 Reyna's research program adopts a cognitive neuroscience perspective on topics pertaining to judgement, decision making, and memory over the life span.In collaborative work with Brainerd, Reyna focused on how emotions can distort memories, especially for events that have negative emotions associated with them.To account for why people often remember things that never happened (i.e., experience false memory or memory illusions), fuzzy-trace theory proposes that verbatim and gist memories are stored separately and activated in parallel.
