The Relation between Mothers' Mirroring of Infants' Behavior and Maternal Mind‐Mindedness

Maternal mind‐mindedness, which is a measure of maternal mentalization involving mothers' speech, was examined as a predictor of mothers' mirroring of infant behavior during interaction. Five‐month‐old infants and their mothers engaged in a Still‐Face Task in which the mother's mirroring of the infant's behavior was assessed. After the task, the mother was shown a video of her infant in the task and asked to comment on what was happening for her infant; her comments were assessed for mind‐mindedness. Maternal mind‐mindedness when mothers were asked to reflect upon what was happening for their infants during the task predicted mothers' mirroring behaviors while engaged with their infants in the task. Maternal mirroring behavior may be a manifestation of maternal mentalization that is salient to infants.     

Relationship Between Maternal Sensitivity During Early Interaction and Maternal Ability in Perceiving Infants' Body and Face

Maternal sensitivity has been considered an indicator of mother‐infant quality interaction, however little is known about the perception processes associated to this parental behavior style. Here we aimed to explore the relationship between maternal sensitivity during a face‐to‐face interaction with their infants and maternal ability in perceiving infants' body and face. Thirty‐six 6 month‐old infants and their mothers were videotaped during a mother‐infant interaction to identify those with high and low sensitivity. Then, mothers were tested using an inversion effect paradigm requiring the visual discrimination of upright and inverted pictures of whole bodies and faces of their own and unfamiliar infants; this allowed estimation of their configural perceptual processing abilities. Results showed that high‐sensitivity mothers showed reduced body configural processing for others' infants as compared to configural processing of their own infant, whereas low‐sensitivity mothers were engaged in comparable body configural processing independently from infant identity. Infants' face configural processing did not distinguish between high‐ and low‐sensitivity mothers. Our findings suggest that high‐sensitivity mothers have refined their use of configural processing of body postures to be selective for their own infants, suggesting that this visuo‐perceptual strategy makes much more efficient the mothers' ability in detecting, discriminating and recognizing own infant's cues.     

The Regulation of Infant Negative Emotions: The Role of Maternal Sensitivity and Infant‐Directed Speech Prosody

This study explored the role of maternal sensitivity and infant‐directed speech (IDS) prosody in infants’ expression and regulation of negative emotion. Seventy mothers and their 3‐month‐old infants were observed during the Still‐Face Paradigm (SFP). Maternal sensitivity and IDS prosody were assessed at baseline and infant negative affect in the baseline, still‐face, and reunion episodes. Results showed that prototypical IDS prosody characterized by wider fundamental frequency (F0) variability was related to decreases in infant's negative affect, but only if accompanied by maternal sensitivity. Infants of sensitive mothers who spoke with more prototypical IDS prosody showed better abilities to regulate negative affect during the SFP. When prototypical IDS prosody was accompanied by low maternal sensitivity, infants showed lower regulation of negative emotions. In conclusion, infant negative affect regulation in a dyadic setting is facilitated by an optimal combination of both more prototypical maternal IDS prosody and maternal sensitive responsiveness. Implications for the study of mother–infant interaction are discussed.     

Associations Between Maternal Postpartum Depression,Infant Social Behavior With a Stranger,and Infant Cognitive Development

Maternal postpartum depression (PPD) has been found to be related to infant social withdrawal during mother–infant interaction, and this may spill over on infant interactive behavior in other social contexts and impact infant psychosocial development. We investigated whether PPD was associated with infant social withdrawal during interaction with a tester in a psychological test situation and whether infant social withdrawal in the test situation mediated the association between PPD and infant cognitive scores reported in a previous study. Participants were 28 PPD dyads and 41 control dyads. We assessed infant social behavior and cognitive development with the Alarm Distress Baby Scale and the cognitive scale of the Bayley Scales of Infant and Toddler Development, third edition, at four months. More symptoms of maternal depression were associated with more infant social withdrawal. The association between maternal depressive symptoms and cognitive scores was at most partially mediated by infant social withdrawal in the test situation (<29.6%). Our results add to the existing literature on the effects of PPD on infant social behavior in other contexts than the one constituted by the mother. More research is needed to shed light on the mechanisms through which PPD impacts infant cognitive development.     

Prenatal Reflective Functioning and Accumulated Risk as Predictors of Maternal Interactive Behavior During Free Play,the Still‐Face Paradigm,and Two Teaching Tasks

This study examined whether prenatal reflective functioning (RF) was related to mothers’ interactive style across contexts with their 6‐month‐old infants (M age = 6.02 months, SD = 0.41, 54% boys), and to what extent quality of prenatal RF could account for the influence of accumulated risk on maternal interactive behavior. Accumulated risk was defined as the sum‐score of a selection of risk factors that have been associated with suboptimal infant development. Mother–infant dyads (N = 133) were observed during free play, two teaching tasks, and the Still‐Face Paradigm (SFP). Better prenatal RF was associated with more positive maternal behavior in all settings and less negative behavior during teaching and SFP reengagement. Accumulated risk and prenatal RF predicted shared variance in maternal interactive behavior (with unique predictive effects observed only for RF on sensitivity during teaching and SFP play, and for accumulated risk on sensitivity and positive engagement during SFP play, and internalizing‐helplessness during SFP reengagement). Accumulated risk had an indirect effect on maternal sensitivity during teaching and SFP play through prenatal RF. These findings suggest not only that RF may be targeted prenatally to improve mother–infant interactions, but also that enhancing RF skills may ameliorate some of the negative consequences from more stable perinatal risk factors that influence parent–child interactions.     

The Association Between Cigarette Smoking During Pregnancy and Maternal Behavior During the Neonatal Period

This study examined the association between maternal smoking during pregnancy and maternal behavior during mother‐infant interactions during the neonatal period. Participants included 84 mother‐infant dyads (43 cigarette‐exposed and 41 nonexposed) who were recruited after birth and assessed at 2 to 4 weeks of infant age. Results indicated that mothers who smoked during pregnancy had higher levels of maternal insensitivity (MI) and lower levels of maternal warmth (MW) during interactions with their infant even after controlling for demographics and pregnancy alcohol use. Maternal anxiety and hostility mediated the association between smoking and MI and maternal anger mediated the association between smoking and reduced MW. In addition, there was an interaction between infant gender and maternal smoking for MW with smokers displaying less warmth to boys during interactions.     

Mother‐ Versus Infant‐Centered Correlates of Maternal Mind‐Mindedness in the First Year of Life

We investigated whether maternal mind‐mindedness in infant–mother interaction related to aspects of obstetric history and infant temperament. Study 1, conducted with a socially diverse sample of 206 eight‐month‐old infants and their mothers, focused on links between maternal mind‐mindedness and (i) planned conception, (ii) perception of pregnancy, and (iii) recollections of first contact with the child. The two indices of mind‐mindedness (appropriate and nonattuned mind‐related comments) related to different aspects of obstetric history, but no strong associations were seen with socioeconomic status, maternal depression, or perceived social support. In Study 2, we found good temporal stability in both indices of mind‐mindedness in a sample of 41 infant–mother dyads between 3 and 7 months. Neither index of mind‐mindedness related to infant temperament. We conclude that mind‐mindedness is best characterized as a facet of the specific caregiver–child relationship, while also being influenced by stable cognitive–behavioral traits in the mother.     

The practical utility of the Welch Emotional Connection Screen for rating parent–infant relational health

Emotional Connection (EC) measured by the Welch Emotional Connection Screen (WECS) was related to the Parent–Infant Interaction Rating System (PIIRS), a 5‐point adaptation of the rating system developed for the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (e.g., NICHD Early Child Care Research Network, 1999, Developmental Psychology, 35, 1399). Parent–infant dyads (n = 49 mothers; 43 fathers) were videotaped during face‐to‐face interaction at infant age 6 months; interactions were coded with both the WECS and PIIRS. At age 3, mothers completed the Child Behavior Checklist. WECS ratings of EC were associated with PIIRS rating items for both mother–infant and father–infant dyads. Mother–infant EC related positively to maternal sensitivity and positive regard for child, child positive mood and sustained attention, and dyadic mutuality, and negatively with maternal intrusiveness. Father–infant EC related positively to fathers' positive regard for child, child positive mood and sustained attention, and dyadic mutuality. Mother–infant EC predicted child behavior problems at age 3 better than mother–infant PIIRS ratings of dyadic mutuality. With fathers, neither EC nor dyadic mutuality ratings predicted mother‐reported child behavior problems. Findings highlight the practical utility of the WECS for identifying potentially at‐risk dyads and supporting early relational health.     

Regulation of Jealousy Protest in the Context of Reunion Following Differential Treatment

Emotion regulation strategies and variation in their presentation were explored toward understanding infants' responses during reunion with mother (Re) following baseline mother–infant interaction (Bl) and differential treatment (DT) episodes. Correlation analyses revealed cohesion among distress and mother‐directed touch and proximity‐seeking during DT and Re, mother‐directed gaze during DT, and resistance during Re. The association between mother‐directed gaze during DT and distress during Re suggests that visual inattention during DT serves as a regulatory strategy. Overall, these linkages yield expanded understanding of jealousy protest as a constellation of responses that endures beyond the eliciting condition and includes regulatory behaviors. Cross‐context comparisons revealed that distress was lower during Re than during DT, but not as low as Bl, suggesting that DT poses challenge to interactive repair. Inquiry into individual variation revealed that distress during Re was augmented in laterborn males and with risk influences of dysregulated fear, and maternal insensitivity and hostility. Conversely, maternal depression was associated with less distress; later judgment as insecure, especially insecure‐avoidance, was associated with less mother‐directed behaviors. These findings suggest that dysregulation following DT is indicated by both resistance and passivity. In sum, the results highlight emotion regulation as a powerful framework for addressing recovery following DT.     

Differential Susceptibility to Parenting in Adolescent Girls: Moderation by Neural Sensitivity to Social Cues

This research examined whether heightened neural activation to social cues confers adjustment advantages in supportive social contexts but adjustment disadvantages in stressful social contexts. Forty‐five adolescent girls were exposed to social exclusion during an fMRI scan and reported on parent–child relationship quality and depressive symptoms. Stressful parent–child relationships predicted subsequent depressive symptoms in girls with high and moderate but not low dorsal anterior cingulate cortex, subgenual anterior cingulate cortex, and anterior insula activation during exclusion. In the context of supportive parent–child relationships, however, neural activation to exclusion predicted particularly low levels of depressive symptoms. This support for a biological sensitivity to context model suggests the possibility of redirecting adolescent girls’ neural sensitivity to social cues toward more positive adaptation.     

Relation Between Maternal Contingent Responsiveness and Infant Social Expectations

This study investigated the relation between maternal contingent responsiveness and 4‐ and 5‐month‐old infants' (N = 64) social expectation behavior in a still‐face procedure. Mothers were asked to interact with their infants for 2 min (interactive phase), remain still‐faced for 1 min (still‐face phase), and resume interaction for 2 min. Mother and infant behavior was assessed for the frequency of infant and mother smiles, mother smiles that were contingent to infant smiles and infant smiles were contingent to mother smiles during the interactive phase, and infant social bids to mother during the still‐face phase. Hierarchical regression showed that mother contingent smiles during the interactive phase accounted for unique variance in infant social bids during the still‐face phase beyond that accounted for by the frequency of mother and infant smiles during the interactive phase. These results support the view that young infants' social expectations and sense of self‐efficacy are formed within their interactions with their caregivers.     

Infant Nutrition and 12 and 18 Months Secure Base Behavior: An Exploratory Study

A notable omission in studies of developmental links to early nutritional deficiencies is infant attachment. In those few studies investigating associations between infant nutrition and attachment, nutrition was defined solely by physical growth, and infants had moderate–severe growth retardation. In this study, we utilized multiple markers of infant nutrition. Our sample consisted of 172 12‐month‐old Peruvian infants and their mothers from low‐income families, with a follow‐up assessment on 77 infants at 18 months. Infants were not severely malnourished, but did have micronutrient deficiencies. Anthropometry, dietary intake, and iron status were used as measures of infant nutrition. Based on infant behavior in a structured laboratory situation, Q‐sort techniques were used to rate three attachment markers: infant secure base behavior, interaction quality, and negative emotionality with mother. At 12 months, infant weight was positively related to interaction quality. At 18 months, infant iron status was positively related to secure base behavior. This pattern of findings remained even after statistically controlling for family socioeconomic status and maternal education. Our findings indicate that infant nutritional status is associated with markers of infant attachment and these associations are not restricted just to severely malnourished infants.     

Toddlers' Empathy‐Related Responding to Distress: Predictions From Negative Emotionality and Maternal Behavior in Infancy

This study focused on the predictive contributions of infants' temperamental negative emotionality (proneness to fear, anger), sex, maternal responsivity, and their interaction on toddlers' empathy‐related responding to distress in 3 contexts. Ninety‐eight infants and their mothers participated in a longitudinal study. When the infants were 10 months of age, mothers completed assessments of infant temperamental anger and fear, and maternal behaviors were observed in a free‐play setting. At 18 months of age, toddlers' empathy‐related responding to the distress of a stranger, a crying baby doll, and the mother was assessed. A series of hierarchical and logistic regressions were performed, and results indicated that infant fear predicted higher concerned awareness toward adults and higher personal distress reactions toward the mother. In addition, maternal responsivity predicted higher concerned attention and lower personal distress reactions toward the baby doll and mother. Findings also revealed several interaction effects to predict toddlers' empathy‐related responding to distress.     

Delivery Pain and the Development of Mother—Infant Interaction

This study examined delivery pain as a possible risk factor for the development of mother‐infant interaction. Eighty‐one mothers completed the Pain Catastrophizing Scale, the State‐Trait Anxiety Inventory, and the Edinburgh Postnatal Depression Scale. A retrospective evaluation of labor pain was performed using the Visual Analog Scale at 2 days postpartum. Six weeks after birth the mothers were visited at home, completed measures of anxiety and depression, and were observed during a free play session with the infant. The mother's tendency to catastrophize pain predicted lower levels of mother‐infant reciprocity at 6 weeks, controlling for maternal age, education, parity, epidural analgesia, pain perception, anxiety, and depression. Trait anxiety was related to lower maternal sensitivity. The mother's tendency to catastrophize pain was discussed in relation to the personality trait of exaggerated emotional perception of pain and its potential interference with the formation of the mother‐infant relationship.     

Infant‐Directed Speech Is Modulated by Infant Feedback

When mothers engage in infant‐directed (ID) speech, their voices change in a number of characteristic ways, including adopting a higher overall pitch. Studies have examined these acoustical cues and have tested infants' preferences for ID speech. However, little is known about how these cues change with maternal sensitivity to infant feedback in the context of interaction. In this study, each mother watched her infant (located in an adjacent sound booth) on a video screen and talked to him or her through a microphone. The mother believed that her infant could hear her voice and she attempted to make her infant happy through her vocalizations. In reality, the infant could not hear her voice. The mother's ID speech was analyzed in real time for changes in mean pitch. For half of the infant–mother dyads an experimenter surreptitiously positively engaged the infant when the voice analysis revealed a rise in pitch, thereby producing positive reinforcement to the mother for natural higher pitched ID speech. The other half were reinforced for lower pitched ID speech. Mothers raised their pitch significantly more in the former than the latter condition, illustrating that the pitch of ID speech is dynamically affected by feedback from the infant.     

Predisposing Factors for Elevated Restricted and Repetitive Behavior in Typically Developing Toddlers

Little is known about the relation between levels of restricted and repetitive behavior (RRB) in infants and parent factors. The present study investigated maternal and psychosocial factors (depressive symptoms, socio‐economic status, social support) and mother–infant engagement factors (mind‐mindedness, sensitivity, and infant–mother attachment security) as predictors of children's RRB at age 26 months in a sample of 206 mothers and children. Maternal depressive symptoms predicted levels of sensory and motor repetitive behavior and rigid, routinized, and ritualistic repetitive behavior. Lower socioeconomic status also predicted independent variance in children's sensory and motor repetitive behavior. The relations between maternal depressive symptoms and both types of RRB were not mediated through observational measures of maternal sensitivity or mind‐mindedness at 8 months, or attachment security at 15 months. The results are discussed in terms of whether stress regulation, self‐stimulation, and genetic susceptibility can help explain the observed link between maternal depressive symptoms and RRB in the child.     

Urgent engagement in 9/11 pregnant widows and their infants: Transmission of trauma

The potential effects of maternal trauma on mother–infant interaction remain insufficiently studied empirically. This study examined the effects of the September 11, 2001, trauma on mother–infant interaction in mothers who were pregnant and widowed on 9/11, and their infants aged 4–6 months. Split‐screen videotaped interaction was coded on a one‐second basis for infant gaze, facial affect, and vocal affect; and mother gaze, facial affect, and touch. We examined the temporal dynamics of communication: self‐contingency and interactive contingency of behavior by time‐series methods. We documented heightened maternal and infant efforts at engagement in the 9/11 (vs. control) dyads. Both partners had difficulty tolerating moments of looking away as well as moments of negative behavior patterns. Heightened efforts to maintain a positive visual engagement may be adaptive and a potential source of resilience, but these patterns may also carry risk: working too hard to make it work. A vigilant, hyper‐contingent, high‐arousal engagement was the central mode of the interpersonal transmission of the trauma to these infants, with implications for intervention.     

Maternal Into‐The‐Face Behavior,Shared Attention,and Infant Distress During Face‐to‐Face Play at 12 Months: Bi‐directional Contingencies

We describe a new maternal intrusion behavior, moving a toy or hand “into‐the‐face” of the infant, and we investigate its bi‐directional associations with infant‐initiated shared attention, infant distress, and infant gaze, during mother–infant face‐to‐face play at 12 months. The play was videotaped split‐screen, with infants seated in a high chair. Videotapes were coded on a 1‐sec time base for mother and infant gaze (at partner, toy, both, or gaze away); infant distress; and maternal intrusion behavior, “into‐the‐face.” We defined “infant‐initiated shared attention” as mother and infant looking in the same second at a toy that the infant‐initiated interest in. We documented that maternal into‐the‐face behavior decreased the likelihood of infant‐initiated shared attention, increased the likelihood of infant distress, and decreased the likelihood of infant gazing away. Reciprocally, infant distress and gazing away increased the likelihood of mother into‐the‐face. In moments when the dyad was engaged in infant‐initiated shared attention, mother into‐the‐face was less likely. This work documents bi‐directional contingencies in the regulation of maternal intrusion and infant behavior during face‐to‐face play at 12 months. We suggest that mother into‐the‐face behavior disturbs an aspect of the infant's experience of recognition.     

The Interplay Between Tonal Synchrony and Social Engagement in Mother–Infant Interaction

This study explores the relationship between tonal synchrony and maternal‐infant social engagement based on free‐play recordings of 15 mothers and their 3‐month‐old infants in a laboratory setting. Moment‐by‐moment analyses on a microlevel were used to study social engagement and vocal interaction. We analysed and categorized 854 vocalization periods (mother‐only vocalizations, tonal interaction periods, nontonal interaction periods, and mutual silence). Tonal synchrony was analysed in terms of harmonic and pentatonic series based on pitch frequency analyses. Social engagement was microanalyzed in terms of matched and mismatched engagement states. ANOVA‐repeated measures revealed, most importantly, a significant relationship between TIPs and social interaction repair, which indicates the importance of tonal synchrony in the flow of social engagement in mother–infant dyads. Other significant relationships were found between (a) nTIPs/mismatch–mismatch, and, (b) MOV/affect loss. As mentioned in the discussion, the findings are suggestive for clinical applications (e.g., music therapy) and warrant further research.     

Gaze Behaviors of Preterm and Full‐Term Infants in Nonsocial and Social Contexts of Increasing Dynamics: Visual Recognition,Attention Regulation,and Gaze Synchrony

Although research has demonstrated poor visual skills in premature infants, few studies assessed infants’ gaze behaviors across several domains of functioning in a single study. Thirty premature and 30 full‐term 3‐month‐old infants were tested in three social and nonsocial tasks of increasing complexity and their gaze behavior was micro‐coded. In a one‐trial version of the visual recognition paradigm, where novel stimuli were paired with familiar stimuli, preterm infants showed longer first looks to novel stimuli. In the behavior response paradigm, which presented infants with 17 stimuli of increasing complexity in a predetermined “on‐off” sequence, premature infants tended to look away from toys more during presentation. Finally, during mother–infant face‐to‐face interaction, the most dynamic interpersonal context, preterm infants and their mothers displayed short, frequent episodes of gaze synchrony, and lag‐sequential analysis indicated that both mother and infant broke moments of mutual gaze within 2 sec of its initiation. The propotion of look away during the behavior response paradigm was related to lower gaze synchrony and more gaze breaks during mother–infant interactions. Results are discussed in terms of the unique and adaptive gaze patterns typical of low‐risk premature infants.
