Feature Integration Theory - features involved divided...

Feature Integration Theory (Treisman & Gelade, 1980, Treisman, 1992. 1993)
theory of attention and perceptual processing
a) sometimes process all parts of a scene in parallel (at the same time)
b) sometimes process parts of the scene serially (one at a time)
respectively, testing two types of processing:
a) processing that involves divided attention (automatic registration of features in
parallel)
b) processing that requires focused attention (a more demanding kind of
processing that is required when objects are more complex)
respectively, using two types of stimulus situations to test two different types of
processing:
a) isolated features T I Y
b) combination features T I Z
Treisman and Gelade (1980) hypothesized that if isolated
