A recent study described a synthesized treatment where a functional analysis was based on an open-ended interview and combined with functional communication and delay-tolerance training. The treatment resulted in a reduction in problem behaviors and an increase in appropriate requests. Most of the analysis and intervention were done in a clinic setting, and required weekly visits by the family. This present study is a systematic replication, where we conducted the same synthesized treatments, with a young child with Autism Spectrum Disorder (ASD) enrolled in a home-based Early Intensive Behavior Intervention program, EIBI. Outcomes were similar with a marked reduction in problem behaviors and an increase in appropriate requests. These findings suggest that it is possible to conduct this intervention in a home setting, with weekly consultations with parents. Our study show the utility of the synthesized treatment in an EIBI program in a home setting and how this can contribute to client time and costs.
A systematic replication of Watt, Keenan, Barnes, and Cairns (1991) was conducted on two groups of Norwegian soccer supporters. The 24 participants were trained conditional discriminations for the emergence of three 3-member equivalence classes, when members of two of the classes were assumed to be part of the participants' preexperimental history. The stimuli used in these classes were pictures or names of soccer players relevant to their own team or the rivaling team. Participants were trained in a linear training structure before the test. The test was split into three test blocks. Test Block 1, a replication of Watt et al.'s (1991) equivalence test, Test Block 2 an adapted generalization test and Test Block 3 an updated equivalence test. The results in Test Block 1 replicated what was found in 1991, but Test Block 3 did not replicate the same results. In Test Block 2, participants scored as expected and the response patterns were distinctly different between the test groups and the Control Group. Also, the time used to finish the experiment by the soccer team supporters were significantly higher than by participants who had no interest in soccer. This difference was also reflected in the reaction times the participant showed on the emergent relations in test blocks 1 and 3. A correlation was found between the number of expected scores on the questionnaire and the number of passes in Test Block 1. However, no correlation was found in the number of participants who passed in Test Block 3. The study by Watt et al. (1991) was not found to generalize to the context in the current study. However, the extended parts in the study had some promising results on how social categorization can be studied in the derived stimulus paradigm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
