Relationship between Phonological Disorder and Temporal Resolution

Introduction: Temporal resolution is defined as the ability of the auditory system detects when two successive auditory events occur and prevent them from being detected as a single event. Important skill in the language acquisition process.

Objectives: To analyze the data of phonological sample of children with phonological disorders and the findings of auditory processing random gap detection test (RGDT).

Methods: This is a study of the quantitative and descriptive, with analysis of secondary data collected from VALDEF Data Bank (FAPERGS—Case No. 0,904,179 and CNPq—Process No. 483886/2010-6). The database is composed of 130 children, of which 51 have the test of auditory processing RGDT, this being the study sample.

Results: According to preliminary results, 45 subjects obtained results expected for their ages. Six subjects showed altered results with thresholds higher than expected for the test, where one of them presented a mild severity phonological disorder, four had moderate severe, and one had severe degree.

Conclusion: Being the RGDT a test that evaluates temporal resolution and that disorders in this capacity may result in difficulties to identify small variations in speech acoustic and hence difficulty in producing a correct way speech sounds, it is important to relate the phonological disorder with auditory processing, considering that more than half of the sample is altered in children with high degrees of unintelligible speech.
