1. Reinforces and Punishment
BY HEIDI TENNEY

2. Reinforcement
 The process by which a stimulus increases
the probability that a preceding behavior
will be repeated.

3. Positive Reinforcement
 A stimulus added to the environment that brings
about the increase in a preceding response.
 Example: A father gives candy to his son after he
picks up his toys.

4. Negative Reinforcement
 An unpleasant stimulus whose removal leads to an
increase in the probability that a preceding
response will be repeated in the future.
 Example: Class is boring so you doodle on your
paper or fall asleep.

5. Punishment
 A stimulus that decreases the probability
that a previous behavior will occur again.

6. Positive Punishment
 Punishment that weakens a response through the
application of an unpleasant stimulus.
 Example: Getting a speeding ticket and having to
complete 48 hours of community service.

7. Negative Punishment
 Punishment that consists of the removal of
something pleasant.
 Example: Taking away your kids car keys for being
home after curfew.
