โœฆ Synopsis

We previously reported that the latency of responding to a memory prime in a reactivation procedure decreases between 3 and 6 months of age. The present study extended this analysis through the first year of life. In this study, 6-, 9-, and 12-month-olds learned an operant task. One week after they had forgotten it, infants were exposed to a component of the original event as a memory prime and were tested after different delays for evidence of retention. Although the interval between the original event and priming increased linearly with agefrom 3 weeks at 6 months to 9 weeks at 12 months, the latency of responding after priming decreased linearly with age-from 1 hr at 6 months to 0-1 s at 12 months. The latency of responding after priming was not task-specific; at 6 months, it was identical in two different tasks. These results provide additional evidence that priming in reactivation studies with infants is the same automatic, perceptual identification phenomenon as repetition priming in studies with adults.

In two experiments with 260 infants between 2 and 12 months of age, we examined how differences between the conditions of encoding and retrieval affect retention. Initially, 9- and 12-month-olds were tested with a different cue (Experiment 1) or in a different context (Experiment 2) after delays spa

This research documents the development of long-term memory in human infants from 2 months through the end of the first year-and-a-half of life. In the initial study phase, we trained 6-to 18-month-old human infants in an operant task and tested them after increasing delays until they exhibited no r

The short-duration response, long-duration response, and dyskinetic response to levodopa change during long-term levodopa therapy. How these responses evolve, and which changes contribute to the emergence of motor fluctuations, remain unclear. We studied 18 subjects with Parkinson's disease before t

Data on activity states were collected from 29 group-housed capuchin monkey (Cebus apella) infants for 3 h each week from birth to 11 weeks of age. The amounts of time spent in sleeping/drowsy, alert-quiet, and alert-active states were measured in these subjects. Videotaped observations of these inf
