Research on memory and stress published
Research on memory and stress, conducted by Phillip Zoladz, assistant professor of psychology, and his team, is the basis of two recently published articles.
The first describes a study in which participants were stressed immediately before memory testing, then tested 24 hours following learning. Results showed that stress differentially influenced participants' memory, depending on their corticosteroid response to the stressor.

The second article describes a study in which participants were stressed immediately before learning several lists of words, designed to enable investigators to examine false memory production. The study showed that stress reduced participants' false memories of what they had learned and actually enhanced true memory selectively in females. These findings have implications for how stress affects eyewitness accounts of a stress-inducing event, such as a crime.
