Operant Conditioning: Topography vs. Function

Introduction to Operant Conditioning and the Robustness of Behaviorism

  • Perspective of the Speaker: Doctor Howard, a behavior analyst by training, introduces the topic of operant conditioning.
  • Criticism of Introductory Psychology Textbooks: Doctor Howard asserts that most introductory textbooks oversimplify behavioral theory. There is a specific intent to move beyond these oversimplifications to demonstrate how robust and effective behaviorism is for changing behavior.
  • Goal of the Lectures: The upcoming videos aim to address common misconceptions held by psychologists about behaviorism and behavioral theory to clarify its complexity and utility.

The Legacy and Philosophy of B.F. Skinner

  • Career Scope: Skinner had an extensive career dedicated to researching behavior.
  • Focus Areas: Much of his research was centered on the effective implementation of reinforcement.
  • Stance on Punishment: Skinner argued at length regarding the philosophical and practical dangers of using punishment. He advocated against the ubiquitous use of punishment within society.
  • The Ethical Goal of Behaviorists: The primary focus of behavioral analysts is to improve the quality of life for clients. The objective is to ensure that behavioral changes result in meaningful, positive outcomes for individuals.

Topography vs. Function: The Core Misconception

  • Common Student Misunderstanding: The first major misconception often introduced in textbooks involves the distinction between the topography of a stimulus and its function.
  • Topography (Form):
    • Definition: Topography, or form, refers to the physical appearance or description of a stimulus—"what it looks like."
    • The Error of Assumptions: Many people (and textbooks) incorrectly assume that because a stimulus seems pleasant or is something an individual says they like, it will automatically act as a reinforcer.
  • Function:
    • Definition: Function refers to the actual effect a stimulus has on behavior—"what it actually does."
    • Determining Behavior Procedures: To determine if a procedure is one of reinforcement or punishment, one must look at the effect produced on the future rate of behavior.

Case Study: The Cookie Example (Reinforcement and Motivation)

  • The Scenario: Billy is given a cookie after performing a behavior (e.g., cleaning his room).
  • The Theoretical Question: What is the most important part of this relationship? Is it the form (the cookie itself) or the effect on behavior?
  • Textbook vs. Behavioral Reality:
    • Textbooks might suggest the cookie is the most important part because it is a "reward."
    • In behavior analysis, a cookie is not a reinforcer for everyone, nor is it a reinforcer for the same person at all times.
  • The Role of Satiation and Motivation: If Billy has just finished a very large meal, the offer of a cookie to wash a car will likely fail to change his behavior because he is not motivated by that specific stimulus at that time. In this instance, the topography of the stimulus is irrelevant because it lacks the function of reinforcement.

Case Study: The Swatting Example (Defining Punishment vs. Reinforcement)

  • The Scenario: A child learning table manners talks back and is subsequently swatted or spanked.
  • Topographical View: In everyday language, swatting is labeled as punishment because it involves physical striking or aversives.
  • Functional View:
    • Scenario A (Punishment): If the child talks back less in the future after being swatted, the procedure functioned as punishment. A decrease in future behavior confirms the procedure is punishment.
    • Scenario B (Reinforcement): If the child talks back more in the future following the swatting, the procedure functioned as reinforcement. An increase in future behavior confirms the procedure is reinforcement, regardless of how "aversive" the stimulus appears.

Summary of Essential Principles

  • Proof of Change: One cannot conclude that a "reward" functions as a reinforcer or that an "unpleasant" stimulus functions as a punisher without empirical evidence of behavior change.
  • Requirement for Analysis: Effective behavioral procedures require observing the future rate of behavior to provide proof of the function of the consequence.
  • Future Content: Subsequent lectures will address misconceptions regarding basic behavior change procedures.
