Kingston Powers · Answer 1

(a) the prevalence of illusory conjunctions

Explanation:

According to the Feature integration theory, which was developed by Anne Treisman and Garry Gelade in 1980, and later further advanced in experiments together with Hilary Schmidt in 1982, individuals register features of objects 'early, automatically and in parallel', for example color of a vehicles (green car vs. red truck), while they identify objects later and separately (car vs. truck).

That is why, when people are quickly presented with objects (passing vehicles), they may misinterpret allocation of their features later. Here, they could report that the car was red, while the truck was green. This phenomenon is called Illusory conjunctions. It occurs because features, such as shapes and color, in human perception exist separately and later can be swapped during reporting of the experience.
