Effects of time between stimuli on the relationship of speech-sound discrimination skills to consistency of correct production of [s] and [r].
In this study, the relationship between consistency of correct production of [s] and [r] and ability to discriminate between speech sounds separated by three different time intervals is examined. Thirty-six children representing first-grade normal and [s] and [r] defective speakers served as subjects. Each subject listened to tapes of pairs of vowel-consonant-consonant-vowel bisyllables under each of three conditions: (1) 0.25 sec between bisyllables; (2) 2.0 sec between bisyllables; and (3) 10.0 sec between the bisyllables in each pair. The subjects' task was to determine whether the bisyllables in each pair were the same or different. Results of the statistical analyses indicated that the relationships which emerged were a function of the specific error sounds and the time between the stimuli to be discriminated. The findings are related to previous investigations of speech-sound discrimination skills in articulatory defective children.
