Accurate identification of fear facial expressions predicts prosocial behavior

The fear facial expression is a distress cue that is associated with the provision of help and prosocial behavior. Prior psychiatric studies have found deficits in the recognition of this expression by individuals with antisocial tendencies. However, no prior study has shown accuracy for recognition of fear to predict actual prosocial or antisocial behavior in an experimental setting. In 3 studies, the authors tested the prediction that individuals who recognize fear more accurately will behave more prosocially. In Study 1, participants who identified fear more accurately also donated more money and time to a victim in a classic altruism paradigm. In Studies 2 and 3, participants' ability to identify the fear expression predicted prosocial behavior in a novel task designed to control for confounding variables. In Study 3, accuracy for recognizing fear proved a better predictor of prosocial behavior than gender, mood, or scores on an empathy scale.     

Relation of sympathy and personal distress to prosocial behavior: a multimethod study

Assessed sympathy and personal distress with facial and physiological indexes (heart rate) as well as self-report indexes and examined the relations of these various indexes to prosocial behavior for children and adults in an easy escape condition. Heart rate deceleration during exposure to the needy others was associated with increased willingness to help. In addition, adults' reports of sympathy, as well as facial sadness and concerned attention, were positively related to their intention to assist. For children, there was some indication that report of positive affect and facial distress were negatively related to prosocial intentions and behavior, whereas facial concern was positively related to the indexes of prosocial behavior. These findings are interpreted as providing additional, convergent support for the notion that sympathy and personal distress are differentially related to prosocial behavior.     

The influence of emotion type,social value orientation and processing focus on approach-avoidance tendencies to negative dynamic facial expressions

Facial expressions of anger and fear have been seen to elicit avoidance behavior in the perceiver due to their negative valence. However, recent research uncovered discrepancies regarding these immediate motivational implications of fear and anger, suggesting that not all negative emotions trigger avoidance to a comparable extent. To clarify those discrepancies, we considered recent theoretical and methodological advances, and investigated the role of social preferences and processing focus on approach-avoidance tendencies (AAT) to negative facial expressions. We exposed participants to dynamic facial expressions of anger, disgust, fear, or sadness, while they processed either the emotional expression or the gender of the faces. AATs were assessed by reaction times of lever movements, and by posture changes via head-tracking. We found that—relative to angry faces-, fearful and sad faces triggered more approach, with a larger difference between fear and anger in prosocial compared to individualistic participants. Interestingly, these findings are in line with a recently developed concern hypothesis, suggesting that—relative to other negative expressions—expressions of distress may facilitate approach, especially in participants with prosocial preferences.     

Effects of direct and averted gaze on the perception of facially communicated emotion

Research has largely neglected the effects of gaze direction cues on the perception of facial expressions of emotion. It was hypothesized that when gaze direction matches the underlying behavioral intent (approach-avoidance) communicated by an emotional expression, the perception of that emotion would be enhanced (i.e., shared signal hypothesis). Specifically, the authors expected that (a) direct gaze would enhance the perception of approach-oriented emotions (anger and joy) and (b) averted eye gaze would enhance the perception of avoidance-oriented emotions (fear and sadness). Three studies supported this hypothesis. Study 1 examined emotional trait attributions made to neutral faces. Study 2 examined ratings of ambiguous facial blends of anger and fear. Study 3 examined the influence of gaze on the perception of highly prototypical expressions.     

Adult attachment and the perception of emotional expressions: probing the hyperactivating strategies underlying anxious attachment

According to adult attachment theory, individual differences in attachment-related anxiety reflect variation in individuals' vigilance to cues relevant to appraising and monitoring the availability and responsiveness of significant others. To investigate this assumption, the authors adopted a morph movie paradigm in which participants were shown movies of faces in which an emotional facial expression changed gradually to a neutral one (Study 1) or a neutral expression changed to an emotional one (Studies 2-4). Participants were asked to judge the point at which the emotional expression had disappeared or emerged, respectively. Individuals who were highly anxious with respect to attachment were more likely to perceive the offset (Study 1) as well as the onset (Studies 2 and 3) of the facial expressions of emotion earlier than other people. Moreover, this heightened state of vigilance may have led to poorer accuracy in judging facial expressions of emotion (Study 3), an effect that was reversed when anxious individuals were required to watch the movies for the same length of time as less anxious participants (Study 4). The results indicate that variation in attachment anxiety reflects, in part, differences in vigilance to cues of social and emotional significance.     

Gender moderates the relationship between emotion and perceived gaze

Recent evidence shows that gender modulates the morphology of facial expressions and might thus alter the meaning of those expressions. Consequently, we hypothesized that gender would moderate the relationship between facial expressions and the perception of direct gaze. In Study 1, participants viewed male and female faces exhibiting joy, anger, fear, and neutral expressions displayed with direct and averted gazes. Perceptions of direct gaze were most likely for male faces expressing anger or joy and for female faces expressing joy. Study 2 established that these results were due to facial morphology and not to gender stereotypes. Thus, the morphology of male and female faces amplifies or constrains emotional signals and accordingly alters gaze perception.     

Mothers' facial expressions of pain and fear and infants' pain response during immunization

The goal of the current study was to examine the relationship between mothers' spontaneous facial expressions of pain and fear immediately preceding their infants' immunizations and infants' facial expressions of pain immediately following immunizations. Infants' observations of mothers' faces prior to immunization also were examined to explore whether these observations moderated the effect of mothers' facial expressions on infant pain. The final sample included 58 mothers and their infants. Video data were used to code maternal facial expressions, infants' observations, and infants' expressions of pain. Infants who observed their mothers' faces had mothers who expressed significantly more fear pre‐needle. Furthermore, mothers' facial expressions of mild fear pre‐needle were associated with lower levels of infants' pain expression post‐needle. A regression analysis confirmed maternal facial expressions of mild fear pre‐needle as the strongest predictor of infant pain post‐needle after controlling for infants' observations of mothers' faces. Mothers' subtle facial expressions of fear may indicate a relationship history of empathic caregiving that functions to support infants' abilities to regulate distress following painful procedures. Interventions aimed at improving caregiver sensitivity to infants' emotional cues may prove beneficial to infants in pain. Future directions in research are discussed.     

Adult attachment and the perception of facial expression of emotion

Adult attachment orientation has been associated with specific patterns of emotion regulation. The present research examined the effects of attachment orientation on the perceptual processing of emotional stimuli. Experimental participants played computerized movies of faces that expressed happiness, sadness, and anger. Over the course of the movies, the facial expressions became neutral. Participants reported the frame at which the initial expression no longer appeared on the face. Under conditions of no distress (Study 1), fearfully attached individuals saw the offset of both happiness and anger earlier, and preoccupied and dismissive individuals later, than the securely attached individuals. Under conditions of distress (Study 2), insecurely attached individuals perceived the offset of negative facial expressions as occurring later than did the secure individuals, and fearfully attached individuals saw the offset later than either of the other insecure groups. The mechanisms underlying the effects are considered.     

Why do fear and anger look the way they do? Form and social function in facial expressions

The origins of the appearances of anger and fear facial expressions are not well understood. The authors tested the hypothesis that such origins might lie in the expressions' resemblance to, respectively, mature and babyish faces in three studies. In Study 1, faces expressing anger and fear were judged to physically resemble mature and babyish faces. Study 2 indicated that characteristics associated specifically with babyishness are attributed to persons showing fear, whereas characteristics associated with maturity are attributed to persons showing anger. In Study 3, composite faces were used to minimize the possibility that the attributions were based on associations to the anger and fear emotions alone rather than to the physical resemblance of the expressions to static facial appearance cues. These results suggest that fear and anger expressions may serve socially adaptive purposes for those who show them, similar to the social adaptations associated with a babyish or mature facial appearance.     

Evidence for the Distinctness of Embarrassment,Shame, and Guilt: A Study of Recalled Antecedents and Facial Expressions of Emotion

Following proposals regarding the criteria for differentiating emotions, the current investigation examined whether the antecedents and facial expressions of embarrassment, shame, and guilt are distinct. In Study 1, participants wrote down events that had caused them to feel embarrassment, shame, and guilt. Coding of these events revealed that embarrassment was associated with transgressions of conventions that govern public interactions, shame with the failure to meet important personal standards, and guilt with actions that harm others or violate duties. Study 2 determined whether these three emotions are distinct in another domain of emotion-namely, facial expression. Observers were presented with slides of 14 different facial expressions, including those of embarrassment, shame, and candidates of guilt (self-contempt, sympathy, and pain). Observers accurately identified the expressions of embarrassment and shame, but did not reliably label any expression as guilt.     

Extinction of an emotional response in the presence of facial expressions of emotion

Previous studies (Lanzetta & Orr, 1980, 1981; Orr & Lanzetta, 1980) have demonstrated that fear facial expressions have the functional properties of conditioned excitatory stimuli, while happy expressions behave as conditioned inhibitors of emotional responses. The present study uses a summation conditioning procedure to distinguish between associative and nonassociative (selective sensitizations, attentional) interpretations of these findings. A neutral tone was first established as a conditioned excitatory CS by reinforcing tone presentations with shock. In subsequent nonreinforced test trials the excitatory tone was paired with either fear, happy, or neutral facial expressions. A tone alone and a tone/nonface slide compound were used as controls. The results indicate that phasic and tonic skin conductance responses to the tone/fear expression compound were significantly larger during extinction than for all other experimental and control groups. No significant differences were found among these latter conditions. The findings support the assumption that the excitatory characteristics of fear expressions do not depend on associative mechanisms. In the presence of fear cues, fear facial expressions intensify the emotional reaction and disrupt extinction of a previously acquired fear response. Happy facial expressions however, do not function as conditioned inhibitors in the absence of reinforcement, suggesting that the previously found inhibition was associative in nature.This research was supported by NSF grant No. 77-08926 and by funds from the Lincoln Filene Endowment to Dartmouth College.     

When time stands still: fear-specific modulation of temporal bias due to threat

The current study was designed to test the fear-specific nature of temporal bias due to threat. A temporal bisection procedure was used in which participants (N = 46) were initially trained to recognize short (400 ms) and long (1,600 ms) standard durations. In the test phase, participants were asked to judge whether the duration of computer-generated faces drawn to appear threatening, fearful, and neutral, was closer to either the short or long duration they had learnt earlier. Past research was replicated-the durations of the arousing facial expressions were overestimated relative to a low arousal (neutral) expression. Overestimation for threat was positively correlated with individual differences in fearfulness, trait anxiety, and distress. Multiple regression analyses were carried out to test the hypothesis was that individual differences in anxiety and fearfulness but not other traits would uniquely predict temporal overestimation due to threat. The results showed that fearfulness but not other traits (trait anxiety, anger, distress, activity, and sociability) was a unique and strong (partial r = .47) predictor of increased overestimation for both threatening and fearful expressions. The findings support the hypothesis that threat-related expressions activate a fear-specific system (?hman & Mineka, 2001) or fear representations (Beck & Clark, 1997) in fearful individuals.     

The effect of inducing panic search on the detection of fear-relevant and neutral images

Panic search occurs when the presentation of a fearful facial expression precue, prior to a search display, improves target detection relative to when neutral and positive expressions are used. In the present study, fearful and neutral expressions acted as precues and targets were images of either neutral or threatening animals. It was predicted that detection of a threatening image following a fearful precue would be particularly facilitated. In a first experiment, target detection was better when targets were threatening than neutral, but the predicted cue enhancement did not occur. In a second experiment, when cue type was blocked, participants were particularly facilitated in responding to threatening targets following fearful precues. It is concluded that consistent and repeated exposure to threatening facial expression results in a generalized increase in processing efficiency and that such a state induces a particular facilitation in responding in the presence of threatening targets.     

Empathy: Conceptualization,measurement, and relation to prosocial behavior

Empathy, sympathy, and related vicarious emotional responses are important concepts in developmental, social, and clinical psychology. The purpose of this paper is to examine conceptual and methodological issues concerning the assessment of vicarious emotional responding and to present data from a series of multimethod studies on the assessment of empathy-related reactions and their association with prosocial behavior. The findings presented are consistent with several conclusions: (a) In some contexts, physiological, facial, and self-report indexes can be useful markers of vicarious emotional responses, (b) other-oriented sympathetic responding is positively related to prosocial behavior (particularly altruism) whereas personal distress reactions sometimes are associated with low levels of helping, and (c) physiological arousal is higher for personal distress than sympathetic reactions.This research was supported by a grant from the National Science Foundation (BNS8807784) to the first two authors and a Career Development Award from the National Institute of Child Health and Development (K04 HD00717) to Nancy Eisenberg. A version of this paper was presented at the American Association for the Advancement of Science in New Orleans, February 1990.     

A robust method for measuring an individual’s sensitivity to facial expressions

This paper describes a method to measure the sensitivity of an individual to different facial expressions. It shows that individual participants are more sensitive to happy than to fearful expressions and that the differences are statistically significant using the model-comparison approach. Sensitivity is measured by asking participants to discriminate between an emotional facial expression and a neutral expression of the same face. The expression was diluted to different degrees by combining it in different proportions with the neutral expression using morphing software. Sensitivity is defined as measurement of the proportion of neutral expression in a stimulus required for participants to discriminate the emotional expression on 75% of presentations. Individuals could reliably discriminate happy expressions diluted with a greater proportion of the neutral expression compared with that required for discrimination of fearful expressions. This tells us that individual participants are more sensitive to happy compared with fearful expressions. Sensitivity is equivalent when measured on two different testing sessions, and greater sensitivity to happy expressions is maintained with short stimulus durations and stimuli generated using different morphing software. Increased sensitivity to happy compared with fear expressions was affected at smaller image sizes for some participants. Application of the approach for use with clinical populations, as well as understanding the relative contribution of perceptual processing and affective processing in facial expression recognition, is discussed.

     

Caricaturing facial expressions

The physical differences between facial expressions (e.g. fear) and a reference norm (e.g. a neutral expression) were altered to produce photographic-quality caricatures. In Experiment 1, participants rated caricatures of fear, happiness and sadness for their intensity of these three emotions; a second group of participants rated how 'face-like' the caricatures appeared. With increasing levels of exaggeration the caricatures were rated as more emotionally intense, but less 'face-like'. Experiment 2 demonstrated a similar relationship between emotional intensity and level of caricature for six different facial expressions. Experiments 3 and 4 compared intensity ratings of facial expression caricatures prepared relative to a selection of reference norms - a neutral expression, an average expression, or a different facial expression (e.g. anger caricatured relative to fear). Each norm produced a linear relationship between caricature and rated intensity of emotion; this finding is inconsistent with two-dimensional models of the perceptual representation of facial expression. An exemplar-based multidimensional model is proposed as an alternative account.     

Facial emotion recognition during pregnancy: Examining the effects of facial age and affect

It is vital that new mothers quickly and accurately recognize their child’s facial expressions. There is evidence that during pregnancy women develop enhanced processing of facial features associated with infancy and distress, as these cues signal vulnerability and are therefore biologically salient. In this study, 51 pregnant women at 17–36 weeks gestation watched neutral infant and adult faces gradually morph into either happy or sad expressions. We measured the speed and accuracy with which participants were able to recognize facial affect (happy vs. sad) across facial ages (infant vs. adult). Participants were faster and more accurate at recognizing happy versus sad faces and adult versus infant faces. We discuss how prior exposure to a certain face type may explain faster recognition. We also consider these results in the context of evidence indicating positive affect is recognized more quickly, but associated with slower attention and detection.     

Well, slap my thigh: expression of surprise facilitates memory of surprising material

Two studies examined the general prediction that one's emotional expression should facilitate memory for material that matches the expression. The authors focused on specific facial expressions of surprise. In the first study, participants who were mimicking a surprised expression showed better recall for the surprising words and worse recall for neutral words, relative to those who were mimicking a neutral expression. Study 2 replicated the results of Study 1, showing that participants who mimicked a surprised expression recalled more words spoken in a surprising manner compared with those that sounded neutral or sad. Conversely, participants who mimicked sad facial expressions showed greater recall for sad than neutral or surprising words. The results provide evidence of the importance of matching the emotional valence of the recall content to the facial expression of the recaller during the memorization period.

Why mood affects help giving,but not moral courage: Comparing two types of prosocial behaviour

A long tradition in the help giving literature assumes that mood states determine the level of prosocial behaviour shown by individuals. Most research in this area has been conducted in the context of low cost prosocial behaviour, whereas research has been neglected in which participants were confronted with situations involving potential severe and dangerous negative consequences (i.e., high cost situations) with the help‐giver risking his moral integrity and social disapproval (i.e., moral courage). To address this gap in the literature, the present studies investigate differential effects of positive and negative compared with neutral mood states on help giving versus moral courage. Study 1 shows that in situations requiring low cost helping, participants were more likely to help in positive and negative moods than those in a neutral mood, whereas in situations requiring moral courage (high cost), participants were comparably likely to help in each of the three mood conditions. In Study 2, we find that salience of moral norms mediates the interaction between type of prosocial behaviour and mood. Finally, Study 3 investigates whether the apparent discrepancy between help giving and moral courage as established by the differential impact of mood states can be determined still differently. It reveals that justice sensibility, civil disobedience, resistance to group pressure, moral mandates, and anger lead to moral courage, but not to help giving. Differences between these two types of prosocial behaviour are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

A functional MRI study of human amygdala responses to facial expressions of fear versus anger

Functional magnetic resonance imaging (fMRI) of the human brain was used to compare changes in amygdala activity associated with viewing facial expressions of fear and anger. Pictures of human faces bearing expressions of fear or anger, as well as faces with neutral expressions, were presented to 8 healthy participants. The blood oxygen-level dependent (BOLD) fMRI signal within the dorsal amygdala was significantly greater to Fear versus Anger, in a direct contrast. Significant BOLD signal changes in the ventral amygdala were observed in contrasts of Fear versus Neutral expressions and, in a more spatially circumscribed region, to Anger versus Neutral expressions. Thus, activity in the amygdala is greater to fearful facial expressions when contrasted with either neutral or angry faces. Furthermore, directly contrasting fear with angry faces highlighted involvement of the dorsal amygdaloid region.
