Anne Treisman, a visionary psychologist at Princeton, died Friday, Feb. 9, at age 82.

Treisman made major contributions to the understanding of attention and perception by exploring the mechanisms of attention, first in selective listening, and then in visual perception. Her work helped explain how we focus on relevant auditory information in noisy environments and how we extract meaning from complex visual scenes. The concepts she proposed have influenced generations of scientists in cognitive psychology.

Treisman’s work has appeared in numerous book chapters and more than 80 journal articles. Over the decades, her research has helped illuminate new areas of study in cognitive science.

She was the James S. McDonnell Distinguished University Professor of Psychology, Emeritus, who joined the faculty in 1993 and transferred to emeritus status in 2010. In 2015, a gift to Princeton established the Daniel Kahneman and Anne Treisman Center for Behavioral Science and Public Policy.

The University flag over East Pyne will fly at half-mast in her memory February 13-15, 2018.
