We can more precisely tune attention to highly rewarding objects than other objects in our environment, but how our brains do this is unknown. After a few trials of searching for the same object, subjects' electrical brain activity indicated that they handed off the memory representations used to control attention from working memory to long-term memory. However, when a large reward was possible, the neural signature of working memory returned as subjects recruited working memory to supplement the cognitive control afforded by the representations accumulated in long-term memory. The amplitude of this neural signature of working memory predicted the magnitude of the subsequent behavioral rewardbased attention effects across tasks and individuals, showing the ubiquity of this cognitive reaction to high-stakes situations. © The Author 2013.
