Research Interests: 
  • Investigating the basic mechanisms producing conscious object perception
  • Investigating how memory and attention affect object perception and detection
  • Investigating how visual perception develops and changes across the lifespan

My research investigates how we perceive the world visually, a topic about which much is known, but a great deal remains to be discovered. Specifically, my students and I use the new techniques of cognitive neuroscience (e.g., fMRI, ERPs, and behavioral methods) to investigate:

  • Inhibitory and facilitatory processes involved in assigning shape to certain portions of the visual field but not to others
  • The relationship between perception and memory
  • The processes used to learn new objects and to recognize familiar objects and how these change over the lifespan
  • How attention affects perception
  • How various parts of an object are bound together by the brain
  • How brain damage affects attention and object perception

We test college students, infants and older adults. We also test brain-damaged individuals and individuals with developmental disabilities.
