Exam 6: Learning

An investigator presents a conditioned stimulus followed by an unconditioned stimulus until an animal is classically conditioned.Then she exposes the animal to an extinction procedure.If she waits a while and then tests the animal again,she is likely to see

An event that decreases the probability of a response is known as

Of the following,a behaviorist is most likely to study

Rats that have been shocked while drinking sweetened water from a tube that produces loud noises and bright lights will later

Suppose your alarm made a slight clicking sound just before the alarm goes off.Even though you didn't wake up to the clicking sound initially,now you do,due to classical conditioning.In this example,the unconditioned response is

A rat learns to press a lever to escape from an electric shock.This is an example of ____________________. negative reinforcement

Shaping (in the context of operant conditioning)means

The more lottery tickets you buy,the greater your chances of winning.However,you have no way of knowing how many tickets you will have to buy before you win.It might be fewer than ten;it might be more than a million.This is an example of which type of schedule of reinforcement?

Charles Darwin's theory of evolution inspired psychologists of the early 1900s to study

A dog is conditioned to salivate when it hears a tone of one pitch and not to salivate to a second pitch.This effect is called

Shaping (in the context of operant conditioning)means

In order to reduce risky behavior of children on a playground,a safety officer offered rewards to the entire class if everyone played more safely.Researchers found this program

The disequilibrium principle states that:

Repeatedly presenting the CS without the UCS leads to the extinction of the CR.

Which type of experience must a subject go through in classical conditioning before it can display stimulus generalization?

You watch someone win election as President of the United States.You would like to win that honor too,but you make no effort to copy the actions of the person who won the election.If you are like most people,the probable reason why you failed to imitate this person is that

An individual receives a reinforcement after a certain number of responses.Sometimes 5 responses are necessary,sometimes 2,and sometimes 10.This is an example of which type of schedule of reinforcement?

Which of the following statements about extinction following intermittent reinforcement is true?

In classical conditioning,learning is to unlearning as

After classically conditioning some response,how might one produce extinction of the response?
