Figure 1.

(A) Illustration of reward, punishment and no-feedback scenarios of passive avoidance task (PAT). (B) Power-series regression curve of choice error probability computed across entire sample for operationalized early- and late-experience phases. Adjusted coefficient of determination (R_adj²) and decay coefficient (x^b) derived from power-series regression model. Brackets contain parametric, 95% confidence limits of x^b. Colour shading illustrates operationalization of early- and late-experience phases. (C) Linear regression curves for log choice error probabilities from early (blue) and late (grey) phase trials. R_adj² and regression slope estimates (β) derived from linear regressions fit to log trial by log choice error probability. Brackets contain parametric, 95% confidence limits of β. † denotes parametric, 95% confidence interval of x^b coefficient (B) or log–log regression β (C) did not contain 0.
