Classical Conditioning
Module 19
Learning Definition- relative permanent change in behavior caused by experience
Classical Conditioning- a type of learning where a stimulus gains the power to cause a response
Stimulus(anything in the environment that one can respond to) vs. Response- (any behavior or action)
Unconditioned Stimulus- stimulus that triggers a response reflexively
Unconditioned Response- automatic response to the UCS
Conditioned Stimulus- previously neutral stimulus that, through learning, gains the power to cause a response
Conditioned Response- response to the CS, it is the same as the UCR
Acquisition- process of developing a learned response/when the CS is paired with the UCS/something neutral becomes conditioned to cause a response
Extinction- the CS loses its power to trigger a CR/repeatedly present the CS alone
Spontaneous Recovery-return of an extinguished classically conditioned response after a rest period/recovered response is weaker/easier to extinguish again
Ivan Pavlov- russian physiologist/studying digestion
Pavlov’s Dogs
Generalization- an organism produces the same response to two similar stimuli
Discrimination- an organism produces different response to two stimuli/examples types of candy/being stung by a buzzing insect
John Watson- founder of behaviorism/criticized psychoanalysis view/behavior based on stimulus in environment, not thoughts in mind
Little Albert- phobias come from classical conditioning/fear generalized to other white animals
Taste Aversion- biologically predisposed to develop an aversion to the taste of food we ate before getting sick/evolution protection from poisonous food
Classical Conditioning & Advertising- the brand starts out as being neutral, they want you to learn to associate it with something from the advertisement
Module 20
Operant Conditioning- the frequency of a behavior depends on the consequence that follows that behavior
The Law of Effect- Edward Thorndike/behavior with favorable consequences will occur more frequently/behavior followed by less favorable consequences will occur less frequently
Reinforcement Positive- Behavior is followed by a desirable event or state/$ for grades
Negative Reinforcement- behavior ends an undesirable event or state/not having to do a chore because you got an A
Punishment Positive- Behavior followed by an undesirable event-toddler burned by a hot stove
Negative Punishment- Behavior ends a desirable state or event-girl who loses phone fighting with sister
Immediate vs Delayed Reinforcement- immediate is more effective than delayed/with age we learn value of delayed reinforcement
Primary Reinforcement- something naturally rewarding/food/warmth/water
Secondary Reinforcement- something you have learned is rewarding because it has been paired with primary reinforcement(money/grades)
Shaping- a way to establish new behaviors/reinforce behaviors that are increasingly similar to the one you want to occur
Extinction- loss of a learned response when reinforcement no longer follows it/helpful in changing ineffective behavior
Continuous Reinforcement- reward follows every correct response-most useful when teaching new behaviors/easy to extinguish
Partial Reinforcement- reward follows only some correct responses/lottery tickets/harder to extinguish
Fixed Partial Interval Reinforcement- rewards only the first correct response after some defined period of time/weekly quiz every Friday/
Variable Partial Interval Reinforcement- rewards the first correct response after an unpredictable amount of time/pop quizzes/students must alw study
Fixed Ratio Partial Reinforcement - reward only after a certain number of correct responses- 1 reinforcement for ever correct 20 responses
Variable Ratio- Partial- rewards an unpredictable number of correct responses/highest resistance to extinction/lottery tickets, slot machines
Observational Learning- Albert Bandura
Social Learning Theory- learning without direct experience, by watching and imitating others
