Q

Feature Integration Theory (FIT)

Treisman & Gelade (1980), Treisman (e.g., 1988,
1992)

A

– Rapid initial parallel process (“preattentive stage”)
* Process physical characteristics – “features”
* Targets that are identifiable by simple physical characteristic “popout”
– Then serial process (“focussed attention stage”)
* Features can be combined by focused attending to the location of
the object
* “Illusory conjunctions” (random combinations of features) can
occur due to problems in combining features to form objects at a
relatively late stage
* Slower than the parallel process, and depends on set-size
