What is it about?
This study examins the brain mechanisms related to young children's receptive familiarization with new words, and their relation to productive vocabulary size by recording ERP from 20-month-old children during a pseudoword repetition task.

Why is it important?
Children with large vocabularies recognized novel words after just three presentations, whereas those with low vocabularies needed five. This process was reflected in modulations of the N200–400 and a later fronto-central component.
Perspectives
These findings suggest a link between the onset of productive vocabulary growth and the rate of word familiarization. The vocabulary growth spurt in young children may be mediated by brain mechanisms related to fronto-central functioning.
