AP PSYCHOLOGY

Detailed explanation-1: -A discriminative stimulus is the antecedent stimulus that has stimulus control over behavior because the behavior was reliably reinforced in the presence of that stimulus in the past. Discriminative stimuli set the occasion for behaviors that have been reinforced in their presence in the past.

Detailed explanation-2: -Antecedent is also something that comes before a behavior and is sometimes referred to as a trigger.

Detailed explanation-3: -A discriminative stimulus is a stimulus that when it is present, generates a particular response and the response is usually faster, more frequent, and more resistant to extinction. The responding behavior is then subjected to discriminative stimulus control.

Detailed explanation-4: -A conditioned stimulus, on the other hand, produces the response, while the discriminative stimulus signals the opportunity to respond. For example, if a bell tone were the conditioned stimulus, discrimination would involve being able to tell the difference between the bell sound and other similar sounds.

Detailed explanation-5: -In operant conditioning, a discriminative stimulus is defined as a(n): environmental stimulus or cue in the presence of which a particular response is more likely to be reinforced.
