Experiment 1: CS A means are ANCOVA adjusted with pre-CS as the covariant. Groups Blk-DiffA2, Blk-Same, and Acq-Con were those in which strong responding to cue A was expected due to prior training of the competing cue in Phase 1 (Groups Blk-DiffA2 and Blk-Same) or Phase 2 (Group Acq-Con). Higher bars indicate stronger suppression and lower bars indicate weaker suppression. Weaker responding to cue A was expected in Group Blk-DiffA1 because at test cue A emanated from a location different from that when it had been reinforced. Discrimination of the reinforced and nonreinforced locations is (nonsignificantly) suggested in the lower responding to cue A in Group Blk-DiffA1 than in Group Blk-DiffA2.
