Adult-infant early dyadic interactions have been extensively explored by developmental psychologists. Around the age of 2 months, infants already demonstrate complex, delicate and very sensitive behaviors that seem to express their ability to interact and share emotions with their caregivers. This paper presents 3 pilot studies of parent-infant dyadic interaction in various set-ups. The first two present longitudinal data collected on two infants aged between 1 and 6 months and their mothers. We analyzed the development of coordination between them, at (...) the motor and at the vocal level. The 3rd pilot study aims to explore interpersonal coordination in both vocal behavior and motor activity for one infant and his mother at 2, 4 and 6 months. These pilot studies however leave a number of questions open concerning developmental changes and infants’ progressive mastery of interaction. We identify areas worth examining and try to tease out specific issues that may help develop new methodological pathways for the study of early naturalistic social interaction. We assume that a continuous, rather than discrete, approach would better capture the changes taking place in the various communicative modalities, while also displaying each dyad’s specificity and the narrative dimension of social engagement between infants and caregivers.

This paper explores how phenomenological notions of rhythm might accommodate a richer description of preverbal infant-caregiver dialogue. Developmental psychologists have theorized a crucial link between rhythm and intercorporeality in the emergence of intersubjectivity and self. Drawing on the descriptions of rhythm in the phenomenology of Maurice Merleau-Ponty, Erwin Straus, Henri Maldiney and Maxine Sheets-Johnstone, the paper emphasizes the role of art and aesthetic processes proposing that they not only be considered as metaphorical or representational aspects of rhythm but as primary (...) resources that can enrich and deepen our understanding of self-emergence and intercorporeality in preverbal infant-caregiver dialogue.

In their first weeks of life preterm infants are deprived of developmentally appropriate stimuli, including their mother’s voice. The current study explores the immediate association of two preterm infant behaviours (open eyes or smiling) with the quality of a mother’s infant-directed speech and singing. Participants are 20 mothers who are asked to speak and sing to their medically stable infants placed in incubators. Eighty-four vocal samples are extracted when they occur in the presence of an infant’s behavioural display and compared (...) with random selections during periods of absence of target behavioural display. The results show that infant-directed maternal voice presents more marked emotional qualities when infants display a behavioural change than when infants are passive and expressionless. Specifically, higher values of mean pitch and maximum sound pressure level, as well as greater variability of these parameters are associated with a behavioural display. (shrink)
