Examined cultural variation in management of attention by 14- to 20-month olds and caregivers from Guatemalan Mayan community and middle-class community of U.S. European-descent families. Found that Mayan caregivers and toddlers were more likely to attend simultaneously to spontaneously occurring competing events than were U.S. caregivers and toddlers, who were more likely to alternate attention between competing events.
