The Basics of CBM: What BCBAs Need to Know.

Curriculum-based measurement (CBM) is an approach to measuring student academic growth and evaluating the effectiveness of instruction (Deno, Exceptional Children, 52, 219-232, 1985) that was developed, in part, based on characteristics of applied behavior analysis. Learning to administer and use CBM data is commonly part of teacher preparation programs, but less common in behavior analysis graduate programs (Schreck et al. Behavioral Interventions, 31, 355-376, 2016; Schreck & Mazur, Behavioral Interventions, 23, 201-212, 2008). This article describes a sequence of steps that educational teams can follow to use CBM within the multi-tiered system of support (MTSS) framework. These steps include (1) selecting a CBM publisher and gathering materials; (2) practicing administering and scoring CBM; (3) administering, scoring, and comparing student scores to grade-level benchmarks; (4) using CBM data to write ambitious and realistic IEP goals; and (5) using data-based individualization. Each step is described and includes a description of a case study that is based on our experiences working with pre-service teacher candidates, and special education and behavior analysis graduate students in K-12 and after-school instructional programs.

An Evaluation of Two Tact-Training Procedures on Acquired Tacts and Tacting During Play.

A common practice in tact training is to include a supplemental verbal stimulus (e.g., "What is it?") in addition to the presentation of a nonverbal discriminative stimulus. Previous literature has suggested that this supplemental verbal stimulus can impede acquisition and generalization relative to the presentation of the object alone, as it may establish faulty stimulus control or decrease spontaneous tacting. Research has yet to compare these 2 training methods on the generalization of learned tacts to more naturalistic, play-based environments. The present study evaluated the use of "What is it?" compared to the presentation of only the nonverbal discriminative stimulus on tact acquisition among 3 children with autism spectrum disorder and the extent to which these training procedures led to tacting in a play-based setting following discrete-trial training. Overall, participants learned to tact stimuli under both conditions, and all participants demonstrated generalization of tacts in a play-based setting. Recommendations for the development and evaluation of naturalistic posttraining assessment are discussed.

An Evaluation of a Game-Based Treatment Package on Intraverbals in Young Children with Autism.

The purpose of the current study was to evaluate a game-based treatment package on the acquisition of intraverbals in young children with autism. The treatment package was composed of using a listener response training game (i.e., bingo), providing verbal praise that contained the label for the listener response, and modeling a pretend play action related to the answer. During posttreatment probes, participants vocally answered wh- questions without any supplementary stimuli present and maintained responses during follow-up probes.

Intraverbal Training for Individuals with Autism: The Current Status of Multiple Control.

Teaching complex intraverbal responding to children with autism spectrum disorder (ASD) can be challenging and often requires careful programming. Divergent and convergent multiple control are particularly important elements to incorporate into intraverbal training programs, as well as procedures to ensure responding is under control of both discriminative and conditional vocal verbal stimuli. The current study systematically reviewed research articles on intraverbal training methods for individuals with ASD published and available from 2005 to 2016. The purpose of the review was to assess the extent to which divergent and convergent control was incorporated into training and to determine whether systematic instruction ensured correct verbal conditional discriminations. Thirty-six studies met inclusion criteria and were included in this reviewed. A total of 5 studies taught intraverbal responding under divergent control and 21 taught responding under convergent control. Two studies sufficiently described procedures to ensure accurate verbal conditional discriminations across trials. The results highlight the need for additional research on systematic teaching procedures for complex intraverbal repertoires.

Landmine-detection rats: an evaluation of reinforcement procedures under simulated operational conditions.

Because the location of landmines is initially unknown, it is impossible to arrange differential reinforcement for accurate detection of landmines by pouched rats working on actual minefields. Therefore, provision must be made for maintenance of accurate responses by an alternative reinforcement strategy. The present experiment evaluated a procedure in which a plastic bag containing 2,4,6-trinitrotoluene (TNT), the active ingredient in most landmines, was placed in contact with the ground in a disturbed area, then removed, to establish opportunities for reinforcement. Each of five rats continued to accurately detect landmines when extinction was arranged for landmine-detection responses and detections of TNT-contaminated locations were reinforced under a fixed-ratio 1 schedule. The results of this translational research study suggest that the TNT-contamination procedure is a viable option for arranging reinforcement opportunities for rats engaged in actual landmine-detection activities and the viability of this procedure is currently being evaluated on minefields in Angola and Mozambique.

Echoic and self-echoic responses in children.

Eleven typically developing children were assessed on the accuracy of prompted self-echoic responses following a 5-s delay from their initial echoic response, replicating procedures in Esch, Esch, McCart, and Petursdottir (2010) that compared discrepancies between echoic and self-echoic scores of autistic and typically developing children following a 2-s delay. We compared the two studies in terms of age, level tested, and echoic/self-echoic discrepancy scores. Age and test level differences were found to be statistically significant. Results are discussed in terms of discrepant self-echoic performance and self-echoic rehearsal as it relates to participant age, test level, motivating variables, and the development of complex behavior.
