Shedules of Reinforcement Flashcards
(33 cards)
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.
If you sit still for 30 minutes you get an ice cream
Variable duration schedule
The average of time before a reinforcement is given.
Noncontingent reinforcement schedules
Reinforcers are given on either a fixed time or variable time schedule regardless of behaviour.
Progressive schedules
The requirements progressively increase systematically
Progressive ratio schedule
Reinforcement is given after one push, then after 2 pushes, then after 6, then 8 and so forth.
Breaking point
When the progressive ratio schedule requires too big of a gap between reinforcers that behaviour stops.
Stretching the ratio
In progressive ratio scheduling, the researcher slowly increases the number of behaviours needed before a reinforcer is given.
Multiple schedules
There are multiple schedules used and there is some kind of indicator of what schedule is occurring at all times.
Mixed schedule
There are multiple schedules used but there is no indicator of what schedule is occurring.
Chain schedule
A compound reinforcement schedule that consists of a series of simple schedules, each of which is associated with a particular stimulus, with reinforcement delivered only on completion of the last schedule in the series.
