Mutual exclusivity in the psychology context refers to a cognitive principle, particularly observed in language acquisition, where children assume that each object has only one label or name. When learning new words, children often apply the mutual exclusivity principle by assuming that if an unfamiliar Word is presented alongside a known object, the word refers to something else. This principle helps them efficiently map new words to objects or concepts in their environment, facilitating vocabulary development.
Mutual exclusivity constraint refers to the notion that young children will assume that each object has but one label and that different words refer to separate and non-overlapping categories.
