Study Guide on Applied Behavior Analysis

Chapter 1: Definition and Characteristics of Applied Behavior Analysis

Overview of Applied Behavior Analysis (ABA)

  • Definition:

    • Applied Behavior Analysis (ABA) is defined as the science dedicated to understanding and enhancing human behavior.

    • It involves a collection of facts about observed events that can be quantified, classified, and examined for potential relationships with other known facts (i.e., systematic observation).

    • The goal of ABA is to create functional relations derived from scientific discoveries.

  • Functional Relation:

    • Exists when a well-controlled experiment demonstrates that a specific variable (the dependent variable, DV) is reliably produced by another variable (the independent variable, IV), while minimizing the influence of extraneous factors (confounding variables).

Learning Objectives

  • Understand the basic characteristics and goals of science within the context of ABA.

  • Explain behavior according to the philosophical assumptions of behavior analysis.

  • Define determinism as it pertains to behavior analysis.

  • Differentiate between mentalistic and environmental explanations of behavior.

  • Describe and analyze behavior using behavior analytic terminology.

  • State and explain each dimension of applied behavior analysis.

  • Recognize that the purpose of science in ABA is to achieve a comprehensive understanding of phenomena related to socially significant behavior change.

Levels of Scientific Understanding

  • Three Main Levels of Science:

    • Description: Clearly specifying observations of phenomena.

    • Prediction: When repeated observations show that two events consistently correlate with one another.

    • Control: Manipulating variables to control behavior and determine cause-and-effect relationships.

Assumptions and Attitudes of Science

Key Concepts in Scientific Methodology

  • Determinism:

    • Assumes the universe operates under lawful and orderly principles; nothing occurs purely by accident.

    • Everything happens for a reason.

  • Empiricism:

    • Emphasizes objective observation and measurement of phenomena.

    • Scientific understanding builds on layers of empirical data.

  • Experimentation:

    • Constitutes a fundamental strategy involving comparisons of phenomena under different conditions.

    • Only one factor (the independent variable, IV) should differ across conditions for clarity.

  • Replication:

    • Requires that experiments be repeated until a consistent and reliable outcome is achieved.

  • Parsimony:

    • Advocates for simple, logical explanations, ruling out more complex hypotheses initially.

  • Philosophic Doubt:

    • Encourages ongoing skepticism about the truth of assumed facts.

    • It suggests that one should question the validity of what is labeled as truth.

Behaviorism and Its Historical Background

Philosophy of Behavior Science

  • Behaviorism:

    • The foundational philosophy of the science of behavior.

  • Basic Research vs. Applied Research:

    • Basic research concerns the preservation of the experimental analysis of behavior (EAB).

    • Applied behavior analysis (ABA) focuses on the technology designed to enhance behavior.

Definition of Science

  • Science is a systematic method for understanding natural phenomena:

    • Grounded in description, prediction, and control.

    • Functions according to the principles of determinism, empiricism, experimentation, replication, parsimony, and philosophical doubt.

Brief History of Behavior Analysis

  • Behavior analysis comprises three interrelated domains: philosophy, basic research, and applied research.

  • Major Influences:

    • Watson’s Behaviorism: Known as stimulus-response (S-R) psychology. Watson advocated for direct observation of behavioral relationships between environmental stimuli (S) and responsive reactions (R).

    • Mentalism: An approach assuming a mental dimension distinct from observable behavior.

    • Explanatory Fiction: Refers to observed behavior that does not enhance understanding of the underlying variables.

    • Pragmatism: Philosophical stance where the truth of a statement is evaluated based on its practical effects and ability to promote effective action.

The Experimental Analysis of Behavior

Foundational Contributions

  • Founded by B.F. Skinner, published in The Behavior of Organisms in 1938.

    • Types of Behavior:

    • Respondent Behavior: Reflexive and involuntary behaviors elicited by antecedent stimuli.

      • Example: A bright light (stimulus) causes pupil constriction (response).

    • Operant Behavior: Behavior influenced by the consequences that follow it, rather than preceding stimuli.

    • Key Formula: The interaction of stimuli and responses is characterized by the S-R-S (Stimulus-Response-Stimulus) three-term contingency.

    • Hypothetical Constructs: Presumed variables that cannot be directly manipulated in experiments and may influence the observed behavior.

Characteristics of Applied Behavior Analysis

Three Branches of Behavior Analysis

  • Radical Behaviorism:

    • Attempts to explain all behavior, including both thoughts and feelings.

  • Experimental Analysis of Behavior:

    • Focuses on dissecting behavior through rigorous experimentation.

  • Applied Behavior Analysis:

    • Involves systematic application of behavioral principles to enhance socially significant behavior.

    • Research and experimentation inform practice to discover variables responsible for behavior change.
