A test of the 'specificity hypothesis' in children with Down's syndrome

find out whether that word was understood in a contextuallyflexible or context-bound way. A detailed record was also kept of developing production.

The first concerns the number of words that a child understands when production first begins; the second concerns what a child understands about a particular word at the point when it is first produced. The results show considerable variation in the lag between comprehension and production, but they also highlight the very extensive lexical knowledge that a child typically has about a word before it
