In ABA, which approach is used to analyze the purpose behind behaviors?

The correct answer, functional behavior assessment, is a systematic process used in applied behavior analysis (ABA) to identify the reasons behind specific behaviors. This approach typically involves direct observation, interviews, and sometimes data collection on antecedents and consequences surrounding the behavior in question. The goal is to understand what maintains the behavior, whether it be gaining attention, escaping a task, obtaining a tangible item, or fulfilling some other need.

Functional behavior assessments result in the development of a hypothesis regarding the function of the behavior, allowing practitioners to create effective intervention strategies tailored to the individual's needs. This method is critical in ABA, as it ensures that interventions are based on the actual purposes that behaviors serve, leading to more successful outcomes in behavior modification.

While other approaches like experimental analysis involve manipulating variables to observe effects on behavior, they are not specifically focused on identifying behavioral purposes in the same structured way as functional behavior assessments do. Behavioral statistics refer to the quantitative data analysis that is used to interpret behaviors but does not directly analyze the underlying purposes. Qualitative assessment encompasses various methods to gather non-numerical data but lacks the specific systematic approach to understanding behavior function characteristic of functional behavior assessments.
