A Cohort Study of Relations Among Caregiver-Infant Co-Occupation and Reciprocity.

Co-occupation is the mutual engagement of two people in a shared occupation. Recent research has investigated co-occupational activities during sensitive periods to inform clinical practice. However, there remains a dearth of applied research to bridge gaps between research and practice within salient co-occupational relationships between caregivers and infants. The study applied co-occupational constructs of physicality, emotionality, and intentionality within caregiver-infant dyads across infancy. These constructs were examined in relation to caregiver-infant reciprocity in other domains (i.e., language, motor, and affective) to determine the overlapping features of reciprocal co-occupation with established aspects of reciprocity. Results suggest that as infants transitioned into toddlerhood and became more mobile and intentional in behavior, there were observable changes in caregiver-infant reciprocity. Caregiver utterances, affect, touch, and co-occupation were significantly related within and across time, highlighting the need for more studies to disentangle these relations in reference to infant development.
