So far , we have
focused on the spec - auditory aspects of attention , but the whole sensory
experience that is controlled by the direction of attention . Tresimen
and julesz hypothesized that two different processes work in visual attention .
In
the first stage there pross aawal , praatentif processes that scan the visual
field and quickly detect the main features of objects , such as size , color ,
orientation ( direction ) , and movement . if
any . Then
, according to treismen , the characteristics of the different encoded in the
map feature (feature map ) , located in different areas in the cortex . Since
the appearance of the original idea Broadbent of attention in the 1950s , which
not only affect a generation of researchers ( including Treisman ) , but it is
also important for the development of a limited -capacity information pemrosesa
models , a dozen or more theories have been proposed , which kesemuannya modify
or attacking ideas gagsan Broadbent . Unfortunately,
some experts consider broedbent theory wrong theory " one of two " ,
the theory that sees certain information processed canals or other channels . Characterizing such mistaken . Brodbent
( 1958 ) writes " once again we can not simply say " someone received
some information from the ear which does not even get full attention : even so
there are limits on the amount that can be processed , and the details are
ignored stimulsai dar ears , do not mind " . No
single theory of attention that can replace the original theory Broadbent ,
although a large number of studies have memantu clarify specific issues
involved in human attention .
