Object-based attention and flexible adjustments of cognitive control based on contextual cues signaling the likelihood of distraction are well documented. However, no prior research has conclusively demonstrated that people flexibly adjust cognitive control to minimize distraction based on learned associations between task-irrelevant objects and distraction likelihood (i.e., object-based cognitive control). To fill this gap, we developed a novel paradigm during which participants responded to flanker stimuli appearing in one of multiple locations on two simultaneously presented objects. One object predicted a low likelihood of encountering an incongruent flanker stimulus and the other a high likelihood. After each response, the objects rotated clockwise such that all locations on average were 50% congruent, thereby eliminating confounds between location and likelihood of incongruence. Object-based cognitive control was evidenced by reduced flanker compatibility effects in the high compared to low conflict object. Across four experiments, we demonstrated that object-based cognitive control was dependent on a strong manipulation of the likelihood of conflict between objects and movement of the objects between trials. The novel evidence for object-based cognitive control is important in showing that people exploit not only location as a cue to guide control, but additionally objects, mirroring evidence on object and location-based attention.
