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).

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.
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.
Focused attention: The ability to respond discretely to specific sensory stimuli. Sustained attention (vigilance and concentration): The ability to maintain a consistent behavioral response during continuous and repetitive activity. Selective attention: The ability to maintain a behavioral or cognitive set in the face of distracting or ...
The WRAML3 is composed of two verbal, two visual, and two attention-concentration subtests, yielding a Verbal Memory Index, a Visual Memory Index, and an Attention-Concentration Index. Together, these subtests yield the General Memory Index. [1]
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]
Directed attention fatigue (DAF) is a neuro-psychological phenomenon that results from overuse of the brain's inhibitory attention mechanisms, which handle incoming distractions while maintaining focus on a specific task. The greatest threat to a given focus of attention is competition from other stimuli that can cause a shift in focus.
