The effect of expression sequence and expressor identity on judgments of the intensity of facial expression

Subjects were exposed to a sequence of facial expression photographs to determine whether viewing earlier expressions in a sequence would alter intensity judgments of a final expression in the sequence. Results showed that whether the preceding expressions were shown by the same person who displayed the final expression, or different people, intensity ratings of both sad and happy final expressions were enhanced when preceded by a sequence of contrasting as opposed to similar or identical facial expressions. Results are discussed from the perspective of adaptation-level theory.     

The Relationship Between Processing Facial Identity and Emotional Expression in 8‐Month‐Old Infants

In Experiment 1, it was investigated whether infants process facial identity and emotional expression independently or in conjunction with one another. Eight‐month‐old infants were habituated to two upright or two inverted faces varying in facial identity and emotional expression. Infants were tested with a habituation face, a switch face, and a novel face. In the switch faces, a new combination of identity and emotional expression was presented. The results show that infants differentiated between switch and habituation faces only in the upright condition but not in the inverted condition. Experiment 2 provides evidence that infants’ nonresponse in the inverted condition can be attributed to their independent processing of facial identity and emotional expression. This suggests that infants in the upright condition processed facial identity and emotional expression in conjunction with one another.     

Moderating Effects of Facial Expression and Movement on the Babyface Stereotype

We investigated whether the well-documented babyface stereotype is moderated by facial movement or expression. Impressions of more babyfaced women as warmer and less dominant were weaker when faces were moving than when they were static. These moderating effects of facial movement were consistent with its tendency to reduce the perceived anger of low babyfaced women. Impressions of more babyfaced women as less dominant were equally strong whether faces showed a neutral or surprised expression, but impressions of them as warmer were significant only for neutral expressions. The moderating effect of facial expression on impressions of warmth was consistent with the tendency for surprise expressions to attenuate differences in the perceived babyfaceness of high and low babyfaced people. Theoretical interpretations and practical implications are discussed.     

Do Socially Anxious Children Show Deficits in Classifying Facial Expressions of Emotions?

Studies with socially anxious adults suggest that social anxiety is associated with problems in decoding other persons' facial expressions of emotions. Corresponding studies with socially anxious children are lacking. The aim of the present study was to test whether socially phobic children show deficits in classifying facial expressions of emotions or show a response bias for negative facial expressions. Fifty socially anxious and 25 socially non-anxious children (age 8 to 12) participated in the study. Pictures of faces with either neutral, positive (joyful) or negative (angry, disgusted, sad) facial expressions (24 per category) were presented for 60 ms on a monitor screen in random order. The children were asked to indicate by pressing a key whether the facial expression was neutral, positive, or negative, and to rate how confident they were about their classification. With regard to frequency of errors the socially anxious children reported significantly more often that they saw emotions when neutral faces were presented. Moreover, reaction times were longer. However, they did not feel less certain about their performance. There is neither an indication of an enhanced ability to decode negative facial expressions in socially anxious children, nor was there a specific tendency to interpret neutral or positive faces as negative.     

Mother and Child Facial Expression Labeling Skill Relates to Mutual Responsiveness During Emotional Conversations

The capacity to engage with one’s child in a reciprocally responsive way is an important element of successful and rewarding parent–child conversations, which are common contexts for emotion socialization. The degree to which a parent–child dyad shows a mutually responsive orientation presumably depends on both individuals’ socio-emotional skills. For example, one or both members of a dyad needs to be able to accurately interpret and respond to the other’s nonverbal cues, such as facial expressions, to facilitate mutually responsive interactions. Little research, however, has examined whether and how mother and/or child facial expression decoding skill relates to dyads’ emotional mutuality during conversations. We thus examined associations between both mother and child facial expression decoding skill and observed emotional mutuality during parent-preschooler conversations about happy child memories. Results lend support to our hypotheses by suggesting that both mother and child capacities to read others’ emotional cues make distinct contributions to parent–child emotional mutuality in the context of reminiscing conversations. Specifically, mothers’ accurate decoding of child facial expressions predicted maternal displays of positive affect and interest, while children’s accurate decoding of adult facial expressions predicted dyadic displays of mutual enjoyment. Contrary to our hypotheses, however, parent/child facial expression decoding skills did not interact to predict observed mutual responsiveness. These findings underscore the importance of attending to both parent and child contributions to successful dyadic interactions that facilitate effective emotion socialization.     

Spontaneous Facial Expressions Reveal New Action Units for the Sad Experiences

Facial expressions related to sadness are a universal signal of nonverbal communication. Although results of many psychology studies have shown that drooping of the lip corners, raising of the chin, and oblique eyebrow movements (a combination of inner brow raising and brow lowering) express sadness, no report has described a study elucidating facial expression characteristics under well-controlled circumstances with people actually experiencing the emotion of sadness itself. Therefore, spontaneous facial expressions associated with sadness remain unclear. We conducted this study to accumulate important findings related to spontaneous facial expressions of sadness. We recorded the spontaneous facial expressions of a group of participants as they experienced sadness during an emotion-elicitation task. This task required a participant to recall neutral and sad memories while listening to music. We subsequently conducted a detailed analysis of their sad and neutral expressions using the Facial Action Coding System. The prototypical facial expressions of sadness in earlier studies were not observed when people experienced sadness as an internal state under non-social circumstances. By contrast, they expressed tension around the mouth, which might function as a form of suppression. Furthermore, results show that parts of these facial actions are not only related to sad experiences but also to other emotional experiences such as disgust, fear, anger, and happiness. This study revealed the possibility that new facial expressions contribute to the experience of sadness as an internal state.     

Lying through others: Does delegation promote deception?

How do agency relationships affect an individual’s willingness to lie for monetary advantage? Does lie aversion decline if a lie (or truth) is sent through an agent, rather than sent directly by the individual? In a recent paper, Erat (2013) shows that a significant proportion of his subjects prefer to delegate a deception decision. We present experiments designed to focus on one of several possible explanations for this intriguing behavior – that delegation reduces lie aversion. The experiments reveal that subjects are more willing to lie through a delegate than to lie directly despite controlling for potential effects of delegated decision-making on preferences over payoffs, probabilities of actions, and/or the desire to avoid taking a decision.     

How the Experience of Emotion is Modulated by Facial Feedback

The facial feedback hypothesis states that facial actions modulate subjective experiences of emotion. Using the voluntary facial action technique, in which the participants react with instruction induced smiles and frowns when exposed to positive and negative emotional pictures and then rate the pleasantness of these stimuli, four questions were addressed in the present study. The results in Experiment 1 demonstrated a feedback effect because participants experienced the stimuli as more pleasant during smiling as compared to when frowning. However, this effect was present only during the critical actions of smiling and frowning, with no remaining effects after 5 min or after 1 day. In Experiment 2, feedback effects were found only when the facial action (smile/frown) was incongruent with the presented emotion (positive/negative), demonstrating attenuating but not enhancing modulation. Finally, no difference in the intensity of produced feedback effect was found between smiling and frowning, and no difference in feedback effect was found between positive and negative emotions. In conclusion, facial feedback appears to occur mainly during actual facial actions, and primarily attenuate ongoing emotional states.     

Newborns' Face Recognition: The Role of Facial Movement

This study investigates the role of dynamic information in identity face recognition at birth. More specifically we tested whether semi‐rigid motion, conveyed by a change in facial expression, facilitates identity recognition. In Experiment 1, two‐day‐old newborns, habituated to a static happy or fearful face (static condition) have been tested using a pair of novel and familiar identity static faces with a neutral expression. Results indicated that newborns manifest a preference for the familiar stimulus, independently of the facial expression. In contrast, in Experiment 2 newborns habituated to a semi‐rigid moving face (dynamic condition) manifest a preference for the novel face, independently of the facial expression. In Experiment 3, a multistatic image of a happy face with different degrees of intensity was utilized to test the role of different amount of static pictorial information in identity recognition (multistatic image condition). Results indicated that newborns were not able to recognize the face to which they have been familiarized. Overall, results clearly demonstrate that newborns' face recognition is strictly dependent on the learning conditions and that the semi‐rigid motion conveyed by facial expressions facilitates identity recognition since birth.     

Newborn Infants' Preference for Attractive Faces: The Role of Internal and External Facial Features

Several previous experiments have found that newborn and young infants will spend more time looking at attractive faces when these are shown paired with faces judged by adults to be unattractive. Two experimental conditions are described with the aim of finding whether the “attractiveness effect” results from attention to internal or external facial features, or both. Pairs of attractive and less attractive faces (as judged by adults) were shown to newborn infants (mean age 2 days, 9 hours), where each pair had either identical internal features (and different external features) or identical external features (and different internal features). In the latter, but not the former, condition the infants looked longer at the attractive faces. These findings are clear evidence that newborn infants use information about internal facial features in making preferences based on attractiveness. It is suggested that when newborn (and older) infants are presented with facial stimuli, whether dynamic or static, they are able to attend both to internal and external facial features.     

Political restructuring,bureaucratization and minority groups in Myanmar: The case of Rohingya from 2011 to 2018

Politics of ethnicity can have serious repercussions if balance of interests is not maintained and this can lead to internal destabilization of states. This is the case in Myanmar, a situation which has brought suffering and deaths of thousands; effectively raising concerns and opprobrium against the government of Myanmar. Minority groups in Myanmar are greatly oppressed, though recent proceedings have seen the democratically elected government trying to avert the situation, while facing great restraints from the military which has been in control of the government for decades. The transformation process to uphold minority rights is marred with controversy as the Rohingya systematic alienation has persisted even in the new political dispensation. Discriminatory, cumbrous bureaucratic tendencies, are constantly used to control and manipulate the Rohingya to force them out of the country, a system which is ultimately backed by state sponsored violence. This research therefore, seeks to critically examine how the bureaucratic systems in Myanmar has been weaponized to systematically suppress rights of the Rohingya. Most research has focused on the butchering and series of violence against the Rohingya but this is generally a condensed and comprehensive analysis of the direct contribution of the bureaucrats as the implementers of public policy. This research concludes that, the doctrine of sovereignty has largely remained the salvation harboring and facilitating the continuity of repressive regimes despite the existence of the doctrine of limited sovereignty. Most importantly, the Rohingyian ordeal hints on the failures of the United Nations as actions of member states are conditioned by their selfish interests and states would only act where their national interest lie. There is need to create a global authority with executive legislative, judiciary, military and constitutional authority to exert authority over governments.     

Neonate and Infant Emotion Expression Perceived by Adults

This exploratory study investigates the meaning that adults attribute to the facial expressions of neonates and young infants using different types of scales, and tries to assess whether adult judgments get more precise as the infants get older. We videotaped longitudinally six infants' facial expressions in 5 everyday life situations at 3 days, 1 month, and 3 months old. Untrained adult decoders had to assess the activation and pleasure/displeasure levels signaled by the isolated videotaped facial expressions, recognize the stimulus situations, and attribute a verbal label to each expression. Our results showed that inter-decoder agreement was higher when the babies' facial expressions were considered as signals of activation or of pleasure/displeasure, and decreased significantly when the expressions had to be interpreted as signals of specific situations or when a verbal label had to be ascribed. The specificity and the accuracy of the answers, and inter-decoder agreement, were higher for the older infants.     

Facial Mimicry of Spontaneous and Deliberate Duchenne and Non-Duchenne Smiles

Increasing evidence suggests that Duchenne (D) smiles may not only occur as a sign of spontaneous enjoyment, but can also be deliberately posed. The aim of this paper was to investigate whether people mimic spontaneous and deliberate D and non-D smiles to a similar extent. Facial EMG responses were recorded while participants viewed short video-clips of each smile category which they had to judge with respect to valence, arousal, and genuineness. In line with previous research, valence and arousal ratings varied significantly as a function of smile type and elicitation condition. However, differences in facial reactions occurred only for smile type (i.e., D and non-D smiles). The findings have important implications for questions relating to the role of facial mimicry in expression understanding and suggest that mimicry may be essential in discriminating among various meanings of smiles.     

The Stability of Facial Attractiveness: Is It What You’ve Got or What You Do with It?

Physical attractiveness is suggested to be an indicator of biological quality and therefore should be stable. However, transient factors such as gaze direction and facial expression affect facial attractiveness, suggesting it is not. We compared the relative importance of variation between faces with variation within faces due to facial expressions. 128 participants viewed photographs of 14 men and 16 women displaying the six basic facial expressions (anger, disgust, fear, happiness, sadness, surprise) and a neutral expression. Each rater saw each model only once with a randomly chosen expression. The effect of expressions on attractiveness was similar in male and female faces, although several expressions were not significantly different from each other. Identity was 2.2 times as important as emotion in attractiveness for both male and female pictures, suggesting that attractiveness is stable. Since the hard tissues of the face are unchangeable, people may still be able to perceive facial structure whatever expression the face is displaying, and still make attractiveness judgements based on structural cues.     

Lying and nonverbal behavior: Theoretical issues and new findings

Conceptual issues about deceit, in specific why lies fail and when and how behavior may betray a lie, provides the basis for considering the type of experimental situations which may be fruitful for the study of deceit. New evidence, integrating past reports with new unpublished findings, compare the relative efficacy of facial, bodily, vocal, paralinguistic and textual measures in discriminating deceptive from honest behavior. The findings show also that most people do not rely upon the most useful sources of information in judging whether someone is lying.The information reported here also appears inCredibility Assessment—A Unified Theoretical and Research Perspective, J. Yuille (Ed.), in press, Kluwer. The work described was supported by a Research Scientist Award from the National Institute of Mental Health (MH 06092) and a previous grant from NIMH (MH11976).     

Big girls don't frown,big boys don't cry—Gender differences of professional actors in communicating emotion via facial expression

It was tested whether professional actors would be able to communicate emotional meaning via facial expression when this is presented to judges without context information. Forty takes were selected from movies, depicting a female or a male actor in close-up showing facial expression. These close-ups were selected by two expert judges, who knew the complete movie and had to agree on the emotion expressed or expected to be expressed by the female or male actor in the respective take. Five takes each were selected to represent the basic emotions of joy, sadness, fear, and anger. Twenty takes each were selected showing female and male actors. These 40 takes (edited in random order onto video tape) were presented to 90 judges (about half female and half male; about half younger pupils and about half older ones), whose task it was to judge the emotion(s) expressed on nine 5-point-emotion scales. Results indicated that female actors are somewhat better (though not statistically significant) in communicating emotion via facial expression without context than male actors are. Furthermore, significant interactions between portrayed emotion and gender of actors were found: While recognition rate for joy is very high and identical for both genders, female actors seem to be superior in communicating fear and sadness via facial expression, while male actors are more successful in communicating anger. A display rule approach seems to be appropriate for the interpretation of these results, indicating that gender-specific attempts to control/inhibit certain emotions do not only exist in real life, but also in movies.The research reported here was supported by a grant of the Deutsche Forschungsgemeinschaft (WA 519/2-2). I thank Uwe Balser and Tina Mertesacker for their help in selecting the stimuli, preparing the judgment tapes, recruiting subjects and conducting the study.     

A Smile Enhances 3‐Month‐Olds’ Recognition of an Individual Face

Recent studies demonstrated that in adults and children recognition of face identity and facial expression mutually interact ( Bate, Haslam, & Hodgson, 2009 ; Spangler, Schwarzer, Korell, & Maier‐Karius, 2010 ). Here, using a familiarization paradigm, we explored the relation between these processes in early infancy, investigating whether 3‐month‐old infants’ ability to recognize an individual face is affected by the positive (happiness) or neutral emotional expression displayed. Results indicated that infants’ face recognition appears enhanced when faces display a happy emotional expression, suggesting the presence of a mutual interaction between face identity and emotion recognition as early as 3 months of age.     

How People Really Suspect and Discover Lies

Previous research suggested that real-world lies are detected through hard evidence, such as physical evidence or a direct confession, and not via nonverbal clues. However, we argue that discovering a lie is a process, and nonverbal clues are an important source of information that can induce suspicion, which then triggers the search for hard evidence. We replicated an original study suggesting the irrelevance of nonverbal clues, but experimentally manipulated the wording of the critical question as ‘discovering’ a lie versus ‘suspecting’ a lie. A second study was conducted that further manipulated the phrasing to ask about ‘events’ versus ‘clues’ that led one to detect the lie. Results of both studies showed that those asked about suspecting a lie cited nonverbal behaviors significantly more often than those asked about discovering a lie. Thus, in contrast to previous research, these findings suggest the importance of behavioral clues (e.g. verbal and nonverbal behavior), specifically in the early stage of lie detection.
