Shedules of Reinforcement Flashcards
Schedules of reinforcement
The rule describing the delivery of reinforcers for a behaviour
Schedule effects
Distinctive rate and patterns of behaviour associated with a particular reinforcement schedule
Continuous reinforcement
Reinforcement every time
Fixed ratio of reinforcement (FR)
For every fixed number of times, a behaviour occurs a reinforcer is given.
Intermittent schedule
When reinforcement happens on some occasions but not others
FR 3 schedule
Reinforcement every 3 times a behaviour occurs
Post-reinforcement pauses
Pre-ratio pauses
Between-ratio pauses
A pause in responding following reinforcement; associated primarily with FR schedules
Run rate
The rate at which behaviour occurs
Variable ratio or VR schedule
The average of reinforcement given might be 5 (VR 5) which means it might be given after 3 behaviours, then after 2, then after 7.
Slot machines operate on VR schedules
Fixed interval schedules (FI)
Reinforcement is dependent on the behaviour occurring after a given period since the last reinforcer was given
Variable interval schedules
Reinforcement is given on average. Might be after 2 seconds, after 8 seconds or after 4 seconds since last reinforcer was given.
Extinction
To reduce a behaviour by no longer giving reinforcement
Extinction burst
When the reinforcer stops and the subject starts doing the behaviour more often to try and get the reinforcer back.
Resurgence
When a reinforcement stops for behaviour X the subject might take up behaviour G, which is has previously been given reinforcements for.
Fixed duration schedule
The behaviour needs to be present for a fixed duration of time before reinforcement is given.
