a. fast-mapping.

Explanation:

Psychology explains rapid mapping as the human mind's ability to learn a new concept. Rapid mapping is of utmost importance in the linguistic development of a child, as it is through it that a child develops the ability to add new vocabulary words very quickly

The concept of rapid mapping was created through the study that sought to evaluate lexical acquisition of pre-school children and found that, at age three, they seemed to learn the meanings of new words by contrasting them with other words already known, even after a or very few exhibitions.  The result of the study proposed the existence of two phases of word learning, an initial rapid phase (rapid mapping) and a later slow phase (slow mapping), which would differ according to the quantity and quality of the representations associated with the new word .

Thus, the rapid mapping would be the partial knowledge, the initial link between the word and the referent, which occurs when the child notices a new lexical item and quickly apprehends some kind of information about it after few experiences. In turn, slow mapping, the most extensive phase of lexical acquisition, would be the gradual refinement of the initially mapped representation, with the addition of new information as the child has other experiences with the new word
