<P> A functional analysis is the most direct form of functional behavior assessment, in which specific antecedents and consequences are systematically manipulated to test their separate effects on the behavior of interest . Each manipulation of the antecedent and consequence in a particular situation is referred to a condition . In a functional analysis, conditions are typically alternated between quite rapidly independent of responding to test the different functions of behavior . When data paths are elevated above the control condition (described below) it can be said that there is a functional relation between that condition and the behavior of interest . Complexity, time restraints, and setting restraints, are a few limitations to this particular method . When deciding to use this method, it should be noted that there is a chance of high - risk behavior and the possibility of low - rate behaviors . </P> <P> Below, common examples of experimental conditions are described . A standard functional analysis normally has four conditions (three test conditions and one control). </P> <P> In this condition, the experimenter gives the individual moderately preferred items and instructs them to go play . After that initial instruction, the experimenter pretends to act busy and ignores all bids for attention from the individual . If the individual engages in the behavior of interest, the experimenter provides the individual with attention (commonly in the form of a reprimand). Behaviors that occur more frequently in this condition can be said to be attention maintained . </P> <P> In this condition, the experimenter instructs the individual that it is time to work . After the initial instruction, the experimenter delivers a series of demands that the individual is typically required to complete (e.g. math problems, cleaning up, etc .). If the individual engages in the behavior of interest, the demand is removed and the child is allowed to take a break . Behaviors that occur more frequently in this condition can be said to be escape maintained . </P>

In applied behavior analysis the focus of treatment is
