Who do you trust? The impact of facial emotion and behaviour on decision making

During social interactions, we use available information to guide our decisions, including behaviour and emotional displays. In some situations, behaviour and emotional displays may be incongruent, complicating decision making. This study had two main aims: first, to investigate the independent contributions of behaviour and facial displays of emotion on decisions to trust, and, second, to examine what happens when the information being signalled by a facial display is incongruent with behaviour. Participants played a modified version of the Trust Game in which they learned simulated players’ behaviour with or without concurrent displays of facial emotion. Results indicated that displays of anger, but not happiness, influenced decisions to trust during initial encounters. Over the course of repeated interactions, however, emotional displays consistent with an established pattern of behaviour made independent contributions to decision making, strengthening decisions to trust. When facial display and behaviour were incongruent, participants used current behaviour to inform decision making.     

Reducing emotional reasoning: An experimental manipulation in individuals with fear of spiders

We investigated the effects of smiling on perceptions of positive, neutral and negative verbal statements. Participants viewed computer-generated movies of female characters who made angry, disgusted, happy or neutral statements and then showed either one of two temporal forms of smile (slow vs. fast onset) or a neutral expression. Smiles significantly increased the perceived positivity of the message by making negative statements appear less negative and neutral statements appear more positive. However, these smiles led the character to be seen as less genuine than when she showed a neutral expression. Disgust + smile messages led to higher judged happiness than did anger + smile messages, suggesting that smiles were seen as reflecting humour when combined with disgust statements, but as masking negative affect when combined with anger statements. These findings provide insights into the ways that smiles moderate the impact of verbal statements.     

On Creating a Theory of Feminist Therapy

Feminism implies, and comes out of, a phenomenological philosophy. This means that we know what is true not by the "givens" of society, but by listening to our inner experience and that of others. The fundamental political act is the same as the fundamental therapeutic act: it is the process of joining another person's experience in a way which enables that person to make explicit her internal knowledge of what is real. The therapeutic stance, which implies a belief in the basic rightness of a person's way of being in the world, is what makes this kind of experimental knowing possible. To carry our thinking and practice of feminist theory forward in an authentic way, we must approach ourselves and one another from a therapeutic stance. From this we can begin to formulate a reality which encompasses the experience of those who have thus far been invisible and silenced. This article uses the problem of boundary violations as an example of a current issue in feminist therapy that can be explored from an experiential perspective. The questions that come out of this perspective can inform our creation of a therapy and society that is truly pluralistic.     

When the face fits: Recognition of celebrities from matching and mismatching faces and voices

The results of two experiments are presented in which participants engaged in a face-recognition or a voice-recognition task. The stimuli were face–voice pairs in which the face and voice were co-presented and were either “matched” (same person), “related” (two highly associated people), or “mismatched” (two unrelated people). Analysis in both experiments confirmed that accuracy and confidence in face recognition was consistently high regardless of the identity of the accompanying voice. However accuracy of voice recognition was increasingly affected as the relationship between voice and accompanying face declined. Moreover, when considering self-reported confidence in voice recognition, confidence remained high for correct responses despite the proportion of these responses declining across conditions. These results converged with existing evidence indicating the vulnerability of voice recognition as a relatively weak signaller of identity, and results are discussed in the context of a person-recognition framework.     

Culture and facial expressions of emotion

With over a century of theoretical developments and empirical investigation in broad fields (e.g., anthropology, psychology, evolutionary biology), the universality of facial expressions of emotion remains a central debate in psychology. How near or far, then, is this debate from being resolved? Here, I will address this question by highlighting and synthesizing the significant advances in the field that have elevated knowledge of facial expression recognition across cultures. Specifically, I will discuss the impact of early major theoretical and empirical contributions in parallel fields and their later integration in modern research. With illustrative examples, I will show that the debate on the universality of facial expressions has arrived at a new juncture and faces a new generation of exciting questions.     

Rapid reactions to direct and averted facial expressions of fear and anger

Recent studies have shown that reaction times to expressions of anger with averted gaze and fear with direct gaze appear slower than those to direct anger and averted fear. Such findings have been explained by appealing to the notion of gaze/expression congruence with aversion (avoidance) associated with fear, whereas directness (approach) is associated with anger. The current study examined reactions to briefly presented direct and averted faces displaying expressions of fear and anger. Participants were shown four blocked series of faces; each block contained an equal mix of two facial expressions (neutral plus either fear or anger) presented at one viewpoint (either full face or three quarter leftward facing). Participants were instructed to make rapid responses classifying the expressions as either neutral or expressive. Initial analysis of reaction time distributions showed differences in distribution shape with reactions to averted anger and direct fear showing greater skew than those to direct anger and averted fear. Computational modelling, using a diffusion model of decision making and reaction time, showed a difference in the rate of information accrual with more rapid rates of accrual when viewpoint and expression were congruent. This analysis supports the notion of signal congruence as a mechanism through which gaze and viewpoint affect our responses to facial expressions.     

Interpreting President Barack Obama's Facial Displays of Emotion: Revisiting the Dartmouth Group

Charismatic presidents like John F. Kennedy, Ronald Reagan, and now Barack Obama have been able to overcome stereotype‐based barriers to political power by connecting emotionally with viewers, particularly through their nonverbal skills. In this study we focus on the facial displays of emotion by President Obama and how participants interpret them. This study builds upon the pioneering research of the Dartmouth Group concerning response to displays of happiness‐reassurance by political leaders. It will first replicate and extend upon existing research by using Ekman and Friesen's Facial Action Coding System (FACS) to characterize facial displays by President Obama, specifically three neutral displays and three different types of smiles. Second, this study replicates research carried out over two decades ago concerning individual differences in sex, ethnicity, and age cohort on response to political candidates culturally defined as Black. Video focusing on the head and torso were FACS coded and presented in a web‐based experiment to 79 participants working at a southern institution of higher education. The participants identified the emotions felt by President Obama on a scale ranging from “not at all” to “extremely” focusing on the basic emotion terms of: “Happy” and “Playful” (happiness‐reassurance) and “Angry” and “Disgusted” (anger‐threat). Findings suggest participants differentiate between subtle facial‐display differences and that there are differences based upon ethnicity and support for President Obama when they interpret his facial displays of emotion.     

Self‐report measures,facial feedback,and personality differences (BEES) in cooperative vs. noncooperative situations: Contribution of the mimic system to the sense of empathy

The present study integrated three different measures of emotional empathic behavior in a social context: verbal self‐report measures (empathic response, emotional involvement, emotional significance, and valence), facial mimicry (activity of corrugator and zygomaticus muscles), and personal response to the Balanced Emotional Empathy Scale (BEES). Participants were presented with different interpersonal scene types (cooperation, noncooperation, conflict, indifference). Firstly, self‐rating on empathy, emotional involvement, and valence varied as a function of interpersonal context. Secondly, corrugator activity increased in response to conflictual and noncooperative situations; zygomatic activity increased in response to cooperative situations. Third, high‐ and low‐BEES subjects showed different empathic behavior: High‐empathic subjects were more responsive to empathy‐related situations than low‐empathic subjects. The convergence and divergence of these multidimensional measures was discussed.     

Emotional expressions during early infant – father conversations

The present longitudinal and naturalistic study aimed to investigate fathers' and infants' facial expressions of emotions during paternal infant-directed speech. The microanalysis of infant and paternal facial expressions of emotion in the course of the naturalistic interactions of 11 infant – father dyads, from the 2nd to the 6th month, provided evidence that: (a) fathers and infants match their emotional states and attune their emotional intensity; (b) infants seem to match paternal facial emotional expressions more than vice versa; (c) the prevailing emotional states of each partner remain constant in the beginning and at the end of speech; and (d) the developmental trajectories of infant interest and paternal pleasure change significantly across the age range of 2 – 6 months and they seem to follow similar courses. These results are interpreted within the frame of the theory of innate intersubjectivity.     

The interaction between gaze direction and facial expressions in newborns

The ability to decode facial expressions is an important component of social interaction and functioning. This ability is even more fundamental early in life, prior to the development of verbal communication. However, it is still unclear whether newborns can detect, discriminate and process facial expressions, and, if so, what the mechanisms underlying this ability are. In this study, we extend the investigation of perceived emotional expression by manipulating gaze direction with different facial expressions. Specifically, newborns were presented with faces displaying neutral, fearful, or happy facial expressions accompanied with direct or averted gaze, and tested in a visual preference paradigm. Four experiments were conducted in which different combinations of expression and gaze were used. However, only in the fourth experiment did newborns show a visual preference for a specific emotional display; they looked significantly longer at a happy face than a neutral one only when both were accompanied with direct gaze. These results provide support for the advantage of happy facial expressions in the development of a face processing system and suggest that this preference reflects experience acquired during the first few days after birth.
