  • Models predict choice of immediate option on each gain trial (in columns listed “Gain model”) or on each loss trial (in columns listed “Loss model”). In the left column, model predictors are listed below each model. Models listed “Between” contain data from subjects who received real rTMS and from subjects who received sham rTMS to region listed after word “Between.” OR, Odds ratio (eB). SE, SE of B. Intercept, Model Intercept. Imm. Rel. Value, Immediate Relative Value (percentage distance between the magnitude of the immediate option and the immediate equivalent of the delayed option). StimType, Stimulation Type (0, Sham rTMS; 1, Real rTMS). Session, Session Number (0, Session 2; 1, Session 3). X, Predictor is interaction of two terms. Models only contained interaction if significant at p < 0.05.
