This situation illustrates the concept of discrimination, which refers to the ability to distinguish between two or more stimuli and respond differently to each one. In this case, the pigeon is able to discriminate between the red disk (which it has learned to peck at) and the identical disk of any other color (which it ignores). Extinction refers to the gradual disappearance of a previously learned behavior when it is no longer reinforced. Avoidance training involves teaching an individual to avoid a particular behavior or stimulus to prevent negative consequences, while desensitization involves gradually exposing an individual to a feared stimulus or situation to reduce their anxiety or fear.
