In this paper I discuss (a) three steps in the development of establishing
operation (EO) terminology, (b) my early neglect of its possible relevance
to applied behavior analysis, (c) the importance of functional analysis met
hodology for increasing awareness of EO issues, and (d) three comprehensive
reviews that clarify the role of EOs in applied work. I then review and fu
rther analyze seven topics that require further clarification or that have
been raised since my 1982 and 1993 articles: the EO evocative effect, depri
vation and satiation, problem behavior maintained by attention, decreasing
behavior evoked by a transitive conditioned establishing operation, EOs in
the context of escape and avoidance, academic demand, and decreasing behavi
or evoked by a reflexive conditioned establishing operation.
