Traditionally, behavior analysts have studied stimulus equivalence using a matching-to-sample (MTS) preparation. Although researchers have shown the utility of MTS to yield equivalence classes, the procedure requires several prerequisite skills for a learner to accurately respond. Previous research with humans and nonhumans has shown that relational responding can be produced via compound stimulus discrimination and successive matching-to-sample (S-MTS). We conducted four experiments with college students to further evaluate the effectiveness of S-MTS in the establishment of stimulus relations. S-MTS trials consisted of the presentation of a single sample stimulus followed by one comparison in a fixed location on a computer screen. Depending upon the sample-comparison relation, participants touched (i.e., go) or did not touch (i.e., no-go) the comparison stimulus. Following training of the baseline relations (AB/BC), we assessed the emergence of symmetry, transitivity, and equivalence performances (i.e., BA/CB and AC/CA). Results support the utility of the S-MTS procedure as a possible alternative to traditional MTS. This study has direct implications for participants for whom traditional three-array MTS procedures may be challenging.

Rapid eating, a potentially dangerous and socially inappropriate behavior, has received relatively little attention in the literature. This study sought to extend the research in this area by further evaluating the effectiveness of a vibrating pager combined with a rule for increasing inter-response time between bites in one adolescent female diagnosed with autism. Results indicated that inter-response time increased from baseline only after a vocal prompt to "wait" was introduced across clinic and home settings. Implications for promoting autonomy in individuals with developmental disabilities are discussed.This antecedent-based intervention can easily be generalized to caregiversThe unobtrusive nature of the intervention allows for implementation in inclusive settingsThere are implications for promoting social skills in naturalistic environmentsThe intervention can promote independence through teaching self-management.

Dependent group contingencies offer an efficient way to improve the behavior of an entire group of students, as the performance of only one or a few students needs to be monitored at a time. Prior literature reviews outlined the use of group contingency interventions with children in educational settings; however, these reviews did not exclusively examine dependent group contingencies or the varied conditions under which this intervention has been implemented. The purpose of this review was to classify the settings, populations, outcome measures, intervention components, and procedural parameters of dependent group contingencies across the research literature. We completed electronic database searches between 1970 and 2019 for experimental studies in APA PsycINFO, ERIC, CINAHL, CINHAL Complete, Psychology and Behavioral Sciences Collection, Education Source, Academic Search Ultimate, and ProQuest and ancestral searches for the exact terms “dependent group contingenc*” OR “dependent group-oriented contingenc*” in the title, abstract, or author-defined keywords. The results of our review are summarized and discussed in terms of directions for future research and implications for practice.
