Abstract
Abstract
Background: People with Down syndrome (DS) process the auditory information slower than people without intellectual disability. Some studies have reported a higher reaction time in the auditory tasks rather than the visual tasks, but the results are inconsistent.
Methodology: In this observational study, individuals with DS (14 girls, 10 boys) were selected availably and performed two auditory and visual tasks each with two stimuli separately, and the electroencephalography during performing the task (ERP) was recorded from three intermediate channels: Fz, Cz and Pz. data about the reaction time of the target stimulus, the number of the correct responses, the omission error of the target stimulus, the reaction time to the non-target stimulus, the commition error of the non-targeted stimulus, and the latency and the amplitude of the P300 component of ERP was investigated.
Results: The ANOVA results showed that there was not a difference between auditory and visual tasks in the reaction time to the target stimulus, the number of correct answers, the omission error, the reaction time to the non-target stimulus and the commition error. However, in the Pz channel, the latency of the P300 component in the auditory conditions is significantly higher than visual (F = 8.730, P
