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)

Appetitive :) Appetitive :) (Something desired) (Something desired)

Aversive :( Aversive :( (Something not desired)(Something not desired)

Addition to

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)
