Anne Marie Treisman. 27 February 1935—9 February 2018

The psychologist Anne Treisman dedicated her career to the study of attention and perception, a central concern of cognitive science. While still a graduate student, she modified and reformulated the leading theory of auditory attention. Her discoveries and insights into the role of visual attention in the perception of objects, to which she devoted her subsequent decades of research, have had a lasting influence, not only in experimental psychology but also in vision research, neuroscience and artificial intelligence. In a period of rising interest in the brain, her foundational theories inspired thousands of experiments in her own field and others, and the originality and precision of her experimental design confirmed the continued relevance of behavioural research to the scientific enterprise. Treisman's accomplishments were recognized by the National Academy of Sciences in the USA in 1994 and by the American Academy of Arts and Sciences in 1995. In 1996, she became the first psychologist to win the Golden Brain Award. She received the University of Louisville Grawemeyer Award in Psychology in 2009, and was awarded the National Medal of Science by President Barack Obama at a White House ceremony in 2013.
