RESUMEN
Matrix training consists of arranging targets for instruction to promote fine-grained stimulus control resulting in the establishment of skills without direct training. Recent reviews of the matrix training literature (Curiel et al., 2020a, b.; Kemmerer et al., 2021) highlighted the efficacy and efficiency of the approach with learners with and without disabilities. These reviews noted substantial variations in procedures across studies, suggesting the approach may be flexibly deployed across content areas and teaching procedures. This outcome is positive for practitioners as they may customize matrix training to meet the unique needs of their clients. However, it also necessitates decision making to sort through the variations in the literature. This tutorial was developed to help practitioners weigh various considerations when using matrix training. Tools and resources are provided to illustrate and accelerate adoption into practice settings.

RESUMEN
A graphic organizer (GO) is a note-taking device with concepts and fill-in spaces that may enhance equivalence yields under suboptimal training and testing parameters (e.g., linear training, simultaneous testing, five-member all-abstract classes). We used a nonconcurrent multiple-probe design across eight adult participants to evaluate the effects of a treatment package consisting of abstract matching-to-sample baseline relations training (MTS-BRT) and GO-construction training. GOs were faded until participants drew or wrote the trained relations from a blank page, which was available in the pre- and posttests. There was a 75% yield (six of eight participants) on the first posttest and a 100% yield following remedial training with Set 1. With Set 2, MTS-BRT alone resulted in voluntary GO construction and a 75% yield (three of four participants) on the first posttest and a 100% yield following remedial training. These results suggest that teaching participants to draw relations among stimuli may strengthen the effects of MTS-BRT training on equivalence yields.

Problem-solving strategies, such as visual imagining and self-questioning, may assist children with autism spectrum disorder (ASD) in recalling past events. In the current study, at the start of each session, a 7-year-old boy with ASD engaged in a novel activity with a behavior therapist who took pictures of the activity. Ninety minutes later, a different therapist asked the participant to describe the prior activity. The intervention consisted of showing the participant pictures of the activity, telling him to close his eyes and imagine the activity, modeling asking and answering seven questions (e.g., "Who was there?" "What was one thing that happened?"), prompt fading, and reinforcement. Following the intervention, recall statements increased.
RESUMEN
Many individuals with developmental disabilities exhibit noncompliance during intensive instruction. As a treatment for noncompliance, the high-probability instructional sequence (high-p sequence) consists of delivering several high-p instructions before a low-p instruction. The purpose of this study was to extend the research on comparing consequences for high-p demands-namely, praise, edibles, and videos-with an 11-year-old girl diagnosed with CHARGE syndrome. CHARGE syndrome is a rare medical condition often resulting in multisensory impairments and developmental delays. In Treatment Analysis 1, we compared praise versus edibles as consequences for compliance with high- and low-p instructions. Results showed the edibles were initially more effective than praise, but the effects did not maintain. In Treatment Analysis 2, we changed the consequence for compliance with high- and low-p instructions to a music video and then attempted to fade the number of high-p instructions. We replicated the efficacy of the high-p sequence but failed to fade the number of high-p instructions and failed to achieve maintenance. Therefore, in Treatment Analysis 3, we conducted presession preference assessments of music videos in order to use a selected video as the consequence for compliance. This "varied reinforcement" intervention resulted in high levels of compliance. Results are discussed in terms of motivating operations and recommendations for practice.
RESUMEN
An important communication skill for children with autism is answering multiple questions about visual stimuli (e.g., "What is it?" "What color is it?"). We targeted answering "What number?" and "What shape?" in the presence of numbers inside shapes, and "What is it?" and "What color?" in the presence of colored objects (e.g., a yellow cat) with 3 preschoolers with autism. In addition to a progressive time delay, we required the participants to answer the questions by echoing a keyword from the questions. For example, we taught them to answer, "What color?" with "color blue." In the context of a multiple-probe design across behaviors within a multiple-probe design across participants, the procedure was effective in increasing trained responses and producing within- and across-category generalization. The echoic may have facilitated the responses by increasing the salience of the auditory stimuli and strengthening intraverbals within autoclitic frames.

We reviewed 12 studies in which the researcher taught problem-solving strategies, such as self-questioning and visual imagining, to children and adolescents with and without disabilities to facilitate the learning of math, spelling, play/social, and communication skills. We analyzed these studies in terms of types of problem-solving strategies, the multiple control involved in problem solving, the extent to which problem solving occurred at the overt or covert level. In addition to suggesting limitations of the literature, we recommend areas for future research and practice.
RESUMEN
Matrix training is a generative approach to instruction in which words are arranged in a matrix so that some multiword phrases are taught and others emerge without direct teaching. We taught 4 preschoolers with autism to follow instructions to perform action-picture combinations (e.g., circle the pepper, underline the deer). Each matrix contained 6 actions on 1 axis and 6 pictures on the other axis. We used most-to-least prompting to train the instructions along the diagonal of each matrix and probed the untrained combinations. For 2 participants, untrained responding emerged after the minimum amount of training. The other 2 participants required further training before untrained combinations emerged. At the end of the study, 3 of the 4 participants performed the trained actions with previously known pictures, letters, and numbers. This study demonstrated that matrix training is an efficient approach to teaching language and literacy skills to children with autism.

Conditional discrimination is inherent in the intraverbal relation when one verbal stimulus alters the evocative effect of another verbal stimulus and they collectively evoke an intraverbal response. Rarely in research on conditional discriminations have both conditional and discriminative stimuli been vocal verbal and rarely have the responses been topography-based. Making conditional discriminations in intraverbal behavior is a repertoire that is often delayed in children with autism and other developmental disabilities. Reviewed in this paper is research on teaching intraverbal behavior, auditory conditional discriminations, and restricted stimulus control. The purpose of these reviews is to identify the extent to which previous researchers examined conditional discriminations in the intraverbal relation and to recommend directions for research in this area.
