Operant Conditioning

Operant conditioning 
- a type of learning in which behavior is strengthened if followed by reinforcement or diminished if followed by punishment 

Classical vs operant 
-they both use the 5 things "ADSGE"
-classical is automatic (respondent behavior). Dogs automatically salivate over meat, then bell no thinking involved 
-operant involves behavior where one can influence their environment 
With behavior which has consequences 

Edward thorndike
- law of effect rewarded behavior is likely to recur 

BF skinner 

Shaping 
-a procedures in operant conditioning in which reinforcers guide behaviors closer and closer towards a goal

Reinforcers 
- ant events that strengthen the behavior it follows 

2 types of reinforcement 
- positive and negative 

Positive reinforcement 
- strengthens a response by presenting a stimulus after a response 

Negative reinforcement 
-strengthen a response by reducing or removing an aversive stimulus

Primary reinforcer
- an innately reinforcing stimulus 

Conditioned reinforcer (secondary )
-a stimulus that gains it reinforcing power through its association with a primary reinforcers 

Continuous reinforcement
-reinforcing the desired response every time it occurs 

Partial reinforcements 
-reinforcing a response only part of the time 
- the acquisition process is slower
-greater resistance to extinction 

Fixed ratio schedule 
-a schedule that reinforces a responses only after a specified # of responses 

Variable-ratio schedule 
- a schedule reinforcement that reinforces a response 

Fixed interval schedule 
-a schedule reinforcement that reinforces a response only after a specific time has elapsed

Variable-interval schedule 
- a schedule of reinforcement that reinforces a response at unpredictable times intervals 

Punishment 
-meant to decrease a behavior 

Positive 
-addition of something unpleasant 

Negative
- removal of something pleasant 

Punishment works best when it is immediately done after behavior and if it is harsh 

Token economy 
- every time a desired behavior is preformed, a token is given 
- they can trade tokens in for a variety o prizes (reinforcers)
-used in homes, prison, mental institution, and school

Observation learning 
-Albert bAndura and his bobo doll
- we learn through modeling behavior from others
- observation learning + operant conditioning = social learning g theory 

Latent learning 
-Edward Toleman 
-sometimes learning is not immediately evident 

Insight learning 
- Wolfgang Koehler and his chimpanzees 
- aha moments . Learning through experience
