Anne Marie Treisman (née Taylor; 27 February 1935 – 9 February 2018) was an English psychologist who specialised in cognitive psychology. She researched visual attention, object perception, and memory. One of her most influential ideas is the feature integration theory of attention, first published with G. Gelade in 1980. Treisman taught at the University of Oxford, University of British Columbia, University of California, Berkeley and Princeton University. In 2013, Treisman received the National Medal of Science from President Barack Obama for her pioneering work in the study of attention. During her long career, Treisman experimentally and theoretically defined the issue of how information is selected and integrated to form meaningful objects that guide human thought and action.
