My graduate students and I conduct experimental and theoretical research
on visual cognition. We are concerned with how humans obtain meaning from
visual stimuli such as pictures and words. I am interested in mathematical
and computer models of perception, reading, picture processing, memory,
cognition, decision making, and response selection. We are currently investigating
the structure of lexical, pictorial, and semantic memory in visual recognition.
We are also investigating whether truly biolingual individuals have a separate
semantic memory for each language or a single unitary abstract, conceptual
memory which serves both languages.
