Burrhus Frederic Skinner was an influential American psychologist who developed the theory of operant conditioning. Operant conditioning states that behavior is learned through reinforcement and consequences from past experiences. There are key principles of operant conditioning: behaviors followed by rewarding consequences like rewards or removal of negative stimuli will likely be repeated, while behaviors followed by negative consequences like punishment or removal of rewards will likely not be repeated. Behavior modification applies these principles of reinforcement to strengthen desired behaviors.

history or past experiences,
particularly those that were
repeatedly reinforced.

7. All behavior is learned.
Consequences result from
behavior – reward and
punishment
Behavior that is rewarded
with reinforcers tends to
recur.

8. Positive reinforcers that
follow a behavior increase
the likelihood that the
behavior will recur.
Negative reinforcers that
are removed after a
behavior increase the
likelihood that the behavior
will recur.

9. Continuous reinforcement
is the fastest way to
increase that behavior, but
the behavior will not last
long after the reward
ceases.

11. Behavior Modification
A method of attempting to
strengthen a desired
behavior or response by
reinforcement – either
positive or negative.
