Question

Quizplus · Accepted Answer

Overextension is when a child applies a word too broadly, such as calling all four-legged animals "doggie." Overregularization is when a child applies a grammar rule too broadly, such as saying "goed" instead of "went." Underextension is when a child applies a word too narrowly, such as only calling their family's pet cat "kitty" but not other cats. Fast mapping is when a child infers the meaning of a new word after only hearing it once or a few times.
