Suppose that you are running to catch a subway. You race past a large poster that shows various foods in uncharacteristic colors, such as an orange strawberry and a red carrot. However, you actually perceive a red strawberry and an orange carrot.

In Anne Treisman's theory, this phenomenon would be called:

a. overactive bottom-up processing.

b. attentional bias.

c. a Gestalt.

d. an illusory conjunction.
