Oct 1, 2016 · The topic was then primarily in psychology, but now equally often in neuroscience. This paper summarizes the background of the reaction time methods used in the original paper and findings that emerged later on the sensory consequences of orienting, mainly in the visual system.

Nov 3, 2020 · With tremendous nonchalance Michael Posner has traversed the borders of particular specializations, his mind occupied only by seeking an answer to the question of how our brain functions. And the pieces of that puzzle could not be found in one narrow subdiscipline.

Michael Posner has said that a better understanding of the human mind requires two things—the measurement of mental events and the mapping of those events to brain networks. During his career, Posner worked on both problems.
He started examining develop-mental and social issues and initiated a series of studies of temperament, testing the assumption that personality factors impact perceptual and cognitive processes. In particular, he investigated the development of executive attention during the early years of life.
In this chapter, we consider three major functions that have been prominent in cognitive accounts of attention (Kahneman 1973, Posner & Boies 1971): (a) orienting to sensory events; (b) detecting signals for focal (conscious) processing, and (c) maintaining a vigilant or alert state.

Michael I. Posner’s early work involved the measurement of mental operations by use of reaction time and other chronometric measures. In 1979 he began studies of patients to link mental operations to brain areas in the study of attention. To test hypotheses arising from this
