Three Stages of Attention Orienting
Another influential idea came from Posner and Petersen in 1990, who theorized that the orienting of attention could be organized into three distinct stages. They argue that in order for a person to orient to a new location, they first have to disengage, or take attention away from where it is currently focusing. Next, the shifting of one’s attention would occur from one stimuli to another. Finally, attention would be engaged, or focused onto the new target. This review attempts to look at the research regarding neural correlates of these physical shifts of attention, specifically focusing on the areas of covert and overt attention, as well as, voluntary and automatic attention shifts. Research often disagrees about the amount of overlap in the neural systems for these different types of attention, and therefore research supporting both views is discussed below.

Famous quotes containing the words stages and/or attention:
“The four stages of man are infancy, childhood, adolescence and obsolescence.”
—Art Linkletter (20th century)
“It has lately been drawn to your correspondent’s attention that, at social gatherings, she is not the human magnet she would be. Indeed, it turns out that as a source of entertainment, conviviality, and good fun, she ranks somewhere between a sprig of parsley and a single ice- skate. It would appear, from the actions of the assembled guests, that she is about as hot company as a night nurse.”
—Dorothy Parker (1893–1967)
