Abstract: The purpose of this investigation was to explore the manner in which 15 individuals with Down's syndrome deviated in rhythmic beat responses from a musical stimulus produced by a computer. Subjects ranged in age from 17-46 and had a mean WAIS Full Scale IQ of 57. A reference group of five non—retarded individuals provided comparison data. Measured were: (1) the anticipation and delay of the time interval between beat responses; (2) the interval of time between eac3a beat response in relation to the tempo of the musical example; and (3) a subject's beat intervals (demonstration of tempo) in relation to that subject's beat deviations from the computer beat. A custom-designed Commodore-64 computer program was utilized which contained components for music-editing, timing of the musical stimulus, recording of subject response, and plotting of derived interval and beat deviation data.
