Functional Analysis Of Behavior

Page Status: Reviewed

A number of procedures are often described as a “Functional analysis” of behavior.

Definition: Procedures where either antecedents and consequences or consequences alone are  systematically manipulated to evaluate the  effects of their presence or absence on rates of behavior. A  functional analysis may take any one of the following forms:

1. Analog Functional Analyses:

2. Trial based Functional Analyses:

3.  Single Subject Experimental designs may be considered an “analysis” in conditions where the subject of the analysis is the “function” of a specific behavior or behaviors


All of these systematic manipulations and this they are functional analyses of behavior. A common misconception is that the term functional analysis refers only to  an analog functional analysis.
