Exam 4: Classical Conditioning: Learning to Predict Important Events

Which is true about the Rescorla-Wagner model?

Jeff's dog salivates when he goes to the cupboard to get a dog biscuit.What is the unconditioned stimulus?

Which of the following demonstrates classical conditioning?

Recordings of activity in the _____ during eyeblink conditioning in rabbits show activity that occurs _____ the response is made.

When researchers gave animals an injection of an inert placebo to pre-expose them to the contextual cues associated with drug use,they found that the animals:

The eyeblink CR seems to:

A regular drug user can have an elevated reaction to his usual drug if he takes that drug in a new environment.In this example,the familiar environment in which the drug is normally taken is a:

In the Rescorla-Wagner model,the expectation of the US is described by the:

The difference between whether an animal expects the US and whether the US actually occurs is known as:

Lightning is usually followed by thunder.Eventually we can be startled just by the lightning alone.What is the unconditioned response?

In the Rescorla-Wagner model,an associative weight of 50 would indicate that the CS predicts the US ______ of the time.

Dionne compete on her high school's track team.She always feels naturally nervous right before a race.She also noticed that on days when she is not racing,just seeing the track still made her feel nervous.Her nervousness at seeing the track on non-race days is a(n):

Removing the ______ abolishes conditioned responses.

Some pet owners use a "clicker" device to train their pets.For example,if a cat owner wants her cat to stay off the bed,she might make a "click" sound with a clicker whenever the cat gets on the bed,and follow it shortly by a squirt of water to the cat.In this example,identify the CS,US,CR,and UR.

Consider a blocking experiment,in which an animal is first conditioned to associate a light with shock,and then is presented with a tone and light together followed by shock.According to CS modulation theories such as that of Makintosh,blocking would occur because the:

The _____ has/have different subregions for each kind of sensory stimulation.

Suppose we pair just a tone with a shock for many trials until the CR is reliably elicited by the tone,then we pair the tone plus a light with a shock.According to the Rescorla-Wagner model,at the end of the second phase of training:

Which of the following has been viewed as evidence of an error-correction mechanism in the brain?

In the Rescorla-Wagner model,if the associative weight for CS₁ is 20 and the associative weight for CS₂ is 30,then the expectation of the US is:

It has been suggested that drug addicts should use small amounts of their drug during therapy to extinguish their habit.This is because:
