During the first section of the test, the objective is to measure attention during a boring task. For adults, this section is 10.8 minutes long and the non-target is presented 3.5 times for every 1 time a target is presented. The second section of the test is a measure of attention while attending to a stimulating task (target frequent).
A psychomotor vigilance task (PVT) is a sustained-attention, reaction-timed task that measures the consistency with which subjects respond to a visual stimulus.Research indicates increased sleep debt or sleep deficit correlates with deteriorated alertness, slower problem solving, declined psychomotor skills, and increased rate of false responses.
In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time. [1] During this time, the person attempts to detect the appearance of a particular target stimulus. The individual watches for a signal stimulus that may occur at an unknown time. [2]
During a period of attention something like inhibition (i.e. inhibition to continue) rises and the rise is linear (linear) with a slope a 1 and during distraction periods the inhibition decreases and also the decrease is linear with slope a 0. This process of increasing and decreasing inhibition can be described as a random oscillator.
Attentional control, commonly referred to as concentration, refers to an individual's capacity to choose what they pay attention to and what they ignore. [1] It is also known as endogenous attention or executive attention. In lay terms, attentional control can be described as an individual's ability to concentrate.
The Wide Range Assessment of Memory and Learning (WRAML), currently in its third edition (WRAML3), is a standardized test that measures an individual's memory functioning. . It evaluates both immediate and delayed memory ability along with the acquisition of new learning.
Divisibility is when attention is divided among tasks [citation needed]. The ability to jump attention from one task to the next is known as shift-ability. Maintaining attention on one task for an extended amount of time is referred to as the sustainability of attention. The SAS also accounts for the priming of anticipated tasks.
The Cattell–Horn–Carroll theory factors that this test examines are based on 9 broad stratum abilities, although the test is able to produce 20 scores [4] only seven of these broad abilities are more commonly measured: comprehension-knowledge (Gc), fluid reasoning (Gf), short-term memory (Gsm), processing speed (Gs), auditory processing (Ga), visual-spatial ability (Gv), and long-term ...
