Janet (Jan) K. Andrews was a founding member of Vassar’s Cognitive Science Program (now Department.) Her research interests concern the relationships between perception, language, and cognition. A long-term interest is in the structure and formation of category concepts and in the relationship between perceptual processes and abstract knowledge. Her research investigates these issues primarily by examining the category learning behavior and perceptual judgments of adults and testing effects known as learned categorical perception (CP) to determine their nature and robustness.  Another strong interest is in promoting transparency and replicability in cognitive science research.
