    "abstract": "How do learners gather new information during wordlearning? We present evidence that adult learners will chooseto receive additional training on object-label associations thatreduce ambiguity about reference during cross-situationalword learning. This ambiguity-reduction strategy is related toimproved test performance. We find mixed evidence thatchildren (4-8 years of age) show a similar preference to seekinformation about words experienced in ambiguous wordlearning situations. In an initial experiment, children did notpreferentially select object-label associations that remainedambiguous during cross-situational word learning. However,this may be explained by some children having relatively highcertainty about object-label associations for which they didnot see evidence disconfirming their initial hypothesis. In asecond experiment that increased the relative ambiguity oftwo sets of novel object-label associations, we found evidencethat children preferentially make selections that reduceambiguity about novel word meanings.",
