oa De productieve woordenschat van jonge Nederlandstalige kinderen

The productive vocabulary of young typically developing Dutch children aged 1;08 to 3;04 has been investigated. In the lexicon of the children nine categories of word types and tokens are examined. For types, a noun bias can be reported in children up to 2;01 years of age. About one third of the lexicon consists of nouns. The number of verbs and function words increases with age. The number of onomatopoeic words decreases. Personal-social words decrease only in types, not in tokens.
