Maternal correlates of infant temperament ratings and of infant-mother attachment: A longitudinal study

This study examined longitudinally correlates of mothers' ratings of their infant's temperament and of the infant-mother attachment relationship. Measures included Carey's Revised Infant Temperament Questionnaire, child-rearing attitudes, psychophysiological responses to an unfamiliar infant's crying pre- and postdelivery, psychophysiological responses to the mother's own infant's crying, and assessments of infant-mother attachment. The results indicated that maternal ratings of infant temperament at 4 months were significantly related not only to concurrent cry responsiveness but also to cry responsiveness and child-rearing attitudes predelivery, as well as to the quality of attachment at 1 year. It is suggested that a differential response pattern of mothers of “easy” and of “difficult” infants, which affects the developing infant-mother bond, may in part originate in maternal dispositions existing prior to parenthood.     

Stability of maternal postnatal bonding between 3 and 6 months: Associations with maternal mental health and infant temperament

Maternal bonding is key for infant development and well-being. Research to date focused on prenatal bonding experience, with fewer studies looking at the postnatal period. Moreover, evidence suggests significant associations among maternal bonding, maternal mental health, and infant temperament. The joint impact of maternal mental health and infant temperament on maternal postnatal bonding remains unclear, with limited research reporting longitudinal data. Hence, the present study aims (1) to explore the impact of maternal mental health and infant temperament on postnatal bonding at both 3 and 6 months of age, (2) to explore postnatal bonding stability from 3 to 6 months, and (3) to determine which factors are linked with 3-to-6-month changes in bonding. At the infants' 3 months (n = 261) and 6 months of age (n = 217), mothers provided measures of bonding, depressive and anxious symptoms, and infant temperament via validated questionnaires. At 3 months, higher levels of maternal bonding were predicted by lower levels of anxiety and depression in the mothers and by higher infants' regulation scores. At 6 months, lower levels of anxiety and depression predicted higher levels of bonding. Moreover, mothers showing decreases in bonding were characterized by 3-to-6-month increases in depression and anxiety, as well as increased reported difficulties in regulation dimensions of infant temperament. This study highlights the impact of both maternal mental health and infant temperament on maternal postnatal bonding in a longitudinal sample and could offer useful information for early childhood prevention and care.     

Synchrony in the Triad: A Microlevel Process Model of Coparenting and Parent‐Child Interactions

Guided by a microanalytic approach to the study of relationships, we assessed parent, infant, and coparental behaviors during triadic interactions in 94 parents and their 5‐month‐old firstborn child. Relational behaviors in each family subsystem—mother‐infant, father‐infant, and coparenting—were microcoded. Marital satisfaction and infant temperament were self‐reported. No differences were found in the infants' behavior toward mother and father or in the time spent with each parent. Mothers' and fathers' relational behavior during parent‐infant episodes were generally comparable, yet mothers vocalized more and the latency to father's displaying positive affect was longer. Conditional probabilities indicated that under conditions of coparental mutuality, fathers showed more positive behaviors than mothers. Lag‐sequential analysis demonstrated that change in the infant's social focus between parents followed change in coparental behavior. Fathers' coparental mutuality was independently predicted by maternal behavior during mother‐child episodes, father marital satisfaction, and infant difficult temperament, whereas mothers' coparental mutuality was only linked with fathers' relational behavior. Results highlight the importance of including a microlevel perspective on the family system at the first stages of family development.     

Early stages of initiative and environmental response

Research results on the association between maternal response to infant' initiative and the development of such initiatives is being presented. This study is based on 239 feeding situations belonging to 41 mother–infant pairs videotaped at home at 30-day intervals, from the beginning of spoon-feeding until 1 year of age. The results showed that the basic hypotheses of this study were confirmed. There was a clear association between maternal responses to initiatives of the infant and four variables: Initiatives, Attempted Initiatives, Aversive Behavior, and Conflictivity. A favorable maternal response went along with more initiatives, fewer Attempts, less Aversivity, and less Conflictivity. Conflictivity was understood as reciprocal exchange of antipathetic reactions such as opposition, disgust, and hostility. Therefore, conflicts show struggle and confrontation between both members of the interaction. Aversivity is the infant's sole reaction to disgust, distaste, or opposition. As the infant risks confrontations with the care-giver to sustain her initiatives, we can say that, although highly influentiable by maternal response, Initiative is a contribution of the infant to her own development. Thus, in our view, a developing self shows an emerging capacity to initiate actions of his/her own. This becomes a relational issue as soon as the infant's initiative hits the interactional field, causing an environmental response that ultimately will allow or impede initiative. In case of impediments, the strong reaction of the infant will produce an impact upon the progressive stages of construction of the relationship, and certainly will be influential upon the further development of the infant's self.     

The integration of cognition and emotion during infancy and early childhood: regulatory processes associated with the development of working memory

This study was an attempt to integrate cognitive development (i.e., cognitive control) and emotional development (i.e., emotion regulation) in the first years of life. The construct of temperament was used to unify cognition and emotion because of its focus on attentional and regulatory behaviors. Children were seen at 8 months and 412-years of age in a study designed to examine the correlates of working memory development. Frontal brain electrical activity and temperament predicted working memory performance at 8 months. Similarly, frontal brain electrical activity, temperament, and language predicted working memory at age 412-years. Temperament in early childhood mediated the relation between infant temperament and early childhood working memory performance. These associated temperament characteristics highlight the value of early-learned regulatory and attentional behaviors and the impact of these early skills on later development.     

Maternal sensitivity behavior and infant behavior in early interaction

Maternal sensitivity behavior and infant behavior in early interaction were investigated among 57 Finnish mother–child pairs. Their interaction was video‐recorded at home in free‐play situation when the infants were 3 months and 12 months of age, and evaluated using the Parent–Child Early Relational Assessment Scale (PCERA). Maternal sensitivity behavior was mainly related to infant's positive aspects of mood, social and play behavior, and visual contact, both at 3 months and 12 months of age. Even though maternal sensitivity behavior correlated to infant behavior at 3 months and 12 months, infant behavior at 3 months of age contributed to later maternal sensitivity behavior. ©2001 Michigan Association for Infant Mental Health.     

Maternal sensitivity,infant co-operation and early linguistic development: Some predictive relations

Maternal sensitivity and infant co-operation during free play was analysed at the infant's age of 10 months and their contributions to early communicative and linguistic development at 12 months as well as later language outcome at 30 months were examined. In addition, the possible predictions of early skills to later development were considered. The participants were 27 Finnish-speaking mother – infant dyads. According to the results maternal sensitivity was associated with early intentional communication—particularly the use of communicative gestures, and also with symbolic behaviour and later comprehensive skills. No associations between infant co-operation and communicative and linguistic skills were found. As for expressive language skills, early capacities correlated with later outcome. The findings of the present study suggest that the effects of both maternal sensitivity and child characteristics on language development are likely to be specific rather than global.     

Infant Developmental Outcomes: A Family Systems Perspective

The aim of the current study was to examine whether parental mental health, parent–infant relationship, infant characteristics and couple's relationship factors were associated with the infant's development. Forty‐two families took part at three time points. The first, at 3 months postpartum, involved a video recorded observation (CARE‐index) of parent–infant interactions. At 5 months postpartum, in‐depth clinical interviews (the Birmingham Interview of Maternal Mental Health) assessed parental mental health and parental perceptions of their relationship with their infant, their partner and their infant's characteristics. Finally, the Bayley Scales III was carried out 17 months postpartum to assess the infants' cognitive, language and motor development. A higher mother–infant relationship quality was significantly associated with more optimal language development, whilst a higher father–infant relationship quality was associated with more advanced motor development. Additionally, maternal postnatal post‐traumatic stress disorder had a negative impact on the infant's cognitive development, whilst maternal prenatal depression was associated with a less optimal infant's language development. The largest prediction was afforded by parental perceptions of their infant's characteristics. The findings indicate that such perceptions may be crucial for the infant's development and imply that negative internal parental perceptions should be considered when assessing risk factors or designing interventions to prevent negative child outcomes.

Measures of infant behavioral and physiological state regulation predict 54‐month behavior problems

This study investigated whether measures of infant temperament, regulatory disorders, and physiological reactivity and concurrent measures of family environment were predictors of child behavior problems at 54 months of age. The sample consisted of 23 children–mother dyads. The sample recruitment strategy emphasized testing both typical and fussy/difficult infants at 9 months of age. Children were categorized into low and high behavioral problem groups at 54 months of age. The children in the high behavioral problem group were more likely at 9 months to have been temperamentally difficult, to have been classified as regulatory disordered, and to have displayed respiratory sinus arrhythmia (RSA) regulation difficulties. These children also were more likely to come from families described as less cohesive and providing less focus on active/recreational activities when the children were 54 months old. A logistic regression analysis, including only the 9‐month infant measures (i.e., difficultness, regulatory disorders classification, and RSA regulation), resulted in a significant model with 100.0% accurate classification into high or low behavioral problem groups. Data suggest that infant measures of behavioral and physiological state regulation may be early indicators of child behavior problems, especially internalizing problems.     

Convergence of multiple sources of information on infant individuality: neonatal behavior,infant behavior,and temperament reports

To shed light on the notion of enduring individual infant characteristics, convergence of three presumably interrelated measures of infant individuality was examined. Data collected included standardized behavioral assessments of the newborn (NBAS), maternal reports of infant temperament (at 3 and 9 months), and naturalistic observations of infant behavior at 1, 3, and 9 months. Infant temperament reports were significantly stable from 3 to 9 months; observed infant fussiness was significantly stable from 1 to 3 and 3 to 9 months; observed altertness/social responsiveness was not stable over time. Analyses of convergence of neonatal and infant behavior revealed that 9-month infant alertness/social responsiveness was significantly correlated with neonatal habituation. Similar analyses of neonatal behavior and reported temperament revealed that 3-month reported dullness was significantly correlated with neonatal habituation and range of state. At 9 months, temperament ratings of infant fussiness and unpredictability were significantly correlated with autonomic stability; fussiness was also significantly correlated with regulation of state. Finally, no significant relationships were observed between reported temperament and observed infant behavior. These results fail to support a simple notion of enduring individuality in infants over their first year of life.     

Nonmaternal care hours and temperament predict infants’ proximity-seeking behavior and attachment subgroups

Using the NICHD Early Childcare dataset (N = 1281), this study examined whether infant temperament and the amount of time infants spend in nonmaternal care independently predict (1) the likelihood that they seek comfort from their mother when needed and (2) placement in a particular subgroup of infant-mother attachment patterns. Mothers reported the number of hours their infant spent in nonmaternal care each month and their infant's difficulty adapting to novel stimuli at 6 months. The degree to which 15-month-old infants seek comfort from their mother during reunion episodes in the Strange Situation was observed using two behavioral scales (“proximity seeking” and “contact maintaining”). Their average score forms the outcome variable of “proximity-seeking behavior.” The other outcome variables were the subgroups of infant-mother attachment patterns: two subgroups for insecure babies (resistant and avoidant) and four subgroups for secure babies (B1, B2, B3, and B4). Easy adaptability to novel stimuli and long hours of nonmaternal care independently predicted a low level of proximity-seeking behavior. These predictors also increased the likelihood of an insecure infant being classified as avoidant (vs. resistant). A secure infant with these same predictors was most likely to be classified as B1, followed by B2, and then B3, with B4 being the least likely classification. Although previous studies using the NICHD dataset found that hours of nonmaternal care had no main effect on infants’ attachment security (vs. insecurity), this study demonstrates that hours of nonmaternal care predict the subcategories of infant-mother attachment.     

Can We Identify Emotion Over‐regulation in Infancy? Associations with Avoidant Attachment,Dyadic Emotional Interaction and Temperament

Emotion over‐regulation in infancy has seldom been the focus of empirical research. This study analysed the specificities of over‐regulation when compared with under‐regulation (maladaptive) and adaptive regulation by testing its association with attachment, dyadic emotional interaction, and temperament. The sample consisted of 52 low‐risk mother–infant dyads. During a home visit, dyadic emotional interaction was assessed in the daily routines and free play of 10‐month‐old infants. The infant's emotion regulation was assessed using the Shape Sorter Task, and a temperament questionnaire was completed by the mother. Attachment was assessed at 12 or 16 months using the Strange Situation. As hypothesized, (i) emotion over‐regulation (versus adaptive regulation) was predicted by a lower quality of dyadic emotional interaction and marginally by avoidant attachment; (ii) over‐regulation (versus under‐regulation) was predicted by avoidant attachment; and (iii) the predictive role of avoidant attachment was substantiated after controlling for another measure of mother–infant interaction. Contrary to expectations, temperament did not distinguish between emotion regulation styles. The link between over‐regulation and lower quality of mother–infant emotional interaction and avoidant attachment was demonstrated. There is empirical support to the claim that it is possible to identify emotion over‐regulation in infancy and that it is a maladaptive style of emotion regulation.

Maternal recollected anxiety and mother–infant interaction in preterm infants

This study focused on the relationship between maternal recollected anxiety and the quality of mother–preterm infant interaction. In a observational study, 52 mothers and their preterm infants were videotaped at home in a standardized object–play interaction situation, at the infant's age of 6 months. Observations concentrated on different aspects of maternal behavior, including sensitive responsiveness, involvement, level of activity, and intrusiveness. Mothers were interviewed about their experiences during the period of neonatal intensive care and were, on the basis of their answers, divided into high‐anxiety and low‐anxiety mothers. In general, and independent of the infant's current interactive behavior and medical status, high‐anxiety mothers were more intrusive and more active during interaction with their infants than were mothers who recalled little or no anxiety during the postnatal period. ©1999 Michigan Association for Infant Mental Health.     

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.

Paternal influences on infant temperament: Effects of father internalizing problems,parenting-related stress,and temperament

Temperament ratings were obtained from 98 fathers when their infants were 4 and 6 months of age to examine effects of paternal characteristics on infant temperament. Parental stress, internalizing symptoms, and father's temperament were considered as factors possibly contributing to differences in their child's temperament.     

Vocal imitation between mothers and infants

The aim of the present mixed cross-sectional and longitudinal study was to observe and describe some aspects of vocal imitation in natural mother-infant interaction. Specifically, maternal imitation of infant utterances was observed in relation to the imitative modeling, mirrored equivalence, and social guided learning models of infant speech development. Nine mother-infant dyads were audio-video recorded. Infants were recruited at different ages between 6 and 11 months and followed for 3 months, providing a quasi-longitudinal series of data from 6 through 14 months of age. It was observed that maternal imitation was more frequent than infant imitation even though vocal imitation was a rare maternal response. Importantly, mothers used a range of contingent and noncontingent vocal responses in interaction with their infants. Mothers responded to three-quarters of their infant's vocalizations, including speech-like and less mature vocalization types. The infants’ phonetic repertoire expanded with age. Overall, the findings are most consistent with the social guided learning approach. Infants rarely imitated their mothers, suggests a creative self-motivated learning mechanism that requires further investigation.     

Mother's prenatal and postpartum depression symptoms and infant's sleep problems at 6 months

Mother's prenatal and postpartum depression have been associated with infant's sleep problems. This study aimed to analyze (a) the effects of mother's prenatal and postpartum depression symptoms, including the effects of prenatal and postpartum anxiety and depression scores of the Edinburgh Postnatal Depression Scale (EPDS), on infant's sleep problems at 6 months, and (b) the interaction effect between mother's prenatal and postpartum depression symptoms and infant's sex on infant's sleep problems at 6 months. The sample was comprised of 164 mother–infant dyads whose mothers completed measures of depression at the third trimester of pregnancy, 2 weeks, 3 and 6 months postpartum and a measure of infant's sleep problems at 6 months (CSHQ-I). Mother's prenatal depression symptoms, specifically depression scores of the EPDS, predicted more infant's sleep anxiety and daytime sleepiness, while mother's depression symptoms at 2 weeks postpartum, specifically anxiety scores of the EPDS, predicted more bedtime resistance and CSHQ-I total scores at 6 months. Boys of mothers with more prenatal depression symptoms presented more sleep anxiety at 6 months. Both mother's prenatal and early postpartum depression symptoms have a negative effect on the emergence of infant's sleep problems. Additionally, boys seem more vulnerable to mother's prenatal depression symptoms.     

Early tactile experience of low birth weight children: links to later mental health and social adaptation

The purpose of this study was twofold: to determine (1) the degree to which specific qualities of maternal touch may contribute to the low birth weight infant's emotional and behavioural problems as well as social adaptation, and (2) the relationship between maternal touch and a mother's other caregiving behaviour. The sample included 114 socioculturally diverse infants and their mothers who were videotaped during an infant feeding when the baby was 3 months old. This videotape was analysed to assess dimensions of mother–infant interaction, including maternal touch. Data on perinatal risk and the mother's acceptance versus rejection of the infant were also acquired. Social adaptation and emotional/behavioural problems were measured when the child was 2 years of age. Hierarchical regression analyses indicated that maternal touch accounted for 15% of the variance in the likelihood of a child having emotional/behavioural problems at age 2. Children who received more nurturing touch had significantly fewer internalizing problems (such as depression) while children receiving both more frequent touch and harsh touch had more externalizing problems (such as aggressive behaviour). Infants who were less responsive to their caregivers were especially at risk of developing aggressive/destructive behaviour as a result of frequent touch. But less responsive infants also appeared to benefit most from greater use of diverse types of maternal touch, accounting for 6% of the variance in superior adaptive behaviour at age 2. Nurturing touch was the only quality that showed even a modest relationship to other caregiving behaviour, suggesting that touch may play a distinct role in the infant's psychosocial development.

Pathways from marital aggression to infant emotion regulation: the development of withdrawal in infancy

Associations between marital conflict and infant emotion regulation exist, but explanatory pathways have not been explored. For older children, parental behavior partially mediates this association through a "spillover" process. We test: associations between mothers' and fathers' verbally aggressive marital conflict, infant temperament, and infant withdrawal; mediating effects of negative maternal behavior, and moderating effects of infant temperament, exposure to marital arguments, and contact with father. Eighty mothers, 73 fathers, and their 6-month-old infants participated; parents reported marital aggression prenatally, mothers reported infant exposure to arguments, direct caregiving by father, and infant temperament at 5 months. Negative maternal behavior, infant withdrawal, distress to novelty, activity, and look away were observed at 6 months. Mothers' and fathers' aggressive marital conflict predicted infant withdrawal, interactively with exposure to marital arguments and extent of father caregiving, as did infant temperament and negative maternal behavior. Maternal behavior did not mediate between marital conflict and withdrawal.
