Social pretence with mothers and peers at 15 months

Previous research has shown that adults scaffold and direct early infant social pretend play making it difficult to establish infants' own contribution to pretence. To examine infants' social pretence abilities the present study compared infants' social pretend play in interactions with adults and same-age peers, who have similar socio-cognitive competence. Forty-five 15-month-old infants were observed during free-play interactions with their mother and two same-age, same-gender peers. The frequency and duration of parallel and coordinated social pretence were coded during both interactions. Results showed that while infants played pretence with both social partners, they engaged in more and longer coordinated social pretence with their mothers than with peers. Thus, although competent social partners play an important role in scaffolding complex pretence, infants' own socio-cognitive abilities contribute to the development of social pretence and enable them to pretend play with different partners regardless of their competencies.     

Comparing emotional coordination in early spontaneous mother–infant and father–infant interactions

We compare matching of facial expressions and attunement of emotional intensity in spontaneous communication of mothers with infants and of fathers with infants, in families in Crete. Eleven infant–mother and 11 infant–father dyads were video-recorded at home in familiar interactions from the 2nd to the 6th month. Microanalysis of infant, maternal and paternal facial expressions of emotion provided evidence of quantitative differences that favour father–infant interaction as more playful, but the infants' behaviours with mothers and fathers show similar developmental curves. These results are discussed in the frame of the theory of innate intersubjectivity and of the emotional support parents give to developing motives of infants.     

Development of mother–infant interaction in tickling play: The relationship between infants’ ticklishness and social behaviors

This study examined the development of mother–infant tickling interaction and the relationship between infants’ ticklishness and social behaviors including infants’ looking at mothers’ face, mothers’ narrative tickling, and mothers’ laughter. Twenty-two Japanese infants aged 5 months (n = 10, five girls) and 7 months (n = 12, four girls) and their mothers were videotaped. Results revealed that the mothers’ narrative tickling was more frequent at 7 than at 5 months and the infants’ strong ticklishness showed the same tendency. The infants’ strong ticklishness was linked with the occurrence of other social behaviors. In conclusion, infants’ ticklishness was heavily connected with social behaviors. The mode of the tickling interaction at 7 months was different from that at 5 months especially in the increase of mother’s narrative tickling. A possible function of such mother’s narrative tickling to facilitate infant active communication at a higher cognitive level including anticipation, was discussed.     

Patterns of mother–infant interaction from 3 to 12 months among dyads with substance abuse and psychiatric problems

The aim of this study was to investigate the development of mother–infant interaction patterns from 3 to 12 months among three groups of mother–baby pairs recruited during pregnancy: one group from residential substance abuse treatment (n = 28), a second group from psychiatric outpatient treatment (n = 22), and a third group from well-baby clinics (n = 30). The mother–infant interaction at 3 and 12 months was assessed by the Parent–Child Early Relational Assessment (PCERA), which consists of maternal, child and dyadic subscales (Clark, 2006). Linear mixed effects models were used to analyze group differences and the changes in mother–infant interaction from 3 to 12 months.At 3 months, pairwise comparisons showed that the group with psychiatric problems had significantly more difficulties in the mother–infant interaction than the two other groups. The group with substance abuse problems was not significantly different from the two other groups. At 12 months, the mother–infant pairs in the substance abuse group showed significantly more relational disturbances than the non-clinical pairs, as well as a poorer affective quality of interaction than the dyads in the group with psychiatric problems. Analysis of change from 3 to 12 months showed that difficulties in the interaction increased among the mother–baby pairs in the substance abuse group, while improvements were displayed in the two other groups. These results underline that mother–infant pairs at double risk due to maternal substance abuse and other non-optimal factors, are in need for long-term follow up in order to prevent the development of negative interactional patterns.     

Peek-a-who? Exploring the dynamics of early communication with an interactive partner swap paradigm and state space grid visualization

Effective caregiver-infant communication occurs when interactive partners successfully coordinate multiple modalities (e.g., body movements, affect, eye gaze). The complex interplay of multiple modalities during caregiver-infant interactions is difficult to capture, which has made a comprehensive, evidence-based understanding of caregiver-infant communication difficult to achieve. We present a novel methodological approach to address this challenge by combining an Interactive Partner Swap (IPS) paradigm with a longitudinal design, detailed multimodal coding, and data visualization via state space grids (SSGs). We demonstrate the utility of our approach by presenting three sets of SSGs which reveal both dyadic flexibility and stability in caregiver-infant peek-a-boo interactions across three levels: micro (moment-to-moment), meso (interactive context), and macro (infant development). By using SSGs to explore the patterns that hold and others that differ systematically across interactive partner and infant development, our novel approach promises to offer critical first steps to creating a more detailed understanding of the dynamics of early multimodal communication.     

Effects of an early intervention on maternal post-traumatic stress symptoms and the quality of mother–infant interaction: The case of preterm birth

Preterm birth may represent a traumatic situation for both parents and a stressful situation for the infant, potentially leading to difficulties in mother–infant relationships. This study aimed to investigate the impact of an early intervention on maternal posttraumatic stress symptoms, and on the quality of mother–infant interactions, in a sample of very preterm infants and their mothers. Half of the very preterm infants involved in the study (n = 26) were randomly assigned to a 3-step early intervention program (at 33 and 42 weeks after conception and at 4 months’ corrected age). Both groups of preterm infants (with and without intervention) were compared to a group of full-term infants. The impact of the intervention on maternal posttraumatic stress symptoms was assessed 42 weeks after conception and when the infants were 4 and 12 months of age. The impact of the intervention on the quality of mother–infant interactions was assessed when the infants were 4 months old. Results showed a lowering of mothers’ posttraumatic stress symptoms between 42 weeks and 12 months in the group of preterm infants who received the intervention. Moreover, an enhancement in maternal sensitivity and infant cooperation during interactions was found at 4 months in the group with intervention. In the case of a preterm birth, an early intervention aimed at enhancing the quality of the mother–infant relationship can help to alleviate maternal post-traumatic stress symptoms and may have a positive impact on the quality of mother–infant interactions.     

The development of Japanese mother–infant feeding interactions during the weaning period

During the weaning period, infants are not skilled at self-feeding and caregivers play a prominent role in feeding. Solid feeding is therefore an inherently collaborative and interactive process between infants and caregivers. The present study examined how caregivers and infants coordinate their solid feeding interactions, based on naturalistic longitudinal observations of three Japanese mother–infant dyads. The main results were as follows. Four or five months after weaning (about 10–11 months of age), children's mouth movements and mothers’ arm movements became more synchronized, and the success or failure of coordinated feeding became independent on children's gaze behavior. During this same period, both mothers’ and children's body movements accelerated. Specifically, children's food-intake motions and mothers’ food-carrying movements became faster together, although before 10–11 months fluctuations of these motions were not as correlated. Finally, at 9–11 months of age rhythmic body movements became frequent. From the first day of weaning, all three mothers swayed their bodies rhythmically while feeding, and about 2–3 months later their children also began to sway as they ate, at first infectiously but later spontaneously. These observations indicate how specific behavioral development contributes to mother–infant coordination in feeding.     

Maternal perinatal representations and their associations with mother–infant interaction and attachment: A longitudinal comparison of Portuguese and Brazilian dyads

Prior research in Western countries (mostly the US, Canada and northern Europe) indicates that mothers' representations are associated with mother–infant interaction quality and their child's attachment security later in the first year. Fewer studies, however, have evaluated whether these associations hold for mother–infant dyads in other countries, such as Brazil and Portugal. Although these countries share a similar language and culture, they differ on societal dimensions that may affect parenting attitudes and mother–infant relationships, such as economic stress, social organisation, social policy, and the availability of services for young families. In this longitudinal study, we followed two independent samples of Brazilian and Portuguese mother–infant dyads from the perinatal period to 12 months post-partum. We assessed mothers' perinatal representations using semi-structured interviews in the first 48 hours after the infant's birth, and evaluated the associations of these representations with mother interaction quality at 9 months and infant attachment at 12 months. Results were similar in each country, corroborating prior research in single Western countries: Mothers with more positive perinatal representations were more sensitive to their infants during free play at 9 months and were more likely to have infants classified as securely attached at 12 months.     

Mother–infant interactions with firstborns and secondborns: A within-family study of European Americans

Given the large numbers of families with more than one child, understanding similarities and differences in siblings’ behaviors and in parents’ interactions with their sibling infants is an important goal for advancing more representative developmental science. This study employed a within-family design to examine mean-level consistency and individual-order agreement in 5-month-old sibling behaviors and maternal parenting practices with their firstborns and secondborns (ns = 61 mothers and 122 infants). Each infant was seen independently with mother. Firstborn infants were more social with their mothers and engaged in more exploration with objects than secondborn infants; firstborn and secondborn infants’ behaviors were correlated for smiling, distress communication, and efficiency of exploration. Mothers engaged in more physical encouragement, social exchange, didactic interaction, material provisioning, and language with their firstborns than with their secondborns. Notably, only maternal nurturing (e.g., feeding, holding) did not differ in mean level when mothers were with their two infants. However, mean differences in mothers’ social exchange and material provisioning with their two children attenuated to nonsignificance when controlling for differences in siblings’ behaviors. Individual-order agreement of mothers’ behaviors with firstborn and secondborn infants (across an average of almost 3 years) was only moderate. These findings suggest that mother–firstborn interactions may differ from mother–secondborn interactions. Future research should move beyond studying mother–firstborn dyads to understand broader family and developmental processes.     

A categorical approach to infants’ individual differences during the Still-Face paradigm

Cluster analysis was used to create patterns of individual differences reflecting infant behaviors during the initial interaction episode of the Face-to-Face Still-Face (FFSF) paradigm. The clusters were used as the basic unit of analysis for studying infant and maternal behavior and dyadic coordination (i.e., matching and reparation) across FFSF. Seventy-five 4-month-old infants participated with their mothers. Cluster analysis identified three patterns: a Socially Engaged cluster (33%) exhibited high levels of social engagement with their mothers; a Disengaged cluster (60%) showed a tendency to be low in social interaction and a Negatively Engaged cluster (7%) showed high negative emotionality. During the Still-Face episode, the Socially Engaged cluster reacted by reducing focus on their mother and shifting their attention elsewhere, while infants in the Disengaged cluster reduced focus on the environment. Although both the Socially Engaged and Disengaged clusters increased in negative emotionality during the Still-Face, the Socially Engaged group largely recovered during the Reunion, whereas the Disengaged group displayed more negative emotion. The Negatively Engaged cluster demonstrated high levels of negative affect throughout the entire procedure. Mothers of Negatively Engaged infants showed less positive engagement and more social monitoring than mothers in other clusters during all episodes. Dyadic interaction differed between groups, with greater levels of matching and reparations in the engaged group, less in the Disengaged group, and very little coordination in the Negatively Engaged cluster. Findings highlight the role of distinctive patterns of infants’ individual differences in determining early dyadic functioning.     

Antenatal and postnatal depressive symptoms: Association with quality of mother–infant interaction

Antenatal and postnatal depression are independently associated with an increased risk of adverse infant development. A key linking mechanism is the quality of mother–infant interaction.ObjectivesThis study assesses the association between postnatal depressive symptoms (PDS) and their severity, with the quality of mother–infant interaction and compare the quality of mother–infant interaction and severity of the symptoms depending on the presence or absence of antenatal depressive symptoms (ADS).Methodsobservational study in 177 psychosocial risk mother–infant dyads from Chile (infant aged 2–12 months).ResultsMothers with PDS had lower maternal sensitivity and a more intrusive/controlling style than mothers without PDS, although the severity of the symptoms was not associated with lower maternal sensitivity. Maternal sensitivity did not differ in the postnatal depressed mothers depending on the presence of ADS, although the mothers differed in interaction style and the severity of symptoms. Mothers with ADS and PDS presented with a predominant intrusive/controlling interaction style and more severe depressive symptoms, whereas those with only PDS presented with a predominant nonresponsive/passive interaction style and reduced severity of symptoms.ConclusionsThe results corroborate the need to offer treatment and dyadic interventions to antenatal and postnatal depressive mothers and postulate that the presence of antenatal depressive symptoms may influence the subsequent mother–infant interaction style and greater severity of symptoms.     

The many faces of the Still-Face Paradigm: A review and meta-analysis

The Still-Face Paradigm (SFP) designed by Tronick, Als, Adamson, Wise, and Brazelton (Tronick, E., Als, H., Adamson, L., Wise, S., & Brazelton, T. B. (1978). Infants response to entrapment between contradictory messages in face-to-face interaction. Journal of the American Academy of Child and Adolescent Psychiatry, 17, 1–13) has been used for many different purposes in over 80 empirical studies. In the current paper, the nature and correlates of infant behavior in the SFP were examined in a systematic narrative review and a series of meta-analyses. The results of the meta-analyses confirmed the classic still-face effect of reduced positive affect and gaze, and increased negative affect, as well as a partial carry-over effect into the reunion episode consisting of lower positive and higher negative affect compared to baseline. The still-face effect is very robust as it was found regardless of most sample variations such as infant gender and risk status, and regardless of most procedural variations, such as the length of the SFP episodes and the use of intervals between episodes. The few moderator effects that were found in the meta-analyses tended to put findings from the narrative review in a new perspective. Additional meta-analyses confirmed the narrative review in finding that higher maternal sensitivity predicted more infant positive affect during the still-face. Infants’ higher positive affect and lower negative affect during the still-face were predictive of secure attachment at age 1 year. The meta-analytic results for maternal depression were equivocal. Implications for future research include a need for studies testing the role of the adults’ identity (parent versus stranger, mother versus father) to elucidate the relationship-specificity of the still-face effect. Also, the role of maternal sensitivity and temperament as potential moderators of the still-face effect need to be examined further. On a procedural level, the effects of the timing of the still-face and of the duration of the reunion on infant responses deserve future research attention.     

Mothers who are securely attached in pregnancy show more attuned infant mirroring 7 months postpartum

This study contrasted two forms of mother–infant mirroring: the mother's imitation of the infant's facial, gestural, or vocal behavior (i.e., “direct mirroring”) and the mother's ostensive verbalization of the infant's internal state, marked as distinct from the infant's own experience (i.e., “intention mirroring”). Fifty mothers completed the Adult Attachment Interview (Dynamic Maturational Model) during the third trimester of pregnancy. Mothers returned with their infants 7 months postpartum and completed a modified still-face procedure. While direct mirroring did not distinguish between secure and insecure/dismissing mothers, secure mothers were observed to engage in intention mirroring more than twice as frequently as did insecure/dismissing mothers. Infants of the two mother groups also demonstrated differences, with infants of secure mothers directing their attention toward their mothers at a higher frequency than did infants of insecure/dismissing mothers. The findings underscore marked and ostensive verbalization as a distinguishing feature of secure mothers’ well-attuned, affect-mirroring communication with their infants.     

Social interaction facilitates word learning in preverbal infants: Word–object mapping and word segmentation

In natural settings, infants learn spoken language with the aid of a caregiver who explicitly provides social signals. Although previous studies have demonstrated that young infants are sensitive to these signals that facilitate language development, the impact of real-life interactions on early word segmentation and word–object mapping remains elusive. We tested whether infants aged 5–6 months and 9–10 months could segment a word from continuous speech and acquire a word–object relation in an ecologically valid setting. In Experiment 1, infants were exposed to a live tutor, while in Experiment 2, another group of infants were exposed to a televised tutor. Results indicate that both younger and older infants were capable of segmenting a word and learning a word–object association only when the stimuli were derived from a live tutor in a natural manner, suggesting that real-life interaction enhances the learning of spoken words in preverbal infants.     

Linguistic and prosodic aspects of child-directed speech: The role of maternal child-rearing experiences

This study explored if the quality of mothers’ reported child-rearing experiences influences the prosodic and linguistic features of maternal child-directed speech. Lexical, syntactic, functional and prosodic aspects of maternal speech directed towards their 24-month-old children were examined. Results showed that mothers with different child-rearing histories differed in the ways they talked to their children. Mothers who recalled the caregiving they received during childhood as characterized by high levels of care and low levels of control, used a lexically and syntactically more complex speech and expressed more positive emotions. This kind of input seems to be more attuned with the typical growing skills of two-year-old children. Implications for the study of mother–infant relationship as well as for the study of child language development are addressed.     

Mother–infant mutual eye gaze supports emotion regulation in infancy during the Still-Face paradigm

This study was designed to examine the sequential relationship between mother–infant synchrony and infant affect using multilevel modeling during the Still Face paradigm. We also examined self-regulatory behaviors that infants use during the Still-Face paradigm to modulate their affect, particularly during stressors where their mothers are not available to help them co-regulate. There were 84 mother–infant dyads, of healthy full term 4 month old infants. Second-by-second coding of infant self-regulation and infant affect was done, in addition to mother–infant mutual eye gaze. Using multilevel modeling, we found that infant affect became more positive when mutual gaze had occurred the previous second, suggesting that the experience of synchronicity was associated with observable shifts in affect. We also found a positive association between self-regulatory behaviors and increases in positive affect only during the Still-Face episode (episode 2). Our study provides support for the role of mother–infant synchronicity in emotion regulation as well as support for the role of self-regulatory behaviors in emotion regulation that can have important implication for intervention.     

Social dynamics in the preschool

In this paper, we consider how concepts from dynamic systems (such as attractors, repellors, and self-organization) can be applied to the study of young children’s peer relationships. We also consider how these concepts can be used to explore basic issues involving early peer processes. We use the dynamical systems approach called state space grid (SSG) analysis and consider how it can be expanded beyond the study of dyads to the study of larger social groups and networks. In particular, we explore the role of homophily—that is, behavioral and sex similarity—as factors in the self-organization of young children’s social groups. A dynamic systems approach allows for consideration of peer processes difficult to assess using more traditional approaches.
