Question :
11. Pavlov’s dog upset. Pavlov keeps ringing the buzzer but puts : 1201949
11. Pavlov’s dog is upset. Pavlov keeps ringing the buzzer but puts no meat powder in its mouth. The dog no longer salivates to the sound. A few weeks later the lab assistant begins once again to put meat powder in the dog’s mouth and ringing the buzzer. After only two or three pairings, the dog is once again salivating to the buzzer. This is an example of
A. reconditioning.
B. stimulus generalization.
C. spontaneous recovery.
D. higher order conditioning.
12. Dr. Evil presents the sound of a buzzer to his pet rabbit, and he follows it with the delivery of a small electric shock. After repeated pairings of the buzzer and shock, the rabbit learns to fear the sound of buzzers. Dr. Evil then proceeds to extinguish the rabbit’s fear of buzzers. Now suppose that, after extinction, Dr. Evil decides to present the buzzer and shock to the rabbit once again. After only a few pairings, the rabbit will demonstrate _____ and fear the buzzer again.
A. stimulus discrimination
B. spontaneous recovery
C. stimulus generalization
D. reconditioning
13. Pavlov trained his dog, Sparky, to salivate when he heard a bell. Before leaving on his Jamaican vacation, Pavlov extinguished the salivation response. When Pavlov returned two weeks later, he accidentally knocked the bell off the table, causing it to ring. He noticed that Sparky was salivating in response to the ringing bell. This example best illustrates
A. reconditioning.
B. stimulus generalization.
C. spontaneous recovery.
D. higher-order conditioning.
14. On September 1, Central High School’s fire alarm sounded, and students ran in fear from the burning chemistry lab. During the next few weeks, there was a rash of false alarms, and people began to ignore the fire bells. On December 15, the fire alarm sounded, and students once again ran from the building in fear. What phenomenon was responsible for the students’ renewed fear?
A. Spontaneous recovery
B. Reconditioning
C. Generalization
D. higher order conditioning
15. A child who has a conditioned fear response toward Santa Claus reacts with fear toward any gentleman with a white (or gray) beard. This phenomenon is known as
A. acquisition.
B. stimulus discrimination.
C. stimulus generalization.
D. reconditioning.
16. Han is fearful of the powerful Jabba. Han becomes fearful when he hears Jabba’s low voice, but also becomes fearful when he hears any low voice. What phenomenon best explains Han’s tendency to become fearful when hearing any low voice?
A. Extinction
B. Reconditioning
C. Stimulus generalization
D. Stimulus discrimination
17. Ned is very afraid of the bats that fly around his house at night, but he is not at all afraid of the birds that fly around his house during the day. Ned’s fear of bats does not extend to all flying creatures because of
A. higher order conditioning.
B. stimulus discrimination.
C. secondary reinforcement.
D. stimulus generalization.
18. A dog in a classical conditioning experiment salivates to a buzzer but not to a bell. This is an example of
A. stimulus generalization.
B. partial reinforcement effect.
C. secondary reinforcement.
D. stimulus discrimination.
19. Classical conditioning works best when the conditioned stimulus _____ the unconditioned stimulus.
A. precedes
B. occurs at the same time as
C. follows
D. is presented a long time before or after
20. Betsy wants to train her dog to do several tricks. She checks out a book on dog training that includes a chapter on how to use classical conditioning. Betsy learns that a dog is least likely to learn a conditioned response when the
A. unconditioned stimulus is strong.
B. conditioned stimulus precedes the unconditioned stimulus.
C. time interval between the conditioned stimulus and the unconditioned stimulus is under one minute.
D. conditioned stimulus predicts many different stimuli.
