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 .
The term 2AFC is sometimes used to describe a task in which an observer is presented with a single stimulus and must choose between one of two alternatives. For example in a lexical decision task a participant observes a string of characters and must respond whether the string is a "word" or "non-word". Another example is the random dot ...
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 ...
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 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]
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.
