Unlabelled: Research has found equivalence-based instruction (EBI) to be effective and efficient, with recent research extending these finding to individuals diagnosed with autism spectrum disorder (ASD). EBI has also been compared with more traditional approaches to teaching, such as traditional lectures, reading assignments, and video lectures. However, the authors are unaware of any comparisons of EBI to other similar behavior analytic approaches such as discrete trial teaching (DTT).

Historically, teaching procedures based on applied behavior analysis (ABA), including discrete trial teaching (DTT), have been provided and evaluated via in-person delivery. This study sought to compare the implementation of DTT via direct telehealth to DTT implemented in-person within and across participants.

Another strategy that may have benefits would be to arrange the stimuli in view of the learner. The purpose of this study was to compare the relative effectiveness and efficiency of arranging the stimulus array in view versus out of view of the learner when teaching receptive labels to three children diagnosed with autism spectrum disorder.

The COVID-19 pandemic has highlighted the need for effective social skills interventions that can be delivered directly via telehealth. The Cool Versus Not Cool procedure has continually been documented as effective within the literature.
View Article and Find Full Text PDFTelehealth research in the field of applied behavior analysis (ABA) has focused on the training and supervision of others to implement various behavior analytic procedures. Current guidelines for practicing telehealth suggest that direct telehealth services may be appropriate for some individuals diagnosed with autism spectrum disorder, but more research is needed. This study evaluated the effects of discrete trial teaching with instructive feedback in a dyad arrangement delivered directly via telehealth to teach tact relations to 6 children diagnosed with autism spectrum disorder.

The RBT® was created based upon the requests of stakeholders who wanted to credential those individuals who make direct contact with clients under the supervision of a Board Certified Behavior Analyst®. There has been tremendous growth in the number of RBTs® with over 60,000 individuals certified to date.

Research has demonstrated the effectiveness of both procedures, as well as compared them. The majority of these studies have been completed through the use of single-subject experimental designs.

View Article and Find Full Text PDFToken systems often involve a predetermined number of tokens required prior to exchange for a terminal reinforcer. The effectiveness of token systems implemented in this manner has been well documented within the literature; however, some have discussed the possibility of a fixed earning requirement creating a context in which the learner no longer emits the desired behavior once the terminal number is achieved. A possible alternative to a fixed earning requirement is selecting the earning requirement based upon learner responding and leaving the requirement unknown to the learner until the moment of exchange.

Three commonly used prompting systems include constant time delay, most-to-least prompting, and flexible prompt fading. Most of the research demonstrating the effectiveness of these three prompting strategies have been completed through the use of single subject experimental designs.

The teaching interaction procedure consists of labeling the targeted skill, providing a meaningful rationale for the importance of the skill, describing the steps of the targeted skill, modeling the skill, and providing feedback throughout the interaction. Although the teaching interaction procedure has been used to teach a variety of social skills to children and adolescents diagnosed with autism spectrum disorder (ASD) and other social and behavioral disorders, its use has not been evaluated for training staff.
View Article and Find Full Text PDFCurrent practice guidelines suggest that the assessment and treatment of challenging behavior should consist of conducting a functional behavior assessment following the onset of problem behavior. This assessment process can include indirect and direct assessment, as well as manipulation of variables to determine function. The purpose of this article is to outline a proposal that would add prevention practices to early intervention guidelines for problem behavior.
View Article and Find Full Text PDFLevel systems have been described as a framework which can be used to shape behavior through the systematic application of behavioral principles. Within level systems, an individual moves up and down through various levels contingent upon specific behaviors. Although level systems are commonly used within schools and other settings, they have a limited empirical literature base, and there is debate over the efficacy and overall acceptance of level systems.

The effects of retinoids are mediated through 2 families of retinoid receptors: retinoic acid receptors (RARs) and retinoid X receptors (RXRs), with alpha (α), beta (β), and gamma (γ) subtypes in each family. To date, no data exist on the expression pattern of retinoid receptors in lungs of cattle, dogs, and pigs.

However, the role and even the reality of Pleistocene forest refugia have attracted much scepticism. In Amazonia, previous phylogeographical studies have focused mostly on organisms found in the forests themselves, and generally found speciation events to have predated the Pleistocene.

The peripheral blood BCR-ABL/ABL ratio, as assessed by Q-RT-PCR, has been shown to correlate with the contemporary cytogenetic response in patients receiving imatinib (Glivec, Gleevec). We have used Q-RT-PCR to monitor the early molecular response to 4 weeks and 3 months of imatinib therapy, in 47 patients with established CML.
View Article and Find Full Text PDFImatinib mesylate (trade name Glivec or Gleevec) is emerging as an important therapy in the management of chronic myeloid leukaemia (CML). It is clinically useful to monitor the cytogenetic response to imatinib, although frequent marrow examinations are inconvenient. We have used serial real-time reverse transcription-polymerase chain reaction (RT-PCR) to monitor the ratio of peripheral blood BCR-ABL to normal ABL transcripts in 43 patients receiving imatinib, and compared the results to concurrent conventional bone marrow (BM) cytogenetics.
