“All we need to know in order to
describe and explain behavior is this: actions followed by good
outcomes are likely to recur , and actions followed by bad
outcomes are less likely to recur.” - Skinner, 1953
- Behaviorism is a philosophy of psychology, which has a
profound influence on the understanding of mental and behavioral
aspects of life.
- Behaviorist theory is based on the concept of learning which
refers to a relatively permanent change in behavior or knowledge
due to experience.
- Behaviorism originated in Russia with Ivan Petrovich Pavlov
- Behaviorism as a discipline was founded by John Watson
- Skinner and Thondike extended the theory.
Respondent Learning/Classical Conditioning
- This theory was formulated by a Russian psychologist called
- It is based on a stimuli-response formula.
- Pavlov presented his theory by his famous experiment, a dog
learned to salivate to the sound of a bell, if the bells were
rung simultaneously with the presentation of food.
- Developed by B. F. Skinner (1904-1990) and JB Watson.
- "Humans were simply more complicated than animals but operated
on the same principles" - Watson
- This theory states that when learning is rewarded, behavior is
perpetuated or maintained, while punished behavior is removed.
- In the classic experiment of “Skinner Box”, a rat may receive
a food reward every time he presses the bar. He presses
faster and faster.
- Techniques in operant conditioning are:
- Positive reinforcement - increasing a behavior by
administering a reward.
- Negative reinforcement - increasing a behavior by removing
an aversive stimulus when a behavior occurs
- Punishment - decreasing a behavior by administering an
- Extinction - decreasing a behavior by not rewarding it.
- Several psychotherapeutic interventions have been developed
based on behaviorism for conditions such as phobia, anxiety
disorders and behavior problems in children.
- These theories have been applied in educational psychology for
developing and refining methods of teaching.
- Behaviorism is a developmental theory that measures observable
behaviors produced by a learner’s response to stimuli.
- Behaviorist theory influenced the understanding of human
activities- acting, thinking, and feeling.
