Portland News Station Highlights Psychology Professor’s Synesthesia Research

A recent story on Portland's KATU News about an unusual sensory phenomenon called synesthesia featured the expertise of Mark Stewart, Willamette psychology professor and department chair.

Synesthesia is a neurological condition where people involuntarily join the information from one sense with a perception in another sense. For example, they might associate a taste with a certain sound, or see a color whenever they view a particular letter of the alphabet.

Stewart has spent much of his time at Willamette researching this condition. "Synesthesia has been described as a very small peep hole into understanding human consciousness," he said in the story. "What interests us is understanding more about how the brain organizes information."

Stewart teaches courses on sensation and perception, research methods, neuroscience and human experimental psychology. His recent work on time-space synesthesia will appear in a forthcoming issue of the journal Cortex. Learn more about him here.
