Questions Author’s Name The Institutional Affiliation Course Number and Name Instructor Name Assignment Due Date Components and A-B-C Mapping Smith (2001) breaks the discrete trial (DT) down into its constituent components, including discriminative stimulus or instruction, prompt, learner response, consequence, and intertrial interval. In the three-term contingency, the antecedent is the instruction and prompt; behavior is the emitted response; the consequence is reinforcement or error correction; and the intertrial interval is the time separating trials. For instance, the instructor delivers Touch nose, models it at the same time, and pauses. The learner touches the nose, earns a token and a short praise, and the trial is terminated with a pause before the next command. In case the learner made an error, explicit correction and re-presentation were immediately provided, maintaining unambiguous A–B–C relations. Categories of Skills Most Appropriate for Using DTI to Teach Smith (2001) mentioned that discrete trial instruction (DTI) is ideal in terms of initial acquisition and discrimination of new behaviour that involves the need for highly structured repetitive practice. Priority categories are receptive and expressive language, vocal and motor imitation, matching and simple perceptual discriminations, early academic readiness repertoires, and component steps of basic motor or self-help chains. Weinsztok et al. (2023) also second Smith’s (2001) study, and claim that DTI can also set up stimulus control and consolidate responses that are not inherently motivating, then switch to naturalistic teaching to encourage the development of generalization and spontaneity. Smith (2001) illustrates that such skills include single-step following directions, everyday objects, gross and fine motor imitation, matching to sample, early academic readiness, and component steps of self-help chains for which brief repeated trials accelerate teaching. 3 Advantages and Disadvantages of DTI Steege et al. (2007), DTI provides three advantages, including high density of tightly controlled learning opportunities; accurate control over antecedents and consequences that are manipulated; and rapid acquisition of initial discriminations and response forms prior to general programming. They also indicate three weaknesses when utilized independently: restricted generalization and diminished spontaneity across environments; insufficient coverage of broader cognitive, social, academic, leisure, and instrumental (functional living) contexts; and inability to reduce interfering behavior without supplementary, function-based strategies. Thus, DTI should be incorporated into teaching as part of a larger naturalistic, ABA-based program with explicit plans for generalization. 5 Different Ways ABA Programs are Supposed to Support Individuals with ASD Steege et al. (2007) emphasize they need to provide the instruction in all relevant area such cognitive, social, academic, leisure, ...
