The current study compared the effects of choice and no-choice reinforcement conditions on the task responding of 3 children with autism across 2 single-operant paradigm reinforcer assessments. The first assessment employed simple fixed-ratio (FR) schedules; the second used progressive-ratio (PR) schedules. The latter assessment identified the…

Individuals may prefer contexts with the option to choose between 2 reinforcing stimuli or between 2 tasks relative to contexts in which others select the same events. We evaluated children's preferences for conditions characterized by (a) the opportunity to choose between tasks and (b) the opportunity to choose between putative reinforcers…

A study evaluated the utility of a five-minute stimulus preference assessment for 20 individuals with developmental disabilities. The brief assessment identified stimuli that functioned as reinforcers for a simple operant response and identified preferred stimuli that were differentially effective as reinforcers. This assessment was associated…

Clinical applications of statistical process control (SPC) in human service organizations are considered. SPC is seen as providing a standard set of criteria that serves as a common interface for data-based decision making, which may bring decision making under the control of established contingencies rather than the immediate contingencies of…

Tangible preference assessments were compared with verbal preference assessments for six individuals (ages 15-20) with mental retardation, behavior disorders, or both. The two assessments yielded similar high-preference items for 4 of the 6 participants. The verbal assessment was typically completed in less time than the tangible assessment.…

A procedure enabling 19 adolescents/adults with profound mental retardation to express food and drink preferences was evaluated. Results indicated that active choice making occurred, and caregiver opinion was not predictive of participant preferences. Choices made using the procedure were similar to choices made when less structured opportunities…

Incorporating statistical process control (SPC) methods into applied behavior analysis is discussed. It is claimed that SPC methods would likely reduce applied behavior analysts' intimate contacts with problems and would likely yield poor treatment and research decisions. Cases and data presented by Pfadt and Wheeler (1995) are cited as examples.…

This article challenges applied behavior analysts to use their knowledge of consumer behavior and effective educational strategies to provide consumers with useful information, thereby enabling them to make informed decisions. This will decrease the misconceptions that many consumers have about behavior analysis, thus improving the social validity…

Statistical process control (SPC), which employs simple statistical tools and problem-solving techniques such as histograms, control charts, flow charts, and Pareto charts to implement continual product improvement procedures, can be incorporated into human service organizations. Examples illustrate use of SPC procedures to analyze behavioral data…
