Behavior Analysis Fundamentals Practice Test

Functional analysis is a procedure that involves manipulating environmental factors—antecedents and consequences—to reveal the function of a problem behavior. By systematically changing conditions (for example, testing whether the behavior occurs more when demands are present, when attention is withheld or provided, when access to tangibles is available, or under automatic reinforcement) and observing the resulting behavior, you identify whether the behavior serves to obtain something, escape or avoid something, or is reinforced by automatic consequences. This understanding of why the behavior occurs directly informs effective intervention. The other concepts don’t fit as precisely: reinforcement describes how consequences strengthen behavior, stimulus control involves how discriminative stimuli influence responses, and single-subject research refers to a study design rather than the procedure for identifying the function of a behavior.
