A general linear model using SPM’s canonical hemodynamic response function (HRF), modeled incentive anticipation, defined as the period between cue and target (Knutson et al., 2001) with regressors for each condition ($0.20 win, $5 win, $0.20 loss, $5 loss, $0) and six motion parameters. Contrasts for anticipation of reward ($0.2 and $5.0 combined) minus neutral and anticipation of loss (combined) minus neutral were calculated.
