OBJECTIVE 8
WHAT IS OPERANT CONDITIONING & HOW IS IT DIFFERENT FROM
CLASSICAL CONDITIONING
CLASSICAL
CONDITIONING
behavior that occurs as an automatic response to some stimulus (no control)
Associate own actions with consequences
SKINNER’S EXPERIMENTS
Edward Thorndike’s Law of Effect
1874-1949
Rewarded behavior is likely to recur
Puzzle box
B.F. Skinner (1904-1990)
behavior control
Teach pigeons unpigeonlike behavior
SKINNER’S EXPERIMENTS
SKINNER’S EXPERIMENTS
SHAPING BEHAVIOR
Shaping
reinforcers guide successive approximations
Discriminative stimulus
in operant conditioning, a stimulus that elicits a response after association with reinforcement (in contrast to related stimuli not associated with reinforcement).
Teach pigeon to peck after seeing human face but not other images, pigeon learns to recognize faces…faces= discriminative stimulus
OBJECTIVE 9
WHAT ARE THE BASIC TYPES OF REINFORCERS?
Reinforcer
Anything that strengthens the behavior it follows
Positive reinforcement – adds a positive
Negative reinforcement punishment
Not punishment
– removes a negative
Removes a punishing event
3. Do people look forward to negative reinforcement: yes / no
NEGATIVE REINFORCEMENT
Taking aspirin to relieve headache
Putting mittens on because it is cold
Giving in to a whining child
Fanning oneself to escape the heat
Leaving a movie theater if the movie is bad
Smoking in order to relieve anxiety
Feigning stomachache to avoid school
Putting up umbrellas to escape the rain
SKINNER’S EXPERIMENTS
TYPES OF REINFORCERS
Primary reinforcer
Satisfies a biological need
Conditioned reinforcer
Gains its reinforcing power through its association w/ the primary reinforcer
Secondary Reinforcer
Immediate vs Delayed Reinforcers
immediate best in animals
Humans respond to delayed
Social competent & highachieving
OBJECTIVE 10:
WHAT ARE THE TWO REINFORCEMENT SCHEDULES & HOW
DO THEY EFFECT BEHAVIOR?
1. Continuous Reinforcment
Learning occurs rapidly, but…
Extinction occurs rapidly
2. Partial (intermittent) Reinforcment
Slower to learn but more resistant to extinction
4 types of partial schedules
Skinner’s Experiments
Reinforcement Schedules
Interval (2) Ratio (2)
dependent on the behavior itself; a certain number of responses are needed before reinforcement will occur
involves a TIME element; time must pass before reinforcement will occur
FIXED –INTERVAL
FIXED –RATIO
reinforce behavior after set # of responses
VARIABLE-RATIO
reinforce 1 st response after set time…produces stop-start behavior (more as reward draws near)
reinforce behavior after unpredictable # of responses…slot machine
VARIABLE-INTERVAL
reinforce 1 st response after varying time intervals

OBJECTIVE 11:
HOW DOES PUNISHMENT EFFECT
BEAHVIOR?
Punishment
Positive punishment
Negative punishment
Negative Reinforcement encourages behavior.
When something unpleasant ceases, the behavior that caused it to stop is reinforced
Skinner’s Experiments
Punishment

Skinner’s Experiments
Punishment
SENSITIVITY TO PUNISHMENT & REWARD
QUESTIONNAIRE
Are some of us more sensitive to punishment?
Are some of us more sensitive to reward?
Sensitivity to Punishment
Assign 1 point for each yes answer for odd #s
0-24 range
Sensitivity to Reward
Assign 1 point for each yes answer for even #s
High punish. Score vulnerable to anxiety. High reward score = impulsivity.
SKINNER’S EXPERIMENTS
PUNISHMENT
Punished behavior is suppressed not forgotten
Punishment teaches discrimination
did child learn not to curse or just not to curse in house?
Punishment can teach fear
Physical punishment may increase aggression
Punishment tells you what not to do; reinforcement tells you what to do
OBJECTIVE 12:
DO COGNITIVE PROCESSES & BIOLOGICAL
CONSTRAINTS AFFECT OPERANT CONDITIONING?

Extrinsic motivation
