Ch. 6 - Intro to Operant Conditioning Flashcards
what is the difference between classical and operant conditioning?
classical conditioning focuses on involuntary behaviours while operant conditioning focuses on voluntary behaviours
operant conditioning
- a type of learning in which the future frequency (or probability) of a behaviour is affected by its consequences
- response operates on the environment to produce a consequence
- the effects of the consequences of a behaviour
- learning associations between behaviours and the consequences of them
operant behaviours
- behaviours that are influenced by their consequences
- consequences affect future frequency
- emitted by the organism rather than elicited by stimuli
adaptive behaviours
- those made in responses to changes in the environment
Thorndike’s law of effect
- behaviours leading to satisfying state of affairs are strengthened or “stamped in” while behaviours leading to an unsatisfying or annoying state of affairs are weakened, or “stamped out”
why is Skinner’s box a “free operant” way of investigating behaviour
- allows animal to respond freely at any time
- doesn’t require researcher to keep putting them back into a maze (ex.)
how can operant conditioning be adaptive
- adaptive behaviours lead to favourable outcomes and become more frequent
- maladaptive behaviours that don’t lead to favourable outcomes become less frequent
what behavioural patterns happen after many trials in the puzzle box?
- it may seem accidental at first but after a while associations between stimuli become stronger and the behaviours become purposeful
SR
an event is a reinforcer if:
- it follows a behaviour
- the future freuquency (strength) of that behaviour increases
what are the 3 components to operant conditioning?
- a response that produces a certain consequence
- the consequence that serves to either increase or decrease the frequency of the response that preceded it
- a discriminative stimulus that precedes the response and signals that a certain consequence is now available
SP
an event is a punisher if:
- it follows a behaviour
- the future frequency (strength) of that behaviour decreases
extinction
- the weakening of a behaviour through the nonreinforcement of a previously reinforced behaviour
SD
discriminative stimulus
- a stimulus in the presence of which responses are reinforced and in the absence of which they are not reinforced
- i.e. context, situation/environment
- doesn’t automatically elicit a behavioural response like a CS or US, just increases the probability of the behaviour occurring
Three-term contingency
- a rule that specifies when reinforcement will occur
- discriminative stimulus, response, reinforcement
SDP
Discriminative stimulus for punishment
- a stimulus that signals that a response will be punished
- ex. cadbury behaving well when she sees the haulty
Discriminative stimulus for extinction (Sdelta)
- stimulus that signals the absence of reinforcement
- ex. tone > lever press > food
buzzer > lever press > no food - in this case the buzzer is the discriminative stimulus for extinction because it signals that pressing the lever will not result in food
What are the 4 contingencies
- positive punishment
- positive reinforcement
- negative punishment
- negative reinforcement
Positive reinforcement
- presentation of a stimulus following a response
- usually considered pleasant or rewarding
- leads to an increase in the future strength (frequency) of that response
Negative reinforcement
- removal of a stimulus following a response
- usually considered unpleasant or aversive
- leads to an increase in the future strength (frequency) of that response
- take away something they don’t like so they’ll want to do it more in the future (help them out)
negative
- removal of a stimulus
positive
- presentation/addition of a stimulus
Positive punishment
- presentation of a stimulus following a response
- typically considered unpleasant or aversive
- decreases future strength (frequency) of that response
- what we typically consider “normal punishment”
punishment
- stimulus that is added or taken away is typically considered undesirable or aversive
reinforcement
- stimulus that is added or taken away is typically considered desirable and pleasant
