An experimental methodology for understanding why a behavior problem occurs, in terms of environmental functions, has received extensive attention and development (Bailey & Pyles, 1989; Iwata, Dorsey, Slifer, Bauman, & Richman, 1982; Iwata, Vollmer, & Zarcone, 1990; Lalli, Browder, Mace, & Brown, 1993; Lerman & Iwata, 1993; Lennox & Miltenberger, 1989; Lerman & Iwata, 1993, Mazelski, Iwata, Vollmer, Zarcone, & Smith, 1993). The efficacy of using functional analysis of behavior paradigms (AKA analogue assessment) to discern consequent controlling variables has received extensive empirical support since the original study in 1982 (Iwata, et.al., 1982). A functional analysis of problem behavior empirically extracts the context conditions under which such a behavior becomes more probable. Its heightened rate can be explained by both the presenting motivational conditions as well as the utility of such a behavior to produce a stimulus change that addresses the client's motivational condition. Cipani & Schock (2007) have designated sub-categories within four major environmental functions, in their classification system (see Table 1). This function-based diagnostic classification system classifies problem behaviors according to their environmental function. Operant behaviors are maintained by either positive or negative reinforcement operations. The manner in which the reinforcers are produced can be either socially mediated (i.e., through the behavior of another) or directly (behavior produces reinforcer). For example, a child throws tantrums in the afternoon before dinner. Such behaviors reliably result in access to food items, under conditions of relative deprivation, by her parent eventually giving the child a small snack. Tantrum behavior resulted in access to snack (positive reinforcement operation), but the result was mediated by her parent (i.e., socially mediated behavior problem or SMA 2.3: access to tangible reinforcers in diagnostic system). Snack items could be obtained by another child under similar motivating conditions by coming home and grabbing some cookies when parent is not watching (i.e., pilfering the cookie jar). The operation is the same, but the manner in which the reinforcer was obtained was not socially mediated. Rather it was directly produced via the chain of behaviors referred to as pilfering. While much is known about why a problem behavior occurs at an unacceptable rate, little to date has been done with developing a methodology to discern why the rate (or lack thereof) of the alternate behavior is relatively low. What would be the utility of such an analysis? An experimental analysis of the problem behavior allows the user to design functional interventions that address the controlling variables of that behavior. The same result could also be achieved from an experimental analysis of the contextual variables of the alternate replacement behavior. Such an analysis could lead to the design of effective interventions prior to any false starts. Consider the following hypothetical example. A client in a residential facility is referred for a functional behavioral assessment for engaging in self-injury. Reports from staff and descriptive data seem to indicate that this behavior is maintained as a result of socially mediated escape from unpleasant social situations (see Cipani & Schock, 2007). When other client's get near him when he is playing with his preferred toy, he screams and begins hitting himself. Such behavior usually brings staff, with the result of being separated from other clients. To test this hypothesis of a socially mediated escape function experimentally, an analogue assessment is set up. In a contrived setting, two test conditions will be implemented in a multi-element design: (1) client is in therapy room with other clients with his preferred toys and (2) client is in room with other clients without his preferred toys. …
