Sažetak
Some children with an idiopathic articulation disorder have poor phonemic discrimination abilities (PDA) which can be due to a central hearing disorder. Literature suggests cortical localization of the disturbances, although the subcortical level is not excluded. The auditory brain-stem response (ABR) technique was used to test 30 boys (6-7 years old) with an articulation disorder and poor PDA (group 1) and the ABR results compared with those obtained in children with articulation disorders but good PDA and children with correct articulation (groups 2 and 3). Statistical analysis found significant differences between group 1 and the other children because of prolonged latencies of waves III and V and interpeak latencies I-III and I-V, compared with the other children. The average ABR in group 1 had the characteristics of the ABR of a child under the age of 1, whose maturation of response has not fully developed. In conclusion, a poor PDA is not only a result of the cortical dysfunction and the basic problem in these children might be a prolonged conduction time and a too slow processing of auditory stimuli at the level of the lower part of the brain-stem.
