The National Science Foundation has officially awarded our lab a new grant entitled “Perceptual Categorization in Real-World Expertise”. Now the work begins.Read More
Category Laboratory at Vanderbilt
supported by NSF, NEI, and Vanderbilt UniversityIn the CatLab, we study visual cognition, including visual categorization, visual memory, and visual decision making. We study how objects are perceived and represented by the visual system, how visual knowledge is represented and learned, and how visual decisions are made. We approach these questions using a combination of behavioral experiments, cognitive neuroscience techniques, and computational and neural modeling. One line of work, funded by the National Science Foundation, investigates the temporal dynamics of visual object categorization and perceptual expertise for objects and faces. Another line of work, funded by the National Eye Institute, uses computational modeling of visual decision making to predict behavioral dynamics and neural dynamics.
Congrats to former CatLab graduate student Alan Wong,
who just earned tenure at the Chinese University of Hong Kong. Well deserved!Read More
Congratulations to Braden Purcell for winning the The Pat Burns Memorial Graduate Student Research Award.
Pat Burns touched generations of doctoral students during her nearly four decades of service to Vanderbilt University. In memory of her tireless efforts to help guide our students through all phases of their graduate education, the Department of Psychology establishes a Graduate Student Research Award to recognize outstanding achievement in research by our most outstanding graduate students. The recipient receives a plaque and a $500 award.
Along with Michael Mack and Jennifer Richler, this makes the third CatLab member to win this prestigious award.Read More
Jonathan Folstein, a recent postdoctoral fellow in the
CatLab and OPL, has accepted a faculty position in psychology at Florida State University. Congratulations Dr. Folstein!Read More
Congratulations to Akash Umakantha for his acceptance into the Cold Spring Harbor Undergraduate Research Program. Akash is an undergraduate in biomedical engineering and neuroscience who is working on a research project with Braden Purcell and Thomas Palmeri.Read More

Jianhong Chen is joining the lab this fall as a new graduate student in Psychological Sciences. Jianhong is getting her undergraduate degree from Peking University, one of the top three universities in China, where she worked with professor Fang Fang. Her research at PKU focused on adaptation, perceptual learning and EEG. For her graduate study, she is interested in perceptual expertise.
We also have two undergraduates working in the laboratory this summer on research fellowships. Billy Bunce will work with Jenn Richler and Mike Mack on a project modeling perceptual expertise. Akash Umakantha will work with Braden Purcell on neural models of perceptual decision making.Read More
Congratulations to David Ross for successfully passing the oral defense of his PhD thesis
from Cardiff University. Well done Dr. Ross!Read More
Tim Vickery worked in the lab as an undergraduate and as a research assistant before going on to earn his PhD
in psychology at Harvard with Yuhong Jiang. Tim is currently a postdoctoral fellow at Yale University with Marvin Chun. Tim just accepted a faculty position at the University of Delaware. Congratulations Tim!Read More

The Temporal Dynamics of Learning Center (TDLC) recently received renewal of funding from the National Science Foundation with a five year $18 million grant. The TDLC, one of six Science of Learning Centers funded by NSF, provides core support for the Perceptual Expertise Network (PEN). PEN is co-directed by Palmeri and Gauthier, who also sit on the Executive Committee for the TDLC.
A story on the funding renewal appears here: http://news.vanderbilt.edu/2011/11/pen-grant-renewal/Read More
