Hot off the press effects of long term memory on visual search boost by reward associations

Zita Patai and Sonia Doallo lead pair of studies showing facilitation of perceptual discrimination by long-term spatial contextual memory for targets embedded in complex scenes, and the boosting of these effects by positive reward associations. Both papers are published in the Journal of Cognitive Neuroscience. They contain some interesting twists about the mechanisms by which memory can guide perception and help advance our understanding of the interactions among reward, memory, and perceptual systems in the human brain.
