Adult judgments and fine-grained analysis of infant facial expressions: Testing the validity of a priori coding formulas.

Three studies tested whether infant facial expressions selected to fit Max formulas (C. E. Izard, 1983) for discrete emotions are recognizable signals of those emotions. Forced-choice emotion judgments (Study 1) and emotion ratings (Study 2) by naive Ss fit Max predictions for slides of infant joy, interest, surprise, and distress, but Max fear, anger, sadness, and disgust expressions in infants were judged as distress or as emotion blends in both studies. Ratings of adult facial expressions (Study 2 only) fit a priori classifications. In Study 3, the facial muscle components of faces shown in Studies 1 and 2 were coded with the Facial Action Coding System (FACS; P. Ekman and W. V. Friesen, 1978) and Baby FACS (H. Oster and D. Rosenstein, in press). Only 3 of 19 Max-specified expressions of discrete negative emotions in infants fit adult prototypes. Results indicate that negative affect expressions are not fully differentiated in infants and that empirical studies of infant facial expressions are needed.

Differentiation in preschooler's categories of emotion.

Two studies (N = 68, ages 2;0–3;11; N = 80, ages 2;6–4;11) explore the idea that, rather than starting with a separate mental category for each discrete emotion, children start with two broad categories (positive and negative) and then differentiate within each until adult-like categories form. Children generated emotion labels for (a) facial expressions or (b) stories about an emotion's cause and consequence. Emotions included were happiness, anger, fear, sadness, and disgust. Both conditions yielded the predicted pattern of differentiation. These studies of younger children found the face more powerful in eliciting correct emotion labels than had prior research, which typically relied on older preschoolers.

Are max-specified infant facial expressions during face-to-face interaction consistent with differential emotions theory?

Differential emotions theory (DET) proposes that infant facial expressions of emotions are differentiated. To test this hypothesis, the authors examined infant facial expressions longitudinally at 2, 4, and 6 mo of age during face-to-face play and a "still-face" interaction with their mothers. Infant expressions were coded using the Maximally Discriminative Facial Movement Coding System (Max). Consistent with DET, discrete positive expressions occurred more of the time and were of longer duration than blended expressions of positive affect. Contrary to DET, at no age did the proportions or durations of discrete and blended negative expressions differ, and they showed different patterns of developmental change. One is led to either reject or revise DET or else question the adequacy of the Max system. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The influence of mother–child emotion regulation strategies on children's expression of anger and sadness.

In a sample of 153 children from preschool through second grade, relations between the use of emotion regulation strategy and children's expression of anger and sadness were coded during an observational task in which children were intentionally disappointed in the presence of the mother. Multilevel modeling was used to examine strategy use and current and subsequent expressions of anger and sadness. Results indicate that mothers' use of attention refocusing and joint mother–child cognitive reframing lead to lower intensity of expressed anger and sadness. Younger children expressed more sadness than older children, and maternal attention refocusing was less successful among older children than younger ones. Implications of these results for assessing the socialization of emotion regulation in preschool and school-age children are discussed.

When frustration is repeated: Behavioral and emotion responses during extinction over time.

Persistence of instrumental responding and negative facial expressions in response to repeated goal blockage was studied in 53 4-month-old infants. All participants experienced 2 sessions comprising baseline (no stimulation), contingency (stimulation resulting from infant action), and extinction (no stimulation) on consecutive days. Performance criteria identified 2 groups of infants, those who learned in Session 1 (Learning Group 1) and those who learned in Session 2 (Learning Group 2). Individual differences in instrumental responses and facial expression during extinction were compared as a function of learning group. Across sessions, the repetition of extinction for Learning Group 1 was associated with both a persistent instrumental response and anger expressions. The level of instrumental response and anger expression was equivalent to that observed for Learning Group 2 but only in Session 2, the day on which that group learned. Sadness and anger/sadness blended expressions were initially more common in Learning Group 2, but these expressions were attenuated given another exposure to the contingency in Session 2. Implications for the relations among infant emotion, cognition, and behavior are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Anger and advancement versus sadness and subjugation: The effect of negative emotion expressions on social status conferral.

Four studies examined status conferral (decisions about who should be granted status). The studies show that people confer more status to targets who express anger than to targets who express sadness. In the 1st study, participants supported President Clinton more when they viewed him expressing anger about the Monica Lewinsky scandal than when they saw him expressing sadness about the scandal. This effect was replicated with an unknown politician in Study 2. The 3rd study showed that status conferral in a company was correlated with peers' ratings of the workers' anger. In the final study, participants assigned a higher status position and a higher salary to a job candidate who described himself as angry as opposed to sad. Furthermore, Studies 2–4 showed that anger expressions created the impression that the expresser was competent and that these perceptions mediated the relationship between emotional expressions and status conferral.

Facial expressivity in infants of depressed mothers.

Examined facial expressions in 84 3-mo-old infants of mothers classified as depressed, nondepressed, or low scoring on the Beck Depression Inventory. Mother–infant dyads were videotaped during a 3-min face-to-face interaction, and the videotapes were coded by using the AFFEX facial expression coding system. Infants of both depressed and low-scoring mothers showed significantly more sadness and anger expressions and fewer interest expressions than infants of nondepressed mothers.

Infants' responses to their mothers' expressions of joy and sadness.

On separate visits to the laboratory, 36 nine-month-old infants (18 boys and 18 girls) watched their mothers express joy or sadness, facially and vocally, during a 2-min emotion-induction period. After the induction period, mothers continued to express joy or sadness while their infants played with four sets of toys. Infant emotion expressions were analyzed using the Max (Izard, 1979a) and Affex (Izard, Dougherty, & Hembree, 1983) coding systems, and infant play behavior was coded with a system developed by Belsky and Most (1981). The amount of time that the infants looked at their mothers was also measured. Findings were generally consistent with differential emotions theory (Izard, 1979b). The infants expressed more joy and looked longer at their mothers during the joy condition and they showed more sadness, anger, and gaze aversion during the sadness condition. The infants engaged in more play behavior in the joy condition than in the sadness condition. Regression analyses revealed several significant relations between infants' gaze behavior, emotion expressions, and play behavior. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The expression of determination: Similarities between anger and approach-related positive affect.

In this set of studies, we examine the perceptual similarities between emotions that share either a valence or a motivational direction. Determination is a positive approach-related emotion, whereas anger is a negative approach-related emotion. Thus, determination and anger share a motivational direction but are opposite in valence. An implemental mind-set has previously been shown to produce high-approach-motivated positive affect. Thus, in Study 1, participants were asked to freely report the strongest emotion they experienced during an implemental mind-set. The most common emotion reported was determination. On the basis of this result, we compared the facial expression of determination with that of anger. In Study 2, naive judges were asked to identify photographs of facial expressions intended to express determination, along with photographs intended to express basic emotions (joy, anger, sadness, fear, disgust, neutral). Correct identifications of intended determination expressions were correlated with misidentifications of the expressions as anger but not with misidentifications as any other emotion. This suggests that determination, a high-approach-motivated positive affect, is perceived as similar to anger. In Study 3, naive judges quantified the intensity of joy, anger, and determination expressed in photographs. The intensity of perceived determination was directly correlated with the intensity of perceived anger (a high-approach-motivated negative affect) and was inversely correlated with the intensity of perceived joy (a low-approach-motivated positive affect). These results demonstrate perceptual similarity between emotions that share a motivational direction but differ in valence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Maternal emotional signaling: Its effect on the visual cliff behavior of 1-year-olds.

Studied the effect of maternal facial expressions of emotion on 108 12-mo-old infants in 4 studies. The deep side of a visual cliff was adjusted to a height that produced no clear avoidance and much referencing of the mother. In Study 1, 19 Ss viewed a facial expression of joy, while 17 Ss viewed one of fear. In Study 2, 15 Ss viewed interest, while 18 Ss viewed anger. In Study 3, 19 Ss viewed sadness. In Study 4, 23 Ss were used to determine whether the expressions influenced Ss' evaluation of an ambiguous situation or whether they were effective in controlling behavior merely because of their discrepancy or unexpectedness. Results show that Ss used facial expressions to disambiguate situations. If a mother posed joy or interest while S referenced, most Ss crossed the deep side. If a mother posed fear or anger, few Ss crossed. In the absence of any depth whatsoever, few Ss referenced the mother and those who did, while the mother was posing fear, hesitated but crossed nonetheless. It is suggested that facial expressions regulate behavior most clearly in contexts of uncertainty. (17 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of arousal on judgments of others' emotions.

Previous evidence indicates that arousal cues information from memory associated with a similar level of arousal and that people will base judgments on the information that is most available to them. The present authors hypothesized that (a) increases in arousal would increase the likelihood that Ss would interpret positive statements and positive facial expressions as indicating a positive emotion associated with high arousal (joy) rather than a positive emotion associated with low arousal (serenity), and (b) increases in arousal would increase the likelihood that Ss would interpret negative statements and negative expressions as indicating a negative emotion associated with high arousal (anger) rather than a negative emotion associated with low arousal (sadness or depression). Two studies, with 37 adults and 38 students, tested the hypotheses. Results of each study support the 1st but not the 2nd hypothesis. Explanations for why arousal had the predicted effects on positive but not on negative stimuli are offered. (37 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Making faces: Age and emotion differences in the posing of emotional expressions.

Preschool children, 2 to 5 years of age, and adults posed the six facial expressions of happiness, surprise, anger, fear, sadness, and disgust before a videotape camera. Their poses were scored subsequently using the MAX system. The number of poses that included all components of the target expression (complete expressions) as well as the frequency of those that included only some of the components of the target expressions (partial expressions) were analyzed. Results indicated that 2-year-olds as a group failed to pose any face. Three-year-olds were a transitional group, posing happiness and surprise expressions but none of the remaining faces to any degree. Four- and 5-year-olds were similar to one another and differed from adults only on surprise and anger expressions. Adults were able to pose both these expressions. No group, including adults, posed fear and disgust well. Posing of happiness showed no change after 3 years of age. Consistent differences between partial and complete poses were observed particularly for the negative expressions of sadness, fear, and disgust. Implications of these results for socialization theories of emotion are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Children's expression of negative affect: Reasons and methods.

This study examined the influence of socialization figures (mother, father, best friend, medium friend), emotion type (anger, sadness, physical pain), age, and gender on 66 2nd and 71 5th-grade children's reasons for and methods of affect expression. Children reported expressing sadness in order to receive support, expressing pain because they perceived it was uncontrollable, and regulating anger due to negative consequences. Girls reported using verbal means to communicate emotion, whereas boys cited mild aggressive methods. Younger children indicated expressing emotion to receive assistance because they lack regulation skills, and to adhere to norms. Children expressed emotion in passive ways to fathers more than peers, and mothers were deemed by younger children as most accepting of displays of anger.

Consistency, specificity, and correlates of negative emotions.

Four studies with college student participants examined the consistency, specificity, and correlates of sadness, fear, and anger. Study 1 measured emotions with daily diaries, and Study 2 examined the relationship between trait emotions and state emotions. Studies 1 and 2 indicated that specific negative emotions are temporally stable, are positively correlated, and provide information above and beyond that provided by other negative emotions. Study 3 found that negative emotions are differentially associated with different facets of cognitive style, as measured by questionnaires that examined dysfunctional attitudes and attributions concerning negative events. Study 4 indicated that negative emotions are differentially associated with different facets of response style, as measured by the degree to which individuals described their thoughts, feelings, and actions in response to hypothetical events.

A comparison of two systems that code infant affective expression.

The Monadic Phases Coding System (MP) and the Maximally Discriminative Facial Movement Coding System (MAX) are both widely used to define and quantify categories of infant affective behavior. To evaluate the validity of extrapolating research findings from one system to another, we used both systems to code videotapes of 12 four-month-old infants engaged in mother–infant interaction. Interobserver agreement was higher with MP; interobserver reliability was equivalent. Point estimates for the percentages of negative and positive, but not interest, expressions were equivalent. MP and MAX generally agreed about the type of expression presented. Intersystem correlations supported the concurrent, but not discriminant, validity of MP and MAX categories. Interest expressions were not orthogonal to negative and positive affect. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The young infant's ability to produce discrete emotion expressions.

Five studies investigated the young infant's ability to produce identifiable emotion expressions as defined in differential emotions theory. Trained judges applied emotion-specific criteria in selecting expression stimuli from videotape recordings of 54 1–9 mo old infants' responses to a variety of incentive events, ranging from playful interactions to the pain of inoculations. Four samples of untrained Ss (130 undergraduates and 62 female health service professionals) confirmed the social validity of infants' emotion expressions by reliably identifying expressions of interest, joy, surprise, sadness, anger, disgust, contempt, and fear. Brief training resulted in significant increases in the accuracy of discrimination of infants' negative emotion expressions for low-accuracy Ss. Construct validity for the 8 emotion expressions identified by untrained Ss and for a consistent pattern of facial responses to unanticipated pain was provided by expression identifications derived from an objective, theoretically structured, anatomically based facial movement coding system.

Patterns of emotion expression during separation in the strange-situation procedure.

The facial expressions of 28 13-mo-old middle-class children were videotaped during the 3-min separation episode of the Ainsworth strange-situation procedure (ASSP). Facial behavior was analyzed to determine the patterns of emotional expressions during separation and to assess the relations between these patterns and types of attachment as assessed by the ASSP. Findings reveal that anger was the dominant negative emotion expressed by the majority of Ss in each of 3 ad hoc groups determined by level of negative emotion. Some high-negative emotion expressers displayed predominantly anger and others mainly sadness. Patterns of emotion expression varied with type of attachment; Ss who showed an insecure-resistant attachment pattern displayed less interest and more sadness than Ss in the securely attached groups. The proportion of time anger was expressed did not differ significantly with type of attachment. (20 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Anger management: Age differences in emotional modulation of visual processing.

Although positive and negative images enhance the visual processing of young adults, recent work suggests that a life-span shift in emotion processing goals may lead older adults to avoid negative images. To examine this tendency for older adults to regulate their intake of negative emotional information, the current study investigated age-related differences in the perceptual boost received by probes appearing over facial expressions of emotion. Visually-evoked event-related potentials were recorded from the scalp over cortical regions associated with visual processing as a probe appeared over facial expressions depicting anger, sadness, happiness, or no emotion. The activity of the visual system in response to each probe was operationalized in terms of the P1 component of the event-related potentials evoked by the probe. For young adults, the visual system was more active (i.e., greater P1 amplitude) when the probes appeared over any of the emotional facial expressions. However, for older adults, the visual system displayed reduced activity when the probe appeared over angry facial expressions. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
