Results of Experiment 1C shown as novelty exploration ratios by age group. The PD17 group is the same as that reported from Exp. 1A. The PD21 and PD26 groups shown are only from the Restricted group in Exp. 1C. Exploration ratios were calculated as (time exploring novel)/(total exploration time of both objects). Rats exhibited significant preference for the displaced object only at PD21 and 26 ages. (#p <.05).
