Exploring the 3 Levels of Scientific Understanding in the Field of ABA

Applied Behavior Analysis (ABA) is a scientific discipline with a long history of providing effective interventions for individuals with diverse needs, including autism spectrum disorder (ASD), developmental disabilities, and mental health disorders. ABA has a systematic approach to the observation of behavior and the analysis of the factors that influence behavior. There are three levels of scientific understanding in the field of ABA: descriptive, experimental, and applied. In this article, we will explore these three levels and their significance in the practice of ABA.

Descriptive Level

The descriptive level is the initial level of scientific understanding in the field of ABA. This level involves the collection and analysis of data on the behavior of an individual. At this stage, the behavior is described in terms of its frequency, duration, and intensity. The goal of the descriptive level is to identify patterns and trends in behavior so that an effective intervention plan can be developed.

For example, if a child with ASD engages in self-injurious behavior such as head-banging, the behavior is recorded, and data is collected on the frequency, duration, and intensity of the behavior. This data is then analyzed to identify any patterns or triggers that may be contributing to the behavior.

Experimental Level

The experimental level involves the identification of variables that influence behavior and the manipulation of those variables to produce changes in behavior. This level includes the use of experimental designs to test the effectiveness of interventions.

For example, if a child with ASD engages in self-injurious behavior such as head-banging, the experimental level may involve manipulating the environment to identify any changes in behavior. This may include providing an alternative activity or providing sensory input to the child. The effectiveness of these interventions is then measured and compared to determine which intervention is most effective.

Applied Level

The applied level involves the application of ABA principles and techniques to real-world settings such as homes, schools, and communities.

For example, if a child with ASD engages in self-injurious behavior such as head-banging, the applied level may involve developing an intervention plan based on the data collected at the descriptive level and the results from the experimental level. The plan may involve the use of reinforcement to increase appropriate behaviors, the use of prompt to help the child engage in more appropriate behaviors, and the use of communication training to teach the child to express his or her needs.

Conclusion

The three levels of scientific understanding in the field of ABA are crucial in providing effective interventions for individuals with a wide range of needs. The descriptive level is important for identifying patterns and trends in behavior, the experimental level is important for identifying variables that influence behavior, and the applied level is important for applying ABA principles and techniques to real-world settings. By understanding and utilizing these three levels, behavior analysts can provide the most effective interventions for individuals and help improve their quality of life.
