Threat advantage: Perception of angry and happy dynamic faces across cultures

The current study tested whether the perception of angry faces is cross-culturally privileged over that of happy faces, by comparing perception of the offset of emotion in a dynamic flow of expressions. Thirty Chinese and 30 European-American participants saw movies that morphed an anger expression into a happy expression of the same stimulus person, or vice versa. Participants were asked to stop the movie at the point where they ceased seeing the initial emotion. As expected, participants cross-culturally continued to perceive anger longer than happiness. Moreover, anger was perceived longer in in-group than in out-group faces. The effects were driven by female rather than male targets. Results are discussed with reference to the important role of context in emotion perception.

Age-related differences in emotion matching are limited to low intensity expressions

Multi-label tasks confound age differences in perceptual and cognitive processes. We examined age differences in emotion perception with a technique that did not require verbal labels. Participants matched the emotion expressed by a target to two comparison stimuli, one neutral and one emotional. Angry, disgusted, fearful, happy, and sad facial expressions of varying intensity were used. Although older adults took longer to respond than younger adults, younger adults only outmatched older adults for the lowest intensity disgust and fear expressions. Some participants also completed an identity matching task in which target stimuli were matched on personal identity instead of emotion. Although irrelevant to the judgment, expressed emotion still created interference. All participants were less accurate when the apparent difference in expressive intensity of the matched stimuli was large, suggesting that salient emotion cues increased difficulty of identity matching. Age differences in emotion perception were limited to very low intensity expressions.     

Effects of induced sad mood on facial emotion perception in young and older adults

Older adults perceive less intense negative emotion in facial expressions compared to younger counterparts. Prior research has also demonstrated that mood alters facial emotion perception. Nevertheless, there is little evidence which evaluates the interactive effects of age and mood on emotion perception. This study investigated the effects of sad mood on younger and older adults’ perception of emotional and neutral faces. Participants rated the intensity of stimuli while listening to sad music and in silence. Measures of mood were administered. Younger and older participants’ rated sad faces as displaying stronger sadness when they experienced sad mood. While younger participants showed no influence of sad mood on happiness ratings of happy faces, older adults rated happy faces as conveying less happiness when they experienced sad mood. This study demonstrates how emotion perception can change when a controlled mood induction procedure is applied to alter mood in young and older participants.     

Inhibiting Facial Expressions: Limitations to the Voluntary Control of Facial Expressions of Emotion

Recently, A. J. Fridlund (e.g., 1994) and others suggested that facial expressions of emotion are not linked to emotion and can be completely accounted for by social motivation. To clarify the influence of social motivation on the production of facial displays, we created an explicit motivation by using facial inhibition instructions. While facial electromyographic activity was recorded at three sites, participants saw humorous video stimuli in two conditions (inhibition, spontaneous) and neutral stimuli in a spontaneous condition. Participants showed significantly more EMG activity in the cheek region and less EMG activity in the brow region when they tried to completely inhibit amused expressions as compared with the neutral control task. Our results suggest that explicit motivation in the sense of voluntary control is not sufficient to mask the effects of spontaneous facial activation linked to humorous stimuli.     

Sociosexuality and face perception: Unrestricted sexual orientation facilitates sensitivity to female facial cues

Across two studies, sexually unrestricted men and women showed heightened sensitivity to female facial symmetry (a signal of genetic fitness) and female sexual receptivity (happy facial expressions). In Study 1, individuals assessed the attractiveness of male and female targets of varying facial symmetry. Sexually unrestricted men and women, compared to their sexually restricted counterparts, showed a stronger symmetry advantage in attractiveness ratings for female targets, an indication of greater sensitivity to facial symmetry. Study 2 asked participants to discriminate between genuine (Duchenne) and deceptive smiles on both male and female faces. Results indicated that sexually unrestricted men and women, compared to sexually restricted individuals, were better able to discriminate between these actual and deceptive signals of receptivity for female targets. Neither study found any relationship between sociosexual orientation and the perception of male targets. These results suggest that sexually unrestricted individuals are attuned to reproductively-relevant cues in female faces.     

Relationship status moderates avoidant attachment differences in positive emotion decoding accuracy

We investigated attachment differences in the perception of facial emotion expressions. Participants completed a dimensional assessment of adult attachment and recognition accuracy tasks for positive and negative facial emotion expressions. Consistently, avoidant participants who were in romantic relationships, in comparison to singles, had lower decoding accuracy for facial expressions of positive emotions. The results were in line with the hypothesis that being in relationship functions as a naturalistic prime of avoidant persons' defensive tendency to ignore affiliative signals, facial expressions of positive emotion in this instance. The results inform emerging research on attachment and emotion perception by highlighting the role of perceivers' motivated social cognitions.     

The differential contribution of facial expressions,prosody, and speech content to empathy

Background: Facial expressions, prosody, and speech content constitute channels by which information is exchanged. Little is known about the simultaneous and differential contribution of these channels to empathy when they provide emotionality or neutrality. Especially neutralised speech content has gained little attention with regards to influencing the perception of other emotional cues. Methods: Participants were presented with video clips of actors telling short-stories. One condition conveyed emotionality in all channels while the other conditions either provided neutral speech content, facial expression, or prosody, respectively. Participants judged the emotion and intensity presented, as well as their own emotional state and intensity. Skin conductance served as a physiological measure of emotional reactivity. Results: Neutralising channels significantly reduced empathic responses. Electrodermal recordings confirmed these findings. The differential effect of the communication channels on empathy prerequisites was that target emotion recognition of the other decreased mostly when the face was neutral, whereas decreased emotional responses attributed to the target emotion were especially present in neutral speech. Conclusion: Multichannel integration supports conscious and autonomous measures of empathy and emotional reactivity. Emotional facial expressions influence emotion recognition, whereas speech content is important for responding with an adequate own emotional state, possibly reflecting contextual emotion-appraisal.     

Seeing what you ought to see: The role of contextual factors in the social perception of achievement emotions

To assess the impact of context information on emotion perception, participants saw a picture of a male or female person with either a neutral, happy or sad facial expression and received information about the context in which the picture was taken. Their task was to rate the emotion actually expressed in the photo (i.e., focal emotions) as well as emotions not actually expressed (i.e., non-focal emotions) and inferences extracted from them. We predicted and found that context information affected both the perception of emotions and the inferences that the observers drew from them. Perceivers used context information in order to make sense of what was perceived to the extent that in the case of neutral expressions and for non-focal emotions, they “see” things that do not actually exist.     

When did her smile drop? Facial mimicry and the influences of emotional state on the detection of change in emotional expression

Participants in manipulated emotional states played computerised movies in which facial expressions of emotion changed into categorically different expressions. The participants' task was to detect the offset of the initial expression. An effect of emotional state was observed such that individuals in happy states saw the offset of happiness (changing into sadness) at an earlier point in the movies than did those in sad states. Similarly, sad condition participants detected the offset of a sad expression changing into a happy expression earlier than did happy condition participants. This result is consistent with a proposed role of facial mimicry in the perception of change in emotional expression. The results of a second experiment provide additional evidence for the mimicry account. The Discussion focuses on the relationship between motor behaviour and perception.     

Visual-Field Bias in the Judgment of Facial Expression of Emotion

The left and right hemispheres of the brain are differentially related to the processing of emotions. Although there is little doubt that the right hemisphere is relatively superior for processing negative emotions, controversy exists over the hemispheric role in the processing of positive emotions. Eighty right-handed normal male participants were examined for visual-field (left-right) differences in the perception of facial expressions of emotion. Facial composite (RR, LL) and hemifacial (R, L) sets depicting emotion expressions of happiness and sadness were prepared. Pairs of such photographs were presented bilaterally for 150 ms, and participants were asked to select the photographs that looked more expressive. A left visual-field superiority (a right-hemisphere function) was found for sad facial emotion. A hemispheric advantage in the perception of happy expression was not found.

Individuals with Autism can Categorize Facial Expressions

The ability of high-functioning individuals with autism to perceive facial expressions categorically was studied using eight facial expression continua created via morphing software. Participants completed a delayed matching task and an identification task. Like undergraduate male participants (N = 12), performance on the identification task for participants with autism (N = 15) was predicted by performance on the delayed matching task for the angry-afraid, happy-sad, and happy-surprised continua. This result indicates a clear category boundary and suggests that individuals with autism do perceive at least some facial expressions categorically. As this result is inconsistent with findings from other studies of categorical perception in individuals with autism, possible explanations for these findings are discussed.     

Heightened sensitivity to emotional expressions in generalised anxiety disorder,compared to social anxiety disorder,and controls

Few studies have examined potential differences between social anxiety disorder (SAD) and generalised anxiety disorder (GAD) in the sensitivity to detect emotional expressions. The present study aims to compare the detection of emotional expressions in SAD and GAD. Participants with a primary diagnosis of GAD (n?=?46), SAD (n?=?70), and controls (n?=?118) completed a morph movies task. The task presented faces expressing increasing degrees of emotional intensity, slowly changing from a neutral to a full-intensity happy, sad, or angry expressions. Participants used a slide bar to view the movie frames from left to right, and to stop at the first frame where they perceived an emotion. The frame selected thus indicated the intensity of emotion required to identify the facial expression. Participants with GAD detected the onset of facial emotions at lower intensity of emotion than participants with SAD (p?=?0.002) and controls (p?=?0.039). In a multiple regression analysis controlling for age, race, and depressive symptom severity, lower frame at which the emotion was detected was independently associated and GAD diagnosis (B?=?–5.73, SE?=?1.74, p?相似文献   

威胁相关面孔表情对眼睛注视方向知觉的影响

以往研究发现眼睛注视方向知觉受面孔表情的影响,愤怒面孔相较于恐惧面孔更倾向被判断为看着观察者。虽然研究者对此提出了不同的解释,但目前尚不清楚愤怒和恐惧表情在注视方向知觉中的这种差异影响到底来自于面孔的结构信息还是物理特征信息。本研究采用注视方向辨别任务,计算直视知觉范围（The Cone of Direct Gaze,CoDG）为因变量,分别以直立,倒置及模糊图片为实验材料,试图通过分离面孔结构信息和物理特征信息,对以上问题进行探讨。结果发现在保留面孔全部信息的情况下（实验1）愤怒面孔的CoDG大于恐惧面孔;在破坏结构信息加工,只保留特征信息加工的情况下（实验2））愤怒和恐惧表情在直视知觉范围上的差异消失了;在削弱物理特征信息加工,保留结构信息加工的情况下（实验3）二者在CoDG上的差异又复现。本研究结果说明不同威胁性面孔表情对眼睛注视知觉的影响主要来自于二者在与情绪意义相关的结构信息加工上的不同,而二者非低级的物理信息上的差异,支持信号共享假说和情绪评价假说对威胁性面孔表情与注视方向整合加工解释的理论基础。     

Behavioural responses to facial and postural expressions of emotion: An interpersonal circumplex approach

While the recognition of emotional expressions has been extensively studied, the behavioural response to these expressions has not. In the interpersonal circumplex, behaviour is defined in terms of communion and agency. In this study, we examined behavioural responses to both facial and postural expressions of emotion. We presented 101 Romanian students with facial and postural stimuli involving individuals (‘targets’) expressing happiness, sadness, anger, or fear. Using an interpersonal grid, participants simultaneously indicated how communal (i.e., quarrelsome or agreeable) and agentic (i.e., dominant or submissive) they would be towards people displaying these expressions. Participants were agreeable‐dominant towards targets showing happy facial expressions and primarily quarrelsome towards targets with angry or fearful facial expressions. Responses to targets showing sad facial expressions were neutral on both dimensions of interpersonal behaviour. Postural versus facial expressions of happiness and anger elicited similar behavioural responses. Participants responded in a quarrelsome‐submissive way to fearful postural expressions and in an agreeable way to sad postural expressions. Behavioural responses to the various facial expressions were largely comparable to those previously observed in Dutch students. Observed differences may be explained from participants’ cultural background. Responses to the postural expressions largely matched responses to the facial expressions.     

Beyond the double-jeopardy hypothesis: Assessing emotion on the faces of multiply-categorizable targets of prejudice

Prior research has shown that race influences perceptions of facial expressions, with hostility detected earlier on young male Black than White faces. This study examined whether the interplay of race and age would moderate perceptions of hostility by having participants evaluate facial expressions of multiply-categorizable targets. Using a facial emotion change-detection task, we assessed evaluations of onset/offset of anger and happiness on faces of young and old Black and White men. Significant age by race interactions were observed: while participants perceived anger as lasting longer and appearing sooner on old compared to young White faces, this relationship was reversed for Black faces, with participants perceiving anger lasting longer and appearing sooner on young compared to old Black faces. Similar results were found for perceived happiness. These results suggest that perception during cross-categorization may be more complex than the simple additive function proposed by the double-jeopardy hypothesis, such that co-activation of other stereotypes may sometimes confer a protective benefit against bias.     

Age differences in vocal emotion perception: on the role of speaker age and listener sex

Older adults have greater difficulty than younger adults perceiving vocal emotions. To better characterise this effect, we explored its relation to age differences in sensory, cognitive and emotional functioning. Additionally, we examined the role of speaker age and listener sex. Participants (N?=?163) aged 19–34 years and 60–85 years categorised neutral sentences spoken by ten younger and ten older speakers with a happy, neutral, sad, or angry voice. Acoustic analyses indicated that expressions from younger and older speakers denoted the intended emotion with similar accuracy. As expected, younger participants outperformed older participants and this effect was statistically mediated by an age-related decline in both optimism and working-memory. Additionally, age differences in emotion perception were larger for younger as compared to older speakers and a better perception of younger as compared to older speakers was greater in younger as compared to older participants. Last, a female perception benefit was less pervasive in the older than the younger group. Together, these findings suggest that the role of age for emotion perception is multi-faceted. It is linked to emotional and cognitive change, to processing biases that benefit young and own-age expressions, and to the different aptitudes of women and men.     

Acute exercise suppresses judgments of facial emotion intensity

The ability to recognize others’ facial expressions is critical to the social communication of affective states. The present work examined how transient states of high physiological arousal during aerobic exercise influence recognizing and rating morphed facial expressions. Participants exercised at either a low or high work rate. While exercising and then during cool-down and rest periods, participants performed a version of the morphed faces task that involved animated faces changing into or away from five target affective states (happy, surprise, sadness, anger, and disgust); they were asked to stop the animation when the face first corresponded to a target state, and rate its emotional intensity. Results demonstrated no differences in animation stop data, but overall lower ratings of perceived emotion intensity during high versus low work rate exercise; these effects dissipated through cool-down and rest periods. Results highlight important interactions between physiological states and processing emotional information.     

Angry faces are more resistant to forgetting than are happy faces: directed forgetting effects on the identity of emotional faces

Using the item-method directed forgetting paradigm (i.e. intentionally forgetting specified information), we examined directed forgetting of facial identity as a function of facial expression and the sex of the expresser and perceiver. Participants were presented with happy and angry male and female faces cued for either forgetting or remembering, and were then asked to recognise previously studied faces from among a series of neutral faces. For each recognised test face, participants also recalled the face’s previously displayed emotional expression. We found that angry faces were more resistant to forgetting than were happy faces. Furthermore, angry expressions on male faces and happy expressions on female faces were recognised and recalled better than vice versa. Signal detection analyses revealed that male faces gave rise to a greater sensitivity than female faces did, and male participants, but not female participants, showed greater sensitivity to male faces than to female faces. Several theoretical implications are discussed.
