Abstract

Severely hearing impaired individuals typically exhibit speech that is unintelligible and systematic instruction in speech has not effectively alleviated all of the misarticulations found in the speech of these individuals. Behavior modification is a promising development which has meaningful application to the modification of defective articulation by hearing impaired children.

The purpose of this study was to as certain the feasibility of implementing a specific program of stimulus manipulation to alter the articulation of the |TS| phoneme as uttered by one severely hearing impaired individual. The training program was structured in a sequence of four operant training conditions. Pre-training tests, training tasks, intra-training probe tests, post-training tests, stimulus generalization tests, and retention tests were administered.

As a result of this investigation, it was concluded that the use of a behavior modification training program appears to be an effective method by which the articulation of a hearing impaired individual may be modified.
