The role of deployment of attention in the overlearning reversal effect (ORE) with aggressive and nonaggressive stimuli.

The study elucidated the role of deployment of attention in the appearance and magnitude of the overlearning reversal effect (ORE) with simultaneously occurring aggressive and neutral stimulus dimensions in a discrimination reversal-shift paradigm with 60 undergraduate college students. Confirming expectations, significantly larger overlearning reversal effect (ORE) was produced on the number of instrumental response errors and verbalized attentional errors with the less complex and less salient neutral, relevant-stimulus dimension. The findings that greater ORE, as reflected in attentional errors, was observed with the less salient but also less complex neutral stimulus dimension support the attentional explanations of the ORE phenomenon. These results contrast with those observed with traditional geometric stimulus material where greater complexity is associated with greater ORE.
