Operant Conditioning
Reinforcement Schedules
How often to you give
the reinforcer?
• Every time or just
sometimes you see
the behavior?
Continuous v. Partial
Reinforcement
•
•
•
•
Continuous
Reinforce the behavior
EVERYTIME the behavior
is exhibited.
Usually done when the
subject is first learning
to make the association.
Acquisition comes really
fast.
But so does extinction.
Partial
• Reinforce the behavior
only SOME of the times
it is exhibited.
• Acquisition comes more
slowly.
• But is more resistant to
extinction.
• FOUR types of Partial
Reinforcement
schedules.
Ratio Schedules
Fixed Ratio
• Provides a
reinforcement after a
SET number of
responses.
Variable Ratio
• Provides a
reinforcement after a
RANDOM number of
responses.
• Very hard to get
acquisition but also very
resistant to extinction.
Fixed Ratio- She gets a manicure for every 5
pounds she loses.
Interval Schedules
Fixed Interval
Variable Interval
• Requires a SET amount
of time to elapse before
giving the
reinforcement.
• Requires a RANDOM
amount of time to elapse
before giving the
reinforcement.
• Very hard to get
acquisition but also very
resistant to extinction.
