Reducing stereotyped behavior using momentary dro: An experimental analysis

Abstract

Momentary DRO, a little-used variant of DRO, was compared with a more traditional DRO procedure in the reduction of stereotyped behavior displayed by five subjects with severe mental retardation. Momentary DRO appeared to be more effective than the traditional procedure for three subjects, less effective for one subjects and to increase the stereotyped behavior of the final subject above baseline levels, These findings are discussed in relation to response covariation effects, treatment maintenance and ease of implementation.

Dro Contingencies: An Analysis of Variable‐momentary Schedules

“…effective than momentary DRO but suggested that momentary DRO might be useful as a maintenance procedure (following the use of interval DRO). Derwas and Jones (1993) also compared interval and momentary DRO as treatments for stereotypy in 5 men who had been diagnosed with severe mental retardation. They reported that momentary DRO was more effective than interval DRO for 3 participants, that decreases in the 4th participant's stereotypy during interval DRO were maintained during a subsequent momentary DRO condition, and that momentary DRO increased the 5th participant's stereotypy.…”

“…We also used the participants' rates of responding to determine how DRO schedules were thinned. By contrast, the momentary DRO schedules used in previous research (with the exception of Derwas & Jones, 1993) were determined arbitrarily. Different results may have been obtained in the previous studies if different, perhaps richer, schedules had been used.…”

“…With the exception of some of the results obtained by Derwas and Jones (1993), findings from the above studies suggest that interval DRO is a more effective intervention than momentary DRO. Although differences in results obtained with the two procedures might be attributed to a number of variables (e.g., type of reinforcer used, selection of interval length, resetting feature, etc.…”

“…Görüldüğü üzere en ılımlı uygulamalar pekiştirmeye dayalı uygulamalardır ve bu uygulamaların kullanılmasının uygun olmayan davranışların azaltılmasında oldukça etkili olduğu alanyazında sıkça vurgulanmaktadır (Barton, Brulle ve Repp, 1986;Derwas ve Jones, 1993;Tavil, 1996).

Reducing stereotyped behaviour: A comparison of two methods of programming differential reinforcement1

“…Some authors have claimed considerable success with momentary DRO compared with the more traditional schedule (e.g. Denvas & Jones, 1993;Sisson, Van Hasselt, Hersen & Aurand, 1988), whereas others have found whole-interval DRO to be more successful.…”
