a relational approach that emphasizes bidirectional influences between a mother and infant, characterizes the ability of a dyad to jointly structure biobehavioral developments of an infant through repeated experiences across the first months of life.

describes the degree to which physiological reactivity and regulation for a mother and her infant are related from moment-to-moment. Parallel activation of stress physiology (i.e., positive attunement) occurs when increases, and decreases, of stress reactivity are mirrored between members of a dyad. Mother-infant dyads also exhibit patterns of inverse activation (i.e., negative attunement) in which increases in reactivity by one member of the dyad are matched by decreases in the other member, or they may show unrelated physiological activation.

Biobehavioral synchrony, a human-specific process of social coordination, begins with an infant’s first social interactions with parents; during these brief, repetitive-rhythmic exchanges, infants learn to give salience to social cues, excercise flexibility of social response, and practice mutuality as a pathway to social life.

The coordination of nonverbal social signals provides a template for the coordination of physiological processes during social interactions. Human biobehavioral synchrony is stable over time, expanding in complexity and mutuality, and extends across human affiliative bonds and symbolic attachments (@Feldman2021-eh, p. 157)

we propose defining synchrony as a dynamic and reciprocal adaptation of the temporal structure of behaviors and shared affect between interactive partners

(@Leclere2014-yz, p. 1)

In the field of mother-child interactions, the dynamic and reciprocal adaptation of the temporal structure of behaviors between interactive partners defining synchrony implies the following: (i) behaviors include verbal and non-verbal communicative and emotional behaviors (e.g., gestures, postures, facial displays, vocalizations, and gazes). (ii) Synchronous interactions entail coordination between partners and intermodality. Caregivers and their children are able to respond to each other using different modalities starting from birth, Thus, synchrony differs from mirroring or the chameleon effect. Instead, synchrony describes the intricate dance that occurs during short, intense, playful interactions; it builds on familiarity with the partner’s behavioral repertoire and interaction rhythms; and it depicts the underlying temporal structure of highly aroused moments of interpersonal exchange that are clearly separated from the stream of daily life

(@Leclere2014-yz, p. 3)

Synchrony can therefore be defined as the temporal coordination of micro-level relational behaviors into patterned configurations that become internalized and serve to shape infant development over time and repeated experience

(@Leclere2014-yz, p. 4)

Synchrony is not an all or nothing concept; rather, it may be more valid to think about dyadic interactions as approaching or moving away from synchrony

(@Leclere2014-yz, p. 24).

All studies that focus on child development demonstrate a link between synchrony and attachment, on one hand, and child cognitive and behavioral development, on the other

(@Leclere2014-yz, p. 24)

the lack of common evaluation methods in the study of synchrony may introduce bias in the interpretation and comparison of study results between studies
