Essay on Early vs Late Selection Models of Attention

This essays aims are to compare and contrast early VS late selection models of attention and attentional control. Specifically, its focus will be on some of the theories and research put forward within this field of study, that using computer analogy terms have provided models to explain attention. Following a chronological structure a review of some of the most influential theories of selective attention will be compared those of Broadbent (1958) Treisman (1964) and Deutsh Deutsh (1970). It will be considered how well these models describe the mental processes involved in auditory attention and aid our understandings of how we can selectively attend to information within our environments. Before we begin to examine some of the†¦show more content†¦This model design does seem to relate well to (James) 1890, definition of the nature of consciousness and selection, filtering is done consciously, since people decide what they choose to listen to. It also proposes that filtering takes place early in information processing. One message is filtered in and the remaining are filtered out (except for their basic physical features). Messages filtered in receive further processing, while filtered out messages are eventually lost. Therefore this theory views filtering as a winner takes all process, in what is perceived and heard. According to Treisman (1960) attenuation model which modified Broadbent design. She agreed that the perceptual system has limited capacity, so anything that is not attended wont gain full perceptual processing. Yet an important difference in her model is that it incorporates an additional second attenuating filter and a dictionary analysis unit. It is also an early selection model based on physical characteristics of the information. Therefore the weakened message is still processed to some extent Information is briefly retained in a sensory register or buffer, and then undergoes analysis by the attenuation filter the main message gets through with other information. However, Treismans filter attenuates (weakens), rather than eliminates, the unattended information. A second selective filter processes the information that is attended to, whichShow MoreRelatedCompare and Contrast Early vs Late Selection Models of Attention.

How well do they explain how we selectively attend to information? Attention was described by William James (1890, cited in Eysenck amp; Keane, 2000, p130) as â€Å"the taking possession of the mind, in clear and vivid form , of one out of what seem several simultaneously possible objects or trains of thought.

There are many theories of visual and auditory attention that provide us with a greater understanding of the ways in which humans attend to different stimuli (Driver, 2001), such as Broadbent’s (1958) filter theory of attention for example.
