A vast body of literature shows that maternal depression has long-term adverse consequences for children. However, only very few studies have documented the effect of maternal depression on children's ability to process emotional expressions and even fewer incorporated measures of observed maternal sensitivity to further tease apart whether it is the symptoms per se or the associated impact via maternal sensitivity that affects children's developing emotion-processing abilities. In a large community sample of Dutch preschoolers (N = 770), we examined independent and mediated effects of maternal depressive symptoms and sensitivity on children's ability to recognize emotional expressions using a nonverbal and a verbal task paradigm. Maternal depressive symptoms predicted less accurate emotion labeling in children, while maternal sensitivity was associated with more accurate emotion matching, especially for sadness and anger. Maternal sensitivity did not mediate the observed associations between mothers' depressive symptoms and children's emotion recognition, and effects were similar for boys and girls. Given that maternal depressive symptoms and sensitivity affected nonoverlapping areas of young children's emotion recognition, prevention and intervention efforts should focus on both alleviating maternal depressive symptoms and improving maternal sensitivity at the same time in order to maximize benefit.

Background: Previous research highlights the significance of a functional polymorphism located in the promoter region (5-HTTLPR) of the serotonin transporter gene in emotional behaviour. This study examined the effect of the 5-HTTLPR polymorphism on emotion processing in a large number of healthy preschoolers., Methods: The 5-HTTLPR genotype was classified in 605 children as homozygous for the short allele (SS), homozygous for the long allele (LL), or heterozygous (LS). Emotion-processing was assessed using age-appropriate computer tasks where children matched happy, sad, angry, and fearful facial expressions preceded by a shape-matching task to assess basic matching ability., Results: We found that young children could differentiate between emotion categories (F = 12.1, p < .001). The effect of 5-HTTLPR genotype depended on the emotion category presented (F = 2.3, p = .031). This effect was explained by the finding that SS children were less accurate at recognising fearful faces than LL or LS children (F = 5.3, p = .005). We did not find any significant differences as a result of 5-HTTLPR genotype for happy, sad or angry expressions (p > .05)., Conclusions: Results indicate that 5-HTTLPR allele status selectively impacts the processing of fearful but not other facial expressions. This pattern is already apparent in very young typically developing children. Results may signal an early vulnerability for affective problems before disorders emerge., (© 2011 The Authors.

Very few large-scale studies have focused on emotional facial expression recognition (FER) in 3-year-olds, an age of rapid social and language development. We studied FER in 808 healthy 3-year-olds using verbal and nonverbal computerized tasks for four basic emotions (happiness, sadness, anger, and fear). Three-year-olds showed differential performance on the verbal and nonverbal FER tasks, especially with respect to fear. That is to say, fear was one of the most accurately recognized facial expressions as matched nonverbally and the least accurately recognized facial expression as labeled verbally. Sex did not influence emotion-matching nor emotion-labeling performance after adjusting for basic matching or labeling ability. Three-year-olds made systematic errors in emotion-labeling. Namely, happy expressions were often confused with fearful expressions, whereas negative expressions were often confused with other negative expressions. Together, these findings suggest that 3-year-olds' FER skills strongly depend on task specifications. Importantly, fear was the most sensitive facial expression in this regard. Finally, in line with previous studies, we found that recognized emotion categories are initially broad, including emotions of the same valence, as reflected in the nonrandom errors of 3-year-olds., (PsycINFO Database Record (c) 2011 APA, all rights reserved)

Objective: Although early-onset conduct problems predict both psychiatric and health problems in adult life, little research has been done to index neural correlates of conduct problems. Emerging research suggests that a subgroup of children with conduct problems and elevated levels of callous-unemotional traits may be genetically vulnerable to manifesting disturbances in neural reactivity to emotional stimuli indexing distress. Using functional MRI, the authors evaluated differences in neural response to emotional stimuli between boys with conduct problems and elevated levels of callous-unemotional traits and comparison boys., Method: Seventeen boys with conduct problems and elevated levels of callous-unemotional traits and 13 comparison boys of equivalent age (mean=11 years) and IQ (mean=100) viewed blocked presentations of fearful and neutral faces. For each face, participants distinguished the sex of the face via manual response., Results: Relative to the comparison group, boys with conduct problems and elevated levels of callous-unemotional traits manifested lesser right amygdala activity to fearful faces., Conclusions: This finding is in line with data from studies of adults with antisocial behavior and callous-unemotional traits (i.e., psychopaths), as well as from a recent study of adolescents with callous-unemotional traits, and suggests that the neural substrates of emotional impairment associated with callous-unemotional antisocial behavior are already present in childhood.

Previous studies indicate that Multiple Complex Developmental Disorder (MCDD) children differ from PDD-NOS and autistic children on a symptom level and on psychophysiological functioning. Children with MCDD (n = 21) and PDD-NOS (n = 62) were compared on two facets of social-cognitive functioning: identification of neutral faces and facial expressions. Few significant group differences emerged. Children with PDD-NOS demonstrated a more attention-demanding strategy of face processing, and processed neutral faces more similarly to complex patterns whereas children with MCDD showed an advantage for face recognition compared to complex patterns. Results further suggested that any disadvantage in face recognition was related more to the autistic features of the PDD-NOS group rather than characteristics specific to MCDD. No significant group differences emerged for identifying facial expressions.

Background: The impact of personal familiarity upon children's developing emotion-processing has been largely ignored in previous research, yet may prove particularly important given the emotional salience of such stimuli and children's greater exposure to familiar others compared to strangers. We examined the impact of personal familiarity upon developing facial expression recognition (FER)., Methods: Participants included 153 children, 4-15 years old. We employed dynamic expressions of five emotions (happy, sad, anger, fear, disgust), posed by familiar (parents, teachers) and unfamiliar identities., Results: Accuracy improved with age for recognising sad and fear expressions, but not anger. Children tended to correctly recognise happiness and fear at lower intensities. The impact of familiarity on FER depended on emotion-category. Familiarity did not affect recognition of sad expressions, but children were less accurate at recognising anger, fear, and disgust in familiar individuals compared to strangers., Conclusion: Personal familiarity may exert a distracting effect on children's performance. Findings highlight the importance of incorporating different emotion-categories and familiarity when examining the development of FER. Clinical implications are discussed.

There is debate in cognitive neuroscience whether conscious versus unconscious processing represents a categorical or a quantitative distinction. The purpose of the study was to explore this matter using functional magnetic resonance imaging (fMRI). We first established objective thresholds of the critical temporal parameters for overt and covert presentations of fear and disgust. Next we applied these stimulus parameters in an fMRI experiment to determine whether non-consciously perceived (covert) facial expressions of fear and disgust show the same double dissociation (amygdala response to fear, insula to disgust) observed with consciously perceived (overt) stimuli. A backward masking paradigm was used. In the psychophysics experiment, the following parameters were established: 30-ms target duration for the covert condition, and 170-ms target duration for the overt condition. Results of the block-design fMRI study indicated substantial differences underlying the perception of fearful and disgusted facial expressions, with significant effects of both emotion and target duration. Findings for the overt condition (170 ms) confirm previous evidence of amygdala activation to fearful faces, and insula activation to disgusted faces, and a double dissociation between these two emotions. In the covert condition (30 ms), the amygdala was not activated to fear, nor was the insula activated to disgust. Overall, findings demonstrate significant differences between the neural responses to fear and to disgust, and between the covert presentations of these two emotions. These results therefore suggest distinct neural correlates of conscious and unconscious emotion perception.

Altered patterns of facial expression recognition ( FER) have been linked to internalizing and externalizing problems in school children and adolescents. In a large sample of preschoolers ( N = 727), we explored concurrent and prospective associations between internalizing/externalizing problems and FER. Internalizing/externalizing problems were rated by parents at 18 and 36 months using the Child Behavior Checklist. FER was assessed at 36 months using age-appropriate computer tasks of emotion matching and emotion labeling. Internalizing problems were associated with emotion-specific differences at both ages: at 18 months they predicted more accurate labeling of sadness; at 36 months they were associated with less accurate labeling of happiness and anger. Externalizing problems at both ages were associated with general FER deficits, particularly for matching emotions. Findings suggest that in preschoolers, internalizing problems contribute to emotion-specific differences in FER, while externalizing problems are associated with more general FER deficits. Knowledge of the specific FER patterns associated with internalizing/externalizing problems can be proven useful in the refinement of emotion-centered preventive interventions.

• Adolescents with depression were marginally faster than those in the comparison group to recognise sadness, although this trend disappeared once covarying for age and use of antidepressant medication. • Within the depression group, severity of depression symptoms and borderline personality features were associated with poorer emotional facial expression recognition (EFER) performance. • Discrepancies between group and within-group differences may explain some of the clinical heterogeneity observed in studies of EFER amongst adolescents with depression. • Studying clinical features in relation to EFER in adolescents with depression allows for a more nuanced understanding of social difficulties that may be experienced in depression. Studies have reported that emotional facial expression recognition (EFER) may be altered in individuals with depression. This study examined EFER in adolescent girls with and without depression and further examined associations between relevant clinical features of depression and EFER. Fifty adolescent girls aged 12 to 19 years old meeting criteria for depression or subthreshold levels of symptomatology and 55 adolescent girls with no psychiatric diagnosis completed EFER tasks. Reaction time and accuracy for recognising expressions at high and low intensities, and sensitivity in recognising happiness, sadness, anger and fear were assessed. Data were analysed using linear mixed models. Adolescents with depression were marginally faster than those in the comparison group to recognize sadness, although this trend disappeared once covarying for age and antidepressant use. Amongst adolescents with depression, clinical features were associated with poorer EFER performance. In contrast, anxiety symptoms were linked to better accuracy and heightened sensitivity towards happiness. A better understanding of EFER in adolescent girls with and without depression, and how clinical features might be associated with altered patterns of EFER could help to explain clinical heterogeneity observed in such studies of adolescents with depression. Knowledge of socio-cognitive alterations associated with depression will help to better develop and tailor interventions. [ABSTRACT FROM AUTHOR]
