Abstract
Introduction Behavioral tests of auditory processing have been applied in schools and highlight
the association between phonological awareness abilities and auditory processing,
confirming that low performance on phonological awareness tests may be due to low
performance on auditory processing tests.
Objective To characterize the auditory middle latency response and the phonological awareness
tests and to investigate correlations between responses in a group of children with
learning disorders.
Methods The study included 25 students with learning disabilities. Phonological awareness
and auditory middle latency response were tested with electrodes placed on the left
and right hemispheres. The correlation between the measurements was performed using
the Spearman rank correlation coefficient.
Results There is some correlation between the tests, especially between the Pa component
and syllabic awareness, where moderate negative correlation is observed.
Conclusion In this study, when phonological awareness subtests were performed, specifically
phonemic awareness, the students showed a low score for the age group, although for
the objective examination, prolonged Pa latency in the contralateral via was observed.
Negative weak to moderate correlation for Pa wave latency was observed, as was positive
weak correlation for Na-Pa amplitude.
