Question

​19.​Extinction, in classical conditioning terminology, refers to:​

a.

the generalization of a CR to many different stimuli, resulting in a constant UCR

b.

the unlearning of a CR via counterconditioning

c.

the disappearance of a CR when the CS is no longer paired with the UCS

d.

the forgetting of a UCR after a long time has elapsed

Answer 1

• ANSWER-.​Extinction, in classical conditioning terminology, refers to the disappearance of a CR when the CS is no longer paired with the UCS
• Extinction is when the occurrences of a conditioned response decreases or disappears. In classical conditioning, this happens when a conditioned stimulus is no longer paired with an unconditioned stimulus.
• For example, if the smell of food (the unconditioned stimulus) had been paired with the sound of a whistle (the conditioned stimulus), it would eventually come to evoke the conditioned response of hunger.
• However, if the unconditioned stimulus (the smell of food) were no longer paired with the conditioned stimulus (the whistle), eventually the conditioned response (hunger) would disappear.
