Attention is the behavioral and cognitive process of selectively concentrating on a discrete aspect of information, whether deemed subjective or objective, while ignoring other perceivable information.Areas of active investigation involve determining the source of the sensory cues and signals that generate attention, the effects of these sensory cues and signals on the tuning properties of sensory neurons, and the relationship between attention and other behavioral and cognitive processes like working memory and vigilance.A relatively new body of research, which expands upon earlier research within neuropsychology, is investigating the diagnostic symptoms associated with traumatic brain injuries and their effects on attention. The relationships between attention and consciousness are complex enough that they have warranted perennial philosophical exploration.The term "spotlight" was inspired by the work of William James, who described attention as having a focus, a margin, and a fringe.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.It is the taking possession by the mind in clear and vivid form of one out of what seem several simultaneous objects or trains of thought.Focalization, concentration of consciousness are of its essence.Generally speaking, visual attention is thought to operate as a two-stage process.In the first stage, attention is distributed uniformly over the external visual scene and processing of information is performed in parallel.Due to this, many of the discoveries in the field of Attention were made by philosophers.Psychologist John Watson cites Juan Luis Vives as the Father of Modern Psychology due to his book De Anima et Vita ("The Soul and Life") in which Vives was the first to recognize the importance of empirical investigation.
