Perception of facial expressions of emotion during binocular rivalry.

Binocular rivalry is the perceptual alternation between two incompatible stimuli presented simultaneously but to each eye separately. The observer's perception switches back and forth between the two stimuli that are competing for perceptual dominance. In two studies, pictures of emotional faces (disgust and happy) were pitted against each other or against pictures of faces with neutral expressions. Study 1 demonstrated that (a) emotional facial expressions predominate over neutral expressions, and (b) positive facial expressions predominate over negative facial expression (i.e., positivity bias). Study 2 examined individual differences in emotional predominance and positivity bias during binocular rivalry. Although the positivity bias was not affected by the levels of depressive symptoms, results demonstrated that emotional predominance diminished as the level of depressive symptoms increased. These results indicate that individuals who report more depressive symptoms compared to their less depressed counterparts tend to assign more meaning to neutral faces.

Disgust sensitivity predicts intuitive disapproval of gays.

Two studies demonstrate that a dispositional proneness to disgust (“disgust sensitivity”) is associated with intuitive disapproval of gay people. Study 1 was based on previous research showing that people are more likely to describe a behavior as intentional when they see it as morally wrong (see Knobe, 2006, for a review). As predicted, the more disgust sensitive participants were, the more likely they were to describe an agent whose behavior had the side effect of causing gay men to kiss in public as having intentionally encouraged gay men to kiss publicly—even though most participants did not explicitly think it wrong to encourage gay men to kiss in public. No such effect occurred when subjects were asked about heterosexual kissing. Study 2 used the Implicit Association Test (IAT; Nosek, Banaji, & Greenwald, 2006) as a dependent measure. The more disgust sensitive participants were, the more they showed unfavorable automatic associations with gay people as opposed to heterosexuals.

Strategic automation of emotion regulation.

As implementation intentions are a powerful self-regulation tool for thought and action (meta-analysis by P. M. Gollwitzer & P. Sheeran, 2006), the present studies were conducted to address their effectiveness in regulating emotional reactivity. Disgust- (Study 1) and fear- (Study 2) eliciting stimuli were viewed under 3 different self-regulation instructions: the goal intention to not get disgusted or frightened, respectively, this goal intention furnished with an implementation intention (i.e., an if-then plan), and a no-self-regulation control group. Only implementation-intention participants succeeded in reducing their disgust and fear reactions as compared to goal-intention and control participants. In Study 3, electrocortical correlates (using dense-array electroencephalography) revealed differential early visual activity in response to spider slides in ignore implementation-intention participants, as reflected in a smaller P1. Theoretical and applied implications of the present findings for emotion regulation via implementation intentions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The voice conveys specific emotions: Evidence from vocal burst displays.

Studies of emotion signaling inform claims about the taxonomic structure, evolutionary origins, and physiological correlates of emotions. Emotion vocalization research has tended to focus on a limited set of emotions: anger, disgust, fear, sadness, surprise, happiness, and for the voice, also tenderness. Here, we examine how well brief vocal bursts can communicate 22 different emotions: 9 negative (Study 1) and 13 positive (Study 2), and whether prototypical vocal bursts convey emotions more reliably than heterogeneous vocal bursts (Study 3). Results show that vocal bursts communicate emotions like anger, fear, and sadness, as well as seldom-studied states like awe, compassion, interest, and embarrassment. Ancillary analyses reveal family-wise patterns of vocal burst expression. Errors in classification were more common within emotion families (e.g., ’self-conscious,’ ’pro-social’) than between emotion families. The three studies reported highlight the voice as a rich modality for emotion display that can inform fundamental constructs about emotion.

Working memory capacity and the self-regulation of emotional expression and experience.

This research examined the relationship between individual differences in working memory capacity and the self-regulation of emotional expression and emotional experience. Four studies revealed that people higher in working memory capacity suppressed expressions of negative emotion (Study 1) and positive emotion (Study 2) better than did people lower in working memory capacity. Furthermore, compared to people lower in working memory capacity, people higher in capacity more capably appraised emotional stimuli in an unemotional manner and thereby experienced (Studies 3 and 4) and expressed (Study 4) less emotion in response to those stimuli. These findings indicate that cognitive ability contributes to the control of emotional responding. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Neural responses to facial and vocal expressions of fear and disgust

Neuropsychological studies report more impaired responses to facial expressions of fear than disgust in people with amygdala lesions, and vice versa in people with Huntington's disease. Experiments using functional magnetic resonance imaging (fMRI) have confirmed the role of the amygdala in the response to fearful faces and have implicated the anterior insula in the response to facial expressions of disgust. We used fMRI to extend these studies to the perception of fear and disgust from both facial and vocal expressions. Consistent with neuropsychological findings, both types of fearful stimuli activated the amygdala. Facial expressions of disgust activated the anterior insula and the caudate-putamen; vocal expressions of disgust did not significantly activate either of these regions. All four types of stimuli activated the superior temporal gyrus. Our findings therefore (i) support the differential localization of the neural substrates of fear and disgust; (ii) confirm the involvement of the amygdala in the emotion of fear, whether evoked by facial or vocal expressions; (iii) confirm the involvement of the anterior insula and the striatum in reactions to facial expressions of disgust; and (iv) suggest a possible general role for the perception of emotional expressions for the superior temporal gyrus.     

Changes in the sensitivity to appetitive and aversive arousal across adulthood.

In 2 cross-sectional studies, the authors examined age-related differences in the evaluation of emotional stimuli in 2 community samples, with participants ranging in age from young to older adulthood (18–81 years old). Pictures of the International Affective Picture System were used in Study 1, and written verbs were used in Study 2. Participants rated these stimuli along the 2 major affective dimensions of hedonic valence and emotional arousal, thus yielding a 2-dimensional affective space for each participant. Young adults showed the expected pattern of 2 distinct clusters of stimuli in this space, representing increasing pleasantness (appetitive activation) and unpleasantness (aversive activation) with increasing emotional arousal. In contrast, for older adults, emotional valence and arousal ratings were linearly related: Low-arousing stimuli were rated as most pleasant, and high-arousing stimuli were rated as most unpleasant. When regressed on age, these changes revealed a gradual decrease of appetitive activation (i.e., the relationship between pleasure and arousal) across adulthood and a linear increase in aversive activation (i.e., the relationship between displeasure and arousal). These results extend previous work on emotional development, adding information as to the role of emotional intensity for affective experience in different age groups.

Emotional expression and physiology in European Americans and Hmong Americans.

Ethnographic and clinical observations suggest that Asians are less expressive than European Americans. To examine whether this difference emerged in online emotional responding, 50 Hmong Americans (HAs) and 48 European Americans (EAs) were asked to relive past episodes of intense happiness, pride, love, anger, disgust, and sadness. Facial behavior and physiological reactivity were measured. For most emotions, more cultural similarities than differences were found. There were some exceptions: During happiness, fewer HAs than EAs showed non-Duchenne smiles (i.e., "social" smiles), despite similarities in reported emotional experience and physiological reactivity. Within-group differences between "less Hmong" and "more Hmong" HAs were also found. Implications of these findings for our understanding of culture-emotion relations are discussed.

Narcissism and romantic attraction.

A model of narcissism and romantic attraction predicts that narcissists will be attracted to admiring individuals and highly positive individuals and relatively less attracted to individuals who offer the potential for emotional intimacy. Five studies supported this model. Narcissists, compared with nonnarcissists, preferred more self-oriented (i.e., highly positive) and less other-oriented (i.e., caring) qualities in an ideal romantic partner (Study 1). Narcissists were also relatively more attracted to admiring and highly positive hypothetical targets and less attracted to caring targets (Studies 2 and 3). Indeed, narcissists displayed a preference for highly positive-noncaring targets compared with caring but not highly positive targets (Study 4). Finally, mediational analyses demonstrates that narcissists' romantic attraction is, in part, the result of a strategy for enhancing self-esteem (Study 5).

Rejection sensitivity and children's interpersonal difficulties

Some children respond to social rejection in ways that undermine their relationships, whereas others respond with more equanimity. This article reports 3 studies that test the proposition that rejection sensitivity--the disposition to defensively (i.e., anxiously or angrily) expect, readily perceive, and overreact to social rejection--helps explain individual differences in response to social rejection. Data were from urban, minority (primarily Hispanic and African American) fifth to seventh graders. Study 1 describes the development of a measure of rejection sensitivity for children. Study 2 provides experimental evidence that children who angrily expected rejection showed heightened distress following an ambiguously intentioned rejection by a peer. Study 3 shows that rejection sensitive children behaved more aggressively and experienced increased interpersonal difficulties and declines in academic functioning over time.     

Le développement de la reconnaissance des expressions faciales des émotions chez l'enfant.

Studied the development of the recognition of emotional facial expressions in children and of the factors influencing recognition accuracy. 80 elementary school students (aged 5–8 yrs) were asked to identify the emotions expressed in a series of facial photographs. Recognition performances were analyzed in relation to the type of emotion expressed (i.e., happiness, fear, anger, surprise, sadness, or disgust) and the intensity of the emotional expression. Age differences were determined. (English abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cognitive correlates of emotional traits: Perceptions of self and others.

Two studies examined how individuals' perceptions of self and others are associated with different emotional traits. Study 1 (N = 386) used structural equation modeling of questionnaire data to examine the relations between emotional traits (i.e., affect intensity, affect variability, and trait pleasant and unpleasant affect) and self- and other-perceptions (i.e., self-instability, self-esteem, other-instability, and perceived treatment by others). Study 2 (N = 99) used path analyses of data collected using an event sampling method in which online measures of emotional experiences (i.e., intensity, frequency, and variability of pleasant and unpleasant affect) as well as perceptions of self and others (i.e., self-instability, self-esteem, other-instability, perceived treatment by others) were collected. The strongest and most consistent finding was that affect variability was associated with both self- and other-instability. The results linking affect intensity with self- and other-instability were limited to negative intensity. There was also evidence of pleasant affect being associated with both self-esteem and perceived treatment by others, and unpleasant affect being associated with self-esteem and other-instability.

Arithmetic Split Effects Reflect Strategy Selection: An Adult Age Comparative Study in Addition Comparison and Verification Tasks.

We tested whether split effects in arithmetic (i.e., better performance on large-split problems, like 3 + 8 = 16, than on small-split problems, like 3 + 8 = 12) reflect decision processing or strategy selection. To achieve this end, we tested performance of younger and older adults, matched on arithmetic skills, on two arithmetic tasks: the addition/number comparison task (e.g., 4 + 8 ? 13; which item is the larger?) and in the inequality verification task (e.g., 4 + 8     

Proud Americans and lucky Japanese: Cultural differences in appraisal and corresponding emotion.

Appraisal theories of emotion propose that the emotions people experience correspond to their appraisals of their situation. In other words, individual differences in emotional experiences reflect differing interpretations of the situation. We hypothesized that in similar situations, people in individualist and collectivist cultures experience different emotions because of culturally divergent causal attributions for success and failure (i.e., agency appraisals). In a test of this hypothesis, American and Japanese participants recalled a personal experience (Study 1) or imagined themselves to be in a situation (Study 2) in which they succeeded or failed, and then reported their agency appraisals and emotions. Supporting our hypothesis, cultural differences in emotions corresponded to differences in attributions. For example, in success situations, Americans reported stronger self-agency emotions (e.g., proud) than did Japanese, whereas Japanese reported a stronger situation-agency emotion (lucky). Also, cultural differences in attribution and emotion were largely explained by differences in self-enhancing motivation. When Japanese and Americans were induced to make the same attribution (Study 2), cultural differences in emotions became either nonsignificant or were markedly reduced.

Social and physical anhedonia and valence and arousal aspects of emotional experience.

Two studies examined whether self-reported anhedonia is associated with 2 facets of emotional experience, valence and arousal. In Study 1, in multiple assessments of emotional experience (e.g., naturalistic and lab contexts and social and nonsocial situations), people with elevated social anhedonia (n = 40) reported less intensity of positive affect than both controls (n = 30) and people with elevated perceptual aberration-magical ideation (n = 29). Social anhedonia was also associated with providing less emotional content when describing what it is like to experience positive situations. In contrast, both social anhedonia and perceptual aberration-magical ideation were associated with increased frequency of negative affect for their daily experiences. Moreover, social anhedonia was not associated with a decrease specifically in high-arousal emotions. In Study 2 (n = 339), social and physical anhedonia (but not perceptual aberration-magical ideation) were again associated with decreased self-reported positive affect to lab stimuli. In these studies, results were not statistically accounted for by personality, current mood, or current distress. Overall, results suggest anhedonia may be associated with a general decrease in self-reported positive affect intensity. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Affective and cognitive meta-bases of attitudes: Unique effects on information interest and persuasion.

The authors investigated the predictive utility of people's subjective assessments of whether their evaluations are affect- or cognition driven (i.e., meta-cognitive bases) as separate from whether people's attitudes are actually affect- or cognition based (i.e., structural bases). Study 1 demonstrated that meta-bases uniquely predict interest in affective versus cognitive information above and beyond structural bases and other related variables (i.e., need for cognition and need for affect). In Study 2, meta-bases were shown to account for unique variance in attitude change as a function of appeal type. Finally, Study 3 showed that as people became more deliberative in their judgments, meta-bases increased in predictive utility, and structural bases decreased in predictive utility. These findings support the existence of meta-bases of attitudes and demonstrate that meta-bases are distinguishable from structural bases in their predictive utility.

Dimensions of conflict frame: Disputant interpretations of conflict.

This research was conducted to uncover and define disputant cognitive interpretations of conflict. In Study 1, 31 disputants and 9 mediators were asked to describe a conflict with which they were currently associated. Multidimensional scaling techniques were used to inductively derive the dimensions necessary to represent people's cognitive interpretations of conflict (i.e., dimensions of conflict frame). The resulting configuration consisted of three dimensions: (a) relationship versus task, (b) emotional versus intellectual, and (c) compromise versus win. In comparison with disputants, mediator interpretations were more likely to be viewed by disputants in relationship, compromise terms. Study 2 replicated the multidimensional scaling findings of Study 1 using a different subject population (i.e., undergraduate students).

Contamination fear and effects of disgust on distress in a public restroom.

The present study examined the effect of a disgust mood induction on self-reported distress during exposure to 5 stimuli with increasing potential for contagion in a public restroom among contamination fearful individuals. Participants were 36 adults identified as high in contamination fear (HCF) and 47 adults identified as low in contamination fear (LCF) who were randomly assigned to either a disgust or neutral emotion induction condition. Consistent with predictions, HCF participants exhibited significantly more distress than LCF participants during exposure to the sources of contagion in the restroom. However, this main effect was moderated by type of mood induction and task difficulty. Specifically, significant differences in distress between HCF and LCF participants emerged only for stimuli with low potential for contagion (i.e., touching the inside of the bathroom sink) in the disgust condition, whereas such group differences in distress emerged only for stimuli with a relatively high potential for contagion (i.e., touching the inside of the bathroom toilet) in the neutral condition. The implications of these findings for better understanding the functional role of disgust in contamination fear are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Me against myself: Motivational conflicts and emotional development in adulthood.

Two studies investigated adult age differences in the frequency and emotional consequences of motivational conflicts (i.e., feeling that one wants to or should do something else in a given situation). Study 1 compared younger and older adults. Study 2 included a more age-heterogeneous sample ranging from 20 to 70 years. Data were obtained using diary and experience-sampling methods. Multilevel regression showed that motivational conflict was associated with lower emotional well-being. With age, the frequency of motivational conflict decreased, while emotional well-being increased. Importantly, the age-related decrease in motivational conflicts partly accounted for the age-related increase in emotional well-being. Findings were consistent across studies and robust after the authors controlled for age differences in a number of control variables including time use. The authors conclude that an age-related decrease in motivational conflicts in daily life may be among the factors underlying the positive development of emotional well-being into older adulthood.
