This study attempts to investigate whether the mutual exclusivity assumption is a lexical constraint or a learned strategy. The experiment uses the modified preferential looking paradigm. The infants were presented with two objects, one of which was familiar (eg. car) and the other was unfamiliar(eg. tool), while hearing either a known word or a nonsense word. Infants' looking time to each object was measured. The results indicate that both younger (11-17months: M=14months) and older infants(18-28months: M=24months) violate the mutual exclusivity in inferring the meaning of a novel word. The mapping of the known label to the familiar object increases in the older infant group. The results might be interpreted as an evidence against the mutual exclusivity as a lexical constraint, but still leave open to discuss as a learned strategy.
