THREE BASIC TYPES OF LEARNING
• Classical Conditioning- response to a stimulus
• Operant Conditioning- rewards behavior
• Modeling- watching others

CLASSICAL CONDITIONINGCLASSICAL CONDITIONING
A Learning Proceedure that causes a subject to learn a response to a stimulus that normally does not cause that response.

CLASSICAL CONDITIONING
IVAN PAVLOV- scientist studying digestion using dogs as subjects…
Became one of the scientists of note studying
Behaviorism

Classical Conditioning Components
Neutral Stimulus (NS)- Has nothing to do with a response before conditioning
Unconditioned Stimulus (UCS)- Something that will lead to a predictable response
Unconditioned Response (UCR)- Something that occurs naturally
Tuning Fork/ Bell
Food
Salivation

Generalization:
Discrimination: only
Extinction: CR does not happen due to lack of UCS
Spontaneous Recovery: CR returns after Ucs returns for awhile
or = CR

OPERANT CONDITIONINGOPERANT CONDITIONING
Learning from consequences of behavior
•Stray dog getting fed in a neighborhood•Paying bills on time- good credit, don’t lose house
•Getting attention for misbehaving- individual doesn’t care what type of attention they get aslong as they get it

Classical- Stimulus is provided to conditionbehavior
Operant- Behavior results from rewardor punishment
Differences between Classical and Operant Conditioning

Psychologist famous for experiments inOPERANT Conditioning
![Page 34: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/34.jpg)
Skinner determined that rewards and punishmentsShape behavior
![Page 35: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/35.jpg)
An animal placed inside the box is rewarded with a small bit of food each time it makes the desired response, such as pressing a lever or pecking a key. A device outside the box records the animal's responses.

Journal Entry #4
• Describe a time in your life when you learned how to do something. Describe the process that you went through to learn. After you describe the learning event determine which type of learning it was: Classical Conditioning, Operant Conditioning, or a combination of the above.
![Page 37: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/37.jpg)
Reinforcement
• Important factor in operant conditioning is timing and frequency of reinforcement• Partial schedule- when positive reinforcement
occurs immediately but not every time• Skinner learned of the effectiveness of partial
reinforcement when the “Skinner Box” broke • it is generally a more stable and longer lasting
behavior
A stimulus or event that follows a behavior that eitherreinforces or discourages a behavior
![Page 38: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/38.jpg)
4 Schedules of Reinforcement
• Fixed Ratio-
• Variable Ratio-• Fixed Interval-.
• Variable-Interval-
![Page 39: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/39.jpg)
Two ways that stimuli can affect our behavior
1. Reinforcement
2. Punishment
![Page 40: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/40.jpg)
ReinforcementStimulus or event that follows a
response and increases the likelihood that the response will continue
2 types: Positive and Negative
![Page 41: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/41.jpg)
Positive Reinforcement:When something the subject wants is rewarded after the desired response.
Example: Receiving a day off after coming to work on time without missing for 9 weeks straight
(Removal)
![Page 42: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/42.jpg)
Negative Reinforcement:When a painful or unpleasant stimulus is removedIt follows and negates (takes away) something unpleasant
Example: After successfully completing 15 problems showing your work you get to finish the next 15 with awithout it.
(Removal)
![Page 43: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/43.jpg)
Two Results of Negative Reinforcement
• Escape Conditioning:Persons behavior causes an
unpleasant event to stop.
Child hates liver- Mom serves liver- Child gags and has fit- Mom removes liver
Child will react this way every time food is served it doesn’t like
• Avoidance ConditioningPersons behavior has the
affect of preventing an unpleasant situation from happening
Stretching the truth to avoid hurting someone’s feelings because you have seen them upset before
![Page 44: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/44.jpg)
Aversive Control
An unpleasant or (aversive) consequence that follows an undesirable behavior
![Page 45: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/45.jpg)

2. Punishment
Painful or unpleasant stimulus is applied.
Most obvious aversive control method
Punishers include but are not limited to:•Spanking•Yelling•Evil eye•Cold shoulder
![Page 47: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/47.jpg)
Disadvantages of Aversive Control
• Can produce rage, aggression and fear which can lead to other behavior problem- children who are abused grow up to be abusers…..also abusive to other children
• People will learn to avoid the person delivering the aversive stimuli- can cause relationship problems
![Page 48: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/48.jpg)
Punishment alone is not an effective way to teach…..
Without positive coaching and modeling of acceptablebehaviors the child may never learn the correct behavior.

Learning Complicated Skills
Shaping- process of reinforcement used to sculpt
behavior
reward each segment of behavior that is in the direction of the desired behavior
![Page 50: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/50.jpg)
Response Chains- Combining responses to perform a skill:Each response produces a signal for the next:
Hammering a nail:
1. Pick up hammer2. Pick up nail3. Position nail4. Hit nail
![Page 51: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/51.jpg)
Response Patternwhen you combine response chains: ex: Swimming- arm chain- kicking chain- breathing chain
Arm movementchain
Kickingchain
Breathing chain
Swimming

Factors that affect Learning
1. Feedback- results from tests or listening to yourself sing
2. Transfer- A skill you have already learned helpsor hinders you in learning a new one
Positive- helps Negative- hurts
3. Practice- Repetition of a task helps reinforce learningExample: playing a few measures over and over instead ofplaying the whole song
![Page 53: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/53.jpg)
4.Learned Laziness rewards come with little effort, person never learns to work- when it gets hard they don’t give effort necessary to learn

5. Learned HelplessnessNegative results no matter how hardlearner tries.
This condition results when repeated attempts to control a situation fail, resulting in the belief thesituation is uncontrollable
•Person gives up
•Can be a source of depression
![Page 55: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/55.jpg)
Social LearningThe process of learning from observingand imitating others in ones social environment
![Page 56: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/56.jpg)
Learning by reacting to others--------
1. Modeling- doing what you see others do i.e., clapping in church
2. Observational learning- Imitating (dancing)
3. Disinhibition- Watching others in a threatening activity without negative consequence might make it easier to try later
i.e, going off of the diving board for the first time
![Page 57: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/57.jpg)
Cognitive Learning:Learning that focuses on how information is obtained mentally…..
Cognitive map: a mental picture which results in
Latent Learning
![Page 58: Chapter 9 LEARNING: Principals and Applications Learning: a relevantly permanent change in behavior that results from experience.](https://reader037.fdocuments.us/reader037/viewer/2022110321/56649cee5503460f949bcbc7/html5/thumbnails/58.jpg)
Behavior ModificationApplication of learning principles to change peoples actions and feelings
1. Computer-Assisted Instruction2. Token Economies3. Self Control- self discipline- setting up personal rewards and punishments-• reading one more page- running 10 more yards, answering one more question• keeping track of behaviors (weight loss, smoking)
