Research Interests

Dr. Papesh’s lab investigates human attention, perception, and memory, using converging techniques to study multiple, interrelated phenomena. Across studies, they collect data at multiple levels of analysis, emphasizing classic techniques, while also incorporating newer dynamic measures, including mouse-tracking, oculomotor and psychophysiological measures, and direct neural recordings. 

Some of the research currently going on in the lab includes: 

  • How do top-down processes (e.g., expectations) and bottom-up factors (e.g., salience) influence the size of the attentional window?
  • What are the costs and benefits of attentional engagement?
  • How do individuals match faces to photograph IDs, and what, if anything, do they remember about the faces? 
  • What can we learn about memory (and forgetting) from monitoring eye movements?
  • Why does incidental memory improve when tasks become more challenging?
  • What are the retrieval dynamics of recognizing familiar words, faces, and sentences?
  • How do people search for multiple objects simultaneously?
  • Any students interested in working in the lab should contact Dr. Papesh via email, at She will be accepting applications for new graduate students for Fall 2020 entry.
