Learning Psychology
Bell Activity 3/22/2013
Learning Targets: At the end of class you will be able to-
-Define Classical Conditioning
-Define and Identify the Unconditioned Stimulus, Unconditioned Response, Conditioned Stimulus, and Conditioned Response
-Apply these terms to different situations
1.)Explain, in a step-by-step process, how to teach a dog to shake hands.
2.) Work on Vocabulary
Reminder: TODAY is the last day to make up tests for units 1-4. The unit 5 Test must be made-up by next Thursday 3/28)
What is Learning?
Learning is a relatively permanent change in a behavior tendency that results from experience.
Classical Conditioning
Learning procedure in which associations are made between a neutral stimulus and an unconditioned stimulus.
(Don’t worry, we’ll explain all of this in more detail a little later!)
Ex: Pavlov’s Doghttp://www.youtube.com/watch?v=hhqumfpxuzI
Classical Conditioning
Neutral Stimulus (NS): Stimulus that does not initially elicit any part of an unconditioned response.
In Pavlov’s experiment, the bell is the neutral stimulus. Before the experiment, the bell had nothing to do with the dog salivating
Classical Conditioning
Unconditioned Stimulus (US): An event that elicits a certain predictable response without previous training
Food was the US in the experiment. Food caused to dog to salivate without any training
Classical Conditioning
Unconditioned Response (UR): An organism’s natural reaction to a stimulus
The salivation was the UR in the experiment; This is an automatic reflex the dog has when he smells food
Classical Conditioning
Conditioned Stimulus: A once-neutral event that elicits a response after a period of training in which it has been paired with an unconditioned stimulus.
Ex: The bell normally does not mean anything to the dog. Now, the dog has
been taught, or conditioned, to associate the sound with food.
Classical Conditioning
Conditioned Response: The learned action to a conditioned stimulus
This is the salivation that occurs in response to the bell; There was
no prior relationship.
This is a learned
response.
Classical Conditioning: General Principles
Acquisition of a conditioned response occurs gradually
Connection strengthens over time
Timing also very important; Most effective when the CS was introduced just before the US
Classical Conditioning: General Principles
Generalization: Animals responds to a stimulus that is similar to the original CS.
Ex: Dog responded to circle as well as oval; Develop fear of the sound of a dentist’s drill=fear of the sound of all drills
Classical Conditioning: General Principles
Discrimination: The ability to respond differently to different stimuli
Ex: Taught dog to respond differently to the oval and the circle.
Classical Conditioning: General principles
Extinction: Gradual disappearance of a conditioned response.
Happens when a conditioned stimulus is presented without the unconditioned stimulus
Classical Conditioning and Human BehaviorConditioning helps humans and animals
predict what is going to happen next.Case of Little Albert

linking food to a bad experienceCan you think of other ways that we use
classical conditioning in everyday life?
Bell Activity 3/28/2013
Learning Targets: At the end of class you will be able to
-Apply knowledge of classical conditioning to examples
-Define and describe operant conditioning
-Create experiments to illustrate classical and operant conditioning
1.) What is classical conditioning?
2.) In Pavlov’s experiment, what was the conditioned stimulus?
3.) Do you think schools should use capital punishment (spanking) as a means to deter bad behavior? Why or why not?
The unit 5 Test must be made-up by Today!!!
All projects must be turned in by Today!!!!
Classical Conditioning
A Quick Review:

Classical Conditioning..as explained by Frasier Crane
Watch the following clip and list the US, UR, CS and the CR

Classical Conditioning Experiment
You can either work alone or with A partner
Create your own classical conditioning experiment
Identify the US, UR,CS and CR
Classical Conditioning Summary
Write a paragraph summarizing classical conditioning in your own words. Be sure to include how it works as well as terminology (US, UR, CS,CR).

After viewing the clip, describe how you think operant conditioning works
Operant Conditioning
Learning in which a certain action is reinforced or punished, resulting in corresponding increases or decreases in occurrence
Operant Conditioning
B.F. Skinner psychologist most closely associated with operant conditioning
Believed a person’s behavior is a result of history of rewards and punishments
“Skinner Boxes”
Operant Conditioning
Reinforcement: Stimulus or event that increases the likelihood that a behavior will be repeated
Give a positive reinforcer when correct behavior is exhibited.
A negative reinforcer is when something unpleasant Is taken away.
Operant Conditioning: Schedules of Reinforcement
More effective when positive reinforcement occurs intermittingly.
Fixed-ratio schedule: Reinforcement depends on a specified quantity of responses
Variable-Ratio: Unpredictable number of responses required (slot machines).
Operant Conditioning: Schedules of Reinforcement
Fixed-Interval: A specific amount of time must elapse before a response will illicit a reinforcement
Variable-Interval: The time which reinforcement is given changes
Operant Conditioning
Shaping: Desired behavior is molded by first rewarding any action that is similar to the desired behavior and requiring ever-closer approximations of the desired behavior
Chaining: Learned reactions that follow one another in sequence. Each reaction leads to the next. (Learning to swim)
Operant Conditioning: Aversive Control
Influencing behavior by using unpleasant or unwanted stimuli
2 Types: Negative Reinforcement and Punishers
Operant Conditioning: Aversive Control
Negative Reinforcement: Removal of painful or unwanted stimulus
Operant Conditioning: Negative ReinforcementA painful or unpleasant
stimulus is removed in order to increase the frequency of behavior.
Escape Conditioning: a person’s behavior causes an unpleasant event to end
Avoidance Conditioning: behavior that prevents an unpleasant situation from happening
Ex: A child whines and gags while being forced to eat meat loaf because she doesn’t like it and the parent removes the meatloaf (escape)
If the child whines as soon as it comes out of the oven and is not served meatloaf (avoidance)
Operant Conditioning: Punishment
An unpleasant consequence that occurs to decrease the frequency of a behavior.
Opposite of negative reinforcement
Ex: Reprimanding a dog that jumps on you.
Operant Conditioning: Disadvantages to Punishment
Can produce unwanted side effects such as rage, aggression and fear
People tend to avoid situations where they experience punishments (stay away from teachers who use aversive punishments)
Punishment does not teach appropriate and acceptable behaviors
