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 three algorithms most frequently selected by behavior-analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with…

The present study demonstrated the relative impact of gambling and nongambling contexts on the degree of delay discounting by pathological gamblers. We used a delay-discounting task with 20 pathological gamblers in and out of the natural context in which they regularly gambled. For 16 of the 20 participants, it appeared that the difference of…

Three experiments were conducted involving five people with profound multiple disabilities, to determine whether variations in alertness affected subsequent responsiveness to training programs. Findings suggest that existing levels of alertness do not indicate how individuals will respond during training and that alertness actually can be…

Five experiments with severely retarded noncompliant males made use of behavioral momentum to increase compliance. A series of commands with which the subject was very likely to comply were issued immediately prior to issuing a low-probability command. Results indicated increased compliance and decreased compliance latency and task duration.…

Experiments examined the effect of work requirements in combination with reinforcement schedules on the choice behavior of six adults with mental retardation and seven typical preschoolers. Results showed that participants' responding was largely controlled by the reinforcement received for responding to each level of work. (Author/CR)

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.…
