negative emotion words are clustered and subjected to a componential analysis in focus group discussions. The emotion components that were used to differentiate each cluster were appraisal processes, focal events, emotion regulation, action tendencies and relationships with the other. Three emotion clusters were identified varying in terms of degree of intensity. The highest intensity was associated with emotions that invoke a moral dimension to the actions of the other. The other two clusters are lesser in intensity and involve putting responsibility on the self for experiencing the emotions. The emotions in all clusters are associated with varying forms of changes in the relationships with the other.     

Structure of the Indonesian Emotion Lexicon

Based on a prototype approach to emotion concepts, two studies were conducted: (1) to identify the mental state words that Indonesian speakers are most certain name emotions ( perasaan hati ) and (2) to map the hierarchical and family-resemblance structure of the top 124 emotion concepts. As in an earlier study of emotion terms in American English (Shaver, Schwartz, Kirson, & O'Connor, 1987), cluster analysis of sorting data collected in Indonesia revealed five basic-level emotion categories: cinta (love), senang (happiness), marah (anger), kawatir/takut (anxiety/fear), and sedih (sadness). Also in line with the American results, the five basic-level categories formed two large categories at the superordinate level: positive emotions and negative emotions. Each of the five basic-level categories contained several subordinate-level categories, totaling 31 in all. The results suggest that the emotion lexicons, and corresponding conceptualizations of the emotion domain, in Indonesia and the U.S.A. are similar at the superordinate and basic levels but somewhat variable at the subordinate level. This outcome – like other kinds of psychological research on emotions and emotion concepts – suggests that the gross structure of representations of the emotion domain are similar worldwide, perhaps for biological reasons, but that different cultures make different fine-grained distinctions and emphasize different subordinate-level emotion concepts.     

Increasing negative emotions by reappraisal enhances subsequent cognitive control: A combined behavioral and electrophysiological study

To what degree do cognitively based strategies of emotion regulation impact subsequent cognitive control? Here, we investigated this question by interleaving a cognitive task with emotion regulation trials, where regulation occurred through cognitive reappraisal. In addition to obtaining self-reports of emotion regulation, we used the late positive potential (LPP) of the event-related brain potential as an objective index of emotion regulation. On each trial, participants maintained, decreased, or increased their emotional response to an unpleasant picture and then responded to a Stroop stimulus. Results revealed that (1) the magnitude of the LPP was decreased with reappraisal instructions to decrease negative emotion and were enhanced with reappraisal instructions to increase negative emotion; (2) after cognitive reappraisal was used to increase the intensity of negative emotion, RT interference in the subsequent Stroop trial was significantly reduced; and (3) increasing negative emotions by reappraisal also modulated the cognitive control-related sustained potential. These results suggest that increasing negative emotions by cognitive reappraisal heightens cognitive control, which may be sustained for a short time after the regulation event.     

The Effects of Anxiety and Depressive Symptoms on Daily Positive Emotion Regulation

Individuals with anxiety and depressive symptoms exhibit disturbances in positive emotion regulation, which may hinder full recovery. By comparison, individuals with strong beliefs regarding their capacity to “savor” or maintain positive emotions (i.e., savoring beliefs) display more adaptive positive emotion regulation. The present daily diary study explores three momentary processes involved in positive emotion regulation, namely positive emotion reactivity, regulatory goals, and regulatory effectiveness, and examines the comparative effects of baseline anxiety and depressive symptoms versus savoring beliefs on such processes in real-life contexts. A sample of 164 nonclinical undergraduates provided baseline measures of anxiety and depressive symptom severity and savoring beliefs prior to completing 14 daily assessments of positive emotions and emotion regulatory responses to daily positive events. Results indicated that higher baseline anxiety and depressive symptom severity were associated with decreased positive emotion reactivity and increased down-regulation of positive emotions; higher baseline savoring beliefs were associated with increased positive emotion reactivity, decreased down-regulation and increased up-regulation of positive emotions. Potential clinical implications are discussed.     

Mapping emotions through time: how affective trajectories inform the language of emotion

The words used to describe emotions can provide insight into the basic processes that contribute to emotional experience. We propose that emotions arise partly from interacting evaluations of one's current affective state, previous affective state, predictions for how these may change in the future, and the experienced outcomes following these predictions. These states can be represented and inferred from neural systems that encode shifts in outcomes and make predictions. In two studies, we demonstrate that emotion labels are reliably differentiated from one another using only simple cues about these affective trajectories through time. For example, when a worse-than-expected outcome follows the prediction that something good will happen, that situation is labeled as causing anger, whereas when a worse-than-expected outcome follows the prediction that something bad will happen, that situation is labeled as causing sadness. Emotion categories are more differentiated when participants are required to think categorically than when participants have the option to consider multiple emotions and degrees of emotions. This work indicates that information about affective movement through time and changes in affective trajectory may be a fundamental aspect of emotion categories. Future studies of emotion must account for the dynamic way that we absorb and process information.     

Do Dynamic Facial Expressions Convey Emotions to Children Better Than Do Static Ones?

Past research has shown that children recognize emotions from facial expressions poorly and improve only gradually with age, but the stimuli in such studies have been static faces. Because dynamic faces include more information, it may well be that children more readily recognize emotions from dynamic facial expressions. The current study of children (N = 64, aged 5–10 years old) who freely labeled the emotion conveyed by static and dynamic facial expressions found no advantage of dynamic over static expressions; in fact, reliable differences favored static expressions. An alternative explanation of gradual improvement with age is that children's emotional categories change during development from a small number of broad emotion categories to a larger number of narrower categories—a pattern found here with both static and dynamic expressions.     

Structure of the Basque emotion lexicon

Using a prototype approach to emotion concepts, two studies were conducted in the Basque Country, where an ancient non-Indo-European language is still spoken, to identify the mental state words that Basque speakers are most certain name emotions (emozioak) and to map the hierarchical and family resemblance structure of the most prototypical 124 emotion concepts. Cluster analysis of sorting data collected in the Basque Country revealed five basic level emotion categories similar to those found in American English and Indonesian (love, happiness, anger, sadness, and fear) as well as five other small positive emotion categories. All major categories found at the basic level contained several terms that are not traceable to Romance languages. Also in line with the American and Indonesian results, the basic level categories in Basque fell within two large superordinate categories: positive and negative emotions. Each of the five large basic level categories contained several subordinate level categories. The results suggest that the emotion lexicons, and corresponding conceptualisations of the emotion domain, in the Basque Country, Indonesia, and the US are similar, although there are some important differences.     

The brain basis of emotion: a meta-analytic review

Researchers have wondered how the brain creates emotions since the early days of psychological science. With a surge of studies in affective neuroscience in recent decades, scientists are poised to answer this question. In this target article, we present a meta-analytic summary of the neuroimaging literature on human emotion. We compare the locationist approach (i.e., the hypothesis that discrete emotion categories consistently and specifically correspond to distinct brain regions) with the psychological constructionist approach (i.e., the hypothesis that discrete emotion categories are constructed of more general brain networks not specific to those categories) to better understand the brain basis of emotion. We review both locationist and psychological constructionist hypotheses of brain-emotion correspondence and report meta-analytic findings bearing on these hypotheses. Overall, we found little evidence that discrete emotion categories can be consistently and specifically localized to distinct brain regions. Instead, we found evidence that is consistent with a psychological constructionist approach to the mind: A set of interacting brain regions commonly involved in basic psychological operations of both an emotional and non-emotional nature are active during emotion experience and perception across a range of discrete emotion categories.     

医学生情绪调节方式的干预实验

采用《情绪调节习惯问卷》对某医大296名大二学生进行调查。选取其中情绪调节方式较为单一的34名学生进行干预实验,再用《情绪调节习惯问卷》和《大学生一般学业情绪问卷》考察干预效果。结果表明,医学生四种情绪调节方式（包括忽视、重视、抑制、宣泄）的使用较为均衡。实验组增加了对负性情绪的宣泄和抑制策略,其焦虑、厌烦和愉快学业情绪发生了积极转变;记忆组改善了记忆策略的同时其焦虑、羞愧和兴趣学业情绪发生了积极转变。说明情绪调节策略训练和记忆策略训练均可使医学生一些学业情绪发生积极转变,但前者效果较优。     

Rose-colored glasses gone too far? Mania symptoms predict biased emotion experience and perception in couples

The present study investigated how symptoms of mania—associated with heightened and persistent positive emotion—influence emotion experience and perception during distressing social interactions, whereby the experience of heightened positive emotion may not be socially adaptive. Specifically, mania symptoms were assessed via a validated self-report measure, and used to predict emotion experience and perception during a naturalistic conversation between romantic couples about a time of distress and suffering (N = 68 dyads). Results indicated that mania symptoms were associated with increased positive and decreased negative emotion experience and perception between couples, as well as decreased empathic accuracy for partners’ negative but not positive emotions. These findings suggest that mania symptoms may be associated with “rose-colored” glasses characterized by a positively biased emotional experience and outward perception even during perhaps the most intimate and distressing social situations.     

Acceptability and suppression of negative emotion in anxiety and mood disorders

The present study investigated perceived acceptability and suppression of negative emotion in participants with anxiety and mood disorders. Sixty participants with these disorders and 30 control participants watched an emotion-provoking film and completed self-report measures of their experience and regulation of emotions. The film elicited similar increases in negative emotion for clinical and nonclinical participants; however, clinical participants judged their resulting emotions as less acceptable and suppressed their emotions to a greater extent. The higher level of suppression in the clinical group was attributable to females in the clinical group suppressing their emotions more than females in the nonclinical group. For all participants, high levels of suppression were associated with increased negative emotion during the film and during a postfilm recovery period. Further analyses showed that appraising emotions as unacceptable mediated the relationship between negative emotion intensity and use of suppression in the clinical group. This study extends the literature on emotion regulation to a clinical sample and suggests that judging emotions as unacceptable and suppressing emotions may be important aspects of the phenomenology of emotional disorders.     

Beyond depression: Gender differences in normal adolescents' emotional experiences

Adolescents (N=262) in the fifth, seventh, ninth, and eleventh grades reported the frequency, intensity, and duration of their experiences of 12 emotions and the situations during which they occurred. The first three scales of emotion combined to produce the emotion saliency score. Girls reported higher saliences of surprise, sad, self-hostility, shame, shy, and guilt. Boys reported higher saliency of contempt. Factor analysis of the salient emotions retained the same three factors for both genders: positive emotion, inner-passive, and outer-hostile negative emotions. The loadings for surprise, sad, and anger on each factor suggested within factor gender differences. Most salient emotions were experienced with peers; however, boys experienced both surprise and sadness more often when alone than did girls. There were gender differences in most emotion categories on the events associated with salient emotions. Boys found activities and achievement, and girls found affiliation, to be emotionally salient. These data suggest that gender differences in emotion are pervasive rather than confined to depressive emotion and include differences in the organizational properties of emotion.This study was based upon data collected for the first author's dissertation under the direction of the second author. Preliminary analyses were presented at Eastern Psychological Association, Crystal City, Maryland, 1987.     

The perception of changing emotion expressions

The utility of recognising emotion expressions for coordinating social interactions is well documented, but less is known about how continuously changing emotion displays are perceived. The nonlinear dynamic systems view of emotions suggests that mixed emotion expressions in the middle of displays of changing expressions may be decoded differently depending on the expression origin. Hysteresis is when an impression (e.g., disgust) persists well after changes in facial expressions that favour an alternative impression (e.g., anger). In expression changes based on photographs (Study 1) and avatar images (Studies 2a-c, 3), we found hystereses particularly in changes between emotions that are perceptually similar (e.g., anger-disgust). We also consistently found uncertainty (neither emotion contributing to the mixed expression was perceived), which was more prevalent in expression sequences than in static images. Uncertainty occurred particularly in changes between emotions that are perceptually dissimilar, such as changes between happiness and negative emotions. This suggests that the perceptual similarity of emotion expressions may determine the extent to which hysteresis and uncertainty occur. Both hysteresis and uncertainty effects support our premise that emotion decoding is state dependent, a characteristic of dynamic systems. We propose avenues to test possible underlying mechanisms.     

Embodied emotion concepts: How generating words about pride and disappointment influences posture

Embodiment theories predict that activating conceptual knowledge about emotions can be accompanied by re‐experiencing bodily states, since simulations of sensory, motor, and introspective experiences form the foundation of conceptual representations of emotion. In the present study, we examine whether the activation of the specific emotion concepts of pride and disappointment are embodied in the sense that they are accompanied by changes in posture. Participants generated words associated with pride and disappointment while posture height was measured. Results show that during the generation of disappointment words participants decreased their posture height more than when participants generated pride words. This finding suggests that the activation of conceptual knowledge about disappointment can lead to a spontaneous expression of the associated body posture. In contrast to posture changes along the vertical axis, movement along the horizontal axis was not influenced by concept activation. In addition to bodily simulation the data also indicated introspective simulation, since feelings of disappointment increased after generating disappointment words. The current study provides the first evidence for the claim that the activation of conceptual knowledge about emotion can instantiate spontaneous simulations at a behavioral level.
