EARLY VOCAB
Children learn in semantic fields (same category of words)
(e.g: Child learns farm animals all around the same time)
But children often do not know the words meaning when they first know how to say it,
so they make errors at first.
Children quickly correct their errors using linguistic clues and past experiences (e.g by
asking questions, picking up on corrections)
However, parents can reinforce overextension by responding positively to child making
mistake or by labelling things using Child Directed Speech (e.g calling all dogs puppies)
TYPES OF ERRORS:
Overextension:
A word is used on objects that share a certain feature.
Types of overextension (coined by Rescoria 1980):
Categorical overinclusion- Word for one object extended to another in same semantic field (e.g
calling a cow a horse)
Analogical overextension- Word for another object extended to another not in the same semantic
field, but the objects are similar (e.g calling an orange a ball)
Predicate statements- An attempt to comment on where an object is you can’t see when viewing
an object you can see (e.g saying toy when looking at an empty toy box)
Underextension:
A word is used with a narrower meaning then it should be (e.g dog only used for family
dog and no other dogs)
Mismatch:
A word being used incorrectly with no reason why (e.g a telephone being called tractor)
