- The development of meaning: Lexis and Semantics
- Meaning (Aitchison 1987)
- Labelling: the process of attaching words to objects; as the child learns more about world their capacity to connect words with increasing range of objects grows
- Packaging: by trying to ascertain boundaries of a label, child sometimes confuses hypernyms and hyponyms (see overextension)
- Network Building: having labelled objects children start to identify connections between them, similarities and differences for instance.
- Vocabulary
- Productive vocabulary: by 18 months, child has PV of 50 words, the words that their muscular and motor development enables them to pronounce correctly
- Receptive vocabulary: relates to the words a child recognises/understands but cannot verbally produce
- Extension
- Underextension is when ascribed meaning is narrower than meaning in adult language: for instance, 'apple' for 'fruit'. Hyponym for a hypernym.
- Overextension is the widening of a word so that it applies not just to actual object but also to others with similar properties or functions, Leslie Rescorla (1980) defined these to three categories
- Categorical overextension: confusing a hypernym (broad category) with a hyponym (specific example within that category), eg. 'fruit' for 'apple'
- Analogical overextension: associating unrelated objects with one or more common. features, eg. seeing a red ball and then calling a red cushion a 'ball
- Predicate overextension: conveying meaning relating to absence (eg. making utterance 'dog' when looking at a dog kennel)
- Meaning (Aitchison 1987)
