Fig. 2.

Infants’ novelty preferences during the test phases of Experiments 1, 2, and 4. The y-axis shows infants’ novelty preference in each experiment, calculated by subtracting looking times on familiar trials from looking times on novel trials. Positive values correspond to a novelty preference. In Experiment 1, infants who were familiarized to the ABA pattern in the Informative condition showed a preference for novel tone patterns over familiar tone patterns (also see Supplementary material). Infants did not show a novelty or familiarity preference in any other conditions or experiments. Error bars represent +/− 1 SEM (between subjects).
