A starchy food satiation procedure was evaluated in an ABAB withdrawal design on the post-meal rumination of a nine-year-old girl with autism. During treatment unlimited quantities of starchy foods were provided following each meal. High rates of rumination occurred during baseline conditions, followed by an immediate decrease in rumination during treatment. Rumination decreased to 82 and 97% of baseline during the ®rst and second treatment conditions, respectively. In addition, follow-up probes were conducted at irregular intervals for 4 years following treatment, during which zero or nearzero rates of rumination were sustained. This study extends the literature on the functional relation between increased starchy food quantity and rumination in adults to rumination with a young child, and demonstrates maintenance of the treatment effect for 4 years.

Class-wide behavioral interventions are a feasible and effective method to support the behavior of all students. In six peer-reviewed studies, Tootling, a class-wide intervention that combines positive peer reporting with an interdependent group contingency, has increased positive peer reports and academically engaged behavior (AEB), and decreased disruptive behavior (DB). However, no prior studies have been conducted with middle school students, and none have employed strategies to promote enduring behavior change. A withdrawal design with maintenance phase, implemented across two middle school classrooms, found moderate effects (nonoverlap of all pairs [NAP] = 0.74, Tau-U = −0.48) of Tootling on decreasing DB and moderate to large effects (NAP = 0.76, Tau-U = 0.68) on increasing AEB, although internal threats to validity prevented the demonstration of a clear functional relationship across both classrooms. Results from the maintenance phase, in which the group contingency reward was removed, suggest promising strategies to support durable behavioral change. Limitations of the present study, directions for future research, social validity, and implications for practice are discussed.

Praise and other forms of attention may not function as reinforcers for the behavior of children with autism. Previous research demonstrated that contingently pairing praise with reinforcers (response stimulus) can establish praise as a conditioned reinforcer. We evaluated a procedure for establishing praise as a generalized conditioned reinforcer (pair praise with four reinforcers) and compared it with a procedure to establish praise as a conditioned reinforcer (pair praise with one reinforcer). We compared the two condi-
