Proposes that young children employ two ordered, nonverbal classification strategies to interpret vague referential instructions: first, they rely on context; then, if the first strategy fails, they guess.

Describes the interactions of 1five mothers inexperienced with deaf people and a deaf five-year-old, a hearing two-year-old and a hearing four and one-half-year-old.

Compared comprehension of novel communicative signs to assist 2.5- and 3-year-old humans, chimpanzees, and orangutans find hidden objects during a hiding-finding game. Found that children at both ages performed above chance with all signs. No ape performed above chance for any signs not known before the experiment despite three times as many…

Addressing methodological limitations, Study One compared parent-child interactions of normal and language-delayed children; Study Two investigated whether mothers adjust the length of their utterances to the child's ability to comprehend or to produce language; Study Three probed interactional variables associated with variations in the…
