“…During infancy, a superordinate‐to‐basic‐level shift in category development has reliably been observed across experimental paradigms: Between 2 and 4 months of age with paradigms based on visual fixation (Arterberry & Bornstein, ; Quinn & Johnson, ), between 6 and 12 months with object examination tasks (Pauen, ), and between 18 and 30 months with sequential touching tasks (Bornstein & Arterberry, ; Mandler, Bauer, & McDonough, ). Although few studies have investigated the development of A–I categorization within this developmental timetable, some evidence using the sequential touching procedure suggests that A–I categorization emerges between 14 and 18 months of age (Rostad, Yott, & Poulin‐Dubois, ), that is, around the same time, superordinate‐level categories have also been shown to emerge with this procedure (18 months: Mandler et al ., ; between 12 and 18 months: Bornstein & Arterberry, ).…”
