Ch. 6.1 - Operant Conditioning Flashcards
Operant conditioning
Type of learning in which behaviour is determined by consequences
Edward Thorndike (2)
- puzzle boxes with cats
- Law of effect: responses followed by satisfaction will occur again; those not followed satisfaction will become less likely
B. F. Skinner (2)
- coined ‘operant conditioning’
- used operant boxes (Skinner boxes)
Reinforcement
Process in which an event or stimulus (reinforcer) that follows a response increases the likelihood of that response occurring again
Punishment
Process in which an event or stimulus (punisher) decreases the future probability of it occurring again
Primary reinforcer
Consist of reinforcing stimuli that satisfy basic motivational needs (food)
Secondary reinforcer
Consist of reinforcing stimuli that acquire their value through learning (money)
Avoidance learning
Removing the possibility of a stimulus occurring
Escape learning
Occurs if a response removes a stimulus that’s already present
Effectiveness of punishment depends on (6)
- being understood
- severity
- initial punishment level
- contiguity
- consistency
- showing appropriate behaviours
As with classical conditioning, operant conditioning is also characterized by:
Discrimination, generalization, and extinction processes
Discriminative stimulus
Cue/event that indicated a response, that if made, will be reinforced
Delayed reinforcement
Reduces strength of stimulus-response pairing
Shaping (2)
- procedure in which a specific operant response is created by reinforcing successive approximations of that response
- step-by-step (cat toilet trained)
Applied behaviour analysis (ABA) (2)
- used with development conditions (autism)
- used to shape desirable behaviours
Schedules of reinforcement
Rules that determine when reinforcement is available
Continuous reinforcement (2)
- occurs when every response made results in reinforcement
- vending machines
Partial (intermittent) reinforcement
When only a certain number of responses are rewarded, or a certain amount of time must pass before reinforcement is available
Types of partial reinforcement (2)
- fixed vs variable schedules
- ratio vs interval schedules
Fixed RATIO schedule (2)
- reinforcement is delivered after a specific number of responses have been completed
- McCafe punchcard
Fixed INTERVAL schedule (2)
- reinforces the first response occurring after a set amount of time passes
- wait few min to get more stuff at PokeStop
Variable INTERVAL schedule (2)
- the first response is reinforced following a variable amount of times
- shooting star?? Boss checking on you
Variable RATIO schedule (2)
- the number of responses required to receive reinforcement varies according to an average
- gambling
Partial reinforcement effect (2)
- organisms conditioned under partial reinforcement resist extinction longer than those under continuous reinforcement
- problem gambling
Superstitions and reinforcement (4)
- superstations cab form when it’s not clear what behaviour led to the reward
- B. F. Skinner generated ‘superstitious’ behaviours in pigeons
- confirmation bias
- superstitions can have positive effects on controllable behaviour
