How does perceptual set support Gregory's constructivist theory?

Perceptual set shows that perception is influenced by expectations and knowledge, not just sensory input. The effect fits the top-down view of perception.

How can motivation affect perceptual set?

A strong need or desire makes people more likely to notice things linked to it. A hungry person is quicker to notice food.

What did Gilchrist and Nesberg (1952) find about motivation and perception?

Participants who had gone without food rated pictures of food as brighter than participants who had eaten. Hunger made food-related stimuli stand out more.

How can expectation affect perceptual set?

People tend to see what the context leads them to expect. An ambiguous stimulus is interpreted to fit the surrounding information.

1
What is perceptual set?
