Michael I. Posner is a pioneer in the field of cognitive neuroscience, and was one of the first researchers to use then-emerging brain-imaging techniques to understand the brain processes underlying complex tasks. Posner studied the role of attention in tasks such as reading and number processing, and the development of attentional networks in infants and young children. He devised the Posner Cueing Task, which measures an individual’s ability to shift attention. He received the highest scientific honor in the United States in 2009 when he was awarded the National Medal of Science.
In this interview with APS Past President Nancy Eisenberg, recorded before a live audience at the 2015 APS Annual Convention in New York City, Posner reflects on a trailblazing career that spans more than 50 years.
