Previous research has demonstrated that patterns of responding during a no-interaction condition of a functional analysis (FA) may predict FA outcomes. Thus, behavior analysts may use an initial no-interaction condition to identify problem behavior maintained by social reinforcement when time and resources are limited. However, in a clinic setting, most functional analyses are conducted in between or immediately after instructional sessions or structured play. Therefore, the proposed study was designed to examine the differential effects of presession conditions of naturally occurring activities (work versus play) at a clinic setting during a modified brief functional analysis. Results showed that presession conditions did not affect rates of responding for behaviors maintained by automatic reinforcement. Implications and future directions are discussed.
