Eighteen moderately mentally retarded adults, 20 nonretarded elementary age children, and 20 nonretarded adults were exposed to three conditions of an auditory detection task (location, meaning, and a combination of both).

Evaluates the discrimination of signal and silence duration in six-month-old infants, children aged 5 1/2 years, and adults. Results show that infants discriminated duration changes of 20 milliseconds or greater, children discriminated 15 milliseconds, and adults as few as 10 ms. Findings are consistent with other research in revealing age-related…
