Example Questions
Example Question #1 : Operative Conditioning
American psychologist B.F. Skinner is best known for his work in operant conditioning.Like all great academics, Skinner was not without influence. His work was inspired primarily based on Thorndike's Law of Effect. This law states that behaviors paired with positive consequences/effects/rewards are likely to be repeated, while behaviors paired with unpleasant consequences/effects/rewards are likely to be avoided.
While this principal inspired Skinner, he researched it further and named this principle operant conditioning. Skinner's research showed that conditioning/learning could occur through the use of punishments and rewards. The two important concepts of operant conditioning include punishment and reinforcement. Finally, Skinner also discussed the possibility of a neutral operant, which neither increased nor decreased the likelihood of a behavior occurring.
A man wants to teach his puppy to sit. In order to teach the dog, the man tells the puppy "sit" and rewards her with a treat each time she does so successfully. Eventually, he also uses a hand signal while saying the word "sit." After some time, the dog begins to respond to both the word "sit" and to the hand signal. In this example, which of the following can be considered a secondary reinforcer?
The word sit
The treat
Both the word "sit", and the hand signal
The hand signal
Both the word "sit", and the hand signal
A secondary reinforcer is learned; therefore, it has no innately desirable attributes. On the other hand, a primary reinforcer is innately pleasing. In this example, the treat is innately pleasing to the dog, and is the primary reinforcer. Both the word "sit", and the hand signal have been paired to each other, as well as to the treat. Because they have been paired to the treat (i.e. the primary reinforcer) they have become secondary reinforcers.
Example Question #1 : Identifying Positive And Negative Reinforcement
American psychologist B.F. Skinner is best known for his work in operant conditioning.Like all great academics, Skinner was not without influence. His work was inspired primarily based on Thorndike's Law of Effect. This law states that behaviors paired with positive consequences/effects/rewards are likely to be repeated, while behaviors paired with unpleasant consequences/effects/rewards are likely to be avoided.

Skinner's research showed that conditioning/learning could occur through the use of punishments and rewards. The two important concepts of operant conditioning include punishment and reinforcement. Finally, Skinner also discussed the possibility of a neutral operant, which neither increased nor decreased the likelihood of a behavior occurring.
In operant conditioning, what is the term used to describe taking away a desired stimulus in order to decrease the likelihood of a behavior occurring?
Negative punishment
Positive reinforcement
Negative reinforcement
Positive punishment
Negative punishment
Reinforcement always acts to increase the likelihood of a behavior occurring; therefore, "positive reinforcement" and "negative reinforcement" can be eliminated. "Positive punishment" acts to add an undesirable stimulus in order to decrease the likelihood of a behavior occurring. On the other hand, "negative punishment" acts to remove a desired stimulus to reduce the likelihood of a behavior occurring, like the question asks.
