The effect of phonological neighbourhood density on word production in children: An ERP study

Phonological neighbourhood density (PND) refers to the number of words that are phonologically similar to a target word (e.g., cat – hat, cut, cap etc.) and has been identified to affect vocabulary development in young children. Previous research shows that toddlers who struggle to talk mainly produce words that have many phonological neighbours while their typically developing peers use words that have either many or few phonological neighbours. These findings indicate a differential processing demand depending on a word´s PND. I will present neurophysiological data that support the idea that PND affects underlying processes involved in speech production in young children. It is hoped that these results will contribute to a better understanding of how word-inherent properties can influence language production and will lead to a better understanding of atypical language processing, to ensure that early language intervention is most effectively targeted in children who struggle to talk.
