This article focuses mainly on the selective attention. This is a set of process that allows selection of some stimuli over others and the performance of multiple tasks in a coordinated manner. Visuospatial attention is the process that select visual stimuli based on their spatial location (Wu, 2007). Therefore, spatial attention refers to the most widely studied variety of attention in normal population and neurologic populations. Attentional process is used to protect an organism from information overload and is selective in that they allow some processes of some stimuli while disregarding others. Thus, attention can be referred to as the process that permits an organism to choose some environmental inputs over the others. The term “attention” appears in everyday language, but this initiative which folk psychology use does not provide facts on the definition of solid. Task defined attention does not explain the process that permit the selection to occur. For example, when an observer views two spatially adjacent letters, red and green, and asked to report the red letter (LoBosco City University of New York, 2006). Although this task requires the observer to pay maximum attention to the red letter, it does not eliminate the mechanism of attention, such as whether or not if they attended letter is facilitated relative to the unattended letter, whether or not the unattended letter is inhibited average to the attended letter or both. Li The University of Wisconsin- Madison (2008) assert that a process oriented definition of attention proposes how attention allows the red letter so that to be attended and reported and how the green light is unattended. For instance, the most well known process oriented definition of attention comes from Williams James, who defined attention as the process that involve s withdrawal from some things in order to deal effectively with others. According to James, attention restricts processing items over others and allows the attended item to become more salient. He relays on the process oriented definition of attention and consider mechanisms that allow observers to select one spatial location over other locations. Initially, understanding the operation of spatial attention in neurologically normal observers can help guide assessment in brain damage patients. Through knowing the process of spatial attention, disruption may be of much significance for developing assessment techniques or care giving strategies and rehabilitation. The whole process involves selecting a stimulus on the basis of its spatial location. The place occupied by the item is selected and then receives further cognitive processing (Li The University of Wisconsin- Madison, 2008). Visuospatial attention also intersects with much other attentional process. For instance, it can sele ct groups of items, based on how they adhere or grouped together. This form of selection has being referred as object formed selection. This spatial attention is closely associated with early processing, before stimulus identity is known. Attention is directed to a location in which visual space and an item is identified, through facilitating the perception or binding the features of that item. There are many varieties of attention and attentional selection. Attentional mechanisms operate earlier and others later in this framework.
