Question 2

Feature Integration Theory (FIT)

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

Answer 2

– 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

Question 3

Supervisory attention system (SAS)
Norman + Shallice

3 diff levels of automaticity

Answer 3

1) Fully automatic
2)Partially automatic- contention scheduling - to resolve conflicts between schemas - but without deliberate direction or conscious control
3) Deliberate control by SAS e.g: new tasks

Question 4

Often associated with frontal lobe damage

Utilization behaviour. p.p will utilize any object presented to them
