Delayed Judgment Speech-Sound Discrimination and /r/ or /s/ Articulation Status and Improvement

Abstract

A delayed judgment test of speech-sound discrimination was correlated with measures of articulation status and articulation improvement with training in two groups of subjects, an /r/ group and an /s/ group. While the discrimination measures were reliable and internally consistent, discrimination-articulation correlations were low. Several possible psychometric explanations for the nonsignificant results are ruled out, and subject and task variables that might interfere with children’s performance on discrimination measures are discussed.
