Mother–child emotion dialogues: the disrupting effect of maternal history of communal sleeping

The study examined associations between mothers’ upbringing background (kibbutz vs. home) and maternal-sensitive guidance of emotional conversations with their preschool children; children’s cooperation and exploration; and the coherence of their conversations. Using a quasi-experimental design, 112 children and their mothers (72 kibbutz raised, 40 home) completed the Autobiographical Emotional Event Dialogue. We hypothesized that maternal kibbutz upbringing would be associated to lower levels of mothers’ sensitive guidance of the conversations, children’s lower cooperation and exploration, and lower overall coherence. Results showed no upbringing-related differences for the mothers, but significant differences were found for the children, with children of kibbutz-raised mothers showing less cooperation and exploration, and lower levels of coherence for these dyads. The role of maternal background in shaping the interaction with their child is discussed.     

Effect of maternal panic disorder on mother–child interaction and relation to child anxiety and child self-efficacy

To determine whether mothers with panic disorder with or without agoraphobia interacted differently with their children than normal control mothers, 86 mothers and their adolescents (aged between 13 and 23 years) were observed during a structured play situation. Maternal as well as adolescent anxiety status was assessed according to a structured diagnostic interview. Results showed that mothers with panic disorder/agoraphobia showed more verbal control, were more criticizing and less sensitive during mother–child interaction than mothers without current mental disorders. Moreover, more conflicts were observed between mother and child dyadic interactions when the mother suffered from panic disorder. The comparison of parenting behaviors among anxious and non-anxious children did not reveal any significant differences. These findings support an association between parental over-control and rejection and maternal but not child anxiety and suggest that particularly mother anxiety status is an important determinant of parenting behavior. Finally, an association was found between children’s perceived self-efficacy, parental control and child anxiety symptoms.     

A meta-analysis of mother–child synchrony in respiratory sinus arrhythmia and contextual risk

Biobehavioral frameworks of attachment posit that mother–child dyads engage in physiological synchrony that is uniquely formative for children's neurobiological, social, and emotional development. Much of the work on mother–child physiological synchrony has focused on respiratory sinus arrhythmia (RSA). However, the strength of the existing evidence for mother–child RSA synchrony during interaction is unclear. Using meta-analysis, we summarized results from 12 eligible studies comprising 14 samples and 1201 children ranging from infancy to adolescence (M_age = 5.68 years, SD = 4.13, range = 0.4–17 years) and their mothers. We found that there was a statistically significant, albeit modest, positive within-dyad association between mother and child fluctuations in RSA. There also was evidence for significant heterogeneity across studies. Less mother–child RSA synchrony was observed in high-risk samples characterized by clinical difficulties, history of maltreatment, or socioeconomic disadvantage. We did not find that mother–child RSA synchrony significantly differed by task context, mean child age, or by epoch length for computing RSA. Collectively, these findings suggest that mother–child dyads show correspondence in their fluctuations in RSA, and that RSA synchrony is disrupted in high-risk contexts. Future directions and implications for the study of parent–child physiological synchrony are discussed.     

The impact of maternal psychopathology on child–mother attachment

This review aims to consider evidence for the impact of maternal psychopathology on the child’s attachment to the mother, and the role of this in mediating the known transmission of developmental and clinical risk to children. The studies reviewed focus on mothers with depression and psychotic disorder. A number of studies (mainly of mothers with depression) demonstrate an association between insecure/disorganised infant attachments and severe maternal psychopathology, whether chronic or current, in the presence of comorbid disorder, maternal insecure or unresolved attachment state of mind, trauma/loss, or low parenting sensitivity. Whether such effects last into middle childhood, however, is unclear. Our understanding of the role of attachment in determining developmental trajectories in this group is at an early stage. Some evidence suggests that attachment may have a role in mediating the intergenerational transmission of internalising and other problems in this group, although the presence of co-occurring contextual risk factors may account for the variability in findings. A multifactorial longitudinal approach is needed to elucidate such factors. However, the current literature highlights which subgroups are likely to be vulnerable and provides an evidence-based rationale for taking an attachment-based approach to intervention in this group.     

Insatiable insecurity: maternal obesity as a risk factor for mother–child attachment and child weight

Childhood obesity has become a rising health problem, and because parental obesity is a basic risk factor for childhood obesity, biological factors have been especially considered in the complex etiology. Aspects of the family interaction, e.g., mother–child attachment, have not been the main focus. Our study tried to fill this gap by investigating whether there is a difference between children of obese and normal weight mothers in terms of mother–child attachment, and whether mother–child attachment predicts child’s weight, in a sample of 31 obese and 31 normal weight mothers with children aged 19 to 58 months. Mother–child attachment was measured with the Attachment Q-Set. We found that (1) children of obese mothers showed a lower quality of mother–child attachment than children of normal weight mothers, which indicates that they are less likely to use their mothers as a secure base; (2) the attachment quality predicted child`s BMI percentile; and (3) the mother–child attachment adds incremental validity to the prediction of child’s BMI beyond biological parameters (child’s BMI birth percentile, BMI of the parents) and mother’s relationship status. Implications of our findings are discussed.     

Hippocampo–cerebellar theta band phase synchrony in rabbits

Hippocampal functioning, in the form of theta band oscillation, has been shown to modulate and predict cerebellar learning of which rabbit eyeblink conditioning is perhaps the most well-known example. The contribution of hippocampal neural activity to cerebellar learning is only possible if there is a functional connection between the two structures. Here, in the context of trace eyeblink conditioning, we show (1) that, in addition to the hippocampus, prominent theta oscillation also occurs in the cerebellum, and (2) that cerebellar theta oscillation is synchronized with that in the hippocampus. Further, the degree of phase synchrony (PS) increased both as a response to the conditioning stimuli and as a function of the relative power of hippocampal theta oscillation. However, the degree of PS did not change as a function of either training or learning nor did it predict learning rate as the hippocampal theta ratio did. Nevertheless, theta band synchronization might reflect the formation of transient neural assemblies between the hippocampus and the cerebellum. These findings help us understand how hippocampal function can affect eyeblink conditioning, during which the critical plasticity occurs in the cerebellum. Future studies should examine cerebellar unit activity in relation to hippocampal theta oscillations in order to discover the detailed mechanisms of theta-paced neural activity.     

Correlates of child–father and child–mother attachment in the preschool years

The increase in fathers’ involvement in childrearing, particularly beyond infancy, warrants research exploring factors influencing the quality of child–father attachment relationships, and the impact of these relationships on children’s social development. The current investigation explored various correlates of preschoolers’ child–father attachment security to both parents, including contextual factors (i.e., socioeconomic status, child temperament, parenting stress), parental play sensitivity, and child social adaptation. Participants included 107 preschool-aged children (59 girls; M = 46.67 months, SD = 8.57) and their fathers and mothers. Results revealed that both mothers’ and fathers’ play sensitivity were associated with child attachment security after controlling for different contextual factors. Furthermore, the magnitude of the association between child conduct problems and child–father attachment insecurity was stronger than the corresponding association with child–mother attachment insecurity. Findings provide important information on caregiving factors associated with child–father attachment security in the preschool years and the importance of this bond to children’s social adaptation.     

Poke and pop: Tactile–visual synchrony increases visual saliency

The majority of studies investigating interactions between vision and touch have typically explored single events, presenting one object at a time. The present study investigates how tactile–visual interactions affect competition between multiple visual objects in more dynamic cluttered environments. Participants searched for a horizontal or vertical line segment among distractor line segments of various orientations, all continuously changing color. Search times and search slopes were substantially reduced when the target color change was accompanied by a tactile signal. These benefits were observed even though the tactile signal was uninformative about the location, orientation, or color of the visual target. We conclude that tactile–visual synchrony guides attention in multiple object environments by increasing the saliency of the visual event.     

Physiological measures of mother–infant interactional synchrony

Mother–infant interactional synchrony has been hypothesized to be crucial for the development of many key neurodevelopmental behaviors in infants, including speech and language. Assessing synchrony is challenging because many interactive behaviors may be subtlety, if at all, observable in overt behaviors. Physiological measures, therefore, may provide valuable physiological/biological markers of mother–infant synchrony. We have developed a multilevel measurement platform to assess physiological synchrony, attention, and vocal congruency during dynamic face-to-face mother–infant interactions. The present investigation was designed to provide preliminary data on its application in a group of 10 mother–infant dyads (20 subjects) ranging in age from 7 to 8.5 months at the time of the experimentation. Respiratory kinematics, heart rate, and vocalization were recorded simultaneously from mothers and infants during nonstructured, face-to-face interactions. Novel statistical methods were used to identify reliable moments of synchrony from cross-correlated, mother–infant respiration and to tag infant attention from heart rate deceleration. Results revealed that attention, vocal contingency, and respiratory synchrony are temporally clustered within the dyad interaction. This temporal alignment is consistent with the notion that biological synchrony provides a supportive platform for infant attention and mother–infant contingent vocalization.     

Temporal frequency characteristics of synchrony–asynchrony discrimination of audio-visual signals

Temporal synchrony is a critical condition for integrating information presented in different sensory modalities. To gain insight into the mechanism underlying synchrony perception of audio-visual signals we examined temporal limits for human participants to detect synchronous audio-visual stimuli. Specifically, we measured the percentage correctness of synchrony-asynchrony discrimination as a function of audio-visual lag while changing the temporal frequency and/or modulation waveforms. Audio-visual stimuli were a luminance-modulated Gaussian blob and amplitude-modulated white noise. The results indicated that synchrony-asynchrony discrimination became nearly impossible for periodic pulse trains at temporal frequencies higher than 4 Hz, even when the lag was large enough for discrimination with single pulses (Experiment 1). This temporal limitation cannot be ascribed to peripheral low-pass filters in either vision or audition (Experiment 2), which suggests that the temporal limit reflects a property of a more central mechanism located at or before cross-modal signal comparison. We also found that the functional behaviour of this central mechanism could not be approximated by a linear low-pass filter (Experiment 3). These results are consistent with a hypothesis that the perception of audio-visual synchrony is based on comparison of salient temporal features individuated from within-modal signal streams.     

Social media use and parent–child relationship: A cross-sectional study of adolescents

We examined the association between social media use and parent–child relationship quality and tested whether this association is independent of total screen time. Data on 9,732 students (48.4% female) aged 11–20 years were obtained from a provincially representative school-based survey. Heavy use of social media (daily use of more than 2 hr) was associated with greater odds of negative relationships between mother–daughter (odds ratio [OR] = 1.79; 95% confidence interval [CI]: 1.27–2.52), father–daughter (OR = 1.56; 95% CI: 1.16–2.09), father–son (OR = 2.19; 95% CI: 1.58–3.05) but not mother–son (OR = 1.17; 95% CI: 0.88–1.55). Results were similar after further adjusting for total screen time. There were no significant associations between regular use of social media (2 hr or less) and parent–child relationships. These findings suggest that heavy use of social media is associated with negative parent–child relationships. Longitudinal research is necessary to disentangle the pathways between social media use and the parent–child relationship.     

It takes two to talk: Longitudinal associations among infant–mother attachment,maternal attachment representations,and mother–child emotion dialogues

Research on the attachment-dialogue link has largely focused on infant–mother attachment. This study investigated longitudinal associations between infant–mother attachment and maternal attachment representations and subsequent mother–child emotion dialogues (N = 50). Maternal attachment representations were assessed using the Adult Attachment Interview when children were 3 months, infant–mother attachment was assessed using the Strange Situation Procedure at 13 months, and mother–child emotion dialogues were assessed using the Autobiographical Emotional Events Dialogue at 3.5 years. Consistent with past research, the three organized categories of infant–mother attachment relationships were associated with later mother–child emotion dialogues. Disorganized attachment relationships were associated with a lack of consistent and coherent strategy during emotion dialogues. Autonomous mothers co-constructed coherent narratives with their children; Dismissing and Preoccupied mothers created stories that were less narratively organized. Although the Unresolved category was unrelated to classifications of types of mother–child discourse, mothers’ quality of contribution to the dialogues was marginally lower compared to the quality of their children’s contributions to the emotion discussion. Secure children showed highest levels of child cooperation and exploration. Autonomous mothers displayed highest levels of maternal sensitive guidance during emotion dialogues. We provide preliminary evidence for role reversal in dialogues between Preoccupied and Unresolved mothers and their children.     

Influence of oxytocin on parenting behaviors and parent–child bonding: A systematic review

Oxytocin (OT) plays a pivotal role in early parent–child relationship formation and bonding that is critical for the social, cognitive, and emotional development of the child. Therefore, this systematic review aims to consolidate all available evidence regarding the associations of parental OT concentration levels with parenting behavior and bonding within the past 20 years. A systematic search was conducted in five databases from 2002 to May 2022, and 33 studies were finalized and included. Due to the heterogeneity of the data, findings were presented narratively based on the type of OT and parenting outcomes. Current evidence strongly suggests that parental OT levels are positively related to parental touch and parental gaze and affect synchrony and observer-coded parent–infant bonding. No gender difference in OT levels was observed between fathers and mothers, but OT strengthens affectionate parenting in mothers and stimulatory parenting in fathers. Child OT levels were also positively associated with parental OT levels. Family and healthcare providers could encourage more positive touch and interactive play between parent and child to strengthen parent–child relationships.     

A Step Beyond Maternal Depression and Child Behavior Problems: The Role of Mother–Child Aggression

Previous researchers have identified problematic mother–child interaction patterns as a potential pathway through which maternal depressive symptoms impact child behavior problems, but could not establish the temporal precedence of these associations. This longitudinal study investigated mother–child aggression as a mechanism in the association between maternal depressive symptoms that occurred during infancy and subsequent child behavior problems among high-risk families. Two hundred thirty-four socioeconomically disadvantaged families were recruited from neighborhoods with high rates of family violence. During infancy (12–18 months), early childhood (4 years), and middle childhood (6 years), mothers reported their current depressive symptoms and use of psychological and physical aggression with their child. During early and middle childhood, mothers reported their children’s behavior problems. Using path analyses, a temporal process was identified in which mother–child aggression during early childhood mediated the association between maternal depressive symptoms during infancy and higher levels of externalizing behavior problems during middle childhood. Mother–-child aggression did not mediate the association between maternal depressive symptoms during infancy and higher levels of internalizing behavior problems during middle childhood. Early maternal depressive symptoms that occur during infancy are important risk factors for subsequent mother–child aggression, which, in turn, contributes to more child externalizing behavior problems. Therefore, screening mothers for depressive symptoms and providing intervention and prevention services to improve mother–child interactions may be crucial to preventing the exacerbation of externalizing behavior problems. Additional research is needed to identify pathways to child internalizing behavior problems.
