Question

Quizplus · Accepted Answer

Underextension refers to a child's limited use of a word to a specific object only, in this case, Gina's use of the word "Dolly" only for one specific doll. The other options do not accurately describe Gina's situation. Overextension would be if Gina used the word "Dolly" to refer to all dolls or even other objects unrelated to dolls. Overgeneralization is when a child applies a word too broadly, such as using the word "dog" to describe all four-legged animals. Undergeneralization, on the other hand, is when a child uses a general word for a specific object only, such as using the word "animal" only for dogs and cats.
