All rights reserved Basic Characteristic of Science Systematic approach for seeking & organizing knowledge about the natural world Purpose To achieve a thorough understanding of the phenomena under study ABA – socially important behaviors Seeks to discover the real truths (not those held by certain groups, organizations, etc.) Basic Characteristic of Science Three different types of investigations provide different levels of understanding: 1. Description 2. Prediction 3. Control Basic Characteristic of Science Description Collection of facts about observed events that can be quantified, classified, & examined for possible relations with other know facts Often suggests hypotheses or questions for additional research Basic Characteristic of Science Prediction Relative probability that when one event occurs, another event will or will not occur Based on repeated observation revealing relationships between various events Demonstrates correlation between events No causal relationships can be interpreted Enables preparation Basic Characteristic of Science Control Highest level of scientific understanding Functional relations can be derived Specific change in one event (dependent variable)…. Can reliably be produced by specific manipulations of another event (independent variable)… And the change in the dependent variable was unlikely to be the result of other extraneous factors (confounding variables) Events can only really be “co-related” Nearly impossible to factor out all other possible “causes” Attitudes of Science Scientific attitudes that guide the work of all scientists include: Determinism Empiricism Experimentation Replication Parsimony Philosophic doubt Attitudes of Science: Determinism Assumption upon which science is predicted Presumption that the universe is a lawful and orderly place in which all phenomena occur as the result of other events Events do not just occur at will Events are related in systematic ways Attitudes of Science: Empiricism Practice of objective observation of phenomena of interest What all scientific knowledge is built upon “Objective” is the key to gaining a better understanding of what is being studied Attitudes of Science: Experimentation Basic strategy in most sciences Experiment: Controlled comparison of some measure of the phenomenon of interest (dependent variable) under two of more different conditions in which only one factor at a time (independent variable) differs from one condition to another Attitudes of Science: Replication The repetition of experiments to determine the reliability and usefulness of findings Includes the repetition of independent variable conditions within experiments Method for which mistakes are discovered Attitudes of Science: Parsimony The idea that simple, logical explanations must be ruled out, experimentally or conceptually, before more complex or abstract explanations are considered Help scientists fit findings within the field’s existing knowledge base Attitudes of Science: Philosophic Doubt The continuous questioning of the truthfulness and validity of all scientific theory and knowledge Involves the use of scientific evidence before implementing a new practice, then constantly monitoring the effectiveness of the practice after its implementation A Definition of Science Science is… A systematic approach to the understanding of natural phenomena… As evidenced by description, and control… That relies on determinism as its fundamental assumption… Empiricism as its prime directive… Experimentation as its basic strategy… Replication as its necessary requirement for believability… Parsimony as its conservative value… And philosophic doubt as its guiding conscience. Development of Applied Behavior Analysis Behavior analysis is comprise of three major branches 1. Behaviorism Philosophy of the science of behavior 2. Experimental analysis of behavior (EAB) Basic research 3. Applied behavior analysis (ABA) Development of a technology for improving behavior Can only be understood in the context of the philosophy & basic research traditions & findings Development of Applied Behavior Analysis Psychology in the early 1900’s was dominated with the study of states of consciousness, images, & other mental processes Development of Applied Behavior Analysis Watson is recognized as moving the field of psychology in a new direction Argued that subject matter for psychology should be the study of observable behavior, not states of mind or mental processes Early form of behaviorism known as stimulus-response (S-R) psychology (Watsonian behaviorism) Created foundation for the study of behavior as a natural science Development of Applied Behavior Analysis B.F. Skinner’s The Behavior of Organisms (1938/1966) Formally began the experimental branch of behavior analysis Summarized his laboratory research from 1930-1937 Discussed two types of behavior Respondent Operant Development of Applied Behavior Analysis Respondent behavior Reflexive behavior Ivan Pavlov (1927/1960) Respondents are elicited (“brought out”) by stimuli that immediately precede them Antecedent stimulus & response it elicits form a functional unit called a reflex Involuntary responses Occur whenever eliciting stimulus is present S-R model Development of Applied Behavior Analysis Operant behavior Behavior is shaped through the consequences that immediately follow it Three term contingency (Antecedent, Behavior, Consequence) S-R-S model (Stimulus, Response, Stimulus) Behaviors that are influenced by stimulus changes that have followed the behavior in the past Development of Applied Behavior Analysis Experimental analysis of behavior (EAB): Named as a new science by Skinner Outlined specific methodology for its practice: The rate or frequency of response is the most common dependent variable Repeated or continuous measurement is made of carefully defined response classes Within-subject experimental comparisons are used instead of designs comparing the behavior of experimental & control groups Visual analysis of graphed data is preferred over statistical inference A description of functional relations is valued over formal theory testing Very influential in the guiding practice of the science of behavior & in proposing the application of the principles of behavior to new areas Walden Two (1948) Science and Human Behavior (1953) About Behaviorism (1974) Philosophy of science became known as radical behaviorism Development of Applied Behavior Analysis Radical behaviorism (Skinner’s behaviorism) makes three assumptions about the nature of private events Private events such as thoughts and feelings are behavior Behavior that takes place within the skin is distinguished from other (“public”) behavior only by its inaccessibility Private behavior has no special properties & is influenced by (i.e. is a function of) the same kinds of variables as publicly accessible behavior Development of Applied Behavior Analysis Mentalism Approach to understanding behavior that assumes that a mental or “inner” dimension exists that differs from a behavioral dimension & that phenomena in this dimension either directly cause or at least mediate some forms of behavior Relies on hypothetical constructs and explanatory fictions Dominated Western intellectual thought & most psychological theories (e.g. Descartes, Freud, Piaget) A fictitious variable that often is simply another name for the observed behavior that contributes nothing to an understanding for the variables responsible for developing (or maintaining) the behavior Circular view of the cause & effect Development of Applied Behavior Analysis Structuralism (Wundt and Titchener) Rejects all events that are not operationally defined by objective assessment Restrict activities to descriptions of behavior Make no scientific manipulations; do not address causal questions Development of Applied Behavior Analysis Methodological behaviorism (Watson) Rejects all events that are not operationally defined by objective assessment Deny existence of “inner variables” or consider them outside the realm of scientific account Acknowledge the existence of mental events but do not consider them in the analysis of behavior Use scientific manipulations to search for functional relationships between events between events that can be observed publicly Development of Applied Behavior Analysis Skinner did not object to cognitive psychology’s concern with thoughts & feelings (i.e. events taking place “inside the skin”) Referred to these as “private events” They are behavior to be analyzed with the same conceptual & experimental tools used to analyze publicly observable behavior Development of Applied Behavior Analysis Fuller (1949) One of the first studies to report the human application of operant behavior Participant: 18-year-old boy with profound mental retardation Arm-raising response was conditioned by injecting a small amount of a warm sugar-milk solution into participant’s mouth every time he moved his right arm Development of Applied Behavior Analysis Ayllon & Michael (1959) “The Psychiatric Nurse as a Behavioral Engineer” Formed the basis for branch of behavior analysis that would later be called applied behavior analysis (ABA) Described techniques based on principles of behavior to improve the functioning of chronic psychotic or mentally retarded residents Development of Applied Behavior Analysis 1960’s Researchers began to apply principles of behavior in an effort to improve socially important behavior Techniques for measuring behavior & controlling & manipulating variables were sometimes unavailable, or inappropriate Little funding was available No ready outlet for publishing studies Difficult to communicate findings Development of Applied Behavior Analysis Despite limitations in the 1960’s many applications of behavior principles were made Application of behavior principles to education is a major area of impact Provided the foundation for: ✓behavioral approaches to curriculum design ✓instructional methods ✓classroom management ✓generalization and maintenance of learning Development of Applied Behavior Analysis 1960’s & 1970’s Many new university programs were developed in applied behavior analysis Teaching & research conducted in these programs made major contributions to the rapid growth of the field Development of Applied Behavior Analysis 1968 – Formal beginning of contemporary applied behavior analysis Journal of Applied Behavior Analysis (JABA) began publication “Some Current Dimensions of Applied Behavior Analysis” (Baer, Wolf, & Risley) Development of Applied Behavior Analysis Journal of Applied Behavior Analysis (JABA) First journal in U.S. To deal with applied problems & gave researchers using methodology from the experimental analysis of behavior an outlet for publishing their findings Flagship journal of ABA Development of Applied Behavior Analysis “Some Current Dimensions of Applied Behavior Analysis” (Baer, Wolf, & Risley) Founding fathers of the new discipline (ABA) Defined the criteria for judging adequacy of research & practice in ABA & outlined the scope of work for those in the science Most widely cited publication in ABA Remains standard description of the discipline Defining Characteristics of Applied Behavior Analysis Baer, Wolf, and Risley (1968) recommended the following seven defining dimensions for research or behavior change programs: Applied Behavioral Analytic Technological Conceptual Effective Generality Defining Characteristics of Applied Behavior Analysis Applied Investigates socially significant behaviors with immediate importance to the participant(s) Examples include behaviors such as: Social Language Academic Daily living Self-care Vocational Recreation and/or leisure Defining Characteristics of Applied Behavior Analysis Behavioral Precise measurement of the actual behavior in need of improvement & documents that it was the participant’s behavior that changed The behavior in need of improvement and it is a study of behavior (not about behavior) The behavior must be measurable Important to note whose behavior has changed Defining Characteristics of Applied Behavior Analysis Analytic Demonstrates experimental control over the occurrence and non- occurrence of the behavior (a functional relation is demonstrated) Functional & replicable relationships Defining Characteristics of Applied Behavior Analysis Technological Written description of all procedures in the study is sufficiently complete and detailed to enable others to replicate it All operative procedures are identified and described in detail & clarity Replicable technology Defining Characteristics of Applied Behavior Analysis Conceptually systematic Behavior change interventions are derived from basic principles of behavior Better enable research consumer to derive other similar procedures from the same principle(s) Assist in integrating discipline into a system instead of a “collection of tricks” Defining Characteristics of Applied Behavior Analysis Effective Improves behavior sufficiently to produce practical results for the participant(s) Improvements in behavior must reach clinical or social significance Extent to which changes in the target behavior(s) result in noticeable changes Defining Characteristics of Applied Behavior Analysis Generality Produces behavior changes that last over time… Appear in other environments (other than the one in which intervention was implemented)… Or spread to other behaviors (those not directly treated by the intervention) Definition of Applied Behavior Analysis Applied behavior analysis is: A scientific approach to improving socially significant behavior… In which procedures derived from the principles of behavior are systematically applied to improve socially significant behavior… And to demonstrate experimentally that the procedures employed were responsible for the improvement in behavior Definition of Applied Behavior Analysis Six key components: 1. Guided by attitudes of methods of scientific inquiry 2. All behavior change procedures are described & implemented in a systematic, technological manner 3. Only procedures conceptually derived from the basic principles of behavior are circumscribed by the field 4. Focus is socially significant behavior 5. Seeks to make meaningful improvement in important behavior 6. Seeks to produce an analysis of the factors responsible for improvement Domains of Behavior Analytic Science Four domains Behaviorism Experimental analysis of behavior (EAB) Applied behavior analysis (ABA) Professional practice Behavior analysts may work in one or more of the four domains Domains are very interrelated & influence one another Domains of Behavior Analytic Science Behaviorism Theoretical & philosophical issues Conceptual basis of behavior principles as it relates across many spectrums Domains of Behavior Analytic Science Experimental analysis of behavior (EAB) Basic research Experiments in laboratory settings with both human participants and nonhuman subjects Goal of discovering & clarifying fundamental principles of behavior Domains of Behavior Analytic Science Applied behavior analysis (ABA) Applied research Experiments are aimed at discovering & clarifying functional relations between socially significant behavior & its controlling variables Desire to contribute to further development of a humane & effective technology of behavior change Domains of Behavior Analytic Science Professional practice Providing behavior analytic services to consumers Design, implement, & evaluate behavior change programs that consist of behavior change tactics derived from fundamental principles of behavior Discovered by basic researchers Experimentally validated for their effects on socially significant behavior by applied researchers
