This study assessed whether tact training would establish analogies as measured by equivalence-equivalence relations. In Experiment 1, six college students were trained to tact "same" or "different" in the presence of AB and BC compounds based on component class membership (e.g., A1B1 as "same", and A1B2 as "different"), and then tested on emergent tacts (BA, CB, AC, CA) and equivalence-equivalence relations. Only one of six participants passed all tests without remedial training. In Experiment 2, six college students were trained to tact only compounds belonging to the same class as "same". Three of six participants passed all tests without remedial training. In Experiment 3, six college students were trained to tact stimuli belonging to the same class with a common name prior to exposure to relational tact training. All participants passed tests without remedial training. In Experiment 4, eight college students were trained to tact stimuli belonging to the same class with a common name. Six participants passed without remedial training, while two, who did not tact the relation of the compounds, did not. Results from these studies suggest that simple discrimination of individual components and their relation in the form of tacts is related with equivalence performance.

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.

In an effort to provide clarity about the unique contributions of several professions within the context of multidisciplinary treatment, we reviewed the definitions, philosophical underpinnings, and national requirements pertaining to both scopes of practice (i.e., model licensing acts, legislation, and regulatory boards) and training (i.e., task lists, accreditation standards and course requirements, and exam blueprints) of 4 behavioral health professions. The professions we selected (behavior analysis, psychology, speechlanguage pathology, and occupational therapy) are likely to provide treatment alongside one another and often to the same clients. In a review of documents pertaining to scopes of practice and training for each profession, we found overlapping content. However, the similarities between professions diminished when we reviewed more specific guidelines such as learning objectives, educational requirements (i.e., coursework), supervised clinical experience (e.g., internships), and national examinations. This was especially true when considering each profession's underlying approach to treatment (i.e., philosophical underpinnings) and, hence, service activities. We discuss our findings in light of service overlap and make a call for greater collaboration between professions, as related to the separate content knowledge and expertise of professionals in each field and the impact on client outcomes.Keywords Scope of practice .

Collaboration According to the Centers for Disease Control and Prevention (CDC), the current rate of prevalence for a diagnosis of autism spectrum disorder (ASD) in children is estimated to be approximately 1 in 59 (CDC, n.d.). In a study conducted by Cawthorpe (2017), it was reported that the current literature on the prevalence of ASD reports rates of approximately 1%-4% in the general population (i.e., including children and adults), making it a ubiquitous health concern.Additionally, comorbidity has been documented as occurring among those with ASD for decades (Matson & Nebel-Schwalm,

According to traditional linguistic accounts language, and its generative nature, cannot be taught. From a behavior analytic perspective, language is like any other behavior; it is learned and amenable to change. Based upon Skinner's radical behavioral analysis of verbal behavior, specific procedures have been designed to promote novel verbal relations. However, despite the strength and utility of this approach, using behavioral principles to understand the generativity of language has been challenging. Dependent upon the specific theory (e.g., stimulus equivalence, relational frame theory, bidirectional naming) within the radical behavioral orientation, researchers arrange unique procedures to evaluate the variables responsible for this phenomenon. This paper presents the commonalities and differences of two procedures (i.e., multiple exemplar training, multiple exemplar instruction) with examples of research highlighting the use of both in producing generativity. Further, it describes how multiple exemplar instruction is independent from other procedures leading to this outcome, and concludes by providing recommendations for both research and practice.

The current study examined the effectiveness of an experimental functional analysis for assessing the functions of emergent vocal-verbal behavior in children with developmental disabilities. Experiment 1 consisted of a systematic replication of Lerman et al. (2005). Participants were 3 children with developmental disabilities, between the ages of 2 and 5 years, with limited vocal-verbal repertoires, who could emit at least two clear vocalizations. Results indicated that for all participants, targeted vocalizations functioned as mands, tacts, or both. The purpose of Experiment 2 was to address some of the limitations of Experiment 1 while using a different experimental design. Results of Experiment 2 suggested that participants' targeted vocalizations served as tacts, echoics, or both. Results are discussed in terms of the utility of this methodology for the selection and development of effective language interventions as well as implications for our current knowledge of verbal behavior.
