Exam 4: Classical Conditioning

Thirsty pigeons are presented with keylight-water pairings and begin to peck the keylight.Once keypecking develops, the birds are allowed to drink freely.Their keypeck behavior drops off dramatically.This suggests their response to the key is mediated by

What is the blocking effect? Provide two theoretical mechanisms for the blocking effect.

A major difference between attentional models and the Rescorla-Wagner model is described by which of the following choices?

Using the Rescorla-Wager model, predict ∆V of stimulus B during conditioning trials with compound stimulus A/B when the associative value of A at the beginning of the trial is lambda and the associative value of B at the beginning of the trial is lambda.

In what respects are attentional theories of learning different from other theories?

Which of the following regions organizes active defensive behaviors needed for fight and flight?

Your friend plans to autoshape her goldfish to swim up to a hoop (the CS).You recommend using a US that

Which of the following is a function of preexposure to the CS or the US?

Which of the following is a challenge to the stimulus substitution model?

Detail how the CS, the US, and the timing of the presentation of these stimuli can affect classically conditioned responding.

According to the Rescorla-Wagner model, extinction is which of the following?

Lesioning the amygdala results in

Which is true in a sensory preconditioning experiment?

A rat is given 20 exposures to a red light cue.Then, the red light is presented paired with food delivery.Compared to a rat that did not receive the initial 20 exposures, this rat took a long time to develop a CR to the red light.The slower learning is due to

US-devaluation experiments suggest that for many first-order conditioning procedures, which of the following is true?

Using the Rescorla-Wager model, predict ∆V of stimulus B during conditioning trials with compound stimulus A/B when the associative value of A at the beginning of the trial is 1/2 lambda and the associative value of B at the beginning of the trial is 1/2 lambda.

The Rescorla-Wagner model assigns the associative value of to a stimulus that is a fully conditioned inhibitor.

Attempts to sexual condition fish and quail suggest

Belongingness effects have been demonstrated to reflect which of the following?

Compare the relative-waiting-time hypothesis and the comparator hypothesis.Include the similarities and differences of the theories and each theory's strengths and weaknesses.
