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 .
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 ...
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 ...
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.
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 ...
For individuals between the ages of 4–5, the T.O.V.A test is 10.9 minutes long, while for older individuals the test lasts 21.6 minutes. The test may be presented as either a Visual or Auditory test, but both measure the same variables. During the first section of the test, the objective is to measure attention during a boring task.

The test comprises 8 subsets that represent everyday tasks and has three parallel forms. [1] It assess three aspects of attentional functioning: selective attention, sustained attention, and mental shifting. [2]
