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 task set is defined as an effective intention to perform a task, accomplished by configuring one's mental state (e.g. attention) to be in accordance with the specific operations demanded by the task. Tasks that have been used to define these task sets include: categorization of numbers, letters, or symbols; identification of colors or words ...
Memory is a very broad function which includes several distinct abilities, all of which can be selectively impaired and require individual testing. There is disagreement as to the number of memory systems, depending on the psychological perspective taken.
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.
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 consists of two boards with pegs and several beads with different colors. The examiner (usually a clinical psychologist or a neuropsychologist) presents the examinee with problem-solving tasks: one board shows the goal arrangement of beads, and the other board is given to the examinee with the beads in a different configuration.
His Go/no-go task, which was one of the tasks screening for the frontal lobe damage, "count by 7", hands-clutching, clock-drawing task, drawing of repeatitive patterns, word associations and categories recall and others became standard components of neuropsychological assessment and mental status screening.
