Definition

The title of this Wikipedia entry is listed as a Fundamental [Functional] Assessment [of Behavior (FAB)], however the body of the entry discusses Functional Behavior Assessment (FBA). It is important to note that although these two assessments have similarities, they are not synonymous. By definition, a Functional Behavior Assessment (FBA) is an assessment that is used to obtain information about the hypothesized purpose of problem behaviors. The information gathered once a FBA is completed, guide the strategies outlined in a Behavior Intervention Plan (BIP). FBAs are conducted by a variety of appropriately trained professionals. Conversely, a Functional Assessment of Behavior is an assessment that can clearly identify the functional relationship between behavior and environment. The hypotheses associated with FABs are tested using an experimental design and are usually conducted by Board Certified Behavior Analysts (BCBA).        

                                                 

Functions of Problem Behavior

Behavior can be simply be described as the observable things people do. Behavior is viewed as being purposeful for specific antecedents due to the contingencies involved. A contingency is defined as a chronological relationship between behaviors and consequences (Cipriani, 2011) There are two classes of behavior: respondent behavior and operant behavior. Respondent behavior are involuntary responses that require no prior learning to take place and is elicited by environmental stimuli, i.e. blinking when water splashes in your eyes, snatching your hand away when you touch something hot (Pennington, 2019. )
