Notes on John B. Watson and the Little Albert Experiment

John B. Watson and The Behavior School of Psychology

  • John B. Watson

    • Established The Behavior School of Psychology.
    • Conducted influential studies in psychology during the 1920s.

  • Classical Conditioning

    • Initially experimented by Ivan Pavlov.
    • Defined as a learning process where an unconditioned stimulus (UCS) elicits an unconditioned response (UCR), while a conditioned stimulus (CS) elicits a conditioned response (CR).
    • Pavlov's experiments famously involved a dog.

The Little Albert Experiment

  • Experiment Overview

    • Watson extended classical conditioning to human subjects through the Little Albert experiment.
    • Baby Albert was born to a nurse in the Harriet Lane home for invalid children and showed a normal development despite his hospital environment.
    • Watson aimed to condition a fear response in a human, similar to Pavlov’s work with dogs.

  • Conditioning Process

    • Initially, Watson presented Albert with objects he liked:
    • Fire, a monkey, a dog, a rabbit, and a white rat.
    • Little Albert showed a positive reaction, especially towards the white rat.

  • Inducing Fear Response

    • The conditioning began when Albert reached for the rat:
    • A loud noise (bar striking) was produced each time he touched it, startling him.
    • Initially startled, Albert did not cry immediately but did on a second attempt.
    • The fear response was successfully conditioned:
    • When shown a rabbit, he cried and withdrew.
    • His response was more cautious with a dog, only crying when it got too close.
    • He also reacted negatively to a fur coat and a Santa Claus mask, indicating generalization.

  • Generalization Phenomenon

    • Albert's fear of the rat extended to other similar objects (generalization).
    • Watson conducted further tests in a larger room to see if fear responses would continue in different settings.

  • Persistence of Fear

    • Upon returning one month later, Albert was tested again:
    • The same objects were presented with the loud noise.
    • Albert displayed strong withdrawal responses, proving persistence of conditioned fear.

  • Conclusions by Watson

    • Watson concluded that phobias can be learned responses, as demonstrated by the Little Albert study.
    • This study has had significant implications in psychology, influencing future researchers and shaping behavioral investigations.

Impact on Psychology

  • Significance of Little Albert Study
    • Highlighted the potential for conditioning in humans and the development of fears and phobias.
    • Established foundational theories in behavioral psychology that continue to influence the field today.
  • Component Process Theory
    • Discusses visual processing being less complex than mathematical concepts.
    • Proposes the existence of three pairs of color receptors:
    • Red, green; yellow, blue; black, white.
