In-Depth Notes on Behaviorist Approaches to Personality

Learning Objectives

  • Understand classical and operant conditioning principles in personality.
  • Explore how these principles apply to unusual personality reactions and problem behaviors.
  • Consider the broader implications of behaviorism.

Overview of Behaviorism

  • Behaviorism emerged as a reaction against psychology's focus on unobservable phenomena (like introspection and unconscious motives).
  • Personality is viewed as observable and measurable behavior, emphasizing observable actions over internal states.

Key Concepts in Behaviorism

  • Radical Behaviorism: (e.g. B.F. Skinner)

    • Focuses strictly on observable behavior without considering internal states.
    • Key Components:
    1. Stimulus: the trigger for behavior.
    2. Response: the measurable action following the stimulus.
    3. Reinforcement/Punishment: affects the likelihood of the response repeating.

  • Moderate Behaviorism: (e.g. Social Learning Theorists, Cognitive Behaviorists)

    • Acknowledges the importance of internal states (habits, thoughts, motives) in explaining behavior.

Classical Conditioning

  • Definition: A learning process where a previously neutral stimulus becomes associated with an unconditioned stimulus to elicit a conditioned response.

    • Example: Pavlov's Dogs
    • US (Unconditioned Stimulus): Food
    • UR (Unconditioned Response): Salivation
    • CS (Conditioned Stimulus): Bell
    • CR (Conditioned Response): Salivation upon hearing the bell.

  • Applications:

    • Little Albert Experiment: Demonstrated fear conditioning by associating a loud noise (US) with a white rat (CS), leading to generalized fear responses.
    • US: Loud noise
    • UR: Fear
    • CS: Rat
    • CR: Generalized fear reaction to similar stimuli.

  • Curing Phobias:

    • Methods such as Extinction (exposing the phobia without reinforcement) or Systematic Desensitization (pairing relaxation with the fear stimulus) are used for treatment.

Operant Conditioning

  • Definition: A method of learning that employs rewards and punishments for behavior.

  • Reinforcement: Increases behavior.

    • Positive Reinforcement: Adding a pleasant stimulus to enhance behavior (e.g. praise).
    • Negative Reinforcement: Removing an unpleasant stimulus to increase behavior (e.g. stopping a loud alarm).

  • Punishment: Decreases behavior.

    • Positive Punishment: Adding an unpleasant stimulus to reduce behavior (e.g. failing an exam).
    • Negative Punishment: Removing a pleasant stimulus to reduce behavior (e.g. losing driving privileges).

  • Examples:

    • Positive Reinforcement: Praising Lauren for cleaning her room, leading to more frequent cleaning.
    • Negative Reinforcement: Ashley keeps hitting snooze, reinforcing behavior by stopping the alarm noise.
    • Positive Punishment: Jenna's co-worker's cookies decrease Robert's office visits.
    • Negative Punishment: Yu stops mentioning his marriage to continue getting attention from women.

Schedules of Reinforcement

  • Variable Ratio: Reinforcement occurs after unpredictable numbers of responses, common in gambling or social media habits.
  • Fixed Ratio and Interval: Reinforcement delivered consistently after specific ratios or intervals of responses or time.

Broader Implications of Behaviorism

  • Questions about free will and human nature are raised, particularly regarding how behaviorism influences changes in personality and human behavior.
  • B.F. Skinner suggested that reliance on behaviorist principles limits personal freedom and autonomy.

Conclusion

  • Behaviorist theories provide a framework for understanding personality development through observable behavior, emphasizing the impact of environmental influences and learned responses over inherent traits or unconscious motivations.
