tutorial and computer practice exercise (this is not perfect for our class
but will give you some practice exercises)
Simple schedules of Reinforcement
- Fixed ratio (FR) schedules deliver
reinforcement after every nth response
- Example: FR2 = every second response is
reinforced
- Lab example: FR5 = rat reinforced with
food after each 5 bar-presses in a
Skinner box.
- Real-world example: FR10 = Used car
dealer gets a $1000 bonus for each 10 cars sold on
the lot.
- Continuous ratio (CRF) schedules are a
special form of a fixed ratio. In a continuous ratio
schedule, reinforcement follows each and every response.
- Lab example: each time a rat presses a
bar it gets a pellet of food
- Real world example: each time a dog
defecates outside its owner gives it a treat
- Fixed interval (FI) schedules deliver
reinforcement for the first response after a fixed
length of time since the last reinforcement, while
premature responses are not reinforced.
- Example: FI1" = reinforcement provided
for the first response after 1 second
- Lab example: FI15" = rat is reinforced
for the first bar press after 15 seconds passes
since the last reinforcement
- Real world example: FI24 hour = calling a
radio station is reinforced with a chance to win a
prize, but the person can only sign up once per day
- Variable ratio (VR) schedules deliver
reinforcement after a random number of responses (based
upon a predetermined average)
- Example: VR3 = on average, every third
response is reinforced
- Lab example: VR10 = on average, a rat is
reinforced for each 10 bar presses
- Real world example: VR37 = a
roulette player betting on specific numbers will
win on average one every 37 tries (on a U.S.
roulette wheel, this would be VR38)
- Variable interval (VI) schedules deliver
reinforcement for the first response after a random
average length of time passes since the last
reinforcement
- Example: VI3" = reinforcement is provided
for the first response after an average of 3 seconds
since the last reinforcement.
- Lab example: VI10" = a rat is reinforced
for the first bar press after an average of 10
seconds passes since the last reinforcement
- Real world example: a
predator can expect to come across a prey on a
variable interval schedule
