What Is Translational Research?
Translational research is the process of taking findings from basic scientific research and applying them to solve practical problems. In behavior analysis, this means taking discoveries from experimental laboratories, often involving nonhuman subjects, and developing them into clinical interventions for human populations. The concept of translational research has gained significant attention in the behavior analytic community because it strengthens the scientific foundation of applied practice and helps close the gap between what we know from the laboratory and what we do in the clinic.
The National Institutes of Health (NIH) describe translational research as occurring along a continuum, often called the "bench to bedside" pipeline. In behavior analysis, this pipeline moves from basic behavioral research (the "bench") to applied behavioral interventions (the "bedside"), with translational studies serving as the critical bridge between the two.
Levels of Translational Research
Translational research in behavior analysis can be understood at multiple levels, each serving a distinct purpose in the research pipeline:
Basic Research
Basic research investigates fundamental behavioral processes under controlled laboratory conditions. Studies typically use nonhuman subjects (pigeons, rats) or human analogue preparations to isolate specific variables. The goal is to discover general principles of behavior, not to solve immediate practical problems. Examples include research on schedules of reinforcement, choice behavior, delay discounting, and stimulus control.
Translational Research (Bridge Studies)
Translational studies test whether basic findings hold under conditions that are more clinically relevant. These studies might use human participants, clinical populations, or analogue conditions that approximate real-world treatment settings. The goal is to evaluate the boundary conditions of basic findings and to identify variables that moderate their effects in applied contexts. For example, a translational study might test whether resurgence effects documented in pigeons also occur in children with developmental disabilities when functional communication training is disrupted.
Applied Research
Applied research evaluates interventions in real clinical settings with clinical populations. The goal is to demonstrate that an intervention produces socially significant behavior change. Applied studies must meet the criteria outlined by Baer, Wolf, and Risley (1968): the research must be applied, behavioral, analytic, technological, conceptually systematic, effective, and demonstrate generality.
Key Examples of Translational Research in ABA
From Matching Law to Concurrent Schedules Treatment
The matching law, originally derived from basic research with pigeons on concurrent schedules of reinforcement, has been translated into a framework for understanding and treating problem behavior. Herrnstein's matching law states that the relative rate of a response matches the relative rate of reinforcement for that response. Translational researchers have applied this framework to clinical settings, showing that increasing reinforcement for appropriate behavior relative to problem behavior shifts response allocation in predictable ways. This work has informed the development of differential reinforcement procedures and helped clinicians understand why some interventions fail (when the reinforcement differential is insufficient).
Delay Discounting and Impulsive Behavior
Basic research on delay discounting, the phenomenon where reinforcer value decreases as the delay to delivery increases, has been translated into clinical interventions for impulsive behavior. Translational studies have shown that individuals with developmental disabilities, substance use disorders, and attention difficulties show steeper discounting curves. Applied researchers have used these findings to develop interventions that increase tolerance for delayed reinforcement through systematic fading and stimulus bridging techniques.
Behavioral Momentum and Treatment Compliance
Behavioral momentum theory, developed through basic research on resistance to change, has been translated into the high-probability instruction sequence (high-p) procedure. Basic research demonstrated that responses reinforced at higher rates are more resistant to disruption. Translational researchers applied this principle by delivering a sequence of easy, high-probability requests before a low-probability (difficult or nonpreferred) request, using the behavioral momentum from compliance with easy requests to increase compliance with the difficult request.
Stimulus Equivalence and Language Instruction
Sidman's research on stimulus equivalence, conducted initially with laboratory participants, has been translated into efficient teaching procedures for reading, math, and language skills. By training a subset of relations and allowing the remaining relations to emerge through equivalence class formation, clinicians can achieve more learning with less direct instruction. This basic finding has transformed how behavior analysts approach academic instruction.
Why Translational Research Matters for BCBAs
Understanding translational research helps BCBAs in several practical ways:
- Evidence-based practice: Knowing the basic science behind an intervention helps you understand why it works, when it might fail, and how to troubleshoot. A BCBA who understands the matching law can predict that a differential reinforcement procedure will fail if the reinforcement rate for the alternative is not substantially higher than what the problem behavior produces.
- Innovation: Basic research findings that have not yet been translated into clinical procedures represent opportunities for innovation. BCBAs who follow the basic research literature can be early adopters of evidence-based procedures.
- Conceptual precision: Translational research reinforces the conceptually systematic dimension of applied behavior analysis. Understanding the basic principles underlying clinical procedures ensures that your practice is grounded in science rather than tradition or intuition.
- Critical evaluation: When evaluating new interventions or clinical claims, understanding the research pipeline helps you assess whether a procedure has adequate scientific support at each level of analysis.
Challenges in Translational Research
Translating basic findings to applied settings is not straightforward. Several challenges complicate the process. Laboratory conditions are carefully controlled, while clinical settings involve uncontrolled variables. Nonhuman subjects may not perfectly model human behavior, especially behaviors involving verbal mediation. Ethical constraints limit the types of manipulations possible with human participants. Publication bias may lead to underreporting of failures to translate basic findings. Despite these challenges, the translational approach has produced numerous successful clinical innovations and continues to be a vital area of behavior analytic research.
BCBA Exam Considerations
The BCBA exam may test your understanding of the relationship between basic and applied research. Know the seven dimensions of applied behavior analysis and how conceptual systematicity links applied procedures to basic principles. Be prepared to identify how basic findings (matching law, behavioral momentum, stimulus equivalence) have been translated into clinical procedures. Understand that applied behavior analysis is a science with a basic research foundation, not merely a collection of clinical techniques.
