Several studies have shown that children prefer contingent reinforcement (CR) rather than yoked noncontingent reinforcement (NCR) when continuous reinforcement is programmed in the CR schedule. Preference has not, however, been evaluated for practical schedules that involve CR. In Study 1, we assessed 5 children's preference for obtaining social interaction via a multiple schedule (periods of fixed-ratio 1 reinforcement alternating with periods of extinction), a briefly signaled delayed reinforcement schedule, and an NCR schedule. The multiple schedule promoted the most efficient level of responding. In general, children chose to experience the multiple schedule and avoided the delay and NCR schedules, indicating that they preferred multiple schedules as the means to arrange practical schedules of social interaction. In Study 2, we evaluated potential controlling variables that influenced 1 child's preference for the multiple schedule and found that the strong positive contingency was the primary variable. © Society for the Experimental Analysis of Behavior.

We compared the effects of escape extinction (EE) plus noncontingent reinforcement (NCR) with sensory integration therapy as treatment for the feeding problems of 2 children. Results indicated that EE plus NCR was more effective in increasing acceptance, decreasing inappropriate behavior, and increasing amount consumed relative to sensory integration for both children. The results are discussed in terms of the challenges of evaluating sensoryintegration-based treatments, and the reasons why component analyses of multicomponent treatments like sensory integration are important.

The purpose of the current investigation was to identify an appropriate texture for initial treatment of 1 child's feeding problem. Variability in mouth clean (a product measure of swallowing) during a texture assessment suggested that individual pureed foods differentially affected feeding behavior. A single-food assessment identified individual problematic foods. We used the results of these assessments to inform treatment, resulting in high levels of mouth clean across foods. © Society for the Experimental Analysis of Behavior. Source
