Research has shown that the quality of mother-infant interactions, as measured by mother-infant synchrony, is associated with infants' vagal tone, a physiological indicator of emotion regulation. However, little is known about the association between the infant's vagal tone and the quality of father-infant interactions. Existing literature…

The present study examined mothers' emotional availability (EA) during daytime free play and bedtime as a mediator of linkages between maternal nighttime sleep and infant-mother attachment. Participants included 153 mothers (85% White) with infants (53% female). When infants were 1, 3, 6, 9, and 12 months, maternal sleep was assessed using…

We compared maternal speech in interactions of mothers with their firstborn dizygotic twin and singleton infants. Nine twins and nine singletons were video-recorded at home in spontaneous face-to-face interactions with their mothers, from the 2nd to the 6th month. Continuous micro-analysis revealed that there are more quantitative and qualitative…

Family systems research has identified two key processes (spillover and compensatory), linking interparental relationship quality to the parent-child relationship. However, previous research has focused on the parent as the sole initiator and had not often considered the role of the child in these processes. The present study adds to the…

Emotion regulation (ER) is a source of risk and resilience for psychological development and everyday functioning. Despite extensive research on various early contextual predictors of child ER capacity, few studies have integrated them into the same study. Therefore, our longitudinal study investigated the joint and independent contributions of…

This theoretical article aims to create a conceptual framework for future research on digital methods for assessing cognition in children through estimating shared intentionality, different from assessing through behavioral markers. It shows the new assessing paradigm based directly on the evaluation of parent-child interaction exchanges…

The study evaluated the relationship between maternal anxiety, depression and parenting stress, and maternal mind-mindedness, styles of interaction, and mother-infant emotion regulation. At infant age 3 months, EPDS, STAI, and PSI-SF were administered to 73 mothers to respectively assess depression, anxiety, and parenting stress; mother-infant…

Child's crying is the stimuli serving the development of a child-parent relationship through evoking child-oriented and parent-oriented parental reactions. Individual differences in parental reactions to crying have been partly explained by parental and child's temperament. We conducted two studies to verify the predicting effects of temperamental…

Infant-mother behavioral synchrony is thought to scaffold the development of self-regulation in the first years of life. During this time, infants' and mothers' physiological regulation may contribute to dyadic synchrony and, in infants, dyadic synchrony may support infants' physiological regulation. Because the sympathetic nervous system (SNS)…

I investigated the emotional coordination (matching, synchrony, completion and attunement) between infant and paternal facial expressions of emotion in the course of paternal questions addressed to infants during their spontaneous dyadic interaction. Eleven infant-father dyads were observed during their natural interactions at home from the second…

This prospective longitudinal study examined how maternal prenatal substance use disorder (SUD) and early mother-infant interaction quality are associated with child social cognition (emotion recognition and mentalization) at school age. A sample of 52 poly-substance-using mothers receiving early interventions and 50 non-users, along with their…

The study examined the effectiveness of PRERAYMI (Promoting Responsiveness Emotion Regulation and Attachment in Young Mothers and Infants) attachment-based intervention programme aimed at adolescent mother-infant dyads. The intervention used video-feedback and developmental guidance to promote maternal mind-mindedness and sensitivity. 32…

Electroencephalogram (EEG) asymmetry has been widely studied across the lifespan, with multiple studies conducted in infancy. However, few have investigated frontal EEG asymmetry in the context of emotional-eliciting tasks, controlling for baseline to focus on an experimental episode response. The present study was designed to address this gap in…

Close observation of the interactions between a traumatised mother and her infant son provides information on the modes of transmission of psychic trauma in the mother-infant dyad. Following the presentation of a current literature review on the theme, the subject of "radioactive residue" and counter-transference in the transmission of…

This study presents, for the first time, (a) the analysis of the modern literature on the reciprocal impact of emotional arousal and interactional synchrony that creates the synergy of this tandem increasing group productivity; (b) the empirical results of 10 online experiments with 41 dyads. These online experiments in different languages found a…
