A. Cumulative trials required to attain each stage of discrimination and reversal learning. B. Total error trials significantly increased during the first session of reversal and subsequently decreased significantly across each subsequent stage of reversal. C.
Win-stay closely reflected total percent correct, significantly decreasing during early reversal and significantly increasing across reversal sessions. D. Cumulative total errors to attain each stage of discrimination and reversal learning. E.
lose-shift trials did not significantly increase until chance reversal, before significantly decreasing again at criterion. F.
Regressive error trials, another switch trial type, closely mirrored lose-shift, increasing at chance before decreasing again at criterion. Data are means ±SEM. N=12 mice per recording session. * = P<.05, compared to Discrimination criterion; #= P<.05, compared to early reversal; and †=P<.05, compared to chance reversal.
