Exam 4: Theories of Conditioning

Based on the Rescorla-Wagner model, if the US intensity is increased in the second phase of conditioning, when L is added to a previously conditioned T in a blocking experiment, then the

Jesse thinks that signaling the start and end of everything in an experiment will facilitate learning. He arranges two groups of animals in a learning experiment. In Group A a light is followed by a shock. In Group B the light is followed by a shock, which is then followed by a tone to signal that the shock is over. He expects Group B to learn better than Group A because the events are better signaled. What would Wagner's short-term memory model predict here? Why?

Research on latent inhibition and habituation has demonstrated that

We associate events represented in short-term memory when they

Contextual stimuli are likely to be most predictive of the US when the contingency between the CS and US is

A preexposed CS conditions more slowly than a novel CS. How does the Rescorla-Wagner model account for this result?

Would the Pearce-Hall predict protection from extinction? Why or why not?

According to Wagner's SOP model of conditioning,

For a rat, a light is conditioned to asymptote such that it is very strongly associated with food. The rat is then kept in a cage until he is hungry, and this time the light comes on at the same time as a tone. Which statement is correct?

Two stimuli are inhibitors and predict no US. If they are combined with a third CS without the US, the third CS will

According to the Rescorla-Wagner model, protection from extinction is most likely to occur when

An experimenter conducted an experiment with pigeons. Group 1 produced 28 key pecks and Group 2 produced 72 key pecks. He then simulated the experiment with Wagners SOP model and found it to predict that Group 1 would produce 34 key pecks and Group 2 would produce 64. He concluded that the model is wrong. How is his reasoning faulty?

Describe how the AESOP model could predict that a person knows he or she is safe from danger and yet still feels fear.

According to _______, one's attention to predictive stimuli increases the more predictive these stimuli become.

The priming model assumes that

According to the Rescorla-Wagner model, _______ determines the amount that can be learned.

The Rescorla-Wagner model predicts that when a CS is preexposed,

Driving in Spain, you quickly learn that a yellow box on the roadside indicates that radar equipment and a camera are ahead and that a green box on the roadside indicates that radar and a camera can be expected only about half the time. Upon crossing the border into France, you see both a yellow and green box on the side of the road, and you stare at the yellow box while you slow down. This time, no radar equipment appears, but a police car is sitting on the road ahead. Therefore, in France a green box leads you predict the police car more than a yellow box does. This overall pattern of behavior in the new country is consistent with which theory of attention? Justify your answer.

Which set of symbols is used to represent the surprisingness of the US?

According to the Rescorla-Wagner model, the US becomes less effective on each subsequent conditioning trial because the subject
