Social skills and nonverbal decoding of emotions in very preterm children at early school age

"Does facial emotion recognition mediate the relationship between preterm birth and social skills? - A meta-analysis"

BACKGROUND

Preterm birth (PB) is prevalent and associated with structural and functional brain alterations which may affect cognitive and behavioural outcomes, including social development. Facial emotion recognition (FER) is one of the main components of social interaction. PB individuals face distinct FER challenges that may impact social skills. Furthermore, both FER and social skills have shown distinctive developmental trajectories in PB individuals compared to term born controls. This study investigates the association between FER and social skills in PB individuals compared to term-born controls.

OBJECTIVES

To systematically review and meta-analyse relevant literature on the association between FER and social skills and to summarize the reported differences in FER and social skills between PB individuals and term-born controls of similar age.

METHOD

a systematic search of peer-reviewed and English written studies was performed in MEDLINE, Web of Science and CINAHL, with an additional forward and backward citation search. Eligible studies included any observational study that had a term-born control sample of similar age with reported FER and social skills measures and/or correlations between them. Quality assessment and data extraction was carried out. Correlation coefficients and Hedges' g for FER and social skills were calculated as effect size indexes. Random effects model and subgroup analysis considering gestational age and age at assessment was performed. Results were summarized using forest plots. I2 statistics and Cochran's Q were used to test for heterogeneity.

RESULTS

8 studies were included (PB = 410, controls =337). Only 3 studies explored the correlation between FER and social skills. The review found a higher correlation between FER and social skills in the PB group (Z = 0.18, CI = -0.03, 0.39) compared to controls (Z = 0.11, CI = -0.03, 0.25). FER was significantly lower in PB individuals (overall g = -1.48; 95%IC = -2.46, -0-5), particularly in very preterm and adolescent subgroups.

DISCUSSION

FER might play a crucial role in the social development of PB individuals compared to those born at term, but existing research in this domain remains limited.

Mri findings, looking behaviour and affect recognition in very preterm children: A pilot study

Children born very preterm often exhibit atypical gaze behaviors, affect recognition difficulties and are at risk for cerebral white matter damage. This study explored links between these sequalae. In 24 12-year-old children born very preterm, ventricle size using Evans and posterior ventricle indices, and corpus callosum area were used to measure white matter thickness. The findings revealed a correlation between less attention towards the eyes and larger ventricle size. Ventricle and posterior corpus callosum sizes were correlated to affect-recognition proficiency. Findings suggest a link between white matter damage, gaze behavior, and affect recognition accuracy, emphasizing a relation with social perception.

Emotion Recognition in Preterm and Full-Term School-Age Children

Children born preterm (<37 weeks’ gestation) show a specific vulnerability for socio-emotional difficulties, which may lead to an increased likelihood of developing behavioral and psychiatric problems in adolescence and adulthood. The accurate decoding of emotional signals from faces represents a fundamental prerequisite for early social interactions, allowing children to derive information about others’ feelings and intentions. The present study aims to explore possible differences between preterm and full-term children in the ability to detect emotional expressions, as well as possible relationships between this ability and socio-emotional skills and problem behaviors during everyday activities. We assessed 55 school-age children (n = 34 preterm and n = 21 full-term) with a cognitive battery that ensured comparable cognitive abilities between the two groups. Moreover, children were asked to identify emotional expressions from pictures of peers’ faces (Emotion Recognition Task). Finally, children’s emotional, social and behavioral outcomes were assessed with parent-reported questionnaires. The results revealed that preterm children were less accurate than full-term children in detecting positive emotional expressions and they showed poorer social and behavioral outcomes. Notably, correlational analyses showed a relationship between the ability to recognize emotional expressions and socio-emotional functioning. The present study highlights that early difficulties in decoding emotional signals from faces may be critically linked to emotional and behavioral regulation problems, with important implications for the development of social skills and effective interpersonal interactions.

Cognitive, Behavioral and Socioemotional Development in a Cohort of Preterm Infants at School Age: A Cross-Sectional Study

More than 50% of children who survive prematurity have an atypical course of development at school age, as environmental demands become more demanding. This study examines the effects of preterm birth on the cognitive, behavioral and socioemotional development of 185 children at ages five and seven years. Weaknesses were found in attention, working memory, processing speed and the ability to correctly interpret emotions at both ages five and seven. Significant correlations were found in regression and moderation models. These findings suggest that school-age children who were preterm infants are at increased risk of exhibiting impairments in several developmental domains that may affect their overall quality of life.

Newborn Neurobehavior Is Related to Later Neurodevelopment and Social Cognition Skills in Extremely Preterm-Born Children: A Prospective Longitudinal Cohort Study

Objective: The aim of this study was to evaluate the ability of the neonatal neurobehavioral characteristics to act as an indicator for later neurodevelopment and neurocognitive performance.

Methods: Sixty-six infants born extremely preterm (<28 gestational weeks) were followed until 6.5 years. Neurobehavior at term age was assessed by the behavior subscale of the Hammersmith Neonatal Neurological Examination (HNNE) using dichotomic rating, optimal, and non-optimal. The Griffiths Mental Developmental Scales (GMDS) at 2 years, and the Wechsler Intelligence Scales at 6.5 years, and a Neuropsychological Assessment at 6.5 years were used to assess neurodevelopment and neurocognitive performance including social cognition skills.

Results: An optimal auditory orientation at term age was associated with better developmental quotients (DQ) in Personal–Social, and Hearing–Language GMDS subscale at 2 years (p < 0.05). An optimal visual alertness was associated with better Total (p < 0.01), Locomotor (p < 0.001), and Eye–Hand Coordination (p < 0.01) DQs at 2 years, and with sensorimotor function (p < 0.001) and social perception (p < 0.01) tests at 6.5 years.

Conclusion: The neurobehavioral characteristics of newborns might serve as a precursor of social cognition skills and the HNNE behavior subscale offers a tool to identify infants at risk for later deficits in neurodevelopment and social cognition.

Altered Functional Connectivity During Face Processing in Children Born Very Low Birth Weight

Structural brain alterations have been reported in key emotional face processing regions following preterm birth; however, few studies have investigated the functional networks underlying these processes in children born with very low birth weight (VLBW). Using magnetoencephalography (MEG), we examined the functional networks related to the implicit processing of happy and angry faces in 5-year-old VLBW (n = 28) and full-term (FT; n = 24) children. We found that VLBW children showed atypical recruitment of emotional face processing networks in theta (4–7 Hz) compared to FT children. VLBW children showed reduced theta connectivity during processing of angry faces only. This hypo-connected theta-band network was anchored in the left orbitofrontal and parietal regions, involved in the higher level processing of faces and emotion regulation. At the behavioural level, despite VLBW children performing within the normal range, FT children had significantly higher affect recognition scores. Our MEG results suggest a selective impairment in processing angry faces, which would negatively impact social functioning in VLBW children. In FT children, greater recruitment of this theta-band network was positively associated with improved affect recognition scores. Thus, our findings suggest an important role of theta oscillations in early face processing, deficits which may contribute to broader socio-emotional impairments in VLBW children.

Neurodevelopmental origins of social competence in very preterm children

Social problems are an important feature of the preterm behavioral phenotype but are diverse and multidimensional. A model of social competence comprised of the three interrelated components of social cognition, social interaction, and social adjustment is useful in conceptualizing these problems. Weaknesses in social cognition in very preterm (VPT) children, although rarely studied, are found on tasks involving interpretation of social cues. Difficulties in social interaction in VPT infants and young children are documented by structured observations of their interactions with adults. Problems in social adjustment are endorsed on parent and teacher ratings of VPT infants and youth and on self-reports of VPT adults. These multiple deficits likely stem from early disruptions in neural development, are related to other consequences of preterm birth, and subject to postnatal environment influences. Further research is needed to more fully account for the effects of VPT birth on the development of social competence.

Social Adjustment in Adolescents Born Very Preterm: Evidence for a Cognitive Basis of Social Problems

OBJECTIVE

To increase the understanding of social adjustment and autism spectrum disorder symptoms in adolescents born very preterm by studying the role of emotion recognition and cognitive control processes in the relation between very preterm birth and social adjustment.

STUDY DESIGN

A Dutch cohort of 61 very preterm and 61 full-term adolescents aged 13 years participated. Social adjustment was rated by parents, teachers, and adolescents and autism spectrum disorder symptoms by parents. Emotion recognition was assessed with a computerized task including pictures of child faces expressing anger, fear, sadness, and happiness with varying intensity. Cognitive control was assessed using a visuospatial span, antisaccade, and sustained attention to response task. Performance measures derived from these tasks served as indicators of a latent cognitive control construct, which was tested using confirmatory factor analysis. Mediation analyses were conducted with emotion recognition and cognitive control as mediators of the relation between very preterm birth and social problems.

RESULTS

Very preterm adolescents showed more parent- and teacher-rated social problems and increased autism spectrum disorder symptomatology than controls. No difference in self-reported social problems was observed. Moreover, very preterm adolescents showed deficits in emotion recognition and cognitive control compared with full-term adolescents. The relation between very preterm birth and parent-rated social problems was significantly mediated by cognitive control but not by emotion recognition. Very preterm birth was associated with a 0.67-SD increase in parent-rated social problems through its negative effect on cognitive control.

CONCLUSIONS

The present findings provide strong evidence for a central role of impaired cognitive control in the social problems of adolescents born very preterm.

Converging function, structure, and behavioural features of emotion regulation in very preterm children

Children born very preterm (VPT; <32 weeks' gestational age) are at high risk for emotional regulation and social communication impairments. However, the underlying neurobiological correlates of these difficulties remain poorly understood. Using a multimodal approach, including both magnetoencephalographic and structural magnetic resonance imaging, we investigated the functional, structural, and behavioural characteristics of socio-emotional processing in 19 school-age children born VPT and 21 age-matched term-born (TB) children (7-13 years). Structural MRI analyses were conducted on a subset of these groups (16 VPT and 21 age-matched TB). Results showed that the inhibition of aversive socio-emotional stimuli was associated with a sustained reduction of right frontoparietal functional brain activity in children born VPT children. Moreover, whole brain structural analyses showed that reductions of cortical thickness or volume in these regions were associated with poor socio-emotional performance in children born VPT. Hence, our results suggest that functional and structural alterations encompassing the frontoparietal areas might be a biological marker of less efficient emotion regulation processes/performance in school-age children born VPT. These findings open up novel avenues to investigate the potential impact of such atypicalities, and in particular, those related to the atypical maturation of the medial prefrontal regions, on the frequent development of psychiatric disorders in this vulnerable population.

Do Infants Born Very Premature and Who Have Very Low Birth Weight Catch Up With Their Full Term Peers in Their Language Abilities by Early School Age?

PURPOSE

This study examined the extent to which children born preterm (< 37 weeks) and/or who have low birth weight (< 2,500 g) catch up with their full term peers in terms of their language abilities at early school age (≥ 5 to < 9 years).

METHOD

A systematic literature search identified empirical studies that fit the inclusion criteria. Data from the tests/questionnaires used for meta-analysis spanned the following language categories: total language score, expressive language, receptive language, pragmatics, phonological awareness, and grammar. The means (standard deviations) were extracted from the studies and were converted to mean difference and 95% confidence intervals to test for overall effect.

RESULTS

Sixteen studies met the inclusionary criteria, for a total of 2,739 participants, of which 1,224 were born full term and 1,515 were born preterm. It is important to note that the preterm cohort represented very preterm infants who have a very low birth weight. The meta-analysis found that preterm infants scored significantly worse on total language (p < .001), receptive language (p < .001), expressive language (p < .001), phonological awareness (p < .001), and grammar (p = .03) than their full term peers. However, preterm infants did not score significantly worse than their peers on their pragmatics (p = .19).

CONCLUSIONS

Children born VPT and who have VLBW perform worse than their peers on their total language, receptive language, expressive language, phonological awareness, and grammar abilities by early school age. This information is important for speech-language pathologists to consider as children born prematurely reach school age.

Social reasoning abilities in preterm and full-term children aged 5-7years

BACKGROUND

Literature has evidenced behavioral and socio-emotional problems in preterm children, as well as long-term difficulties to establish and maintain social relationships in preterm population. Several studies have shown relations between behavior and social reasoning abilities in typically developing children and adults.

AIM

The present study aimed to investigate the social understanding and social reasoning abilities in preterm children aged between 5 and 7years in comparison to their full-term peers.

STUDY DESIGN

A social resolution task (SRT) was used to assess abilities to judge, identify and reason about others' behavior in relation to conventional and moral rules knowledge.

SUBJECTS

102 preterm children and 88 full-term children were included in the study.

RESULTS

Compared with their full-term peers, preterm children exhibited difficulties to understand and reason about inappropriate social behavior, particularly for situations related to the transgression of conventional rules. They used more irrelevant information and exhibited less social awareness when reasoning about the transgression of social rules. The only significant predictor for global SRT and social reasoning scores was the mental processing composite of the K-ABC, but the part of the variance of the SRT that could be explained by the general cognitive abilities was relatively small.

CONCLUSION

Preterm children demonstrated poorer social knowledge and social reasoning abilities compared with full-term children at early school age. Improving such abilities may reduce behavioral difficulties and peer relationship problems often described in the preterm population. These findings emphasize the need to early identify children at risk for impaired social development.

Altered resting-state functional connectivity in emotion-processing brain regions in adults who were born very preterm

BACKGROUND

Very preterm birth (VPT; <32 weeks of gestation) has been associated with impairments in emotion regulation, social competence and communicative skills. However, the neuroanatomical mechanisms underlying such impairments have not been systematically studied. Here we investigated the functional integrity of the amygdala connectivity network in relation to the ability to recognize emotions from facial expressions in VPT adults.

METHOD

Thirty-six VPT-born adults and 38 age-matched controls were scanned at rest in a 3-T MRI scanner. Resting-state functional connectivity (rs-fc) was assessed with SPM8. A seed-based analysis focusing on three amygdalar subregions (centro-medial/latero-basal/superficial) was performed. Participants' ability to recognize emotions was assessed using dynamic stimuli of human faces expressing six emotions at different intensities with the Emotion Recognition Task (ERT).

RESULTS

VPT individuals compared to controls showed reduced rs-fc between the superficial subregion of the left amygdala, and the right posterior cingulate cortex (p = 0.017) and the left precuneus (p = 0.002). The VPT group further showed elevated rs-fc between the left superficial amygdala and the superior temporal sulcus (p = 0.008). Performance on the ERT showed that the VPT group was less able than controls to recognize anger at low levels of intensity. Anger scores were significantly associated with rs-fc between the superficial amygdala and the posterior cingulate cortex in controls but not in VPT individuals.

CONCLUSIONS

These findings suggest that alterations in rs-fc between the amygdala, parietal and temporal cortices could represent the mechanism linking VPT birth and deficits in emotion processing.

Preterm birth is associated with atypical social orienting in infancy detected using eye tracking

BACKGROUND

Preterm birth is closely associated with neurocognitive impairment in childhood including increased risk for social difficulties. Eye tracking objectively assesses eye-gaze behaviour in response to visual stimuli, which permits inference about underlying cognitive processes. We tested the hypothesis that social orienting in infancy is altered by preterm birth.

METHODS

Fifty preterm infants with mean (range) gestational age (GA) at birth of 29(+1) (23(+2) -33(+0) ) weeks and 50 term infants with mean (range) GA at birth 40(+2) (37(+0) -42(+3) ) weeks underwent eye tracking at median age of 7 months. Infants were presented with three categories of social stimuli of increasing complexity. Time to first fixate (TFF) and looking time (LT) on areas of interest (AoIs) were recorded using remote eye tracking.

RESULTS

Preterm infants consistently fixated for a shorter time on social content than term infants across all three tasks: face-scanning (fixation to eyes minus mouth 0.61s vs. 1.47s, p = .013); face pop-out task (fixation to face 0.8s vs. 1.34s, p = .023); and social preferential looking (1.16s vs. 1.5s p = .02). Time given to AoIs containing social content as a proportion of LT at the whole stimulus was lower in preterm infants across all three tasks. These results were not explained by differences in overall looking time between the groups.

CONCLUSIONS

Eye tracking provides early evidence of atypical cognition after preterm birth, and may be a useful tool for stratifying infants at risk of impairment for early interventions designed to improve outcome.

Socio-Emotional Development Following Very Preterm Birth: Pathways to Psychopathology

Very preterm birth (VPT; < 32 weeks of gestation) has been associated with an increased risk to develop cognitive and socio-emotional problems, as well as with increased vulnerability to psychiatric disorder, both with childhood and adult onset. Socio-emotional impairments that have been described in VPT individuals include diminished social competence and self-esteem, emotional dysregulation, shyness and timidity. However, the etiology of socio-emotional problems in VPT samples and their underlying mechanisms are far from understood. To date, research has focused on the investigation of both biological and environmental risk factors associated with socio-emotional problems, including structural and functional alterations in brain areas involved in processing emotions and social stimuli, perinatal stress and pain and parenting strategies. Considering the complex interplay of the aforementioned variables, the review attempts to elucidate the mechanisms underlying the association between very preterm birth, socio-emotional vulnerability and psychopathology. After a comprehensive overview of the socio-emotional impairments associated with VPT birth, three main models of socio-emotional development are presented and discussed. These focus on biological vulnerability, early life adversities and parenting, respectively. To conclude, a developmental framework is used to consider different pathways linking VPT birth to psychopathology, taking into account the interaction between medical, biological, and psychosocial factors.

A Preliminary Study of Depressive Symptoms in Mothers of 3-Year-Old Prematurely Born Children

This exploratory study examined the effects of maternal depressive symptoms on mothers' perceptions of their 3-year-old prematurely born children, interactive behaviors, and child outcomes. Mother and child interactive behaviors were coded from naturalistic observations in their homes. Education and marital status were found to be significantly related to maternal depressive symptoms. Factor analyses were conducted to determine the most prominent behaviors related to maternal depressive symptoms. In a small sample of mothers, the quality of the maternal-child relationship was negatively affected by elevated depressive symptoms. Mothers of prematurely born children may report depressive symptoms that continue into early childhood.

Social perception in children born at very low birthweight and its relationship with social/behavioral outcomes

BACKGROUND

Research has shown that children born very prematurely are at substantially elevated risk for social and behavioral difficulties similar to those seen in full-term children with autism spectrum disorders (ASDs).

METHODS

To gain insight into core deficits that may underlie these difficulties, in this study, we assessed the social perceptual skills of 8- to 11-year-old children born at very low birthweight (VLBW) (<1,500 g) and age-matched, full-term controls, using the Child and Adolescent Social Perception Measure. We also assessed social and behavioral outcomes with two parent-report measures used in ASD screening.

RESULTS

Children in the preterm group had normal range estimated verbal IQ. However, we found that they were impaired in their ability to use nonverbal cues from moving faces and bodies, and situational cues, to correctly identify the emotions of characters depicted in videotaped social interactions. Their performance on this task was related to the number of 'autistic-like' traits they displayed.

CONCLUSIONS

This research highlights links between social perceptual deficits and poor social and behavioral outcomes in children born very prematurely. The results also suggest that even those who have escaped major intellectual/language problems are at risk for social and behavioral problems that can be of clinical concern.

Characteristic Processes in Close Peer Friendships of Preterm Infants at Age 12

Close friendships become important at middle-school age and are unexplored in adolescents born prematurely. The study aimed to characterize friendship behaviors of formerly preterm infants at age 12 and explore similarities and differences between preterm and full-term peers on dyadic friendship types. From the full sample of N=186, one hundred sixty-six 12-year-old adolescents (40 born full term, 126 born preterm) invited a close friend to a 1.5 hour videotaped laboratory play session. Twenty adolescents were unable to participate due to scheduling conflicts or developmental disability. Characteristic friendship behaviors were identified by Q-sort followed by Q-factoring analysis. Friendship duration, age, and contact differed between the full-term and preterm groups but friendship activities, behaviors, and quality were similar despite school service use. Three Q-factors, leadership, distancing, and mutual playfulness, were most characteristic of all dyads, regardless of prematurity. These prospective, longitudinal findings demonstrate diminished prematurity effects at adolescence in peer friendship behavior and reveal interpersonal dyadic processes that are important to peer group affiliation and other areas of competence.
