Correlation between auditory and visual perception in schoolchildren

Purpose: to investigate the correlation between auditory and visual perception by analyzing the variation in visual perception of students with and without Central Auditory Processing Disorder (CAPD). Methods: 26 children (11 males and 15 females), who underwent auditory assessment, central auditory processing assessment, and the Developmental Test of Visual Perception, were included. Correlations between auditory and visual skills in the general sample were analyzed using Pearson's correlation coefficient. The Mann-Whitney test was employed to compare visual composite scores and visual perception skills between groups with and without CAPD. The significance level for statistical tests was set at p<0.05. Results: visual skills were correlated with the auditory skills of temporal ordering, binaural integration, and auditory closure in the general study sample. Significant differences were found in the three visual composites evaluated between the groups with and without CAPD. Differences in figure-ground visual skills, visual closure, and form constancy were observed between the two groups. Conclusion: the students’ auditory skills were correlated, and CAPD impacted visual skill performance.
