Design of Experiment 3

Group Phase 1, 3 Days Phase 2, 3 Days Phase 3, extinction Test
Same–Ext A (12A+/3AX+ )1 (12B+/3BX+ )1 (400 A− )1 X1
Same–Ext B (12A+/3AX+ )1 (12B+/3BX+ )1 (400 B− )1 X1
Same–No Ext (12A+/3AX+ )1 (12B+/3BX+ )1 (Context)1 X1
Different–Ext A (12A+/3AX+ )1 (12B+/3BX+ )1 (400 A− )2 X2
Different–Ext B (12A+/3AX+ )1 (12B+/3BX+ )1 (400 B− )2 X2
Different–No Ext (12A+/3AX+ )1 (12B+/3BX+ )1 (Context)2 X2

Note. A and B = competing stimuli; X = target cue; + = footshock; Same = trained and tested in the same context; Different = trained in Context 1 and tested in Context 2; Ext = extinction. Numbers next to the stimuli indicate the total number of trials in that phase. Subscripts indicate different contexts. Slashes indicate interspersed trials.
