Education
Posner studied the role of attention in high-level human tasks such as visual search, reading, and number processing.
Posner studied the role of attention in high-level human tasks such as visual search, reading, and number processing.
He is currently an emeritus professor of psychology at the University of Oregon (Department of Psychology, Institute of Cognitive and Decision Sciences), and an adjunct professor at the Weill Medical College in New York (Sackler Institute). A Review of General Psychology survey, published in 2002, ranked Posner as the 56th most cited psychologist of the 20th century. A test of an individual"s capability to perform attentional shift was formulated by him and bears his name - the Posner cueing task.
In Chronometric Explorations of Mind, published in 1976, Posner applied the subtractive method proposed 110 years earlier by Franciscus Donders to the study of several cognitive functions such as attention and memory.
The subtractive method is based on the assumption that mental operations can be measured by decomposing complex cognitive tasks in sequences of simpler tasks. The method assumes that the effect of each mental operation is additive and that it is possible to isolate the effect of a single mental operation by comparing two tasks that differ only by the presence or absence of that mental operation.
(See Mental chronometry for additional information on Donders" experiment)
Posner applied the same subtractive principle to the study of attentional networks using Positron Emission Tomography (Positron Emission Tomography), a neuroimaging technique that produces three-dimensional functional maps of the brain. In May 2003, 10 speakers and a large audience gathered at the University of Oregon in Eugene to pay tribute to the enormously influential contributions Michael Posner has made to the disciplines of psychology and cognitive neuroscience.
The impact of Posner"s theoretical and empirical contributions has been recognized through fellowship in the American Psychological Association, the Association for Psychological Science, the Society of Experimental Psychologists, the American Academy of Arts and Sciences, the American Association for the Advancement of Science, and the National Academy of Sciences. In 2009 Posner, a graduate of the University of Michigan, was awarded the National Medal of Science. In 2014 he was elected a Corresponding Fellow of the British Academy. His students include Stanislas Dehaene, Jon Driver, John Duncan, Vicki Hanson, Steven Keele, Daniel Levitin, Bruce McCandless, and Elise Temple.
