Very little experimental research has shown how the events from which verbs are learned affect children's representation of meaning. This study addressed these lacunae by systematically exploring how three different initial training contexts affect children's and adults' interpretation of novel action verbs. Brief, videotaped action events were used to teach children and adults novel verbs in 1 of 3 conditions. Subjects were asked whether these verbs generalized to other events differing only in outcome, manner, instrument, or agent. Initial representation of verb meaning was inferred from generalizations. Unlike 10-year-olds and adults, 3-year-olds' interpretations were (a) significantly context specific-preferring instrument and outcome elements of meaning in one context, but manner in another, and (b) consistently, though moderately biased to favor the manner of action. Results clearly demonstrate that both the young word learner and the context in which word learning occurs are equally important determinants of developing action verb concepts.
