Many different tests on attention span have been used in different populations and in different times. Some tests measure short-term, focused attention abilities (which is typically below normal in people with ADHD), and others provide information about how easily distracted the test-taker is (typically a significant problem in people with ADHD).
Covert attention involves mental focus or attention to an object without significant eye movement, and is the predominant area of interest when using the Posner cueing task for research. By making 80% trials valid and 20% trials invalid, Posner encourages covert shifts of attention to take place in response to cueing.
Research has found that self-focused people that deem their rate of progress on a task unacceptable will be more likely to avoid the task goals and therefore escape states of task driven self-awareness. [10] On the other hand, people that deemed their efforts to diminish the self-standard discrepancy potentially effective were more likely to ...
N2pc refers to an ERP component linked to selective attention. [1] The N2pc appears over visual cortex contralateral to the location in space to which subjects are attending; if subjects pay attention to the left side of the visual field, the N2pc appears in the right hemisphere of the brain, and vice versa.
To focus, your brain needs oxygen, which is why taking several deep breaths when you first wake up can help improve your mental clarity. “You should always meditate and do breathwork in the ...
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.
The focus is an area that extracts information from the visual scene with a high-resolution, the geometric center of which being where visual attention is directed. Surrounding the focus is the fringe of attention, which extracts information in a much more crude fashion (i.e., low-resolution).

Attentional control, colloquially referred to as concentration, refers to an individual's capacity to choose what they pay attention to and what they ignore. [1]
