Ivan Pavlovs Experiments

Pavlov was a Russian physiologist (1849-1936).

He conducted famous experiments in the early 1900s.

His research led to the concept of classical conditioning: The Russian physiologists early twentieth-century experiments now psychologys most famous research are classics, and the phenomenon he explored we justly call classical conditioning.

John B. Watsons Influence

Pavlov’s work influenced psychologist John B. Watson.

• Watson wanted psychology to focus only on observable behavior, not inner thoughts.

• He believed psychology should aim for the “prediction and control of behavior.” (Quote from Watson, 1913)

• He argued that “introspection forms no essential part of its methods.” (Quote from Watson, 1913)

• Behaviorism

• Watson’s approach was called behaviorism: “This view, which Watson called behaviorism, influenced North American psychology, especially during the first half of the twentieth century.”

• It became popular in North America in the early 1900s.

• Both Pavlov and Watson rejected the idea of studying “mentalistic” concepts (such as consciousness).”

• They believed “the basic laws of learning were the same for all animals — whether dogs or humans.

Modern Psychologys View

Today, most researchers disagree with ignoring mental processes.

However, they agree that classical conditioning is a basic form of learning by which all organisms adapt to their environment.

Behaviorism views learning as a process based on observable behavior rather than thoughts or emotions. According to behaviorism:

• Learning happens through interactions with the environment.

• Behavior is shaped by rewards and punishments.

• Internal thoughts and feelings are not important for studying learning.

• All animals (including humans) learn in the same way.

John B. Watson, a key behaviorist, stated that psychology should focus on “the prediction and control of behavior” and that “introspection forms no essential part of its methods.”

Later, B.F. Skinner expanded on behaviorism with operant conditioning, which emphasizes learning through consequences (reinforcement and punishment).
