Question

Quizplus · Accepted Answer

The Answer is Both fast-mapping and logical extension refer to a child's terrific surge of perceptual interrelationships among words. Fast-mapping refers to the phenomenon by which young children develop an interconnected set of categories for words, a kind of mental map, which makes speedy vocabulary acquisition possible. Fast-mapping speeds the development of learning new words because children immediately assign a new word to one of the categories in their mental language grid. Thus, the first time a child sees a pet ferret, he may assign it the status of a type of dog or a kind of cat, since he does not have a weasel concept. The child's understanding of the new word is not always precise. Children refine their understanding through use and experience.
Logical extension refers to a child applying a newly learned word to another related object. A young girl who was just read a story about a Dalmatian dog may then refer to a black-and-white cow as a Dalmatian cow.
