When learning a new word, children apply it to other objects in the same category, a strategy known as ______.

A) logical extension
B) fast mapping
C) mutual exclusivity
D) telegraphic speech

Logical extension involves using a newly learned word to describe other objects within the same category, showing an understanding of the word's meaning beyond just the specific object it was initially learned for. Fast mapping refers to the ability to quickly learn a new word after just one exposure, but it doesn't necessarily involve applying the word to other objects in the same category. Mutual exclusivity is a bias towards assuming that objects only have one name or label, which can actually inhibit the application of a new word to other objects. Telegraphic speech is a stage of language development in which children use short, simplified phrases without function words.
