Lexical And Semantic Development Flashcards
When do children usually use their first words?
At around 18 months
How many words should children know by 18 months?
What about 24 months?
At 18 months, a vocabulary of around 50 words, though it has been suggested that they KNOW around 250, just don’t use them.
At 24 months 200 words are actively used
What is underextension?
Semantic error where children use a narrower meaning for a word than in adult language. For example using the word ‘cat’ for the family cat and no other cats
What is overextension?
When a child gives a word a broader meaning that intended, for example using the word daddy for all men. When children have limited vocabulary, this happens frequently- and decreases as they learn more words to fill the gaps
Who developed the three stages of semantic development?
Aitchinson (see stages in language development pack)
