Exploring Pitch and Length Perception: An EEG Study on Quantity Discrimination in preschoolers with Developmental Language Disorder

Abstract

Here, we present the raw EEG data from our investigation into the neurophysiological differences in language processing between children with developmental language disorder (DLD) and their typically developing peers. Building on previous findings of prosody perception difficulties and their impact on language development, we aim to describe the Mismatch Responses (MMR) of both groups when perceiving the unique three-way quantity distinction of Estonian prosody. Our methodology involves comprehensive psychometric testing and complete EEG examinations for the DLD group, alongside a passive oddball paradigm with various stimuli. We also explore potential correlations between neurophysiological and behavioral results and investigate the influence of environmental factors.
