Learning
What does it mean to learn?
Provide a definition in your notebook.
•
A relatively permanent change in behavior
or the potential to make a response that
occurs as a result of experience.
•
Give an example from today of something
you have learned….
What are the three types
of learning?
•
Classical Conditioning: Respondent
•
Operant Conditioning: Instrumental
•
Observational Learning: Modeling
What is your response to the
following stimuli?
•
You have not eaten for days and you are
presented with your favorite food
•
You are in a hurry and stuck in traffic with
your mom.
•
You are watching tv and Dr. Phil comes on.
•
You hear a Brittany Spears song on the
radio.
•
You are full but you see an entire bag of
BBQ chips.
Why are Pavlov’s dogs so famous?
Classical Conditioning
•
Ivan Pavlov 1849-1936
• Nobel Prize in 1904 for studies of
digestion!
•
•
But really, what he did was test Classical
Conditioning!
CC: Learning that occurs when two stimuli
are paired and become associated with
each other.

Basic Elements of Classical
Conditioning
•
Stimulus: trigger or event
•
Neutral Stimulus (NS) - Stimulus that does not elicit
a particular response. (Who cares)
•
Unconditioned Stimulus (UCS) - Event that
automatically produces a response without any
previous training. (Causes an immediate reaction)
•
Unconditioned Response (UCR) - Reaction that is
automatically produced when an unconditioned
stimulus is presented. (Reflex)
Classical Conditioning
Continued
•
Conditioned Stimulus (CS) - Neutral
Stimulus that acquires the ability to elicit a
conditioned response after being paired with
an UCS. (Mistaken identity!)
•
Conditioned Response (CR) - Response
elicited by a conditioned stimulus that has
been paired with an unconditioned stimulus;
is similar to the unconditioned response.
(False response)
Pavlov’s Dog vs.
Little Albert
•
Pavlov’s Dog: Ivan Pavlov
•
Little Albert: John B. Watson
•
NS –
•
NS- bunny or rat
•
UCS – Meat Powder
•
UCS-
•
UCR –
•
UCR
•
CS - Metronome
•
CS
•
CR -
•
CR
Are these studies ethical?
Other vocab terms
•
Acquisition: training stage of when is a response is learned
•
Extinction: elimination of response
•
Spontaneous Recovery: response comes back after elimination
•
Generalization: response spreads to other things
•
Discrimination: response is only directed at CS
•
Taste Aversion: when food is a CS for a bad CR
•
(BBQ Chips)
