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. It has been used and modified to assess disorders, focal brain injury, and the effects of both on spatial attention.
Using Posner's Spatial Cueing Task, Alivesatos and Milner (1989; see [10]) found that participants with frontal lobe damage demonstrated a comparably smaller attentional benefit from the valid cues than control participants or participants with temporal lobe damage. Voluntary orienting of frontal lobe patients appear to be impaired.
IOR was first described in depth by Michael Posner and Yoav Cohen, [1] who discovered that, contrary to their expectations, reaction times (RT) to detect objects appearing in previously cued locations were initially faster to validly cued location (known as the validity effect), but then after a period of around 300 ms, response times to a previously cued location were longer than to uncued ...
Posner and Cohen unexpectedly found that visual search reaction times to detect objects appearing in a previously cued location took longer than when they appeared in a non-cued location, provided the time in waiting for the target (object) to appear was longer than 300 ms after the initial cueing.

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 ...
The Posner Center of Justice for Pro Se’s has a bold vision: to provide pro bono representation, but also to focus on assisting pro se litigants behind the scenes to help them to successfully ...
The standard contextual-cueing task first developed by Chun and Jiang in 1998 pioneered research in the development of this area of study. The results showed how, in global contexts, implicit learning and memory of visual context can navigate spatial attention towards task-relevant aspects of a scene.
