Interactive computer training to teach discrete‐trial instruction to undergraduates and special educators in Brazil: A replication and extension

Discrete‐trial instruction (DTI) is a behavioral method of teaching young children with autism spectrum disorders (ASD) that has received a significant amount of research support. Because of a lack of qualified trainers in many areas of the world, researchers have recently begun to investigate alternative methods of training professionals to implement behavioral teaching procedures. One promising training method is interactive computer training, in which slides with recorded narration, video modeling, and embedded evaluation of content knowledge are used to teach a skill. In the present study, the effectiveness of interactive computer training developed by Pollard, Higbee, Akers, and Brodhead (2014), translated into Brazilian Portuguese, was evaluated with 4 university students (Study 1) and 4 special education teachers (Study 2). We evaluated the effectiveness of training on DTI skills during role‐plays with research assistants (Study 1) and during DTI sessions with young children with ASD (Studies 1 and 2) using a multiple baseline design. All participants acquired DTI skills after interactive computer training, although 5 of 8 participants required some form of feedback to reach proficiency. Responding generalized to untaught teaching programs for all participants. We evaluated maintenance with the teachers in Study 2, and DTI skills were maintained with 3 of 4 participants.     

Evaluation of a self-instruction package for conducting stimulus preference assessments

Research suggests that inexperienced individuals cannot accurately implement stimulus preference assessments given written instructions alone. Training that includes written instructions supplemented with feedback from a professional with expertise in conducting preference assessments has proven effective; unfortunately, expert-facilitated direct training may not be widely available. In the current study, we used multiple baseline designs to evaluate the efficacy of an antecedent-only self-instructional package to train staff members to implement two methods of stimulus preference assessments. Accuracy was low when participants had access to written instructions alone. When access to enhanced written instructions was provided (i.e., technical jargon was minimized; instructions included pictures, diagrams, and step-by-step examples), inexperienced staff accurately implemented the assessments. Results are discussed in terms of opportunities to disseminate behavior-analytic technologies through self-instruction and print resources.     

Comparing self‐directed methods for training staff to create graphs using Graphpad Prism

An important skill for behavior analysts is creating graphs that clearly convey outcomes and conform to publication conventions. GraphPad Prism is software designed for creating scientific graphs, but no prior research has empirically evaluated training graphing skills using Prism. Two effective training methods are enhanced written instructions (EWI) and video modeling with voiceover instructions (VMVO), but no single‐subject studies have compared the effects of these methods. In this study, we compared the efficacy and social validity of EWI and VMVO for training staff to create graphs using Prism. A single‐subject design was employed to compare the effects of the methods on the individual performance of 11 graduate students. EWI and VMVO were both found to be effective, and more participants chose to use EWI.     

Training staff to conduct a paired-stimulus preference assessment

Three staff members were trained to conduct stimulus preference assessments using a paired-stimulus format with 8 children with autism. Staff were trained to mastery level using brief instruction, a video model, and rehearsal with verbal feedback. Training took about 80 min per staff member. Results demonstrated that staff rapidly learned to correctly perform paired-stimulus preference assessments with children.     

Evaluation of an efficient method for training staff to implement stimulus preference assessments

We used a brief training procedure that incorporated feedback and role-play practice to train staff members to conduct stimulus preference assessments, and we used group-comparison methods to evaluate the effects of training. Staff members were trained to implement the multiple-stimulus-without-replacement assessment in a single session and the paired-stimulus method in another single session. In all 16 cases (2 assessments for 8 trainees), correct responding increased to over 80% accuracy; in 14 of those 16 cases, it increased to over 90% accuracy. Thus, training produced mastery-level performance in a single training session in almost all cases.     

A replication of the response‐restriction preference assessment

We replicated the response‐restriction (RR) preference assessment and compared results in terms of preference hierarchies to those from free‐operant and multiple stimulus without replacement (MSWO) formats with six children with autism spectrum disorders (ASDs). We also assessed social validity of each format with teachers and clinicians who work with children with ASDs. Complete hierarchies were produced in four of 18 assessments and with MSWO and RR formats only. Results of the social validity assessment varied across raters, with each preference assessment format receiving the highest rating from at least one rater. Results are discussed in terms of practical recommendations and relative to the preference assessment literature as a whole.     

Discrete‐trial training performance of behavior interventionists with autism spectrum disorder: A systematic replication and extension

Further research is needed on strategies to improve employment outcomes for individuals with autism spectrum disorder (ASD). We replicated and extended prior research by examining the acquisition, maintenance, and generalization of discrete‐trial training (DTT) performance of adults with ASD who were interested in careers as behavior technicians. Three participants received training on how to implement DTT with children and we assessed the maintenance and generalization of DTT performance in the absence of feedback. Results indicated that procedural integrity generalized across children and targets and maintained for 6 to 17 session days without feedback. Results have implications for the successful employment of individuals with ASD as behavior technicians and for future research on strategies to enhance their performance on the job.     

Web‐based stimulus preference assessment and reinforcer assessment for videos

This study replicated and extended the use of a web‐based multiple‐stimulus‐without‐replacement preference assessment (Curiel, Curiel, Li, Deochand, & Poling, 2018) by adding a web‐based single‐operant reinforcer assessment. Five adults diagnosed with autism spectrum disorder participated in this study. The web‐based program identified preference hierarchies for 4 of the 5 participants, and the single‐operant reinforcer assessment confirmed that the highly preferred videos functioned as reinforcers. Advantages of computer‐based stimulus preference and reinforcer assessments are discussed.     

The effects of video modeling with voiceover instruction on accurate implementation of discrete-trial instruction

The present study replicates and extends previous research on the use of video modeling (VM) with voiceover instruction to train staff to implement discrete-trial instruction (DTI). After staff trainees reached the mastery criterion when teaching an adult confederate with VM, they taught a child with a developmental disability using DTI. The results showed that the staff trainees' accurate implementation of DTI remained high, and both child participants acquired new skills. These findings provide additional support that VM may be an effective method to train staff members to conduct DTI.     

Assessing long‐term maintenance of staff performance following behavior skills training in a home‐based setting

We used a multiple baseline across participant design to evaluate the effects of behavior skills training on teaching three behavior therapists to implement discrete trial teaching (DTT) and evaluate the long‐term maintenance of skills acquired through behavioral skills training. For participants whose skills did not maintain, the authors evaluated an independent self‐evaluation procedure on their performance. Following DTT implementation training, maintenance probes were assessed at 2‐, 4‐, 6‐, and 8‐week follow‐ups. The results demonstrated that one participant maintained 100% procedural integrity (PI) through all follow‐ups, one participant decreased below mastery criterion at the 2‐week follow‐up, and one participant dropped below mastery criterion at the 4‐week follow‐up. Those participants that demonstrated decreased accuracy of implementation of DTT programs and were taught to implement a self‐evaluation procedure. Following self‐evaluation, PI maintained for up to 7 weeks for one participant. Our results suggest that if PI does not maintain, self‐evaluation may be a supplementary intervention to increase and maintain PI of new employees.     

Equivalence‐based instruction of academic skills: Application to adolescents with autism

This study evaluated the efficacy of three equivalence‐based instruction procedures on the acquisition of novel academic skills by 3 adolescents diagnosed with autism in a school setting. The skills targeted for instruction were related to topics in history, science, and mathematics, and were taught using different training structures from the PEAK‐E curriculum. All participants demonstrated mastery of the trained relations and the tested derived relations following all variants of equivalence‐based instruction.     

Effect of self‐construal and threat to self‐esteem on ingroup favouritism: Moderating effect of independent/interdependent self‐construal on use of ingroup favouritism for maintaining and enhancing self‐evaluation

The present study examined the hypothesis that in situations that threaten self‐esteem, people with independent self‐construal show more ingroup favouritism, whereas people with interdependent self‐construal do not. Using a minimal group paradigm, consistent with the hypothesis, the results showed that self‐construal and threats to self‐esteem have an interactive effect on ingroup favouritism. Individuals with independent self‐construal showed more ingroup favouritism when their self‐esteem was threatened than when it was not threatened, whereas individuals with interdependent self‐construal exhibited less ingroup favouritism when their self‐esteem was threatened than when it was not threatened. These findings suggest that independent/interdependent self‐construal moderates the use of ingroup favouritism for maintaining and enhancing self‐evaluation.     

Relation between self‐knowledge reference and self‐monitoring of emotional state1

Abstract: We used a task facilitation paradigm to examine whether self‐knowledge reference and self‐monitoring have a functional relationship. Eighteen participants performed a series of tasks: self‐knowledge reference, evaluation, self‐monitoring, and semantic. Responses on the self‐knowledge reference task were faster when the previous task was self‐monitoring rather than semantic. However, responses on the self‐monitoring task were similar regardless of whether it was preceded by the self‐knowledge reference task or the evaluation task. Our results suggest that self‐monitoring induces self‐knowledge reference.     

Modesty in self‐presentation: A comparison between the USA and Japan

Japanese participants in Study 1 exhibited a self‐effacing tendency when no reason for their self‐evaluation was provided. However, they exhibited a self‐enhancing tendency when they were offered a monetary reward for the correct evaluation. In Study 2, Americans, especially American men, exhibited a self‐enhancing tendency whereas Japanese exhibited a self‐effacing tendency when no reason for making the evaluation was presented. This cultural difference disappeared when participants were provided with a monetary reward for correctly evaluating their performance level. These results support the view that the modesty observed in self‐evaluation among Japanese participants is a ‘default strategy’ to avoid offending others.
