SAFMEDs Chapter 9: Classical and Operant Conditioning Flashcards
Shaping
- shaping one’s behavior using rewards in order to achieve desired behavior
Successive approximations
- steps towards a target goal.
- rewarded in order to reinforce the behavior
Chaining
-linking learned behaviors to create more complex behavior
Ratio schedules
- behavior dependent
- can be fixed or variable
Fixed ratio reinforcement schedule
- a behavior is reinforced after “n” behaviors
- buy five frozen yogurts get the sixth one free
Variable ratio reinforcement schedule
- behavior is reinforced after a variavle number of behaviors
- most powerful reinforcement schedule
- Gambling
Learning
-relatively permanent changes in behavior resulting from experience or practice
Behaviorists
- learning theorists
- adherent to the behavioral perspective
- John Locke
- John Watson
John Locke
- father of liberalism
- tabula rasa: blank slate
- the individual we become is the result of experience
Environmental determinism
- our environment shapes every aspect of who we were, are and will become
- we can change who people are by manipulating the circumstances in which they develop
John Watson
- founded behaviorism
- give me a dozen healthy infants and my own specified world to bring them up in and Ill guarantee to take any one at random and train him to be any kind of specialist I select
Ivan Pavlov
- classical conditioning
- Pavlov’s dogs
- provided experimental support for the views of behaviorists
Classical Conditioning
- links a neutral stimulus to another stimulus that elicits a natural, involuntary response
- Pavlov’s dogs
Neutral stimulus
- a stimulus that evokes no special response except to call attention to it
- Pavlov’s bell
Associative learning
- learning by associating two stimuli
- ideas and experiences are linked and therefore reinforce each other
Stimulus response learning
- behavior manifests as a result of the interplay between stimulus and response
- behavior can be learned or modified through a stimulus and response
Acquisition
-the formation of a learned association
Unconditioned Stimulus- US or UCS
- any stimulus that elicits an automatic/involuntary response in an organism
- food makes dogs salivate, food is UCS
Unconditioned Response- UR or UCR
- a reflex or autonomic response
- salivation
Conditioned stimulus- CS
- neutral stimulus paired with the US
- pairing the bell with food
