Five children who had participated 15–19 times between 6–40 weeks of age in a study of the perception of auditory space returned to the laboratory two years later. The original experimental sequence, which entailed trials in both light and darkness, was carried out along with several additional memory probes. Five control subjects, age, and sex mates who had not previously participated, also experienced the test procedure. Behavior was videotaped and recorded by two observers, and the control and experimental groups were compared on a series of measures. Several measures provide indications that the 2-year-olds remembered what they did in the laboratory two years before; specifically, they retained memory for early action sequences. The findings are of particular interest because a transition from preverbal to verbal functioning marks this 2-year period of development. |
