Abstract

When two cues are presented together and reliably predict an outcome (AB-O1) an “overshadowing” effect is typically observed. That is, the relationship between these cues and the outcome is learned about less well than a cue presented on its own with an outcome (e.g., C – O1). The current study soug...
