Research Interests:

  • Visual cognition and spatial-working memory
  • Interaction between linguistic and perceptual representations of perceptual attributes

My primary line of research seeks to understand how people process spatial information. I feel that understanding how people encode, store and operate on spatial information is fundamental to understanding shape and object perception, mental imagery, and cognitive maps. Ongoing projects include studying spatial working memory and investigating how categorical spatial relations are integrated across objects. I am also interested in the relationship between representations of colors and color words, as embodied in performance on the Stroop task, and the role of cognition in perception.
