Compare and Contrast Early and Late Selection Models of Attention
Attention is a person’s ability to pay interest to certain things and ignore other things. Attention can also be described as a conscious human selection of certain things (Gazzaniga, Ivry, ; Mangun, 2013). The goals and objectives of a person or the relevance of the object may influence this selection process. Early selection models of attention focus on the physical features of a specific object which may include the size and color of the object where else late selection models focus on more complex features of the object (Gazzaniga, Ivry, ; Mangun, 2013).
A common feature of the early and the late models of attention is that they both process information consciously (Nobre ; Kastner, 2013). People make decisions regarding what choices and selections they make after consciously processing information. These models also process all information regarding a specific stimulus. Information on a specific stimulus is processed either intentionally or unintentionally then filtering process of the information occurs which involves analyzing the processed information and a decision to select the useful information is made (Nobre ; Kastner, 2013).

Early selection model of attention happens first before the late model of attention (Nobre ; Kastner, 2013). This is because early selection models detect the physical features of a stimulus, which are the first to be observed and easily accessible. An external stimulus is unconsciously processed automatically and analyzed based on the physical features of the stimuli. Late models of attention involve processing of stimuli that was unintended and may include watching or listening to the specific stimuli. This means paying more attention to the stimuli or object (Nobre ; Kastner, 2013).

Late selection model of attention selects information after processing which is different in early selection models of attention where selection happens before processing which is based on physical features of the external stimuli then proceed to select the important information (Gazzaniga, Ivry, ; Mangun, 2013). Late selection model of attention process unintended stimuli and analyze it then select the useful information. Information is selected based on characteristics that are more complex as more complex features of a stimulus are processed (Gazzaniga, Ivry, ; Mangun, 2013).
