Question:
During extinction, the __ is consistently omitted and the __ undergoes gradual reduction.
During extinction, the __ is consistently omitted and the __ undergoes gradual reduction.
Show Hint
Extinction weakens the conditioned response, but spontaneous recovery may occur if the CS is reintroduced after a rest period.

- CS, UCR
- UCS, UCR
- UCS, CR
- CS, CR

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In classical conditioning, extinction occurs when the conditioned stimulus (CS) is presented without the unconditioned stimulus (UCS) repeatedly. Over time, the conditioned response (CR) diminishes as the association weakens.
- Example: If a bell (CS) is rung but no food (UCS) follows, the salivation (CR) decreases.
