Punishment
Punishment
Is a basic principle of behavior
Is derived from basic and applied
research
May be a component of some behavior
modification procedures
Defining Punishment
1. The occurrence of a behavior
2. Is followed immediately be a consequence
3. The behavior is less likely to occur in the
future (decrease in the future probability of
the behavior)
Present ---> Behavior is followed by a
consequence
Future ----> Behavior is less likely to occur
What is Positive Punishment?
1. Following the behavior
2. A stimulus (aversive stimulus or
punisher) is applied or presented
3. The behavior is less likely to occur in
the future
What is Negative Punishment?
1. Following the behavior
2. A stimulus (reinforcer) is withdrawn or
removed
3. The behavior is less likely to occur in
the future
What is a Punisher?
The stimulus that follows the behavior
that results in a decrease in the future
probability of the behavior
Also called an aversive stimulus
Reinforcers vs Punishers
When a punisher is delivered following a behavior,
the behavior is less likely to occur (decreases) in the
future. (positive punishment)
When a punisher is removed following a behavior,
the behavior is more likely to occur (increases) in the
future. (negative reinforcement)
When a reinforcer is delivered following a behavior,
the behavior is more likely to occur (increases) in the
future. (positive reinforcement)
When a reinforcer is removed following the behavior,
the behavior is less likely to occur (decreases) in the
future. (negative punishment)
Unconditioned Punishers
Events that have biological importance
Punishers that require no conditioning
to be effective
Examples:
painful stimuli,
extreme levels of stimulation (heat, cold,
auditory, visual)
removal of unconditioned reinforcers
Conditioned Punishers
A previously neutral stimulus
Is paired with an established punisher
Becomes a punisher itself
Examples of conditioned punishers **
“no”, reprimands, threats, warnings,
facial expressions of disapproval
** Determined by their effect on the behavior
Factors Influencing Punishment
Immediacy
Contingency
Establishing operations
Intensity
Individual differences
Potential Problems with
Punishment
Emotional reactions to punishment
Negative reinforcement for the use of
punishment
