Protect Ctrl | X- | 198 D- | 1.62 | 1.34 | 1.67 | 1.70 |
Note: Ctrl = control; Ext = extinction. A-D and X were cues in a Pavlovian lick suppression procedure. A was counterbalanced with D, and B was counterbalanced with C. + represents the occurrence of a surrogate outcome that was paired with a footshock US in a session before testing. Thus, experimental manipulations were embedded in a sensory preconditioning procedure (see text for details). Obs = observed suppression (log s) to X at test. RWM = predictions by the Rescorla Wagner model, WCM = predictions by the Within-Compound model, and CEM = predictions by the Conjoint Error model.
