Association for Behavior Analysis International

Behavior analysts are increasingly called to serve culturally and linguistically diverse populations. However, it is unclear the extent to which race, gender, and linguistic diversity are addressed in ABA practice (Talk 1). In addition, it is unclear the extent to which language of instruction affects skill acquisition for individuals from dual language households (Talk 2). After focusing on the role of diversity and language in practice, we will present the results of two studies. The first study evaluates the effect of interventionist’s language on speech generating device language output and challenging behavior for a child with Down syndrome. The second study presents the results of a culturally adapted behavioral consultation framework for the Latino population. Finally, as a leader in this area of Behavior Analysis, Dr. Jeannie Aguilar, will discuss the studies, findings, and implications for research and practice.

Researchers in Applied Research (graduate students, doctoral students, post-doctoral and professors) and practioners working with culturally and linguistically diverse populations.

Diversity may be defined along a number of dimensions including, but not limited to the presence of a variety of genders, races, ethnicities, languages, and socio-economic statuses (Silverman, 2010). As a field, ABA has made great strides in some areas of diversity. This study investigates the results of survey polling individuals in the field of ABA related to racial and gender identity, linguistic diversity (e.g., primary language), and presence of diversity related coursework in training programs either in progress or completed. Results related to formal training on diversity training within programs (e.g., BACB Verified Course Sequences), recruitment of traditionally underrepresented populations, and continuing education will be discussed, as well as recommendations to address areas of need.

Recent research has suggested language of instruction may have an effect of the behavior of children with autism spectrum disorder during instructional sessions. This study aims to add to the literature base by evaluating effects of instructional language on skill acquisition during instructional settings. There were two participants for this study. Both of the children were diagnosed with autism spectrum disorder. Both of the participants came from a Spanish speaking family but received instruction primarily in English. Skill acquisition was evaluated using novel responses in both English and Spanish with the schedule of reinforcement held constant. Results indicate that language of instruction did not have an impact for the participating students. Potential moderating factors will be discussed

Individuals with disabilities whose family members speak a language other than English and communicate using speech generating devices (SGDs) require assessment of instructional language and programmed language output of the SGD. In this study, an alternating treatment design was used to examine the effect of interventionist language as a putative motivating operation (English or Spanish) on the (a) choice of SGD language output, (b) frequency of mands, and (c) frequency of challenging behavior for a 10-year old non-verbal child with Down syndrome. Results indicated a slight increase in manding when the interventionist spoke Spanish compared to the English or control conditions. The participant also manded most frequently in Spanish on the SGD, suggesting a preference for Spanish output. These results indicate a potential preference for instructional language and expressive language using an SGD. Challenging behavior was observed more frequently in the English and control conditions. The implications of this research were discussed in the context of potential motivating operations for communication. The ethical practices and standards of Board Certified Behavior Analysts (BCBAs) and educators were also addressed.
