Dr. Peterson investigates how we perceive the world visually. She uses cognitive neuroscience techniques (e.g., ERPs, fMRI, and behavioral methods) to investigate:

  • the competitive processes producing object perception, and how they are affected by context;

  • the reciprocal relationship between perception and memory;

  • feedforward and feedback mechanisms in  perception;

  • how unconsciously activated knowledge affects attention and perception

  • how brain damage and aging affect the perception of, and memory for, objects


Her research is currently funded by the Office of Naval Research through a Multi-University Research Initiative. The National Science Foundation has been a major source of funding throughout her career.
