  1. Output from frequentist and Bayesian paired t-tests on the Q-learning model’s parameters for day 1 and day 2 data. No significant differences were found. BF01 > 3 reflects moderate evidence in favour of the null hypothesis. Cohen’s d and 95% confidence intervals are presented for frequentist t-tests, and the posterior median and 95% credible intervals for the Bayesian t-tests.
