EFFECTS OF SPEECH IMPROVEMENT ON ARTICULATORY SKILLS IN INSTITUTIONALIZED RETARDATES: II.

The article focuses on the speech improvement program conducted to mentally retarded individuals in the U.S. The program was administered to 40 retarded subjects from the Fort Wayne State Hospital and Training Center for three weeks per sound of a 28-week period. It emphasized consonantal presentation in the initial, final and medial positions, phonetic placement, and auditory training with the use of the overhead projector, "Talking Time" filmstrips and Language Master. The study revealed that the presentation of a speech improvement program to institutionalized groups of retardates did not provide significant treatment effects.
