If particular parameters (e.g., reinforcer quality) are found to be preferred in a concurrent-operant arrangement, then these should be incorporated into interventions for maintaining skills in individuals with intellectual disabilities. However, because results from a concurrent-operant arrangement may not predict those of a single-operant assessment, interventions with less preferred parameters may also be effective. The purpose of this study was to determine if preference for a particular parameter, determined via concurrent-operant arrangements, predicted responding when two values of highly and less preferred parameters were manipulated in a single-operant arrangement. Participants allocated responding to one parameter over another during concurrent-operant assessments, indicating that certain parameters were highly preferred. However, contingent presentation of two values of less preferred parameters increased compliance to similar levels achieved with two highly preferred parameters in a single-operant arrangement. These findings suggest that clinicians may have multiple options when selecting parameters for use during intervention.
如果在并发操作安排中发现某些参数（例如，强化物质量）更受青睐，那么这些参数应该被纳入到智力障碍个体的技能维持干预中。然而，由于并发操作安排的结果可能无法预测单项操作评估的结果，因此具有较少首选参数的干预也可能是有效的。本研究的目的是确定通过并发操作安排确定的特定参数的偏好是否可以预测在单项操作安排中操纵两个高度和较少首选参数值时的反应。参与者在并发操作评估中分配对一个参数的反应而不是另一个参数的反应，这表明某些参数具有高度的偏好。然而，两个不太受青睐的参数值的偶然呈现增加了对与单项操作安排中两个高度受青睐的参数所达到的相似水平的依从性。这些发现表明，临床医生在选择干预期间使用的参数时可能有多种选择。
