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 depression and the timing of mother–child dialogue

Turn-taking in dialogue is an essential part of communication and early language experience. The prevalence of utterances and the timing of responses in dialogue were examined at 14 and 36 months of age in 104 mother–child dyads from the Early Head Start Research and Evaluation Project (EHSREP). Mothers varied in their level of depression risk (measured with the Center for Epidemiological Studies-Depression scale; CES-D). Although maternal utterance rate did not vary significantly across any factors, the latency of mothers' responses to their children decreased with development (12 ms/month) and was significantly related to that of their own children (i.e., slow-responding children had slow-responding mothers). Mothers with higher levels of depressive symptoms were 11% slower in responding to their children than mothers with low depression risk, suggesting that the interactive timing of speech to children may be particularly sensitive to maternal depression, modifying the contingent properties of children's early language experience.     

The importance of maternal state of mind regarding attachment and infant age at placement to foster mothers' representations of their foster infants

Previous research has found that foster mother state of mind with respect to attachment and infant age at placement into foster care influence the developing foster mother–foster child relationship (Dozier, Albus, Stovall, & Bates, 2000; Stovall & Dozier, 2000). This study extends prior research by assessing factors related to foster mothers' representations of their foster infants. Participants were 48 foster mother–foster infant dyads in two mid‐Atlantic cities. We expected that foster mothers' states of mind and infant age at placement would be associated with foster mothers' acceptance of infants, commitment to infants, and belief in their influence on infants' development. Consistent with hypotheses, foster mothers' states of mind interacted with infant age at placement in predicting foster mothers' acceptance of their babies, and the extent to which foster mothers believed they could influence their infants' development. Specifically, autonomous foster mothers of babies placed before 12 months of age were more accepting and more likely to believe they could influence their infants' development compared to autonomous foster mothers of babies placed after 12 months of age, a pattern not seen for nonautonomous foster mothers. These results converge with other findings suggesting that timing of placement in foster care, and foster mothers' states of mind, are important to the developing foster mother–child relationship. ©2002 Michigan Association for Infant Mental Health.     

Étude du style interactif maternel et des compétences sociocommunicatives des enfants. Une étude comparative entre enfants porteurs de trisomie et enfants typiques

The goal is to explain Down syndrome social language disturbances. Down's syndrome and non-handicapped children were observed interacting with their mothers. We compared 22 dyads with Down syndrome children and 22 dyads with non-handicapped children. Down's syndrome children were matched on mental age with non-handicapped children (4 to 24 months). Social context, mothers' behaviours and children's social communicative competences were evaluated. Interaction behaviours in the mothers of DS children differ from those of mothers of non-handicapped children. DS communicative competences also are different from those in non-handicapped children. We argue that mothers' behavioural interaction in the dyads with DS children can be an aspect of social communicative disturbances of DS children.     

The co‐construction of joint action between mothers and 2–4‐month‐old infants: the mother's role

The purpose of this longitudinal study was to describe object‐centred interactions between mothers and their 2–4‐month‐old infants, before and during the emergence of reaching and grasping movements. We hypothesized that when reaching movements emerge at around 3 months, mothers alternate between attention stimulation and reaching stimulation, before joint actions between mother and infant develop around objects. Twelve dyads were recorded when infants were 2 months, 3 months and 4 months. The interactive sessions lasted 5 min. Three age‐appropriate toys the infant could handle were available to the mother. A principal component analysis (PCA) was performed on verbal and non‐verbal maternal behaviours, motor infant behaviours and co‐occurrences of those behaviours. The developmental course of prehension in infants when playing with their mother follows similar pathways, as was described when they are observed alone. Mothers appeared to early scaffold prehension skills by verbal and non‐verbal means. Moreover, maternal behaviours change according to the infant's behaviour, and conversely, infant's behaviours influence maternal behaviours: mother plays first an active part in joint action, while later on, the infant achieves joint action when motor skills develop.

Play and emotional availability in young children with Down syndrome

This study investigates mother–child interaction and its associations with play in children with Down syndrome (DS). There is consensus that mother–child interaction during play represents an important determinant of typical children's play development. Concerning children with DS, few studies have investigated mother–child interaction in terms of the overall emotional quality of dyadic interaction and its effect on child play. A sample of 28 children with DS (M age = 3 years) took part in this study. In particular, we studied whether the presence of the mother in an interactional context affects the exploratory and symbolic play of children with DS and the interrelation between children's level of play and dyadic emotional availability. Children showed significantly more exploratory play during collaborative play with mothers than during solitary play. However, the maternal effect on child symbolic play was higher in children of highly sensitive mothers relative to children whose mothers showed lower sensitivity, the former displaying more symbolic play than the latter in collaborative play. Results offer some evidence that dyadic emotional availability and child play level are associated in children with DS, consistent with the hypothesis that dyadic interactions based on a healthy level of emotional involvement may lead to enhanced cognitive functioning.     

Assessing the impact of a family nurse-led intervention on young mothers’ references to internal states

A mother's propensity to refer to internal states during mother–child interactions is important for her child's developing social understanding. However, adolescent mothers are less likely to reference internal states when interacting with their children. We investigated whether young mothers’ references to internal states are promoted by the Family Nurse Partnership (FNP) intervention, an intensive home-visiting programme designed to support adolescent mothers in England. We also investigated family, maternal, and child factors associated with young mothers’ references to inner states during interactions with their children. Adolescent mothers (n = 483, aged ≤ 19 years when recruited in pregnancy) and their children participated in an observational substudy of a randomized controlled trial investigating the impact of FNP compared to usual care. Mother–child dyads were video-recorded during free play, and mothers’ speech was coded for use of internal state language (references to cognitions, desires, emotions, intentions, preferences, physiology, and perception). We found no differences in mothers’ use of internal state language between the FNP and usual care groups. A sample-wide investigation identified that other features of mothers’ language and relationship status with the child's father were associated with internal state language use. Findings are discussed with reference to targeted interventions and implications for future research.     

Dyadic co-regulation,affective intensity and infant's development at 12 months: A comparison among extremely preterm and full-term dyads

Extremely low gestational age children (ELGA, born below 28 weeks of GA) represent the most at-risk preterm group in terms of survival, developmental sequelae and rates of impairment and cognitive delays. However, the impact of an extremely preterm birth on mother–infant co-regulation and affective intensity which may affect early infant's development has not been investigated. Based on a relational dynamic system approach, our study aimed to investigate the quality of co-regulation and affective intensity during spontaneous play interaction in 20 mother–infant ELGA dyads compared to 20 full-term (FT) dyads at 12 months (corrected age for ELGA infants). Relationships between the quality of dyadic co-regulation and the infant's level of cognitive, motor and language development were also investigated. The quality of dyadic co-regulation was assessed using the Revised Relational Coding System (R-RCS) by Fogel et al. (2003), the mothers’ and infants’ affective intensity was coded using a coding system by Lunkenheimer, Olson, Hollenstein, Sameroff, and Winter (2011). Infants’ development was assessed using the Bayley Scales (BSID-III, 2006). With respect to FT dyads, ELGA dyads were characterised by less frequent symmetric and more frequent unilateral co-regulation patterns and by less positive and more neutral affective intensity of both infants and mothers. Cognitive, motor and language scores were lower in ELGA infants than in FT infants. Symmetrical co-regulation was related to motor scores in ELGA infants, and to cognitive scores in FT infants. Our findings contribute to the literature by demonstrating the difficulties of ELGA mother–infant dyads at 12 months in sharing the symmetric co-regulation and positive affective intensity and how symmetric co-regulation is strictly related to motor development in ELGA infants. Based on these findings, intervention programmes to foster joint attention, active involvement and positive affective intensity in ELGA dyads and infants’ development in the first year of life should be designed.     

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.     

Evolutionary roots of intuitive parenting: Maternal competence in chimpanzees

Intuitive parenting behaviours have been shown to be universal in humans and appear to be based on psychobiological preadaptedness. This study is an exploration of the evolutionary roots of intuitive parenting through naturalistic observation of mother chimpanzees' interaction with their very young infants. Maternal competence is demonstrated initially through the behaviours of carrying the newborn infant and allowing the infant to nurse. Very early mother–infant interactions include play, ‘exercise’, cradling and grooming. Chimpanzee mothers also assess their offspring's behavioural state and muscle tone through visual inspections and movement of legs, arms, fingers and toes. Chimpanzee mothers and infants, as early as 2 weeks of age, spend some time in mutual gaze. Neonatal chimpanzees are capable of sustained face-to-face interactions, as these were observed in nursery-reared chimpanzee interactions with human adults; however, it appears that chimpanzee mothers encourage mutual gaze with their infants for only brief durations. Chimpanzees with good maternal competence exhibit sensitive responsivity to infants' communicatory signals. Thus the results of this study support the claim that there are evolutionary and comparative foundations of intuitive parenting evident in the maternal behaviour and maternal competence of chimpanzees.     

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.     

Maternal representations and emotional availability among drug‐abusing and nonusing mothers and their infants

Both negative and idealized maternal prenatal representations may constitute a risk for mother–infant interaction. This study analyzed the role of maternal prenatal representations and pre‐ to postnatal representational change in predicting mother–infant emotional availability (EA) among 51 drug‐abusing mothers and their infants who participated in either psychodynamic group therapy (PGT) or received psychosocial support (PSS) and among 50 nonusing comparison dyads. Maternal representations of her child, the child's father, her own mother, self‐as‐mother, and self‐as‐woman were measured during pregnancy and at 4 and 12 months' postpartum with the Interview of Maternal Representations (M. Ammaniti et al., 1992 ; M. Ammaniti, R. Tambelli, & P. Perucchini, 1998). EA was measured with the Emotional Availability Scales, fourth edition (Z. Biringen, 2008 ) at 4 and 12 months. The results showed that drug‐abusing mothers had more negative prenatal representations of the self‐as‐woman and of the child's father. Postnatally, PSS mothers tended to first idealize their child, but later to experience disillusionment of idealization. Both negative and idealized prenatal representations of the self‐as‐mother predicted mother–infant EA problems, but only among the PGT mothers. For all mothers, negative representational change was detrimental for the mother–infant EA whereas for drug‐abusing mothers, also increasing idealization from the prenatal period to the postnatal period was harmful. Clinicians working with drug‐abusing mothers should aim at supporting the development of a realistically positive view of motherhood.     

Defence strategies and anxiety in mothers of disabled children

The aim of this investigation was to study anxiety and defence strategies in mothers of children with different disabilities. Mothers of children with childhood psychosis, motor handicaps, or Down's syndrome were tested with a projective, percept-genetic technique, viz. the Mother-Child Picture Test (MCPT). Levels of anxiety were measured with the Hospital Anxiety and Depression Scale (HAD). In mothers of psychotic children, the absence of anxiety was significantly associated with misinterpretations and/or failure to recognize the MCPT motif (a close relation between mother and child). This association was not found in the mothers of motor-handicapped children or children with Down's syndrome. The results suggest that, for mothers of psychotic children, the activation of defensive strategies is important to avoid feelings of anxiety evoked by the mother-child situation. For mothers of children with other chronic disabilities, for example, motor handicaps or Down's syndrome, low levels of anxiety may be experienced without the mobilization of strong defensive mechanisms. Different interpretations of the correlation between defence strategies and anxiety in the mothers of psychotic children are discussed.     

Cross-sectional study of coordination between infants' gaze and vocalizations towards their mothers

The study aimed at providing more precise information about infants' capacity to coordinate their vocalizations with gaze towards their mothers. A total of 32 infants were observed, four boys and four girls in each of four age groups (4, 6, 8 and 10 months), in an observational setting aimed at minimizing infants' casual looks to their mothers. Videotapes of mother-infant-toy interactions were coded separately for infants' vocalizations and gaze towards their mothers, and the difference between observed and expected cooccurrence of these two communicative behaviours was evaluated by transfromation into z-scores. Results indicate that only at 10 months of age do infants develop the ability to coordinate vocalizations and gazes towards mother. Moreover, more competent subjects show temporal relationships between gaze and vocalizations different from those observed in less competent subjects.     

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.     

Maternal conceptions of the parenting role and mother–child collaborative behaviours in at-risk context

This study investigated to what extent mothers' conceptions of the parenting role drive mother–child collaborative behaviour as well as expert ratings on maternal practices. It also investigated whether there is any direct link between mother and child behaviours and expert ratings. Self-report measures for maternal conceptions and observed mother–child behaviours in the shopping task were obtained from a sample of 75 at-risk mothers with a child 8 to 12 years old. Social workers reported on mothers' negligent, coercive and resilient practices. Structural equation models showed that high power conception had a negative influence on mother and child's collaborative efforts, whereas reciprocity and parental support conceptions had a positive influence. Reciprocity, low power and parental support schemas consistently predicted experts' view on maternal practices. However, only mother's passivity predicted negatively expert ratings on resilient practice, indicating that expert views were mostly derived from mothers' reflections on their parenting role. Results suggested ways for improving experts' assessment of parental capacities and the use of intervention programmes to promote mothers' positive conceptions and actions.     

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–Toddler Affect Exchanges and Children's Mastery Behaviours during Preschool Years

This study examined the longitudinal relations of mother–child affect exchanges at 18 months with children's mastery motivation at 39 months. Observation and questionnaire data were collected from mother–child dyads when children were 18 months; 43 mothers again rated their children's mastery motivation at 39 months. Results suggested that after controlling for gender and the corresponding 18‐month mastery aspect, positive affect exchanges had long‐term positive relationships with children's persistence and competence, whereas dismissed affect exchanges had long‐term negative relationships with children's persistence and independent mastery. Findings suggest that children's autonomous mastery‐oriented endeavours have deep roots in their early mother–child affective interactions. Copyright © 2013 John Wiley & Sons, Ltd.     

Patterns of Attachment in Frequently and Infrequently Reading Mother—Child Dyads

This study explored the relationship between the quality of the mother–child attachment and how often mothers read to their children. Eighteen children who were read to infrequently were matched to a group of children who were read to daily, for sex, age, and socioeconomic status. The children's mothers read them a booklet, mother and child were observed in a reunion episode, the children completed the Peabody Picture Vocabulary Test (Dunn, 1965) and Frostig's (1966) test for spatial orientation, and the mothers were given the Adult Attachment Interview (George, Kaplan, & Main, 1984). The mothers in the frequently reading dyads did not need to discipline their child to focus on the reading task as often as the mothers in the infrequently reading dyads did. Mothers whose attachment to their child was less secure spent less time reading to their child and had more troublesome episodes during the reading session than mothers whose attachment to their child was more secure. The security of the mother-child attachment was related to the mothers' representation of their relationship with their parents, and mothers who had a secure relationship with their child read more frequently to their child than did mothers who had an insecure relationship with their child.     

Observer Influences on Fathers and Mothers: An Experimental Manipulation of the Structure and Function of Parent – Infant Conversation

From studies over the past 20 years four contrasting hypotheses can be made about the nature of parent–infant communication: (1) mothers and fathers display similar skills to their infants and do not exert a differential influence on their development; (2) fathers are less sympathetic to their infants' level of development and therefore inadvertently stretch the child's development more than mothers; (3) both parents differentially socialize their sons' and daughters' early communicative skills; (4) any apparent differences between parents reflect their expectations about being observed. To examine these hypotheses together, this experiment records the communication of 10 mother–infant and 10 father–infant dyads in two conditions: when an observer was present or absent. The analysis revealed two patterns. Firstly, in keeping with most research on parent–child communication, mothers and fathers both simplified their speech to their infants in similar ways. Secondly, both the structure and function of parental communication showed differences between the two conditions and many of these differences were moderated by interactions between condition and sex of parent or child. The data thus provide more support for the first and fourth hypotheses cited above. It is suggested that analyses of parent–infant interaction should move away from simple assumptions about parental ‘influences’ upon children's development to consider the subtleties of different parental styles in different settings.
