Learning Operant Conditioning
Operant vs. Classical Conditioning
✤ Both associative types of learning & involve acquisition, extinction, spontaneous recovery, generalization & discrimination
✤ Classical: an organism associates different stimuli that it does not control & responds AUTOMATICALLY
✤ Operant: an organism associates its behaviors (those that act on the environment to produce rewarding or punishing stimuli) with their CONSEQUENCES
Operant Conditioning
✤ Question #1:
✤ Do you want this particular behavior to CONTINUE?
✤ Yes = you will REINFORCE the behavior.
✤ No = you will PUNISH the behavior.
Operant Conditioning
✤ Question #2:
✤ Are you adding something to the environment or subtracting something from the environment?
✤ Addition = Positive Reinforcement (appetitive) & Positive Punishment (aversive)
✤ Subtraction = Negative Reinforcement (aversive) & Negative Punishment (appetitive)
Operant Conditioning
Appetitive :) Appetitive :) (Something desired) (Something desired)
Aversive :( Aversive :( (Something not desired)(Something not desired)
Addition to
environ.
Positive Reinforcement(Businessman meets
quota & receives bonus)
Positive Punishment
(Little kid runs into the street & gets
spanked)
Subtraction from environ.
Negative Punishment(Time-out from something fun)
Negative Reinforcement(Tylenol for a
headache)

Continuous vs. Partial (intermittent) Reinforcement
✤ Continuous: learning occurs rapidly, this reinforcement is preferable until a behavior is mastered; however, extinction also happens more rapidly
✤ Intermittent: learning is slower, but it produces greater resistance to extinction
Reinforcement Schedules
✤ Fixed-Ratio Schedule: dependent on the behavior itself- a certain number of behaviors are necessary before reinforcement occurs (punch cards)
✤ Variable-Ratio Schedule: reinforcement after an unpredictable # of responses (slot machines)
✤ Fixed-Interval Schedule: involves a time element- time must pass before reinforcement will occur (expecting a delivery)
✤ Variable-Interval Schedule: reinforces the first response after varying time intervals (checking email)
