Maternal touch in object- and nonobject-oriented play interactions: A longitudinal study at 7 and 12 months.

Social touch is a crucial part of how mothers interact with their infants, with different touch types serving distinct purposes in these exchanges. However, there is still a limited understanding of how mothers' touch behavior adapts to specific interactive tasks, particularly throughout infancy. To address this gap, we observed mother-infant dyads at 7 and 12 months during three structured social play tasks: (a) play with objects, (b) play without objects, and (c) play with a difficult object.

Turn-taking in free-play interactions: A cross-sectional study from 3 to 5 years.

Turn-transition timing in childhood has been examined by measuring response latency - that aggregates gap and overlap duration - in turn-transitions contingent to specific semantic categories. This contrasts with studies in infancy where the whole spectrum of temporal contingent vocalizations are examined, and gap and overlap duration is analyzed independently. We propose using the latter approach to investigate the continuities between infancy and childhood.

Observational measures of caregiver's touch behavior in infancy: A systematic review.

The caregiver's touch behavior during early infancy is linked to multiple developmental outcomes. However, social touch remains a challenging construct to operationalize, and although observational tools have been a gold standard for measuring touch in caregiver-infant interactions, no systematic review has been conducted before. We followed the PRISMA guidelines and reviewed the literature to describe and classify the main characteristics of the available observational instruments.

The effect of play task on maternal touch patterns when interacting with their 12 months-old infants: An exploratory study.

Multiple studies have demonstrated the critical role of touch in human development and the impact of mother's tactile input for an infant's well-being. However, the literature lacks a detailed description of maternal touch behavior during play tasks. Our study examined maternal touch patterns during mother-infant interactions.
