A schematic of the experimental trials seen by participants in Experiments 1 and 2. On their first exposure to each novel word, participants were asked to guess its correct referent. In Experiment 1, the second trial for each word was either a Same trial—the set of referents contained the participant’s previous hypothesis, or a Switch trial—the set of referents contained one the participant had previously not hypothesized. In Experiment 2, Switch trials were replaced with New Label trials that showed same set of referents but a played a novel word. The number of referents on the screen and the interval between successive exposures to the same word varied across conditions.
