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).
Transient attention is a short-term response to a stimulus that temporarily attracts or distracts attention. Researchers disagree on the exact amount of the human transient attention span, whereas selective sustained attention, also known as focused attention, is the level of attention that produces consistent results on a task over time.
Specifically, research on attentional capture has two modes: voluntary and reflexive. The voluntary mode is a top down approach where attention is shifted according to high-level cognitive processes. The reflexive mode is a bottom up approach where attention shifts involuntarily based on a stimulus's attention attracting properties. [40]
“In today's world, we are constantly bombarded by distractions, and many habits make it even harder to stay focused,” says Kiki Ramsey, founder of Positive Psychology Coaching and the ...
The scarcity of attention is the underlying assumption for attention management; the researcher Herbert A. Simon pointed out that when there is a vast availability of information, attention becomes the more scarce resource as human beings cannot digest all the information. [6] Fundamentally, attention is limited by the processing power of the ...
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.
Monotropism is an individual's tendency to focus their attention on a small or singular number of interests at any time, with them neglecting or not perceiving lesser interests. This cognitive strategy has been posited as the central underlying feature of autism .
For example, pre-attentive processing is slowed by sleep deprivation while attention, although less focused, is not slowed. [6] Furthermore, when searching for a particular visual stimulus among a variety of visual distractions, people often have more trouble finding what they are looking for if one or more of the distractions is particularly ...
