Consistency in infant sleeping arrangements and mother–infant interaction

This study examined the association between infant sleeping arrangements (i.e., habitual co‐sleeping, inconsistent co‐sleeping, and non‐co‐sleeping) and quality of mother–infant interaction during play in a sample of mothers, each with a typically developing infant (N=70). Mother–infant dyads who experienced consistency in infant sleeping arrangements in a typical week at 6 months (i.e., habitual co‐sleeping or non‐co‐sleeping) were characterized by more positive maternal and infant behavior and dyadic quality of interaction at 9 months compared with dyads who experienced inconsistency in sleeping arrangements. Additionally, a greater amount of co‐sleeping per week was associated with an increased duration of breastfeeding, mothers working fewer hours, less infant temperamental intensity, and less maternal depression. This study underscores the advantages of empirically based studies that consider consistency in infant sleep experience as a factor that is associated with more positive mother–child interaction.     

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.     

Changing patterns of infant behavior and mother–infant interaction: Intra- and interindividual variability

Mother–infant dyads were observed weekly at their homes for a 15-month period. In this way longitudinal data about the infants’ crying, fretting/fussing, smiling and different types of physical contact with the mother were collected. The subject of this study concerns the variability and stability in macroscopic patterns of associations between these behaviors. Different types of associations were found between the behaviors, and most of them changed considerably as the infant developed. Individual differences in the nature of the associations and in the changes they underwent over time predominated, but in a limited number of cases the infants shared the same developmental trajectories of behavioral associations. The results show how the use of intensive time series designs can be advantageous in clarifying issues of long-term variability and stability in human behavior. They also support the notion of changing patterns of behavior being a normal feature of early development.     

Child's behaviour in mother–child interaction predicts later emotional and behavioural problems

The aims were to examine the association of maternal or child interactive behaviour with emotional and behavioural problems of the child simultaneously and 3 years later, and to assess whether there is continuity in children's emotional and behavioural symptoms from 2 to 5 years. Sixty‐five 2‐year‐old children with their mothers were videotaped during a feeding situation. Their mothers completed the CBCL at 2 years and when the children were 5. Simultaneously, there were no strong correlations between child's emotional and behavioural problems and maternal or child interactive behaviour. Subsequently, mothers' higher sensitivity and more optimal structuring, as well as child's higher involvement of the mother, were associated with lower levels of child externalizing and total problem scores. Also, less responsive children showed more externalizing symptoms 3 years later. There was continuity of emotional and behavioural problems from 2 to 5 years. Problems in mother–child interaction may predict behavioural problems in the child subsequently. Besides maternal behaviour, it is important to consider the interactive behaviour of the child. Children who are less responsive and who show less involvement of the mother are more likely to subsequently present more externalizing symptoms, and these children should be recognized and treated early.

Tonal synchrony in mother–infant interaction based on harmonic and pentatonic series

This study reports the occurrence of ‘tonal synchrony’ as a new dimension of early mother–infant interaction synchrony. The findings are based on a tonal and temporal analysis of vocal interactions between 15 mothers and their 3-month-old infants during 5 min of free-play in a laboratory setting. In total, 558 vocal exchanges were identified and analysed, of which 84% reflected harmonic or pentatonic series. Another 10% of the exchanges contained absolute and/or relative pitch and/or interval imitations. The total durations of dyads being in tonal synchrony were normally distributed (M = 3.71, SD = 2.44). Vocalisations based on harmonic series appeared organised around the major triad, containing significantly more simple frequency ratios (octave, fifth and third) than complex ones (non-major triad tones). Tonal synchrony and its characteristics are discussed in relation to infant-directed speech, communicative musicality, pre-reflective communication and its impact on the quality of early mother–infant interaction and child's development.     

Infant irritability and early mother–infant reciprocity patterns

This study investigated how various forms of neonatal irritability (at 3 days) and irritability at 10 weeks are related to reciprocal interactions between mothers and their infants. Fifty‐six fullterm, first‐born male infants were examined using the Neonatal Behavioral Assessment Scale (NBAS‐K) at 3 days postpartum. Each infant was rated for irritability to aversive stimuli, general irritability, consolability and responsiveness to visual–auditory stimuli. At 10 weeks of age, during a home visit, mother–infant reciprocity was scored for gaze, smile, vocalization and hold behaviors. Based upon maternal reports and behavioral observations, infant irritability was scored at 10 weeks using the NBAS‐K scoring system. Findings revealed that: (1) there were two distinct forms of reciprocity: social and physical; (2) general irritability at 3 days was negatively related to reciprocal hold interaction and positively related to reciprocal social interaction at 10 weeks, and (3) neonatal irritability to aversive stimuli (at 3 days) was positively related to subsequent reciprocal social interaction. Regression analyses showed that neonatal variables were the foremost predictors of reciprocal hold at 10 weeks. Findings are discussed in terms of (1) the need to differentiate between social and physical behavioral patterns, and (2) time‐lag effects with respect to mother–infant interactions.

Quality of attachment,perinatal risk,and mother–infant interaction in a high‐risk premature sample

Thirty‐three families, each with a premature infant born less than 33 gestational weeks, were observed in a longitudinal exploratory study. Infants were recruited in a neonatal intensive care unit, and follow‐up visits took place at 4 months and 12 months of corrected age. The severity of the perinatal problems was evaluated using the Perinatal Risk Inventory (PERI; A.P. Scheiner & M.E. Sexton, 1991 ). At 4 months, mother–infant play interaction was observed and coded according to the CARE‐index (P.M. Crittenden, 2003 ); at 12 months, the Strange Situation Procedure (SSP; M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978 ) was administered. Results indicate a strong correlation between the severity of perinatal problems and the quality of attachment at 12 months. Based on the PERI, infants with high medical risks more frequently tended to be insecurely attached. There also was a significant correlation between insecure attachment and dyadic play interaction at 4 months (i.e., maternal controlling behavior and infant compulsive compliance). Moreover, specific dyadic interactive patterns could be identified as protective or as risk factors regarding the quality of attachment. Considering that attachment may have long‐term influence on child development, these results underline the need for particular attention to risk factors regarding attachment among premature infants.     

Maternal substance use and mother–infant feeding interactions

The purpose of this study was to examine the impact of maternal polydrug cocaine use during pregnancy and associated risk factors such as maternal psychopathology and negative infant temperament on the quality of mother–infant feeding interactions at 2 months of infant age. Participants were 45 mother–infant dyads (19 cocaine‐exposed and 26 nonexposed) who were recruited at birth and assessed again 2 months of infant age. Mother–infant interactions during feeding were videotaped and coded with regard to dyadic reciprocity, maternal noncontingency, and dyadic conflict. Results indicated that maternal cocaine use was associated with higher dyadic conflict. Moreover, cocaine‐using mothers were also more likely to use marijuana and alcohol, and use of such substances was associated with lower dyadic reciprocity and higher maternal noncontingency during interactions. Results also suggested that one pathway to higher dyadic conflict during interactions among cocaine‐using mothers was through the impact of cocaine on infant risk conditions like lower gestational age and negative temperament (e.g., higher distress to novelty). Interventions focusing on promoting the quality of mother–infant interactions in combination with substance abuse treatment may be especially promising for this population. ©2001 Michigan Association for Infant Mental Health.     

Neonatal imitation in a mother–infant setting

Imitation of tongue protrusions and mouth openings was investigated in 18 newborn infants using a procedure differing in three ways from previous laboratory studies: the mother presented the target gestures, she was permitted to adjust to the infant's reactions, and the infant's baseline response rate was assessed during face-to-face interaction. This procedure was assumed to facilitate infant imitation. Compared with baseline responses in face-to-face interaction, both tongue protrusions and mouth openings were imitated in the two conditions. No imitation, however, was found when the responses in the two imitation conditions were compared. These results are less convincing than those found in strictly controlled laboratory experiments. A less restrictive procedure did not, therefore, promote imitation. The mixed results could be explained by too short an exposure to the target gesture. If repeated and insistent gesturing is a crucial condition, neonatal imitation might be understood to be the result of instruction and teaching, rather than a means of mutual communication. © 1998 John Wiley & Sons, Ltd.     

Kangaroo mother care and mother‐premature infant dyadic interaction

The aim of this study was to investigate the psychological impact of Kangaroo Mother Care (KMC) on mother‐infant bonding in cases of premature delivery. Examined variables were mother‐infant relationships, maternal anxiety levels, and infant interactive signals. The KMC method requires that babies be undressed and held upright between their mother's breasts for a minimum of 1 hr a day, from birth until they are discharged from hospital. The present study examined 40 premature infants and their mothers, with 21 dyads experiencing KMC and 19 receiving traditional care (TC). Maternal emotional stress was assessed with the Parent Stress Index‐Short Form questionnaire (Abidin, 1990), and mother‐newborn interactive style was assessed with the Nursing Child Assessment Feeding Scale (Barnard, 1975). Results revealed a better mother‐infant interactive style, a significant decrease in maternal emotional stress, and better infant ability to make requests and respond to parental interactive style in the KMC group.     

Infant touching behaviour during mother–infant face‐to‐face interactions

The study of infant communication during mother–infant interactions has largely focused on infants' distal behaviours, while neglecting their more proximal behaviours, such as touch. Yet, touch is an important modality through which infants and mothers communicate; it is also a vital means through which infants self‐regulate and explore their surroundings. The present study was designed to investigate the touching behaviours of 44, 51/2‐month‐old, healthy, full‐term infants during face‐to‐face mother–infant interactions. A still‐face (SF) procedure was used in order to examine differences in the types and locations of infant touch across normal and perturbed interaction periods, when mothers exhibit changes in their emotional availability. Results revealed that infant touch varied with changes in maternal availability. During the SF period, when mothers were unavailable, infants used more active, soothing, and reactive tactile behaviours (stroke, finger, pat, and pull), and they spent more time touching themselves. In contrast, infants used mostly passive touch (static) during the Normal periods, when their mothers were available. They also spent a significant portion of time touching their mothers. The variations in infant touch across periods suggest that infants communicate their affective states through touch. The findings also support the regulatory and exploratory roles of infant touch, especially during periods of maternal unavailability. Copyright © 2007 John Wiley & Sons, Ltd.     

Breastfeeding and the mother–infant relationship—A review

A positive effect of breastfeeding on the mother–infant relationship is often assumed in the scientific literature, but this has not been systematically reviewed. This review aims to clarify the role of breastfeeding in the mother–infant relationship, which is conceptualized as the maternal bond toward the infant and infant attachment toward the mother. Our findings indicate that theoretical mechanisms through which breastfeeding may enhance the maternal bond or infant attachment (i.e., endocrine and sensory factors involved in breastfeeding) can be found in both humans and animal models. However, the few empirical studies investigating this association have not found convincing support for a relation between breastfeeding and the quality of the mother–infant relationship. We therefore conclude that assumptions on a positive role of breastfeeding on the mother–infant relationship are not supported by empirical evidence, and recommendation of breastfeeding should solely be based on its well-documented positive effects on infant and maternal health.     

Quantitative evaluation of infant behaviour and mother–infant interaction: An overview of a japanese interdisciplinary programme of research

This paper provides an overview of an interdisciplinary programme of research started more than 20 years ago at the University of Tokyo. A major aim of this programme was (and still is) to develop methods and related forms of quantitative analysis that provide rigorous evaluations of infant behaviour from a particular theoretical perspective. In one part of the programme telethermography is used to measure emotional changes in young infants. Contrary to the accepted view in attachment theory, infants as young as 2–3 months showed evidence of stress following separation from the mother (as indexed by a drop in the skin temperature of the infant's forehead). In another part, we established the presence of interpersonal synchrony between arm movements of the newborn and the speech of the mother and other adults, using computer assisted pattern recognition techniques. On the basis of this finding, we have proposed a simulation model of mother-infant interaction from the perspective of system information theory. In general, our programme of research provides a theoretically driven set of techniques and analytical approaches that may provide deeper insights into early development and parenting.     

Brief mother–infant treatment: Psychoanalytically informed video feedback

Specific patterns of interactive regulation documented by microanalytic methods of infant research can be applied to clinical interventions with mothers and infants. A brief treatment model is described that includes face‐to‐face split‐screen videotaping (one camera on each partner) and therapeutic observation of the videotape with the parent. The intervention uses “video feedback” informed by a psychoanalytic approach, including positive reinforcement, modeling, and information giving, as well as interpretation, while watching the videotape. Specific interactions in the areas of attention, arousal, affect, and timing regulation are evaluated. The psychoanalytic intervention links the “story” of the presenting complaints, the “story” seen in the videotape, and the “story” of the parent's own upbringing. An attempt is made to identify specific representations of the baby that may interfere with the parents's ability to observe and process the nonverbal interaction. The mother's powerful experience of watching herself and her baby interact, and our joint attempts to translate the action‐sequences into words, facilitates the mother's ability to “see” and to “remember,” stimulating a rapid integration of the mother's procedural and declarative modes of information‐processing. One treatment case, involving six contacts, is presented to illustrate the approach. By applying the specificity of interactive regulation identified by microanalysis of videotape into the psychodynamic treatment of mother–infant pairs, basic research can be translated into clinical practice. ©2003 Michigan Association for Infant Mental Health.     

Let it be: Accepting negative emotional experiences predicts decreased negative affect and depressive symptoms

The present studies examined whether a tendency to accept negative emotional experiences buffers individuals from experiencing elevated negative affect during negative emotional situations (Study 1) and from developing depressive symptoms in the face of life stress (Study 2). Both studies examined female samples. This research expands on existing acceptance research in four ways. First, it examined whether acceptance has beneficial correlates when it matters most: in emotionally taxing (versus more neutral) contexts. Second, in Study 2 a prospective design was used in which acceptance was measured before stress was encountered and before outcomes were measured. Third, depressive symptoms (rather than general functioning or trauma symptoms) were examined as a particularly relevant outcome in the context of stress. Fourth, to enhance generalizability, a community sample (versus undergraduates or a purely clinical sample) was recruited. Results indicated that acceptance was correlated with decreased negative affect during a negative emotion induction but not an affectively neutral condition (Study 1). In Study 2, acceptance interacted with life stress such that acceptance predicted lower levels of depressive symptoms after higher, but not lower, life stress. These results suggest that accepting negative experiences may protect individuals from experiencing negative affect and from developing depressive symptoms.     

Mothers' thoughts about their children: Links between mind‐mindedness and emotional availability

Maternal mind‐mindedness (MM) and emotional availability (EA) were examined in 89 middle‐class mothers and their 4‐year‐old children. Each mother‐child dyad was videotaped in their home during a 20‐minute play interaction and aspects of EA (sensitivity, structuring, intrusiveness, and hostility) were assessed using the EA scales ( Biringen, Robinson, & Emde, 1998 ). Meins, Fernyhough, Russell, and Clark‐Carter's (1998) maternal interview was used to measure MM and the proportion of mental comments was calculated. Mothers who used a higher proportion of mental comments tended to demonstrate less hostility during interaction with their child. The findings are discussed in relation to the need to consider other interactional variables, in addition to maternal sensitivity, when examining how parental representations are transmitted to children.     

Affect expression in prenatally psychotropic exposed and nonexposed mother–infant dyads

This prospective study examined infant, maternal, and dyadic affective profiles at three months postpartum in infant–mother dyads that were exposed to psychotropic medications in utero compared with nonexposed control dyads. Control dyads of nondepressed mothers and their infants showed many similarities in affect expression with mother–infant dyads who were exposed to selective serotonin reuptake inhibitors (SSRIs) alone for treatment of maternal depression. In contrast, mothers who received SSRIs and Rivotril (Benzodiazepine derivative) for treatment of depression and anxiety expressed both positive and negative affect towards their infants. Clinical implications regarding use of psychotropic medications such as SSRIs alone or in combination with other drugs for treatment of maternal anxiety and depression during pregnancy are discussed. Clinicians should be aware of the possible differential response in maternal–infant interaction in a mixed diagnosis group (i.e., depression and anxiety) regarding infant temperament, possibly suggesting latent behavioral teratogenicity with psychotropics. ©2002 Michigan Association for Infant Mental Health.     

The influence of prematurity,maternal anxiety,and infants' neurobiological risk on mother–infant interactions

In this study, we investigated how the birth of a very low birth weight preterm (VLBW) infant influences the mother–infant interaction at 3 months. We also focused on the impact of the infant's neurobiological risk and maternal anxiety, and their interaction. The comparison of the VLBW preterm sample (n = 79) with an external full‐term sample (n = 35) showed mother–infant interactions of the families with the preterm infant to be more vocally responsive during the interaction, but less facially responsive during the interaction. Additionally, higher levels of maternal anxiety were associated with preterm infants being less facially responsive in interaction with their mother. While neurobiological risk of the infant played a part in this association, with higher risk infants also being less facially responsive, the relationship with maternal anxiety and the mother–child interaction was stronger. How these findings may influence therapeutic interventions is discussed.
