Bayes factor values

Factor Tested	DT	%Correct	%TO	SumLogLR	Urgency Intercept	Urgency Slope
SESSION	3.87	3.77	3.91	5.23	3.46	3.48
SESSION × TRIAL	3.91	3.77	3.91
SESSION × TIME				21.28

First column specifies the factors tested for which a Bayes factor (BF) value was computed. Other columns represent the BF values obtained for each behavioral measure in the tokens task. Overall, BF values ranged between 3.46 and 21.28, indicating substantial to strong evidence for a lack of effect of the SESSION on subjects’ behavior. %Correct, percentage of correct choices; %TO, percentage of time out trials; DT, decision time; SumLogLR, sum of log-likelihood ratios.
