Michael I. Posner (; born September 12, 1936) is an American psychologist who is a researcher in the field of
attention
Attention or focus, is the concentration of awareness on some phenomenon to the exclusion of other stimuli. It is the selective concentration on discrete information, either subjectively or objectively. William James (1890) wrote that "Atte ...

Posner studied the role of attention in high-level human tasks such as
visual search
Visual search is a type of perception, perceptual task requiring attention that typically involves an active scan of the visual environment for a particular object or feature (the target) among other objects or features (the distractors). Visual s ...
, reading, and
number processing. More recently he investigated the development of attentional networks in infants and young children. 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 PET (
Positron Emission Tomography), a neuroimaging technique that produces three-dimensional functional maps of the brain. In ''Images of Mind'', published with
Marcus Raichle in 1994, Posner investigated brain localization of cognitive functions by looking at the patterns of brain activation in progressively more complex cognitive tasks.
Posner won the 2001 University of Louisville Grawemeyer Award for Psychology, along with Marcus Raichle and
Steven Petersen.

published an edited volume in tribute to Posner's work. As reported by Steven W. Keele and Ulrich Mayr in that volume, "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 citation read "For his innovative application of technology to the understanding of brain function, his incisive and accurate modeling of functional tasks, and his development of methodological and conceptual tools to help understand the mind and the development of brain networks of attention".
In 2012, the National Academy of Sciences honored Posner with the John J. Carty Award for the Advancement of Science "For outstanding contributions to the understanding of spatial attention and for pioneering investigations of the neural basis of cognition using non-invasive functional brain imaging methods".
In 2014, he was elected a
Corresponding Fellow of the British Academy.
