THERAPY PROCEDURES BASED ON MOTOR PLANNING TECHNIQUES WERE DEVELOPED FOR THE TREATMENT OF YOUNG ADULT STUTTERERS. THE SUBJECTS FOR THIS STUDY WERE 24 MALE UNIVERSITY STUDENTS RECEIVING THERAPY FOR STUTTERING. USING RATINGS OF THE SEVERITY OF THEIR OVERT STUTTERING, THE INVESTIGATOR DIVIDED THE SUBJECTS INTO AN EXPERIMENTAL GROUP AND A CONTROL GROUP. SUBJECTS IN THE EXPERIMENTAL GROUP WERE TRAINED IN THE USE OF MOTOR PLANNING TECHNIQUES IN ADDITION TO RECEIVING CONVENTIONAL THERAPY. SUBJECTS IN THE CONTROL GROUP RECEIVED ONLY CONVENTIONAL THERAPY. TAPE RECORDINGS WERE MADE DURING PERIODS OF SPONTANEOUS SPEECH BY THE SUBJECTS AND WHILE THEY READ ALOUD AT THE BEGINNING, MIDDLE, AND END OF THE STUDY. SUBJECTS ALSO COMPLETED THE "STUTTERER'S SELF-RATINGS OF REACTIONS TO SPEECH SITUATIONS" AT EACH OF THESE THREE POINTS IN THE STUDY. AT THE END OF THE STUDY, THREE DOCTORAL CANDIDATES USED A MODIFIED VERSION OF THE "IOWA SCALE FOR RATING SEVERITY OF STUTTERING" TO RATE THE SEVERITY OF RESPONSES ON THE TAPE RECORDINGS. THE RATINGS WERE COMPARED WITH THE SCORES OBTAINED ON THE SELF-RATING INVENTORY. CONCLUSIONS OF THE STUDY INDICATED THAT--(1) A GROUP OF SUBJECTS TRAINED TO USE MOTOR PLANNING TECHNIQUES IN ADDITION TO RECEIVING CONVENTIONAL THERAPY DID SHOW A GREATER REDUCTION IN THE SEVERITY OF THEIR STUTTERING THAN A GROUP OF STUTTERERS WHO RECEIVED ONLY CONVENTIONAL THERAPY, (2) THE MOTOR PLANNING TECHNIQUES DEVELOPED FOR USE IN THIS STUDY CAN BE USED TO HELP YOUNG ADULT STUTTERERS FORM, CONSTRUCT, AND EVOLVE MOTOR PLANS DESPITE THE PRESENCE OF ANTICIPATION-ANXIETY. THEREFORE, THESE TECHNIQUES WERE FELT TO CONSTITUTE A SET OF THERAPY PROCEDURES USEFUL TO PROFESSIONAL WORKERS. THE INVESTIGATOR CAUTIONED THAT THESE CONCLUSIONS SHOULD BE REGARDED AS TENTATIVE IN VIEW OF THE SMALL SAMPLE OF SUBJECTS AND THE LACK OF SIGNIFICANT BETWEEN-GROUP DIFFERENCES. (WB)
