Due to the prevalence of words that cannot be read phonetically in the English language, sight word instruction is required to supplement phonics instruction. In this study, we manipulated stimulus disparity in sight word sets by comparing the effects of sets of sight words with the same initial letter (3 words per set, 3 total sets) versus distributing words with the same initial letter across sets when assessing acquisition of the combined set (9 words) for 5 children who ranged from 4–6 years of age using a combined adapted alternating treatments design and pre‐posttest design. All participants mastered the 3‐word sets in both teaching conditions but did not master the control sets. In general, participants required more teaching sessions when the words in sets began with the same letter. These findings are consistent with stimulus disparity research demonstrating that discrimination training is generally less efficient when comparison stimuli are similar. [ABSTRACT FROM AUTHOR]

Although the use of differential reinforcement has been recommended in previous investigations and in early intervention curriculum manuals, few studies have evaluated the best method for providing differential reinforcement to maximize independent responding. This paper reviews previous research on the effectiveness of differential reinforcement as treatment and describes important areas of future research. [ABSTRACT FROM AUTHOR]

Response to name (RTN) is an early developmental milestone, deficits in which are associated with autism spectrum disorder (ASD). This study extends previous research by evaluating an assessment and treatment model for RTN with 13 children with ASD. For all participants, phase 1 was a naturalistic social baseline. The 9 children who did not meet mastery criteria in phase 1 underwent a series of treatment conditions in phase 2. In phase 3, treatment components were removed, and generalization was assessed. Results indicated that tangible reinforcement procedures can produce rapid increases in discriminated RTN, sometimes without prompts. The total number of trials to mastery were reduced in the current study relative to previous research. Results also provide preliminary evidence to suggest that the phase 1 baseline condition may produce distinct patterns of RTN that could be used to predict treatment effects and further reduce trials to mastery in future work.

Students who fail to acquire foundational literacy skills during preschool are more likely to read below grade level average in elementary school and are at a heightened risk for future school failure, poverty, early mortality, and crime. The purpose of this study was to compare the effects and maintenance of and preference for paired kinesthetic movements (KM) to a traditional drill (TD) procedure on letter–sound correspondence and word recognition with 6 preschool children. In 6 of 11 evaluations, participants mastered the KM set in substantially fewer intervention sessions than the TD set. In 5 of 11 evaluations, participants mastered the KM and TD sets with little differentiation between the number of intervention sessions. No participant mastered the control set. Maintenance data demonstrate a higher number of correct responses for the KM condition across all weeks. Preference varied across participants and was not always consistent with the more effective intervention. [ABSTRACT FROM AUTHOR]

Deficits in response to name (RTN) are an early indicator of autism spectrum disorder (ASD), and RTN is a treatment goal in many early intervention curricula for children with ASD. However, little research has empirically evaluated methods for increasing RTN in children with ASD. We evaluated a series of conditions designed to increase RTN for 4 children with ASD using a multielement experimental design. The schedules of tangible reinforcement were thinned after mastery and generalization was tested across people and contexts. Tangible reinforcers were necessary to increase RTN for all 4 participants, and the schedule of reinforcement was successfully thinned with all participants after intervention. Generalization was also observed across people and experimental contexts. [ABSTRACT FROM AUTHOR]

This study examined the effects of intercontinental telehealth coaching on the mastery of therapists' skills and improvements in verbalizations by children with autism, testing whether telehealth can be a solution for underserved communities in developing countries such as Georgia-Sakartvelo in Eastern Europe. Three therapists delivering and three children with autism receiving early-intervention services from the nongovernmental organization Children of Georgia in Tbilisi participated. Experimenters provided coaching from Virginia, USA to therapists in Georgia-Sakartvelo. Observers in Georgia-Sakartvelo and in Virginia conducted the behavioral observations. We used inexpensive communications technology to provide the coaching and a multiple-baseline design across participants to evaluate the effects of the intervention. Therapists demonstrated improvements in two classes of behaviors: correct command sequences and positive consequences. The children demonstrated improvements with echoics and mands. The study demonstrated that telehealth can be a good model for delivering early-intervention services to children with autism in underserved and distant regions of the world. [ABSTRACT FROM AUTHOR]

This study evaluated the effects of programmed treatment-integrity errors on skill acquisition for children with an autism spectrum disorder (ASD) during discrete-trial instruction (DTI). In Study 1, we identified common treatment-integrity errors that occur during academic instruction in schools. In Study 2, we simultaneously manipulated 3 integrity errors during DTI. In Study 3, we evaluated the effects of each of the 3 integrity errors separately on skill acquisition during DTI. Results showed that participants either demonstrated slower skill acquisition or did not acquire the target skills when instruction included treatment-integrity errors. [ABSTRACT FROM AUTHOR]

Many early intervention curricular manuals recommend teaching auditory-visual conditional discriminations (i.e., receptive labeling) using the simple-conditional method in which component simple discriminations are taught in isolation and in the presence of a distracter stimulus before the learner is required to respond conditionally. Some have argued that this procedure might be susceptible to faulty stimulus control such as stimulus overselectivity (Green, 2001). Consequently, there has been a call for the use of alternative teaching procedures such as the conditional-only method, which involves conditional discrimination training from the onset of intervention. The purpose of the present study was to compare the simple-conditional and conditional-only methods for teaching receptive labeling to 3 young children diagnosed with autism spectrum disorders. The data indicated that the conditional-only method was a more reliable and efficient teaching procedure. In addition, several error patterns emerged during training using the simple-conditional method. The implications of the results with respect to current teaching practices in early intervention programs are discussed. [ABSTRACT FROM AUTHOR]
