Recognizing emotion in faces: Developmental effects of child abuse and neglect.

The contributions to the recognition of emotional signals of (a) experience and learning versus (b) internal predispositions are difficult to investigate because children are virtually always exposed to complex emotional experiences from birth. The recognition of emotion among physically abused and physically neglected preschoolers was assessed in order to examine the effects of atypical experience on emotional development. In Experiment 1, children matched a facial expression to an emotional situation. Neglected children had more difficulty discriminating emotional expressions than did control or physically abused children. Physically abused children displayed a response bias for angry facial expressions. In Experiment 2, children rated the similarity of facial expressions. Control children viewed discrete emotions as dissimilar, neglected children saw fewer distinctions between emotions, and physically abused children showed the most variance across emotions. These results suggest that to the extent that children's experience with the world varies, so too will their interpretation and understanding of emotional signals.

Children's and adults' recognition of spontaneous and posed emotional expressions in young children.

Investigated the degree to which 4–5 yr olds (n?=?48) can enact expressions of emotion recognizable by peers and adults; the study also examined whether accuracy of recognition was a function of age and whether the expression was posed or spontaneous. Adults (n?=?103) were much more accurate than children in recognizing neutral states, slightly more accurate in recognizing happiness and anger, and equally accurate in recognizing sadness. Children's spontaneous displays of happiness were more recognizable than posed displays, but for other emotions there was no difference between the recognizability of posed and spontaneous expressions. Children were highly accurate in identifying the facial expressions of happiness, sadness, and anger displayed by their peers. Sex and ethnicity of the child whose emotion was displayed interacted to influence only adults' recognizability of anger. Results are discussed in terms of the social learning and cognitive developmental factors influencing (a) adults' and children's decoding (recognition) of emotional expressions in young children and (b) encoding (posing) of emotional expressions by young children.

Maternal facial behavior and the recognition and production of emotional expression by maltreated and nonmaltreated children.

20 maltreated and 20 nonmaltreated children (ages?=?3–7 years) and their mothers were observed during a laboratory play session and 7 home observation visits. Ss' facial behavior was video recorded in the lab and coded live by observers in the home. Children also participated in an emotional-expression recognition task. Data analysis showed that both maltreatment status and mothers' facial behavior were predictors of children's recognition scores. Positive relationships were also found between mothers' and children's expressive behavior. Although maltreated and nonmaltreated children differed significantly in their recognition of emotional facial expressions, group differences were not found for either mothers' or children's expressive behavior. Overall, this study's findings indicate that children's recognition and production of facial expressions depends in part on the expressive environment provided by their mothers.

Interpersonal processes in friendship: A comparison of abused and nonabused children's experiences.

Although parental maltreatment has been presumed to have deleterious effects on children's abilities to form close relationships, observations of abused children with their best friends have rarely been conducted. Sixteen 9- to 14-year-old physically abused children and 32 matched nonabused children were observed during a 1.5-hr sequence of unstructured and structured tasks. Coding focused primarily on intimacy, conflict, and affective expression. Abused children and their friends displayed less overall intimacy than nonabused children and their friends, although peak levels of intimacy were similar for the 2 groups. Dyads containing an abused child were more conflictual than dyads without abused children, especially during game-playing activities. Abused boys and their friends also displayed more negative affect during game playing than did dyads of nonabused friends. Abused girls and their friends displayed less positive affect than other friendship dyads during activities involving primarily conversation and discussion. Several effects of gender and context not specific to abuse were also obtained. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Voluntary expressive changes and emotion.

Examined the influence of changes in facial expression on physiological and self-report measures of emotion. In Exp I, 27 undergraduates portrayed facial expressions associated with being afraid, calm, and normal. Portraying fear produced increases in pulse rate and skin conductance relative to portraying either calm or normal, but posing had no effect on subjective reports of anxiety (Affect Adjective Check List). In Exp II, 38 Ss listened to loud or soft noise while changing their expressions to portray fear, happiness, or calmness. Portraying either fear or happiness produced greater arousal than remaining calm. Changes in facial expression failed to affect self-reports of noise loudness. Results suggest that changes in facial expression influence physiological responses through the movement involved in posing and may not influence self-reports of emotion at all.

Physical abuse amplifies attention to threat and increases anxiety in children.

Two experiments using event-related potentials (ERPs) examined the extent to which early traumatic experiences affect children's ability to regulate voluntary and involuntary attention to threat. The authors presented physically abused and nonabused comparison children with conflicting auditory and visual emotion cues, posed by children's mothers or a stranger, to examine the effect of emotion, modality, and poser familiarity on attention regulation. Relative to controls, abused children overattended to task-relevant visual and auditory anger cues. They also attended more to task-irrelevant auditory anger cues. Furthermore, the degree of attention allocated to threat statistically mediated the relationship between physical abuse and child-reported anxiety. These findings indicate that extreme emotional experiences may promote vulnerability for anxiety by influencing the development of attention regulation abilities.

Class II correction with magnets and superelastic coils followed by straight-wire mechanotherapy. Occlusal changes during and after dental therapy

We investigated facial recognition memory (for previously unfamiliar faces) and facial expression perception with functional magnetic resonance imaging (fMRI). Eight healthy, right-handed volunteers participated. For the facial recognition task, subjects made a decision as to the familiarity of each of 50 faces (25 previously viewed; 25 novel). We detected signal increase in the right middle temporal gyrus and left prefrontal cortex during presentation of familiar faces, and in several brain regions, including bilateral posterior cingulate gyri, bilateral insulae and right middle occipital cortex during presentation of unfamiliar faces. Standard facial expressions of emotion were used as stimuli in two further tasks of facial expression perception. In the first task, subjects were presented with alternating happy and neutral faces; in the second task, subjects were presented with alternating sad and neutral faces. During presentation of happy facial expressions, we detected a signal increase predominantly in the left anterior cingulate gyrus, bilateral posterior cingulate gyri, medial frontal cortex and right supramarginal gyrus, brain regions previously implicated in visuospatial and emotion processing tasks. No brain regions showed increased signal intensity during presentation of sad facial expressions. These results provide evidence for a distinction between the neural correlates of facial recognition memory and perception of facial expression but, whilst highlighting the role of limbic structures in perception of happy facial expressions, do not allow the mapping of a distinct neural substrate for perception of sad facial expressions.     

Effects of early experience on children's recognition of facial displays of emotion.

The present research examines visual perception of emotion in both typical and atypical development. To examine the processes by which perceptual mechanisms become attuned to the contingencies of affective signals in the environment, the authors measured the sequential, content-based properties of feature detection in emotion recognition processes. To evaluate the role of experience, they compared typically developing children with physically abused children, who were presumed to have experienced high levels of threat and hostility. As predicted, physically abused children accurately identified facial displays of anger on the basis of less sensory input than did controls, which suggests that physically abused children have facilitated access to representations of anger. The findings are discussed in terms of experiential processes in perceptual learning. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Body expressions influence recognition of emotions in the face and voice.

The most familiar emotional signals consist of faces, voices, and whole-body expressions, but so far research on emotions expressed by the whole body is sparse. The authors investigated recognition of whole-body expressions of emotion in three experiments. In the first experiment, participants performed a body expression-matching task. Results indicate good recognition of all emotions, with fear being the hardest to recognize. In the second experiment, two alternative forced choice categorizations of the facial expression of a compound face-body stimulus were strongly influenced by the bodily expression. This effect was a function of the ambiguity of the facial expression. In the third experiment, recognition of emotional tone of voice was similarly influenced by task irrelevant emotional body expressions. Taken together, the findings illustrate the importance of emotional whole-body expressions in communication either when viewed on their own or, as is often the case in realistic circumstances, in combination with facial expressions and emotional voices.

Recognition of facial expressions of emotion by children with attention-deficit hyperactivity disorder

Fifty children and adolescents were tested for their ability to recognize the 6 basic facial expressions of emotion depicted in Ekman and Friesen's normed photographs. Subjects were presented with sets of 6 photographs of faces, each portraying a different basic emotion, and stories portraying those emotions were read to them. After each story, the subject was asked to point to the photograph in the set that depicted the emotion described. Overall, the children correctly identified the emotions on 74% of the presentations. The highest level of accuracy in recognition was for happiness, followed by sadness, with fear being the emotional expression that was mistaken most often. When compared to studies of children in the general population, children with ADHD have deficits in their ability to accurately recognize facial expressions of emotion. These findings have important implications for the remediation of social skill deficits commonly seen in children with ADHD.     

When the face reveals what words do not: Facial expressions of emotion, smiling, and the willingness to disclose childhood sexual abuse.

For survivors of childhood sexual abuse (CSA), verbal disclosure is often complex and painful. The authors examined the voluntary disclosure-nondisclosure of CSA in relation to nonverbal expressions of emotion in the face. Consistent with hypotheses derived from recent theorizing about the moral nature of emotion, CSA survivors who did not voluntarily disclose CSA showed greater facial expressions of shame, whereas CSA survivors who voluntarily disclosed CSA expressed greater disgust. Expressions of disgust also signaled sexual abuse accompanied by violence. Consistent with recent theorizing about smiling behavior, CSA nondisclosers made more polite smiles, whereas nonabused participants expressed greater genuine positive emotion. Discussion addressed the implications of these findings for the study of disclosure of traumatic events, facial expression, and the links between morality and emotion.

Intact recognition of facial emotion in Parkinson's disease.

Although the basal ganglia have been shown to be critical for the expression of emotion in prosody and facial expressions, it is unclear whether they are also critical for recognition of emotions. Selective pathology of parts of the basal ganglia is a hallmark of individuals with Parkinson's disease, and such patients have been examined in several studies of emotion. We examined 18 patients with Parkinson's disease (11 men, 7 women) and 13 age-, education-, gender ratio-, and IQ-matched normal controls on their ability to recognize emotions signaled by facial expressions. Parkinson's patients performed entirely normally on a quantitative task of recognizing emotional facial expressions. The findings do not support the notion that the sectors of basal ganglia that are dysfunctional in Parkinson's disease are essential for recognizing emotion in facial expressions.

The look of fear and anger: Facial maturity modulates recognition of fearful and angry expressions.

The current series of studies provide converging evidence that facial expressions of fear and anger may have co-evolved to mimic mature and babyish faces in order to enhance their communicative signal. In Studies 1 and 2, fearful and angry facial expressions were manipulated to have enhanced babyish features (larger eyes) or enhanced mature features (smaller eyes) and in the context of a speeded categorization task in Study 1 and a visual noise paradigm in Study 2, results indicated that larger eyes facilitated the recognition of fearful facial expressions, while smaller eyes facilitated the recognition of angry facial expressions. Study 3 manipulated facial roundness, a stable structure that does not vary systematically with expressions, and found that congruency between maturity and expression (narrow face-anger; round face-fear) facilitated expression recognition accuracy. Results are discussed as representing a broad co-evolutionary relationship between facial maturity and fearful and angry facial expressions.

Age differences in recognition of emotion in lexical stimuli and facial expressions.

Age differences in emotion recognition from lexical stimuli and facial expressions were examined in a cross-sectional sample of adults aged 18 to 85 (N = 357). Emotion-specific response biases differed by age: Older adults were disproportionately more likely to incorrectly label lexical stimuli as happiness, sadness, and surprise and to incorrectly label facial stimuli as disgust and fear. After these biases were controlled, findings suggested that older adults were less accurate at identifying emotions than were young adults, but the pattern differed across emotions and task types. The lexical task showed stronger age differences than the facial task, and for lexical stimuli, age groups differed in accuracy for all emotional states except fear. For facial stimuli, in contrast, age groups differed only in accuracy for anger, disgust, fear, and happiness. Implications for age-related changes in different types of emotional processing are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Behavioral comparisons of children from abusive and distressed families.

Investigated the problem behaviors of 35 physically abused 6–16 yr olds in comparison with 36 nonabused children from a child welfare agency and 35 nonabused children in the community. Parental report of behavioral strengths and weaknesses was examined by administering the Child Behavior Profile. Results concur with those of previous reports that abused children display a significantly greater number of behavior problems and fewer social competencies than normals. The behavior patterns of abused Ss closely resembled the range of behavior problems shown by Ss from distressed families in which abuse was not present.

You're only as pretty as you feel: Facial expression as a determinant of physical attractiveness.

In Exp I, photos of 15 female target persons posing happy, neutral, and sad facial expressions were rated by 257 undergraduates for facial attractiveness using paired comparisons and Likert scales. Half of the raters were instructed to compensate for the effects of facial expression. Paired comparisons and Likert ratings were highly correlated. Target persons were less attractive when posing sad expressions than when posing neutral or happy expressions, which did not differ. In addition, independent ratings of 4 dimensions of the target persons' facial expression were obtained: pleasantness, surprise, intensity, and naturalness. Changes in these dimensions from the neutral to the happy and sad expressions and the corresponding changes in attractiveness were consistently related only to pleasantness, supporting the reinforcement-affect theory of attraction. Exp II, with 21 male undergraduates, related overall attractiveness to facial and bodily attractiveness. Both facial and bodily attractiveness were predictive of overall attractiveness, but the face was a slightly more powerful predictor. Results are discussed with respect to the stability of physical attractiveness, and alternative explanations of the mental-illness/physical-unattractiveness relation are proposed.

Neural systems for recognition of emotional prosody: A 3-D lesion study.

Which brain regions are associated with recognition of emotional prosody? Are these distinct from those for recognition of facial expression? These issues were investigated by mapping the overlaps of co-registered lesions from 66 brain-damaged participants as a function of their performance in rating basic emotions. It was found that recognizing emotions from prosody draws on the right frontoparietal operculum, the bilateral frontal pole, and the left frontal operculum. Recognizing emotions from prosody and facial expressions draws on the right frontoparietal cortex, which may be important in reconstructing aspects of the emotion signaled by the stimulus. Furthermore, there were regions in the left and right temporal lobes that contributed disproportionately to recognition of emotion from faces or prosody, respectively.

Differentiation of personal distress and sympathy in children and adults.

The goals of this study were (a) to determine whether we could differentiate between sympathetic and distress reactions using facial and heart-rate markers as well as self-report indices; (b) to examine age and sex differences in markers of the two different modes of affective response; and (c) to examine the relations of questionnaire indices of empathy, parental attitudes toward the expression of emotion, and participants' social presentational concerns to indices of sympathy and distressed responding. Third and sixth graders and adults were induced to experience sympathy and distress with mood induction procedures. Heart-rate change differed across the two inductions, as did facial expressions (for sadness and sympathy, but not distress, facial expressions) and self-reported reactions (especially for females). Females exhibited more facial sympathy and reported more distress than males. The various markers of emotional response generally related predictably to questionnaire indices of empathy. There was some support for the notion that parents who encourage the expression of emotion by their children have children who score high on empathy and are relatively unlikely to experience personal distress in sympathy-evoking contexts.

Metacognition of emotional face recognition.

While humans are adept at recognizing emotional states conveyed by facial expressions, the current literature suggests that they lack accurate metacognitions about their performance in this domain. This finding comes from global trait-based questionnaires that assess the extent to which an individual perceives him or herself as empathic, as compared to other people. Those who rate themselves as empathically accurate are no better than others at recognizing emotions. Metacognition of emotion recognition can also be assessed using relative measures that evaluate how well a person thinks s/he has understood the emotion in a particular facial display as compared to other displays. While this is the most common method of metacognitive assessment of people's judgments of learning or their feelings of knowing, this kind of metacognition—“relative meta-accuracy”—has not been studied within the domain of emotion. As well as asking for global metacognitive judgments, we asked people to provide relative, trial-by-trial prospective and retrospective judgments concerning whether they would be right or wrong in recognizing the expressions conveyed in particular facial displays. Our question was: Do people know when they will be correct in knowing what expression is conveyed, and do they know when they do not know? Although we, like others, found that global meta-accuracy was unpredictive of performance, relative meta-accuracy, given by the correlation between participants' trial-by-trial metacognitive judgments and performance on each item, were highly accurate both on the Mind in the Eyes task (Experiment 1) and on the Ekman Emotional Expression Multimorph task (in Experiment 2).

Is this happiness I see? Biases in the identification of emotional facial expressions in depression and social phobia.

The present study was designed to examine the operation of depression-specific biases in the identification or labeling of facial expression of emotions. Participants diagnosed with major depression and social phobia and control participants were presented with faces that expressed increasing degrees of emotional intensity, slowly changing from a neutral to a full-intensity happy, sad, or angry expression. The authors assessed individual differences in the intensity of facial expression of emotion that was required for the participants to accurately identify the emotion being expressed. The depressed participants required significantly greater intensity of emotion than did the social phobic and the control participants to correctly identify happy expressions and less intensity to identify sad than angry expressions. In contrast, social phobic participants needed less intensity to correctly identify the angry expressions than did the depressed and control participants and less intensity to identify angry than sad expressions. Implications of these results for interpersonal functioning in depression and social phobia are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
