We investigated preschoolers' selective learning from models that had previously appeared to be reliable or unreliable. Replicating previous research, children from 4 years selectively learned novel words from reliable over unreliable speakers. Extending previous research, children also selectively learned other kinds of acts--novel games--from…

Repetition priming refers to the facilitation of stimulus processing due to prior processing of the same or similar stimulus, and is one of the most primitive ways in which experience and practice can affect performance. Previous studies have produced contradictory results regarding the stability of repetition priming across development. Drawing…

Two alternative hypotheses can be used to explain how young children acquire the cardinal meaning of small-number words. The first stresses the role of counting and predicts better performance when the items are presented in succession. The second considers the role of subitizing and predicts better performance when the items are presented…

Attempts to determine whether children can use social-pragmatic cues to determine "what kind" of referent, object, or action an adult intends to indicate with a novel word. Doubts that children assume that a novel word refers to whatever nameless object is present. Suggests that lexical acquisition rests fundamentally on children's…

Examines whether knowledge of functional properties of a referent for a new name influences children's first guesses about whether that name refers to an object or a substance. Suggests that children do not rely on a single source of information, but rather draw on various kind of information, including perceptual characteristics of the entities…
