Identify the unconditioned stimulus (US), the unconditioned response (UR), the conditioned stimulus (CS), and the conditioned response (CR).
1) The door to Jim's house squeaks loudly when he opens it. Jim's dog is happy and wags her tail. Soon, Jim's dog begins wagging its tail when the door squeaks.
(US) door, (UR) happy, (CS) squeaky door, (CR) wagging tail
2) To discourage her cat, Mittens, from jumping up on the couch in the living room, Katie sprays an annoying ammonia scent on the couch whose smell causes Mittens to wrinkle her nose and experience a sense of nausea. Later, Mittens avoids jumping up on the couch.
(US) ammonia scent, (UR) wrinkle nose and feel nauseous, (CS) couch, (CR) jump
Is this correct?
correct.
No, your answer for the second scenario is incorrect.
For the first scenario:
- The unconditioned stimulus (US) is the door squeaking.
- The unconditioned response (UR) is the dog being happy and wagging its tail.
- The conditioned stimulus (CS) is the squeaky door.
- The conditioned response (CR) is the dog wagging its tail when the door squeaks.
For the second scenario:
- The unconditioned stimulus (US) is the ammonia scent.
- The unconditioned response (UR) is Mittens wrinkling her nose and feeling nauseous.
- The conditioned stimulus (CS) is the couch.
- The conditioned response (CR) is Mittens avoiding jumping up on the couch.
So, the correctly identified answer is:
(US) ammonia scent, (UR) wrinkle nose and feel nauseous, (CS) couch, (CR) avoid jumping.
