CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Underextension occurs when a categorical term (a word used to describe a group of things) is used in language improperly by only using it for one object instead of all objects that belong in that category.

Detailed explanation-2: -It’s the opposite of overextension where a child uses a word for too many different cases. Example of underextension: Kitty might mean the family cat, but not other cats. Underextensions may occur because a general word (like kitty) is almost taken as a name, not as a word.

Detailed explanation-3: -(linguistics) Application of a term to too few referents, as for example when a child uses cat to refer only to the family pet.

Detailed explanation-4: -n. the incorrect restriction of the use of a word, which is a mistake commonly made by young children acquiring language. For example, a child may believe that the label dog applies only to Fido, the family pet.

Detailed explanation-5: -Underextension: This is a common semantic error made by children. It occurs when a word is given a narrower meaning that it has in adult language. E.g. Only use the word ‘dog’ for the family dog, not any other dogs. Overextension: This is the opposite of underextension and is also a feature of child’s early language.
