Abstract Details

1973, Doctor of Philosophy (Ph.D.), Bowling Green State University, Communication Disorders.
The purpose of this study was to provide additional information concerning the relationship between speech sound discrimination, or auditory feedback, and oral stereognosis, or tactual and kinesthetic feedback, and their influences upon articulation. One hundred and twenty children were divided into two age groups; 6.5 to 8.5 years and l0.5 to l2.5 years. They were further divided into a control and experimental group based upon their performance on the Templin-Darley Articulation Screening Test. Those individuals in the control group had "normal" speech while those in the experimental group had either "mild" or "severe" articulation defects. Tne Goldman-Fristoe-Woodcock Test of Auditory Discrimination was used to assess speech sound discrimination (SSD) performance and the 20 forms standardized by the National Institute of Dental Research were used to assess oral stereognostic (OS) performance. Regarding age level, an analysis of variance (ANOV) revealed: l) no significant difference in SSD performance, between age levels, for either normals or mild articulatory defectives; 2) a significant difference in SSD performance, between age levels, for the severe articulatory defectives; and 3) a significant difference in OS performance, between age levels, at all levels of articulation proficiency. Regarding articulation proficiency for the younger group, the ANOV revealed: l) no significant difference in either SSD or OS performance between the normals and mild articulatory defectives; and 2) a significant difference in both SSD and OD performance between the normal and mild articulatory defective children and the severe articulatory defectives. Regarding the older group's articulation proficiency, the ANOV revealed: l) no significant difference in SSD performance between any of the levels of articulation proficiency; 2) no significant difference in OS performance between the normals and mild articulatory defectives; and 3) a significant difference in OS performance between the normal and mild articulatory defective children and the severe articulatory defectives. The results of this study support the hypothesis that speech production is a servo-system and depending upon the individual's age, relies upon sensory feedback information from the auditory and/or tactual and/or kinesthetic feed­back systems, and that deficiencies in one or more of these feedback systems may result in articulation defects.
