Limited effects of pre‐existing maternal antisocial behaviours on infant neurodevelopment: A pilot study

Antisocial behaviour disorders (ABDs) are among the most costly and treatment resistant of all psychiatric syndromes. Select neurodevelopmental abnormalities have been labelled a risk factor for ABDs, but it is unknown if maternal ABDs are associated with early neurodevelopmental abnormalities. This study tested whether infants of ABD mothers had more neurodevelopmental abnormalities than mothers with no psychiatric disorder (ND). Thirty‐nine pregnant women (49% with ABDs; 51% no psychiatric disorder) were recruited from the community. Infant neurodevelopment was assessed at ≤1 and 8 weeks using the Neonatal Behavioural Assessment Scale and at 16 weeks of age using the Bayley Scales of Infant and Toddler Development‐III. There was no significant group difference at ≤8 weeks. At 16 weeks, ABD mothers rated their infants higher on the Adapted Behaviours subscale, specifically on the leisure and self‐directed scales, when corrected for substance use and socio‐economic status. This pilot study found higher maternal ratings of Adapted Behaviours at 16 weeks, which may be due to unrealistic expectations about infant development.

Highlights

• Maternal Antisocial behaviour disorders (ABDs) do not impact early infant neurodevelopment at ≤ 8 weeks old as measured by standardized assessment.
• Mothers with ABDs view their infants at 16 weeks as better adapted than women without any psychiatric disorder.
• Specifically, mothers with ABDs reported their infants as better adapted on the leisure and self‐direction subscales of the Bayley Scales of Infant and Toddler Development‐III. This finding may be due to less knowledge about normal infant adaptive behavior.

     

Linking patterns of infant eye movements to a neural network model of the ventral stream using representational similarity analysis

Little is known about the development of higher-level areas of visual cortex during infancy, and even less is known about how the development of visually guided behavior is related to the different levels of the cortical processing hierarchy. As a first step toward filling these gaps, we used representational similarity analysis (RSA) to assess links between gaze patterns and a neural network model that captures key properties of the ventral visual processing stream. We recorded the eye movements of 4- to 12-month-old infants (N = 54) as they viewed photographs of scenes. For each infant, we calculated the similarity of the gaze patterns for each pair of photographs. We also analyzed the images using a convolutional neural network model in which the successive layers correspond approximately to the sequence of areas along the ventral stream. For each layer of the network, we calculated the similarity of the activation patterns for each pair of photographs, which was then compared with the infant gaze data. We found that the network layers corresponding to lower-level areas of visual cortex accounted for gaze patterns better in younger infants than in older infants, whereas the network layers corresponding to higher-level areas of visual cortex accounted for gaze patterns better in older infants than in younger infants. Thus, between 4 and 12 months, gaze becomes increasingly controlled by more abstract, higher-level representations. These results also demonstrate the feasibility of using RSA to link infant gaze behavior to neural network models. A video abstract of this article can be viewed at https://youtu.be/K5mF2Rw98Is

TOP‐DOWN AND BOTTOM‐UP: THE ROLE OF SOCIAL INFORMATION PROCESSING AND MINDFULNESS AS PREDICTORS IN MATERNAL–INFANT INTERACTION

The cross‐generational transmission of attachment appears to reflect a complex interplay of factors, which have been challenging to identify. The current longitudinal study explored the maternal cognitive model of relationships through language use, maternal mindfulness, and attachment style assessed prenatally, as predictors of maternal response to distress and infant behavior at 6 months’ postpartum. Infant behavior to the mother also was examined to provide an understanding of the evolving relationship. Thirty‐two females were interviewed prenatally regarding social and family experiences. At 6 months’ postpartum, each mother participated in a video‐recorded session where she was asked to teach her infant a developmentally appropriate task. Videos were analyzed using the NCAST Teaching Protocol. Language use prenatally as well as the mindfulness facets (acting with awareness and describing) predicted the mothers’ ability to respond to infant distress, indicating greater attunement. Infant's response to mother and clarity of cues also were predicted by maternal pronoun use. The study highlights the role of internal working models reflective of interpersonal beliefs, cognitive models, and current‐moment awareness in maternal behavior. The effect of maternal language on infant behavior arguably indicates the infant's integration of maternal internal working models.     

Young infants' vocalizations towards mother versus stranger: associations with the infant–mother relationship

Infants' differential vocal response (DVR) towards their mother and a female stranger at 3 months of age has been predominantly investigated as an index of early cognitive functioning. The present study explored the relationship between DVR and different infant and mother indicators of the developing relationship quality in a sample of 23 mother–infant dyads. Mother–infant interactions and stranger–infant interactions were videotaped during home visits when the infants were 3 months old. At the age of 12 months, infants' behaviour was assessed in the Ainsworth's strange situation. In both assessments, mothers noted the infants' behavioural states on 3 successive days. Results revealed a specific relation between DVR and the emotional atmosphere of the early mother–infant interaction. Particularly, DVR was less pronounced in favour of the mother when the mother displayed emotional expressions defined as rejection. DVR is discussed as an index that may indicate both infant emotional engagement and infant cognitive competencies. Copyright © 2005 John Wiley & Sons, Ltd.     

The linkage between infant negative temperament and parenting self‐efficacy: The role of resilience against negative performance feedback

Caring for infants with negative reactive temperament may tax parents' confidence in their caregiving ability, or parenting self‐efficacy (PSE). This may happen in particular in parents who interpret these signals as negative feedback on their performance. To test this hypothesis, 179 first‐time pregnant women were presented a caregiving simulation that provided positive and negative feedback on their attempts to comfort a crying baby. According to their PSE resilience to negative feedback during the task, they were grouped in a high resilient and low resilient group. PSE was followed up at 32 weeks of pregnancy and 3 and 12 months after birth, while perceived temperament of the child was assessed at 3 and 12 months after birth. Results showed that among women with low resilience against negative feedback, perceived negative temperament was negatively associated with PSE at 3 months, whereas no such association was observed among women with high resilience against negative feedback. Implications of the concept of resilience for the study of PSE are discussed.     

婴儿期母亲将心比心对儿童5岁共情的预测:母亲陪伴总时间的调节作用

使用追踪设计，以68对母婴为被试，探讨母亲养育质量、陪伴时间影响儿童共情发展的机制。在婴儿期（9、14个月）评估母亲将心比心并调查母亲每周陪伴婴儿的总时间与母亲参与的互动时间；在儿童5岁时，采用“陌生人假装受伤情境”范式测查儿童共情。结果发现：（1）婴儿期母亲恰当的心理相关评论能够正向预测5岁时儿童的行为共情，而对情绪共情与认知共情的预测则受到婴儿期母亲陪伴总时间的调节：母亲恰当的心理相关评论能够显著正向预测陪伴总时间短的儿童的情绪共情与母亲陪伴总时间长的儿童的认知共情；（2）婴儿期母亲不协同的心理相关评论能够显著正向预测儿童5岁时的认知共情；（3）婴儿期母亲陪伴总时间能够显著正向预测5岁时儿童的情绪共情。     

Maternal and paternal infant-directed speech to girls and boys: An exploratory study

ABSTRACT

We compared systematically the structure and the content of maternal and paternal speech to infant boys and girls while we also investigated the effect of infant’s age. Six girls and five boys were observed in the interaction with their mothers and their fathers (dyads came from the same families) at home from the second to the sixth month after birth at 15- day intervals. Detailed analysis of time revealed that fathers favour systematically the temporal structure of their speech to both girls and boys, while mothers favour boys in infant emotion/attention thematic sequences and girls in infant attention speech. Variations are counterbalanced in the way mothers and fathers respond sensitively to known marked changes in infant- parent communication over the first 6 months of life. These results are discussing in relation to the theory of innate intersubjectivity and the complementary company and care both parents give to developing infant girls and boys.

Are babies sensitive to the context of acute pain episodes? Infant distress and maternal soothing during immunization routines at 3 and 5 months of age

Ninety‐three healthy full‐term Italian infants were observed longitudinally at 3 and 5 months during routine vaccinations. Mothers' behaviour was also observed. Participants were divided into two cohorts depending on procedure of inoculation (the first cohort, n=44, showed more distress; the second cohort, n=49, showed less distress). Results indicate that babies' different levels of behavioural distress correspond to mothers' different soothing strategies. Maternal proximal soothing at 3 months predicts faster infant quieting at 5 months, but concurrent and predictive effects of maternal proximity are apparent only when level of baby distress is not too high. The study confirms the view that young babies are sensitive to the overall context of acute pain episodes, including medical procedure and maternal soothing. Copyright © 2005 John Wiley & Sons, Ltd.
