Action is informed by memory, and so it is often critical to get the details of a memory right. Nevertheless, people often get them wrong, and in predictable ways. My primary areas of research concern memory decisions, memory errors, and the influence of emotions like anger, suspense, and threat on cognitive functioning. My graduate students and I have begun to pursue some of these topics in the context of eyewitness memory and identification.
