Mixtures of strategies underlie rodent behavior during reversal learning
Fig 2
Non–uniform performance of mice in reversal learning.
(a) Example performance of a mouse (E54) in relation to its lapse rate in the last 5 days of training (days 26–30). Individual dots show the combinations of performance and lapse rates in single blocks. Lighter blue dots represent early blocks in the session while dark blue dots are late blocks. Red error bars represent the expected mean and standard deviation in performance and lapse rate assuming the mouse uses a single strategy. (b) Comparison of the observed standard deviation of block performances in the final five training sessions (black vertical lines) with the expected standard deviation in performance for an agent that uses a uniform strategy (box plots, n = 100 bootstrap runs). Each row represents one of 21 experimental mice (ID of animals shown on the y–axis). The average performance of each animal on the last 5 days of training, E, is shown on the right.
