She has conducted experimental research in the malingering of head injury, placebo sleep, while in recent years focusing on sport-related topics such as sport superstition, sport concussion, stereotyping in athletes, and on how athletes may fake neuropsychological baseline tests to affect return-to-play decisions postconcussion.
