Reciprocity and interactional synchrony

A form of communication between a caregiver and an infant, where each person responds to the other. Think of it like a conversation.

A 1975 study by Brazelton that showed how turn-taking in infant-caregiver interactions is like a dance, with each partner responding to the other's cues.

An extension of reciprocity. Mothers typically notice 2/3 of a baby's alert phases, allowing for more interaction.

This term means 'at the same time.'

The mirroring of behaviors between a baby and their caregiver. Both individuals copy each other's actions.

Feldman's explanation of IS, emphasizing the precise timing and coordination of small social behaviors.

The two main types of social interactions observed between caregivers and infants.

The process of caregivers understanding and responding to their baby's subtle cues, such as facial expressions and gestures.

Reciprocity and Interactional Synchrony are crucial for healthy emotional development. They help build strong bonds between caregivers and infants.
