The differential outcomes procedure (DOP) refers to the increase in performance and terminal accuracy observed in conditional discrimination tasks when each of the stimuli-response associations to be learned is followed by a unique outcome. In addition to the benefits of the DOP found with conditional discrimination learning, there is an increasing amount of evidence suggesting positive effects with memory tasks as well (see López-Crespo & Estévez, 2013, for a review). The aim of the present study was to investigate whether this procedure would also be effective in improving visual recognition memory in healthy elders and patients with Alzheimer’s disease. Results showed that participants in both groups had a statistically significant better accuracy when a specific outcome was paired with the to-be-remembered stimulus as compared to a non-differential outcomes condition. This finding, along with those from previous studies, suggests that the DOP can be an effective technique to facilitate working memory-based performance in both normal and pathological aging.
