Developmental changes in infants ’ and mothers’ pathways to achieving joint attention episodes

Publication date: February 2018 Source:Infant Behavior and Development, Volume 50 Author(s): Margaret Loy, Elise Frank Masur, Janet Olson when infants were 13 and 17 months old. Analyses revealed developmental changes in initiative frequencies and in the origins of JA episodes. At 13 months, although infants’ less sophisticated object-only initiatives (IObj) were most frequent, JA episodes most often originated in maternal combined initiatives (IJA), which focused on both object and partner. By 17 months, however, infants’ combined initiatives were most frequent and led to more JA episodes than any other initiative type. Infants with more combined initiatives achieved more JA episodes at both ages and greater 17-month vocabularies.
