Flashcards in Schedules of reinforcement Deck (20):
Provides reinforcement for every occurrence of the behaviour. Used for skill acquisition
Progresses to naturally occurring reinforcement. Used to strengthen established behaviours.
Require a number of responses before a response produces reinforcement.
Specific amount of time elapses and the response following this time produces reinforcement.
Fixed Ratio 4 (FR 4)
Reinforcement is delivered after every 4th correct response.
Fixed Interval 2 (FI 2)
Reinforcement is delivered for the first response after the 2 minutes have elapsed.
Variable Ratio 4 (VR 4)
Reinforcement is delivered an average of every 4th correct response.
Variable Interval 2 (VI 2)
Reinforcement is delivered for the first response after an average of 2 minutes has elapsed.
Abrupt increases in ratio requirements when moving from dense to thinner reinforcement schedules
Increasing response ratio or duration of time interval
Reinforcement remains available for a finite time following the elapse of the FI or VI interval
The rate of responding typically is proportional to the rate of reinforcement received from each choice alternative.
The Matching Law
Two or more contingencies of reinforcement operate independently and simultaneously for two or more behaviours.
Two or more basic schedules of reinforcement alternating randomly, and a discriminative stimulus is correlated with each basic schedule.
Basic schedules occur in a specific order and have discriminative stimuli for each.
Identical to multiple but has no discriminative stimuli correlated with the schedules.
Similar to chained but does not use a discriminative stimulus.
Behavioural principles observed with nonhumans will apply to humans
Human behaviour may involve additional principles from those observations with nonhumans
