Instrumental Conditioning Flashcards
(28 cards)
Instrumental conditioning
Learning the contingency between behaviours and their consequences
Thorndike
Put a cat in a puzzle box with a dish of food outside and a lever to open the door
Stamping in (satisfying effect)
Behaviours with positive consequences get stamped in
Stamped out (unsatisfying effect)
Behaviours with negative consequences get stamped out
Reward training
Presentation of a positive reinforcer
Punishment training
Presentation of a negative reinforcer
Omission training
Removal of a positive reinforcer
Escape training
Removal of a negative reinforcer
Autoshaping
Learning without direct guidance, rewards behaviour that may occur spontaneously
Successive approximation
Complex behaviour can be broken down into smaller steps which gradually build up to the full response
SD
Signals when a contingency is valid
S delta
Signals when the contingent relationship is not valid
Fixed ratio
Pause and run pattern, ex getting a reward every three times you clean your room
Fixed interval
A fixed amount of time, scallop pattern
Variable ratio
Straight line, reinforcement is given some random number of responses
Variable interval
Reinforcement delivered after random amount of time
Primary reinforcer
Satisfies biological need
Secondary reinforcer
Established through classical conditioning, ex money
Observational learning
Just after birth we are able to learn from observing others behaviours
Aversive stimulus
Something unpleasant, negative reinforcer
Delay in gratification
Ability to delay rewards
Chaining
Response is reinforced with the opportunity to perform the next response (similar to higher order conditioning)
Contrast effects
Changes in value of reward led to shifts in response rate
Negative contrast
Switch from a high reward to a low reward now respond at a slower rate
