We examined articles in the "Journal of Applied Behavior Analysis" in which results of functional analyses indicated that problem behavior was maintained by multiple sources of reinforcement. Data for 88 (16.9%) of 521 subjects reported in 168 studies met the criteria for multiple control. Data for 11 subjects (2.1%) involved a single response…

This commentary summarizes methodological and conceptual issues in functional analysis methodologies and offers some suggestions for their resolution. Considered are increasing complexity, absence of contingencies during assessment, use of subtle manipulations, alternative assessment strategies, analysis of antecedent influences on behavior,…

To the extent that applied behavior analysis represents a scientific and practical approach to the study of behavior, its technological character is essential. The most serious problem evident in the field is not that the research being done is too technical but that more good research of all types is needed. (JDD)

Discussion of the functional relationship between self-injurious behavior (SIB) and self-restraint in people with severe disabilities considers SIB and self-restraint as members of the same functional response class, SIB and self-restraint as functionally independent responses, access to self-restraint as positive reinforcement of SIB, termination…

Results of a functional analysis indicted that the hand mouthing of a woman with profound mental retardation was maintained by multiple sources of control (sensory stimulation and access to a leisure item). Hand mouthing, though maintained by automatic reinforcement, was also susceptible to social contingencies when exposed to them during…
