Title: Operant Conditioning


1
OPERANT CONDITIONING Learning in which a certain
action is reinforced or punished, resulting in
behavioral change
2
B.F. Skinner is best known for his work with the
operant conditioning theory.
Believed that how we turn out is a direct result
of what we learn from all of the operations
(operant) that we make over the years

Reinforcement is something that follows a
response and strengthens the tendency to repeat
that response
PRIMARY SECONDARY REINFORCERS
Primary reinforcement is something that is
necessary for survival. Ex food or water
Secondary reinforcement is a stimulus that we
have learned to value (linked to a primary
reinforcer)
5
Positive Reinforcement
  • Positive consequence that increases the chance of
    desired behavior because something is added ()
    or presented.
  • Can be thought of as a reward!
  • Getting a present on X-mas for being
  • Good all year

6
Negative reinforcement is when something that is
unpleasant is stopped or taken away when
something is done
Headache stops when you take Tylenol so you
strengthened the behavior of taking Tylenol
Reinforcement always strengthens a response,
rather than weakening it.
7
Punishment involves decreasing the frequency of a
behavior.
Punishment always weakens a response, rather than
strengthening it.
8
Operant Conditioning
There are two types of consequences
  • positive (sometimes called pleasant)
  • negative (sometimes called aversive)

9
Operant Conditioning
Two actions can be taken with these stimuli
  • they can be ADDED to the learners environment.
  • they can be SUBRACTED from the learners
    environment.

Billy likes to campout in the backyard. He
camped-out on every Friday during the month of

kids snuck up to his tent while he was sleeping
and threw a bucket of cold water on him. Billy
has not camped-out for three weeks.
1. What behavior was changed?
Camping out

kids snuck up to his tent while he was sleeping

2. Was the behavior strengthened or weakened?
Weakened (Behavior decreased)
We Eliminate positive and negative reinforcement

Since a consequence was ADDED and the behavior
was WEAKENED (REDUCED), the process was Positive
Punishment.
