A Comparison of Baseline Procedures in Task Analyses.
Several methods for assessing baseline performance in chained tasks have been outlined in the literature, including the fixed-opportunity probe (FOP) and the multiple-opportunity probe (MOP). Concerns have been raised regarding how each of these methods might change the baseline performance of a task, affecting the interpretation of experimental control. The purpose of the current study was to conduct a within-subject comparison of both the FOP and MOP procedures for children with autism performing daily living and self-care skills. Results indicated that, for most participants, the MOP resulted in elevated performance during baseline compared to the FOP, and that for some participants the MOP resulted in acquisition prior to direct training. Because of the possibility that the FOP might result in suppressed baseline performance, it is recommended that in most cases clinicians and researchers use the MOP when assessing baseline performance in chained tasks in order to obtain the most accurate data.
期刊介绍:
For two decades, researchers and practitioners have turned to Behavior Modification for current scholarship on applied behavior modification. Starting in 1995, in addition to keeping you informed on assessment and modification techniques relevant to psychiatric, clinical, education, and rehabilitation settings, Behavior Modification revised and expanded its focus to include treatment manuals and program descriptions. With these features you can follow the process of clinical research and see how it can be applied to your own work. And, with Behavior Modification, successful clinical and administrative experts have an outlet for sharing their solutions in the field.
