Behavioral performance. A, Performance during standard (STD) and ambiguity (AMB) sessions. The performance decreased by ∼10% in the AMB sessions compared with the STD sessions. Dotted line indicates presurgical performance criterion for surgery (70%). B, Performance as a function of ambiguity level (0 lowest, 4 highest). The behavioral performance decreased as the ambiguity level increased. The performance significantly decreased in the high ambiguity conditions (level 3–4) compared with the STD session (dotted line). ***p < 0.0001. C, The object-categorical bias indices were averaged across animals and plotted as a function of sessions. Overall, no significant bias was found toward a particular object category in any of the sessions. D, There was no significant effect of learning across sessions in the AMB sessions. Because only one rat performed on day 5, the analysis was conducted on data obtained from days 1–4 only. Data are mean ± SEM.
