Stereotypical behavior maintained by automatic reinforcement often does not result in harm but may be undesirable in some situations. In the current investigation, participants were 2 individuals who engaged in nonharmful stereotypical responses shown in an analogue functional analysis to be insensitive to social contingencies. After bringing…

The current study evaluated the use of various behavioral measures of running away with regard to (a) the differential utility of interval- versus event-based measures, (b) the differential utility of rate versus duration measures, (c) the utility of correcting for occurrence opportunity, and (d) the influence of unit of analysis (i.e.,…

Although previous research indicates that certain types of attention (i.e., statements related to behavior, tickles) may be differentially reinforcing, only one or two forms of attention are typically provided contingent on problem behavior during the attention condition in experimental functional analyses. In the present investigation, various…

The authors suggest that line graphs that average response frequency over long periods obscure the major rate changes that indicate sources of behavioral control. A scatter plot can make patterns of responding identifiable and, in turn, suggest environmental features that occasion undesirable behavior. Use of scatter diagrams is illustrated in…

This study assessed the validity of idiosyncratic choice-making behaviors of three children with multiple disabilities. Children were given either their "choice" of food or drink or were given the opposite. Direct observations of children's acceptance or refusal revealed the children consistently indicated choices during both conditions.…

Functional assessment is redefining the standards for clinical interventions with problem behavior and reemphasizing the importance of basic behavioral mechanisms. It has shown the importance of complex patterns of behavioral control, functional assessment as an ongoing process, and the importance of attention to antecedent variables. Future…

Three experiments were conducted with two participants with mental retardation that displayed property destruction and stereotypy. The experiments assessed the function of the responses, determined their relationship, and developed a treatment to reduce property destruction. Response blocking reduced property destruction (and attempts), prevented…

A large-scale analysis was conducted of problem behavior by observing 20 individuals living in residential facilities. Data were converted into scatter plot formats. When the data were transformed into aggregate "control charts," 12 of 15 sets of data revealed 30-minute intervals during which problem behavior was more likely to occur.…

The representativeness of behavioral observation samples with durations of less than the whole time of interest was investigated with five profoundly mentally retarded physically handicapped adults in an institutional setting. It was found that the session representativeness was a function of the relative duration of the behavioral categories and…

This paper summarizes brief functional assessments of 79 cases of people with developmental disabilities and self-injurious, aggressive, stereotypic, or other aberrant behavior. Outcomes were evaluated across three variables: (1) referring topography, (2) control over behavior, and (3) the identified maintaining conditions for aberrant behavior.…

A functional analysis involving antecedent events was conducted with four students identified as having behavior problems. Off-task behavior was measured while task difficulty and level of adult attention was manipulated during analog sessions. Results revealed higher rates of off-task behavior during difficult tasks and improved behavior when…
