Abstract
This study investigates infants' neural and behavioral responses to maternal ostensive signals during naturalistic mother-infant interactions and their effects on object encoding. Mothers familiarized their 9- to 10-month-olds (N = 35, 17 females, mainly White, data collection: 2018–2019) with objects with or without mutual gaze, infant-directed speech, and calling the infant's name. Ostensive signals focused infants' attention on objects and their mothers. Infant theta activity synchronized and alpha activity desynchronized during interactions compared to a nonsocial resting phase (Cohen' d: 0.49–0.75). Yet, their amplitudes were unrelated to maternal ostensive signals. Ostensive signals did not facilitate object encoding. However, higher infant theta power during encoding predicted better subsequent object recognition. Results strengthen the role of theta-band power for early learning processes.
期刊介绍：
As the flagship journal of the Society for Research in Child Development (SRCD), Child Development has published articles, essays, reviews, and tutorials on various topics in the field of child development since 1930. Spanning many disciplines, the journal provides the latest research, not only for researchers and theoreticians, but also for child psychiatrists, clinical psychologists, psychiatric social workers, specialists in early childhood education, educational psychologists, special education teachers, and other researchers. In addition to six issues per year of Child Development, subscribers to the journal also receive a full subscription to Child Development Perspectives and Monographs of the Society for Research in Child Development.
