The Posner cueing task, also known as the Posner paradigm, is a neuropsychological test often used to assess attention. Formulated by Michael Posner , [ 1 ] it assesses a person's ability to perform an attentional shift .
There are various manipulations in the design of the task, engineered to test specific behavioral dynamics of choice. In one well known experiment of attention that examines the attentional shift, the Posner Cueing Task uses a 2AFC design to present two stimuli representing two given locations. [2]
The Posner paradigm or Posner cueing task is similar to the dot-probe paradigm. [4] It is a sight test, which assesses the individual's ability to switch and focus on different stimuli presented. The subject focuses on a specific point, then attempts to react as quickly as possible to target stimuli presented to the sides of the specified point.
Posner studied the role of attention in high-level human tasks such as visual search, 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 ...
One form of cue that can be implemented in an inhibition of return task are exogenous cues. Exogenous cues are stimuli that are produced in the environment surrounding. Because one's attention is shifted to the stimulus without much thought or effort, these cues are seen as a form of reflex that the person has low control over.

A key property of visual attention is that attention can be selected based on spatial location and spatial cueing experiments have been used to assess this type of selection. In Posner's cueing paradigm, [4] the task was to detect a target that could be presented in one of two locations and respond as quickly as possible. At the start of each ...
