Critical Thinking Exercise
�
What is the most
important thing you have learned outside of a classroom?� Why?
Learning
�
Any relatively
permanent _____________ in behavior brought about by experience.
� Classical
Conditioning
� Operant
Conditioning
� Cognitive
Learning
� Observational
Learning
Classical Conditioning
�
Learning to make
a ___________ response to a stimulus other than the original, natural stimulus
that normally produces the reflex.
Ivan Pavlov
� Russian physiologist (person who studies the workings
of the body) who discovered __________________ through his work on digestion in
dogs.
Pavlov�s Observation (1926)
�
Studied digestion
in dogs
� Presented
meat powder and measured salivation
� Dogs
started salivating ____________ food was presented
� Why?
Pavlov�s Experiment: Phase 1
�
Food (US):
salivation (UR)
� Reflexive
response
�
Tone: nothing
Pavlov�s Experiment: Phase 2
�
CS is repeatedly
paired with the US
� A
tone is sounded before the food is presented
� Acquisition
Pavlov�s Experiment: Phase 3
�
Eventually, the
CS elicits a new CR
� Classical
conditioning is complete when hearing the tone by itself causes salivation
Classical Conditioning Concepts
� Unconditioned stimulus (UCS) - a _______________________ stimulus that leads to an
involuntary response.
� Unconditioned
means �______________� or �naturally occurring.�
� Unconditioned response (UCR) - an __________________ response to a naturally occurring
or _______________ stimulus.
� Conditioned stimulus (CS) - stimulus that becomes able to produce a learned
reflex response by _________________________ the original unconditioned
stimulus.
� Conditioned response (CR) - learned ________________ response to a conditioned
stimulus.
� The
CR behavior is always the _________ behavior as the UR.�
What distinguishes them is what they occur _____________ to (US vs. CS).
Classical Conditioning: A More Relevant Example

� Conditioned Stimulus =
� Conditioned Response =
��Conditions� for
Classical Conditioning
�
The CS must come _____________
the UCS.
�
The CS and UCS
must come _________________________ in time�ideally, only several seconds
apart.
�
The neutral
stimulus must be paired with the UCS _____________ times, often many times,
before conditioning can take place.
�
The CS is usually
some stimulus that is _______________ or stands out from other competing
stimuli.
Classical Conditioning Concepts
�
Stimulus
generalization - the tendency to
respond to a stimulus that is only _________________ to the original
conditioned stimulus with the conditioned response.
� Stimulus discrimination - the tendency to stop making a _____________
response to a stimulus that is _____________ to the original conditioned
stimulus because the similar stimulus is never paired with the unconditioned
stimulus.
� Extinction -
the ________________ or weakening of a learned response following the removal
or absence of the unconditioned stimulus (in classical conditioning) or the
removal of a reinforcer (in operant conditioning).
� Spontaneous recovery � the _________________ of a learned response after extinction has
occurred.
� Learning
is a relatively permanent change in behavior.
�
Higher-order
conditioning - occurs when a strong
conditioned stimulus is paired with a neutral stimulus, causing the neutral
stimulus to become a _______________ conditioned stimulus.
Conditioned Emotional Response
�
Conditioned
emotional response (CER) - emotional
response that has become _____________________________ to occur to learned
stimuli, such as a fear of dogs or the emotional reaction that occurs when
seeing an attractive person.
� CERs
may lead to phobias � irrational ___________ responses.
The Case of �Little Albert�
� �Little Albert� was conditioned to fear a
_________________ and other similar stimuli (Watson & Rayner, 1920)
Other Conditioned Responses
� Vicarious conditioning - classical conditioning of a reflex response or
emotion by watching the ______________ of another person (Bandura &
Rosenthal, 1966).
� Conditioned taste aversion - development of a ___________________ or aversive
response to a particular taste because that taste was followed by a nausea
reaction, occurring after only one association (Garcia & Koelling, 1966).
� Biological
Preparedness - tendency of animals to learn certain associations, such as
taste and nausea, with only one or few pairings due to the ___________________
of learning (Gustavson et al., 1976)
Operant Conditioning
�
Operant
conditioning - the learning of _______________
behavior through the effects of pleasant and unpleasant ___________________ to
responses (Skinner, 1938).
�
Thorndike�s
Law of Effect - law stating that if a
response is followed by a pleasurable consequence, it will tend to be ___________________,
and if followed by an _________________ consequence, it will tend not to be
repeated (Thorndike, 1911).
B.F. Skinner�s Contribution
� Behaviorist; wanted to study only _____________,
measurable behavior.
� Gave �operant conditioning� its name.
� Operant
- any behavior that is _______________.
� Learning depends on what happens ____________ the
response � the consequence.
Skinner�s Rats
Operant Conditioning Concepts
Reinforcement
�
Reinforcement - any event or stimulus, that when following a
response, __________________ the probability that the response will occur
again.
� Positive
reinforcement - the reinforcement of a response by the addition or
experiencing of a __________________ stimulus.
� Negative
reinforcement - the reinforcement of a response by the removal, escape
from, or avoidance of an ______________ stimulus.
�Types of Reinforcers
� Primary reinforcer - any reinforcer that is ______________ reinforcing by meeting a basic
biological need, such as hunger, thirst, or touch.
� Secondary reinforcer - any reinforcer that becomes reinforcing after being paired with a _____________________,
such as praise, tokens, or gold stars.
Punishment
�
Punishment - any event or object that, when following a
response, makes that response _____________________ to happen again.
� Punishment
by application - the punishment of a response by the addition or
experiencing of an ________________ stimulus.
� Punishment
by removal - the punishment of a response by the removal of a
________________ stimulus.
How to Make Punishment More Effective
�
Punishment should
________________________ the behavior it is meant to punish.
�
Punishment should
be ________________.
�
Punishment should
be _________________ aversive.
�
Punishment of the
wrong behavior should be paired, whenever possible, with reinforcement of the ____________________.
Negative Reinforcement vs. Punishment
�
Negative reinforcement
________________ the likelihood of a behavior, whereas punishment
_________________ the likelihood of a behavior.
Other Operant Conditioning Concepts
�
Shaping - the reinforcement of ___________________ in
behavior that lead to a desired, more complex behavior.
� Successive
approximations - small steps in behavior, one after the other, that lead to
a particular goal behavior.
�
Extinction � occurs if the behavior (response) is not _______________.
�
Operantly
conditioned responses also can be generalized to stimuli that are only ______________
to the original stimulus.
�
Spontaneous
recovery (reoccurrence of a once ___________
response) also happens in classical conditioning.
Schedules of Reinforcement
� Fixed ratio schedule of reinforcement - schedule of reinforcement in which the number of ________________
required for reinforcement is always the same.
� Variable ratio schedule of reinforcement - schedule of reinforcement in which the number of
responses required for reinforcement is _________________ for each trial or
event.
� Fixed interval schedule of reinforcement - schedule of reinforcement in which the interval of
time that must pass before reinforcement becomes possible is always the
______________.
� Variable interval schedule of reinforcement - schedule of reinforcement in which the interval of
____________ that must pass before reinforcement becomes possible is different
for each trial or event.
Behavior Modification
�
Behavior
modification - the use of
_____________________ techniques to bring about desired changes in behavior.
�
Token economy - type of behavior modification in which desired
behavior is _________________ with tokens.
� Time-out - a
form of _______________________ by removal in which a misbehaving animal,
child, or adult is placed in a special area away from the attention of others.
� Applied behavior analysis (ABA)
� modern term for a form of behavior modification that uses ________________
techniques to mold a desired behavior or response (Lovaas, 1964).
Cognitive Learning
Cognitive Learning Theory
�
Early days of learning
� focus was on _______________.
�
1950s and more
intensely in the 1960s, many psychologists were becoming aware that ______________,
the mental events that take place inside a person�s mind while behaving, could
no longer be ignored (Kendler, 1985).
Latent Learning
�
Edward Tolman�s
best-known experiments in learning involved teaching three groups of rats the
same maze, one at a time (Tolman & Honzik, 1930).
� Group
1 � rewarded each time at end of maze.
� Learned maze quickly.
� Group
2 � in maze every day; only rewarded on 10th day.
� Demonstrated learning of maze almost immediately after
receiving reward.
� Group
3 � never rewarded.
� Did not learn maze well.
�
Latent
learning - learning that remains
____________ until its application becomes useful.
Learned Helplessness
� Learned helplessness - the tendency to fail to act to escape from a situation because of a
history of repeated ________________ in the past (Seligman, 1975).
Insight
�
Insight - the _______________ perception of relationships
among various parts of a problem, allowing the solution to the problem to come
quickly (Kohler, 1925).
� Cannot
be gained through trial-and-error learning alone.
� �__________�
moment.
Observational Learning
�
Observational
learning - learning new behavior by
watching a _________ perform that behavior.
�
Learning/performance
distinction - referring to the
observation that learning can take place without actual ________________ of the
learned behavior.
Albert Bandura�s Famous BoBo Doll Experiment (1961)
� Two Groups
� Group

2: models played aggressively
� Children _________________ the actions of the model
they saw
Four Elements of Observational Learning
� ATTENTION -

learner must also be able to ______________________ of what was done, such as
remembering the steps in preparing a dish that was first seen on a cooking
show.
� IMITATION -
The learner must be capable of ___________________, or imitating, the actions
of the model.
� MOTIVATION -
Finally, the learner must have the ________________ to perform the action.
