Caregivers' goals influence their interactions with their children. In this preregistered study, we examined whether directing parents to "teach" their baby versus "learn" from their baby influenced the extent to which they engaged in intrusive (e.g., controlling, adult-centered rather than child-centered), sensitive, warm, or…

As infants interact with the object world, they generate rich information about object properties and functions. Much of infant learning unfolds in the presence of caregivers, who talk about and act on the objects of infant play. Does mother joint engagement correspond to real-time changes in the complexity and duration of infant object…

This study aimed to investigate how mothers and infants contribute mutually to breastfeeding. The spontaneous interactions of 20 breastfeeding dyads were video-recorded at home, at 2, 4, 6, 9 and 12 months of infants' life. Mothers' and infants' gaze and tactile behaviour, facial expressions of emotion, and dyadic expressions were continuously…

Early mother-infant coordinated interactions play a critical role in infant development. The present study describes the development of the dyadic coordination of vocalization and gaze behavior between mothers and infants over the first year of life. In addition to describing developmental trajectories of behavior, the study contributes to our…

This study captures the possibilities of infants' interactions in a Brazilian Early Childhood Education Centre. It contributes to an increasing number of educational research that is capturing the specificities of how young children use their understandings of context through gestures and verbal forms of language to create meanings as they develop…

Prior studies of mother-infant interaction have generally used a variable-centered approach to associate face-to-face communication with psychosocial outcomes. Herein, we use a person-centered approach to identify clusters of infants who exhibit similar behavioral profiles during face-to-face communication with their mothers. Four infant…

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…

A fundamental question about the development of communication behavior in early life is how infants acquire adaptive communication behavior that is well-suited to their individual social environment, and how the experience of parent-child communication affects this development. The current study investigated how infants develop communication…

The study of infants' interactive style and social stress response to repeated stress exposures is of great interest for developmental and clinical psychologists. Stable maternal and dyadic behavior is critical to sustain infants' development of an adaptive social stress response, but the association between infants' interactive style and social…

Infants' motor skill development triggers changes in parent-infant interactions, exploration, and play behaviors, particularly during periods of locomotor transitions. We investigated how these transitions reorganized infants' and mothers' explorations of spatial layouts. Thirteen infants and their mothers were followed biweekly from the age of 6…

The study of dyadic interaction plays a major role in infancy research. To advance conceptually informed measurement of dyadic interaction and integration across studies, we examined factor structure of individual parents' and infants' measures and dyadic measures from face-to-face interactions in two samples of 6-month-old infants and…

This research examined the child, parent, and family conditions under which attachment disorganization was related to both level and change in externalizing behavior during preschool among a community sample. Using the ordinary least squares regression, we found that attachment disorganization at 12 months significantly predicted children's…

This study aims to (a) identify and profile groups of infants according to their behavioral and physiological characteristics, considering their neurobehavioral organization, social withdrawal behavior, and endocrine reactivity to stress, and to (b) analyze group differences in the quality of mother-infant interaction. Ninety-seven 8-week-old…

In this article we argue that current theories on socioemotional development during infancy need to be reconceptualized in order to account for cross-cultural variation in caregiver-infant interaction. In line with the cultural-historical internalization theory of emotional development (Holodynski & Friedlmeier, 2006) and the ecocultural model of…

Using electrocardiogram data with 78 six-month-old infants, this study examined the presence or absence of brief orienting bradycardia during the onset of maternal arm-restraint and subsequent differences between infants on behavioral organization during restraint. Results showed that 45 of the infants exhibited brief episodes of bradycardia at…
