Isabel Gauthier is a cognitive neuroscientist currently holding the position of David K. Wilson Professor of Psychology and head of the Object Perception Lab[1] at Vanderbilt University’s Department of Psychology,[2] where she is also the co-director of the Cognition and Cognitive Neuroscience graduate program.[3]

She was born in Montreal, Québec, Canada, in 1971. She acquired her PhD at Yale University (1993-1998) under Michael Tarr. In 2000, with the support of the James S. McDonnell Foundation, she founded the Perceptual Expertise Network (PEN),[4] which now comprises over ten labs based across North America; in 2006 PEN became part of the NSF-funded Temporal Dynamics of Learning Center (TDLC).[5]

Awards and recognition[edit]

Gauthier has received the Young Investigator Award, Cognitive Neuroscience Society (2002),[6] the APA Distinguished Scientific Award for Early Career Contribution to Psychology in the area of Behavioral/Cognitive Neuroscience (2003)[7] and the Troland research award from the National Academy of Sciences “For seminal experiments on the role of visual expertise in the recognition of complex objects including faces and for exploration of brain areas activated by this recognition.” (2008).[8] She was elected Fellow of the Association for Psychological Science (2010).

Beginning in 2011, Gauthier serves as editor of the Journal of Experimental Psychology: General, where she introduced a brief report format and made report of effect sizes and consideration of power an editorial priority.

Research[edit]

Gauthier has researched many topics involved in perception, with a focus on the role of perceptual expertise in category-specific effects in domains such as faces, letters or musical notation. She incorporates different techniques to study these topics, including functional magnetic resonance imaging (fMRI), event-related potentials (ERP), and behavioral training studies using novel objects (e.g., Greebles, YUFOs, Ziggerins[9]).

One brain area frequently investigated by Gauthier and colleagues using fMRI is the fusiform face area (FFA). The FFA is believed to play an important role in face recognition, but Gauthier’s research has examined the role that FFA may play in the expert perception of non-face objects,[10] such as cars in car experts.
