Abstract

INTRODUCTION: nowadays, several researches strive to explain which are the causes of reading disorders. Some of them already show that phonological abilities are strictly related to the children’s good performance during the alphabetisation phase. However, the great existing question is what is behind the difficulties involving this ability. One of the hypothesis would be a deficit involving the auditory temporal processing. AIM: to characterise the performance of children with reading disorders in auditory temporal processing and in phonological awareness tests, comparing to a control group. METHOD: 60 children from 9 to 12 years of age were evaluated; 27 belonged to the control group and 33, to the study group. An adaptation of the American test “Repetition Test" was developed, comprising four tests of frequency discrimination and ordering and four tests of duration discrimination and ordering. RESULTS: children with reading disorders presented significant differences when compared to the control group regarding the phonological awareness and the auditory temporal processing tests. Furthermore, the variables stimuli duration and type of task were more sensitive in the study group, for tests involving frequency. A correlation was found only between the performances in the reading and the phonological awareness tests for both groups. CONCLUSION: Children with reading disorders present worse performance when compared to the control group for all tests. It can not be affirmed that there is a direct relation between the poor performance in the auditory temporal processing tests and the phonological awareness abilities, or even reading. (AU)
