Individual differences in neonatal “imitation” fail to predict early social cognitive behaviour

The influential hypothesis that humans imitate from birth – and that this capacity is foundational to social cognition – is currently being challenged from several angles. Most prominently, the largest and most comprehensive longitudinal study of neonatal imitation to date failed to find evidence that neonates copied any of nine actions at any of four time points (Oostenbroek et al., [2016] Current Biology, 26, 1334–1338). The authors of an alternative and statistically liberal post‐hoc analysis of these same data (Meltzoff et al., [2017] Developmental Science, 21, e12609), however, concluded that the infants actually did imitate one of the nine actions: tongue protrusion. In line with the original intentions of this longitudinal study, we here report on whether individual differences in neonatal “imitation” predict later‐developing social cognitive behaviours. We measured a variety of social cognitive behaviours in a subset of the original sample of infants (N = 71) during the first 18 months: object‐directed imitation, joint attention, synchronous imitation and mirror self‐recognition. Results show that, even using the liberal operationalization, individual scores for neonatal “imitation” of tongue protrusion failed to predict any of the later‐developing social cognitive behaviours. The average Spearman correlation was close to zero, mean r_s = 0.027, 95% CI [?0.020, 0.075], with all Bonferroni adjusted p values > .999. These results run counter to Meltzoff et al.'s rebuttal, and to the existence of a “like me” mechanism in neonates that is foundational to human social cognition.     

Gender‐related differences in neonatal imitation

Socio‐emotional behaviour is in part sex‐related in humans, although the contribution of the biological and socio‐cultural factors is not yet known. This study explores sex‐related differences during the earliest communicative exchange, the neonatal imitation in 43 newborn infants (3–96 hours old) using an index finger extension imitative gesture. Results showed that although the experimenter presented comparable stimuli to both sexes, and the total number of movements was similar in boys and girls, girls showed more fine motor movements, a higher number of specific imitative gestures, responded faster during the imitation and showed a higher baseline heart rate during the experiment. Newborn girls, with their faster and more accurate imitative abilities, may create a more responsive and interactive social environment, which in turn may lead to differences in socio‐emotional and cognitive development between girls and boys.

The Effects of Socio‐Economic Status on Infant Attention

The development of visual attention is a key component of cognitive functioning in infancy and childhood. By the time children in poverty reach school, deficits in attention are readily apparent; however, when these attention delays manifest is unknown. The current study tested attention longitudinally at 6, 9 and 12 months in infants from high‐socio‐economic status (SES) and low‐SES families. Infants were tested in a free play attention task in both simple and complex conditions, and two measures each of attention and inattention were scored. High‐SES infants showed greater attention overall and greater increases in attention when the stimuli were more complex. Low‐SES infants showed higher inattention than their high‐SES peers at all ages and were less likely to modulate their attention on the basis of stimulus complexity. Thus, by 6 months of age, low‐income infants already show deficits in attention. Results are discussed in terms of adaptability, implications for social development and attention interventions.

The role of emotion knowledge in the links between shyness and children's socio‐emotional functioning at preschool

The present study investigated the potential protective role of components of emotion knowledge (i.e., emotion recognition, situation knowledge) in the links between young children's shyness and indices of socio‐emotional functioning. Participants were n = 163 children (82 boys and 81 girls) aged 23–77 months (M = 53.29, SD = 14.48), recruited from preschools in Italy. Parents provided ratings of child shyness and teachers rated children's socio‐emotional functioning at preschool (i.e., social competence, anxiety‐withdrawal, peer rejection). Children were also interviewed to assess their abilities to recognize facial emotional expressions and identify situations that affect emotions. Among the results, shyness was positively related to anxiety‐withdrawal and peer rejection. In addition, emotion recognition was found to significantly moderate the links between shyness and preschool socio‐emotional functioning, appearing to serve a buffering role. For example, at lower levels of emotion recognition, shyness was positively associated with both anxiety‐withdrawal and rejection by peers, but at higher levels of emotion recognition, these associations were attenuated. Results are discussed in terms of the protective role of emotion recognition in promoting shy children's positive socio‐emotional functioning within the classroom context.     

Child care quality and Dutch 2‐ and 3‐year‐olds' socio‐emotional outcomes: Does the amount of care matter?

High amounts of early child care have sometimes been linked to higher levels of behaviour problems, while high‐quality child care has more often been related to fewer behaviour problems and more social competence. The current study investigated whether the level of centre emotional and behavioural support (child care quality) interacted with the amount of child care in predicting children's socio‐emotional behaviour. Participants were 417 children (mean age = 27 months) from 61 Dutch daycare centres. The amount of daycare ranged from 1 to 5 days per week (M = 2.3 days). Multi‐level analyses showed that, independent of the amount of daycare, high levels of centre emotional and behavioural support were related to more caregiver‐rated social competence 1 year later. In addition, children spending 3.5 days or more in highly supportive daycare centres showed the lowest levels of parent‐rated externalizing behaviour 1 year later. The findings emphasize (a) that the combined effects of the amount and quality of child care are important and (b) that high‐quality early child care is related to children's socio‐emotional development. Further policy, practice, and research implications are discussed.

Highlights

• We studied in a Dutch sample how the amount and quality of daycare interacted in relation to children's socio‐emotional outcomes.
• High levels of daycare quality were related to more teacher‐rated social competence.
• Children spending 3.5 days or more in highly supportive daycare centers showed less parent‐rated externalizing behavior.

     

Loneliness,HPA stress reactivity and social threat sensitivity: Analyzing naturalistic social challenges

Loneliness has been linked to poor health through an increased activation of threat surveillance mechanisms, such as the hypothalamic‐pituitary‐adrenal axis (HPA ). The socio‐cognitive model (Cacioppo & Hawley) proposes that lonely people have an increased social threat sensitivity which activates the HPA axis. The current study examined the impact of loneliness on HPA stress reactivity and social threat sensitivity in response to naturally occurring social challenges. Participants (N = 45) were prospective undergraduates attending a 3‐day university preparation programme over the summer, prior to commencing their university studies. Cortisol levels and perceived stress were measured before and after an ice breaker session on Day 1 and a lecture session on Day 3. Social threat sensitivity was also measured on the first and third day. When meeting unfamiliar peers in the ice breaker session, HPA stress reactivity was evident, but it was not markedly different in those who reported high levels of loneliness than those with low levels. The high loneliness group had higher levels of perceived stress and increased social threat sensitivity than the low loneliness group on both testing days. The findings show partial support for the socio‐cognitive model of loneliness because increased threat sensitivity was demonstrated in the high loneliness group. The findings indicate that lonely people do not respond in a physiologically different way to specific social challenges, but they typically report higher social threat sensitivity and higher perceived stress than their non‐lonely peers.     

What enhances the development of emotion understanding in young children? A longitudinal study of interpersonal predictors

We studied potential determinants of the development of children's emotion understanding (EU) from age 4 to 6 in a Norwegian community sample (N = 974) using the Test of Emotion Comprehension. Interpersonal predictors included the accuracy of parental mentalization, parental emotional availability, and teacher‐reported child social skills. Intrapersonal child factors were child gender and verbal skills. Overall, children's EU increased significantly over time. After adjusting for child gender, age‐4 EU, and parental socio‐economic status, greater child verbal and social skills and greater parental mentalization each uniquely predicted growth in EU. Results are discussed in terms of theory and research on children's EU and parents' emotion socialization.     

Neonatal imitation predicts how infants engage with faces

In human infants, neonatal imitation and preferences for eyes are both associated with later social and communicative skills, yet the relationship between these abilities remains unexplored. Here we investigated whether neonatal imitation predicts facial viewing patterns in infant rhesus macaques. We first assessed infant macaques for lipsmacking (a core affiliative gesture) and tongue protrusion imitation in the first week of life. When infants were 10–28 days old, we presented them with an animated macaque avatar displaying a still face followed by lipsmacking or tongue protrusion movements. Using eye tracking technology, we found that macaque infants generally looked equally at the eyes and mouth during gesture presentation, but only lipsmacking‐imitators showed significantly more looking at the eyes of the neutral still face. These results suggest that neonatal imitation performance may be an early measure of social attention biases and might potentially facilitate the identification of infants at risk for atypical social development.     

Socioeconomic status, resources, psychological experiences, and emotional responses: a test of the reserve capacity model

The current study used ecological momentary assessment to test several tenets of the reserve capacity model (L.C. Gallo & K. A. Matthews, 2003). Women (N = 108) with varying socioeconomic status (SES) monitored positive and negative psychosocial experiences and emotions across 2 days. Measures of intrapsychic and social resources were aggregated to represent the reserve capacity available to manage stress. Lower SES was associated with less perceived control and positive affect and more social strain. Control and strain contributed to the association between SES and positive affect. Lower SES elicited greater positive but not negative emotional reactivity to psychosocial experiences. Women with low SES had fewer resources relative to those with higher SES, and resources contributed to the association between SES and daily experiences.     

SES differences in language processing skill and vocabulary are evident at 18 months

This research revealed both similarities and striking differences in early language proficiency among infants from a broad range of advantaged and disadvantaged families. English‐learning infants (n = 48) were followed longitudinally from 18 to 24 months, using real‐time measures of spoken language processing. The first goal was to track developmental changes in processing efficiency in relation to vocabulary learning in this diverse sample. The second goal was to examine differences in these crucial aspects of early language development in relation to family socioeconomic status (SES). The most important findings were that significant disparities in vocabulary and language processing efficiency were already evident at 18 months between infants from higher‐ and lower‐SES families, and by 24 months there was a 6‐month gap between SES groups in processing skills critical to language development.     

From negative reactivity to empathic responding: Infants high in negative reactivity express more empathy later in development,with the help of regulation

Empathy has great effect on human well‐being, promoting healthy relationships and social competence. Although it is increasingly acknowledged that infants show empathy toward others, individual differences in infants’ empathy from the first year of life have rarely been investigated longitudinally. Here we examined how negative reactivity and regulation, two temperament traits that predict empathic responses in older children and adults, relate to infants’ empathy. Infants were studied at the ages of nine (N = 275) and 18 (N = 301) months (194 infants were studied at both ages). Empathic responses were assessed by infants’ observed reactions to an experimenter's simulated distress. Negative reactivity (fear, sadness, and distress to limitations) and regulation (soothability and effortful control) were assessed by parental reports. Negative reactivity was also examined by infants’ observed reactions to an adult stranger (fear) and during interaction with their mothers (displays of sadness/distress). When examined cross‐sectionally, infants’ fear and distress to limitations associated with self‐distress in response to others’ distress. In contrast, when examined longitudinally, early sadness and distress to limitations, but not fear, associated with later empathic concern and inquisitiveness. Moreover, this longitudinal relation was moderated by infants’ soothability and was evident only for children that had high soothability by the later time‐point. Our findings suggest that infants who at an earlier age show negative reactivity, react later in development with more empathy if they achieve sufficient regulation abilities. By that, the findings stress the developmental nature of temperament–empathy relations during infancy.     

Individual differences in executive function partially explain the socioeconomic gradient in middle‐school academic achievement

Children from families with low socioeconomic status (SES) earn lower grades, perform worse on achievement tests, and attain less education on average than their peers from higher‐SES families. We evaluated neurocognitive mediators of SES disparities in achievement in a diverse sample of youth whose data were linked to administrative records of performance on school‐administered tests of 7th grade reading and math proficiency (N = 203). We used structural equation modeling to evaluate whether associations between SES (measured at ages 8–9) and achievement (measured at age 13) are mediated by verbal ability and executive function (measured at age 10), a suite of top‐down mental processes that facilitate control of thinking and behavior. Children from relatively higher‐SES families performed better than their lower‐SES peers on all neurocognitive and achievement measures, and SES disparities in both reading and math achievement were partially mediated by variation in executive function, but not verbal ability. SES disparities in executive function explained approximately 37% of the SES gap in math achievement and 17% of the SES gap in reading achievement. Exploratory modeling suggests that SES‐related variation in working memory may play a particularly prominent role in mediation. We discuss potential implications of these findings for research, intervention programming, and classroom practice.     

Socio‐economic Status (SES) Affects Infants' Selective Exploration

Infants change their behaviours in accordance with the objects they are exploring. They also tailor their exploratory actions to the physical context. This selectivity of exploratory actions represents a foundational cognitive skill that underlies higher‐level cognitive processes. The present study compared the development of selective exploratory behaviours in high and low socio‐economic status (SES) infants. Sixty‐one 6–8‐ and 10–12‐month‐old infants were presented with rigid and flexible cubes on a tray that was half rigid and half flexible. There were SES effects for each category of exploratory behaviours: object only, surface only and object–surface interactions. Low‐SES infants engaged in comparable amounts of exploratory behaviours with high‐SES infants, but they exhibited behaviours less conducive to information uptake, compared with high‐SES infants. The results suggest difficulty for low‐SES infants in transitioning to more mature exploration strategies. Copyright © 2015 John Wiley & Sons, Ltd.     

Irrelevant‐action imitation is short‐term and contextual: Evidence from two under‐studied populations

Across the lifespan and across populations, humans ‘overimitate’ causally unnecessary behaviors. Such irrelevant‐action imitation facilitates faithful cultural transmission, but its immediate benefits to the imitator are controversial. Over short time scales, irrelevant‐action imitation may bootstrap artifact exploration or interpersonal affiliation, and over longer time scales it may facilitate acquisition of either causal models or social conventions. To investigate these putative functions, we recruited community samples from two under‐studied populations: Yasawa, Fiji, and Huatasani, Peru. We use a two‐action puzzle box: first after a video demonstration, and again one month later. Treating age as a continuous variable, we reveal divergent developmental trajectories across sites. Yasawans (44 adults, M = 39.9 years, 23 women; 42 children, M = 9.8 years, 26 girls) resemble documented patterns, with irrelevant‐action imitation increasing across childhood and plateauing in adulthood. In contrast, Huatasaneños (48 adults, M = 37.6 years, 33 women; 47 children, M = 9.3 years, 13 girls) evince a parabolic trajectory: adults at the site show the lowest irrelevant‐action imitation of any demographic set in our sample. In addition, all age sets in both populations reduce their irrelevant actions at Time 2, but do not reduce their relevant‐action imitation or goal attainment. Taken together, and considering the local cultural contexts, our results suggest that irrelevant‐action imitation serves a short‐term function and is sensitive to the social context of the demonstration.     

Strengthening socio‐emotional competencies in a school setting: Data from the Pyramid project

Background. Development of socio‐emotional competencies is key to children's successful social interaction at home and at school. Aims. This study examines the efficacy of a UK primary school‐based intervention, the Pyramid project, in strengthening children's socio‐emotional competencies. Sample. Participants were 385 children from seven schools in two UK cities. All children were aged 7–8 years and in school Year 3. Children were screened for socio‐emotional difficulties through the Strengths and Difficulties Questionnaire (SDQ; Goodman, 1997 ) and a multi‐agency meeting of relevant professionals before being allocated to attend a Pyramid Club intervention (n= 103) or a comparison group (n= 282). Method. A 2 × 2 mixed‐model design was used: group (intervention group vs. comparison group) × 2 time points (pre‐ vs. 12 weeks post‐intervention) with repeated measures on the time factor to investigate the impact of the Pyramid Year 3 intervention. Teachers completed the SDQ‐T4‐16 for all children pre‐ and post‐intervention to measure participants’ socio‐emotional health status. Results. As measured by the two SDQ difficulty sub‐scales of Emotional and Peer problems and the SDQ strength sub‐scale of Prosocial behaviour, post‐intervention improvements in the Pyramid attendee group were of greater magnitude than those of the comparison group. Conclusions. The Pyramid project intervention improves the socio‐emotional health of vulnerable children through promoting positive outcomes as well as reducing socio‐emotional deficits. These findings further support the inclusion of a salutogenic approach in promoting children's socio‐emotional well‐being.     

A comparison of dyadic interactions and coping with still‐face in healthy pre‐term and full‐term infants

Pre‐term birth has a significant impact on infants' social and emotional competence, however, little is known about regulatory processes in pre‐term mother‐infant dyads during normal or stressful interactions. The primary goals of this study were to investigate the differences in infant and caregiver interactive behaviour and dyadic coordination of clinically healthy pre‐term compared to full‐term infant‐mother dyads and to examine pre‐term infants' capacity for coping with stress using the face‐to‐face still‐face paradigm (FFSF). Fifty mother‐infant dyads, including 25 pre‐term infants and 25 full‐term infants were videotaped during the FFSF. All infants were 6–9 months of age (corrected for gestational age in the pre‐term group). Infant and maternal socio‐emotional expressivity and self‐regulatory behaviours were coded and measures of dyadic coordination (Matching, Reparation Rate, and Synchrony) were calculated. There were no significant differences in infant and caregiver socio‐emotional behaviours between the two groups and both groups demonstrated the still‐face (SF) effect and the reunion effect. There was a difference in self‐regulatory behaviour. Pre‐term infants were more likely than full‐term infants to use distancing (e.g., by turning away, twisting, or arching) from their mothers during the FFSF. Additionally, during the Reunion episode of the FFSF pre‐term infants showed more social monitoring compared to full‐term infants. Regardless of the birth status, the dyads showed less coordination and a slower rate of reparation during the Reunion episode than during the Play episode. The higher proportion of distancing in the pre‐term group and the increase in social monitoring suggest that even in normal interactions pre‐term infants may experience a higher level of stress and have less capacity for self‐regulation compared to the full‐terms and that pre‐term infants appear to use a compensatory strategy of increased social monitoring to cope with the stress of renegotiating the interaction during Reunion. The findings suggest that pre‐term infants have different regulatory and interactive capacities than full‐term infants.     

Enacting collective support for the European integration: Participation in pro‐integration action and preference for specific transnational acculturation strategies

We propose that collective support for European integration is mani‐fested in 2 distinct forms: first, as engagement in socio‐political action by citizens who seek to change their nation and its status in Europe. Second, it is manifested as a transnational acculturation process that impacts on both nations and their citizens. These processes potentially engage social identities at 3 levels: national, European and as supporters of the European integration. Here, we examine these different levels of identification as part of a model predicting collective support for the European integration. To capture the dimension of transnationality, we collected data from 2 Romanian samples, 1 of participants living in their country of origin (N = 203), and 1 of participants living as migrants outside Romania (N = 196). We found that identification as a pro‐integration supporter flows from European and Romanian national identifications and is an excellent predictor of collective support for European integration in both its forms. We conclude by discussing how our findings can be applied to the design of intervention strategies and policies to promote support for the European Union and the integration process in the current socio‐political climate (where the unity and the very existence of European Union are under threat).     

Physical home environment is associated with prefrontal cortical thickness in adolescents

Biologically embedded experiences alter developmental trajectories in ways that can influence health, learning, and/or behavior. These systematic differences in experiences may contribute to different biological outcomes as individuals grow and develop, including at the neural level. Previous studies of biologically embedded experiences on neurodevelopment have focused on large‐scale institutional or economic factors (e.g. socioeconomic status [SES]) and psychosocial factors (e.g. caregiving behavior). Less attention has focused on how the quality of the immediate home settings, such as the physical home environment (PHYS), influences neurodevelopment. Moreover, no study has investigated these effects in adolescents, who undergo significant physical maturation and neurodevelopment that may influence how they respond to their physical environments. The goal of the current study was to examine whether PHYS quality is biologically embedded in the developing adolescent brain as evidenced by cognitive achievement and cortical development in 56 (48% female) healthy adolescents (14–18 years (M = 16.83 years, SD = 1.17). Using in‐home assessments of the physical home environment, anatomical brain scans, and indices of academic achievement, we found that adolescents who have more physical problems in the home (e.g. structural hazards, crowding, excessive noise, poorly lit) have thinner prefrontal cortices, which was associated with lower levels of reading achievement, independent of SES and psychosocial factors. By conducting home visits to assess physical characteristics of adolescents’ home, we highlight a typically overlooked aspect of the home environment that has relevance for adolescents’ cognitive and brain development.     

Cortisol reactivity and negative affect among preterm infants at 12 months during a mother-infant interaction task

The purpose of this study was to investigate correlates of preterm (PT) infant’s cortisol reactivity and the association to infant negative affect, during a mother-infant interaction procedure. Participants included 48 infants born prematurely (gestational age < 37 weeks) and their mothers, assessed when infants were 12 months old corrected for prematurity. The examined variables comprised both neonatal and environmental dimensions including maternal interactive behavior. Infant negative affect and maternal interactive behavior were assessed with a standardized mother-infant interaction task. A baseline infant saliva sample was collected before the interaction began, and a second sample after the interaction episodes ended. Results revealed that decrease of infant’s cortisol concentration was significantly associated with the exposure to more sensitive, and less intrusive maternal behaviors. However, once controlled for neonatal risk, family SES and maternal psychological distress, the associations were rendered non-significant. Although the association between cortisol reactivity and negative affect trended toward significance, maternal intrusiveness was the only significant predictor of observed infant negative affect. Findings suggest the importance of primary relational experiences on PT infants' early regulatory competencies.     

Selective and faithful imitation at 12 and 15 months

Research on imitation in infancy has primarily focused on what and when infants imitate. More recently, however, the question why infants imitate has received renewed attention, partly motivated by the finding that infants sometimes selectively imitate the actions of others and sometimes faithfully imitate, or overimitate, the actions of others. The present study evaluates the hypothesis that this varying imitative behavior is related to infants' social traits. To do so, we assessed faithful and selective imitation longitudinally at 12 and 15 months, and extraversion at 15 months. At both ages, selective imitation was dependent on the causal structure of the act. From 12 to 15 months, selective imitation decreased while faithful imitation increased. Furthermore, infants high in extraversion were more faithful imitators than infants low in extraversion. These results demonstrate that the onset of faithful imitation is earlier than previously thought, but later than the onset of selective imitation. The observed relation between extraversion and faithful imitation supports the hypothesis that faithful imitation is driven by the social motivations of the infant. We call this relation the King Louie Effect: like the orangutan King Louie in The Jungle Book, infants imitate faithfully due to a growing interest in the interpersonal nature of interactions.
