Abstract: In this study, we analyse the statistical significance of the dichotic listening test results using two methods. The first method is based on the Agresti-Coull interval, and the other one is based on the sequential Wald analysis. We also propose a way to estimate the guaranteed boundaries for the eventual laterality index at every step of the dichotic listening test using the random walk method. This work is based on the analysis of 87 dichotic listening protocols of 59 children and adolescents of 4-16 years of age (patients of children's psychoneurological clinic) and three healthy adult volunteers. The dichotic listening was carried out in the clinical and laboratory conditions.
