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.
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]
Posner and Cohen proposed three explanations for inhibition: inhibition results from having two alternative positions, inhibition could result from moving attention away from a cued stimulus back to the fixation point, and; inhibition may occur because the efficiency in some part of the pathway from the cued location is reduced by the cuing.
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.
Resource theory states that as each complex task is automatized, performing that task requires less of the individual's limited-capacity attentional resources. [46] Other variables play a part in our ability to pay attention to and concentrate on many tasks at once. These include, but are not limited to, anxiety, arousal, task difficulty, and ...

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 ...
