Transcript of Learning A relatively permanent change in behavior that occurs through experience.
Learning
A relatively permanent change
in behavior that occurs through experience.
Behavioralism
Psychological perspective that emphasizing the role of learning and experience in determining behavior. A strict behavioralist believes that babies are tabula
rasa and the study of psychology should focus purely on observable behaviors and not unobservable
thoughts.
How do we learn?Most learning is associative learning• Learning that certain events occur together.
Learning The process by which experience or practice results in a relatively permanent change in behavior or potential behavior
Classical ConditioningThe type of learning in
which a response naturally elicited by one stimulus becomes to be
elicited by a different formally neutral stimulus
Operant ConditioningThe type of learning in which behaviors are emitted to earn rewards or avoid punishments
Social Cognitive Learning Theory
The type of learning in which behaviors are learned by observing a model
Pavlov and Watson B.F. Skinner Albert Bandura
UCS, UCR, CS, CRReinforcement and
PunishmentModeling and Vicarious
Learning
We are here
Which is which?
1. A child is attacked by a dog. The child now fears all dogs.
2. You do your homework every night to get good grades and avoid punishment.
Classical – involuntary, stimulus precedes behavior
Operant – voluntary, stimulus follows behavior
Classical Conditioning
An INVOLUNTARY behavior is determined by what PRECEDES it.
Ivan Pavlov
Dogs must have LEARNED to salivate.
This is passive learning (automatic…learner does NOT have to think).-It does exist!
Unconditioned Stimulus (US): a stimulus that naturally and automatically triggers a response.
Unconditional Response (UR): the unlearned, naturally occurring response to the UCS.
Classical Conditioning• Next you find a neutral stimulus
(something that by itself elicits no response).
• You present the stimulus with the UCS a whole bunch of times.
Classical Conditioning
• After a while, the body begins to link together the neutral stimulus with the UCS.
• Acquisition
Classical Conditioning• We know learning
takes places when the previously neutral stimulus elicits a response.
• At this point the neutral stimulus is called the conditioned stimulus (CS) and the unconditional response becomes the conditioned response (CR).
Conditioned Response (CR): the learned response to a previously neutral stimulus.
Conditioned Stimulus (CS): an originally neutral stimulus (NS) that, after association with the UCS, comes to trigger a response.

Unconditioned Response (UCR)Salivation
Conditioned Stimulus (CS)Bell
Conditioned Response (CR)Salivation
* Hint: replace “conditioned” with “learned” to make it more intuitive.
Things to Remember:
• The responses (UR & CR) are always the same.
• The NS and the CS are always the same. The NS becomes the CS through learning.
A friend has learned to associate the sound of a dentist’s drill to a fearful reaction because of a painful experience
she had getting a root canal. In this example, what is the:
– UCS? Pain from the drill– UCR? Fear– CS? Sound of
the drill– CR? Fear
A BMW commercial has lots of pretty people in it. People who watch the commercial find the people pleasing
to look at. With repeated viewing, they begin to associate the car with the pleasant feeling.
• UCS? Pretty people
• UCR? Feeling good
• CS? Sight of BMW
• CR? Feeling good
