B-5 Schedules of Reinforcement Flashcards
Continuous Schedules of Reinforcement
A reinforcer is delivered after each instance of target or desired behavior
Ex: Gets praise for each question answered correctly
Intermittent Schedules of Reinforcement
Contingency in which a reinforcer is not delivered every time a target response is given; it is given every so often.
4 types of intermittent schedules:
- Fixed Ratio (FR)
- Variable Ratio (VR)
- Fixed Interval (FI)
- Variable Interval (VI)
Fixed Ratio
Schedule of reinforcement requiring a fixed number of correct responses for reinforcement
Ex: FR4- reinforcement follows every 4 correct response
Variable Ratio
Reinforcer is given after a non-specific but average number of correct responses
Ex: VR7- About every 7 times the dog sits when told, he gets a treat
Fixed Interval
Reinforcer is given after a correct response immediately after a specified period of time
Ex: Every 10min child practices piano, he is given a token to add 15min to bedtime (FI-10min)
Variable Interval
Reinforcer is given after a correct response immediately after a non-specific period of time (The average interval must be defined)
Ex: For about every 15min sister does yard work, she is offered a glass of lemonade (VI-15min)
Post Reinforcement Pause
An absence in responding for a period of time following a reinforcement
An effect commonly produced by FR and FI schedules of reinforcement
Ratio Strain
Decrease in responding when the requirement for reinforcement is too high
Occurs generally in FR schedules
Limited Hold
The reinforcer is available only for a set time
If learner doesn’t attempt to access reinforcer during the Limited Hold, they will lose it for that opportunity.
Scallop Effect
Refers to the minimal post reinforcement pause as learner resumes earning reinforcers
Generally increased responding rate when reinforcement time is approaching
Occurs in FR and FI schedules of reinforcement
Thicker Schedule of Reinforcement
Requires fewer responses and has more reinforcement opportunities
Thinner Schedule of Reinforcement
Requires more responses and has less reinforcement opportunities
Compound Schedules of Reinforcement
Includes 2 or more schedules of reinforcement used for a target behavior
Types of compound schedules:
- Alternative Schedule
- Conjunctive Schedule
- Concurrent Schedule
- Multiple Schedule
- Mixed Schedule
- Chained Schedule
- Tandem Schedule
Alternative Schedule (ALT)
Requires the learner to meet EITHER a determined ratio schedule OR interval schedule in order to access reinforcer
Ex: break given after assembling 20 bottles or after working for 1 hour (ALT FR-20 FI-1 hour)
Conjunctive Schedule (CONJ)
Requires learner to meet criteria of BOTH ratio and interval schedule to access reinforcer
Ex: Coach gives water break when athlete does at least 150 jumping jacks and spends at least 2min doing jumping jacks
