ABSTRACT
Errorless learning is an instructional strategy used widely with individuals with intellectual and developmental disabilities. The present systematic review aims to update the literature on the application of 'within-stimulus' errorless procedures. The protocol was registered with PROSPERO (CRD42018118385). Twenty-eight articles including 283 participants met the operationally defined inclusion criteria. In the majority of cases, the errorless learning procedures evaluated led to improvements in acquiring discrimination skills. Most of the reviewed studies evaluated stimulus fading. Results are discussed in relation to the selection of within-stimulus procedures. Areas identified for future research include further evaluations of other within-stimulus tactics, as well as further refinement of procedural parameters.

The components of discrete-trial teaching (DTT) may be individualized to each learner during instruction (e.g., the type of prompts used). However, there is limited research on the relative efficiency and effectiveness of these different prompt types. In addition, the learner's preference for how they are taught is not always considered. The present study compared relative effectiveness of three prompt types (i.e., a gesture, modeling, physical guidance) to a no-prompt control condition during a receptive identification task with three boys with autism. One participant met the mastery criterion first in the model prompt condition, and two participants in the physical prompt condition. All participants selected the physical prompt during a concurrent-chains preference assessment. In addition, all participants completed a chained task using the most effective prompt type.

Response interruption and redirection (RIRD) is an effective intervention for decreasing stereotypy. During RIRD, contingent on occurrences of stereotypy, therapists interrupt the behavior and prompt the participant to complete an alternative response. Although RIRD has been implemented by teachers in classrooms, it requires continuous monitoring of participants to be implemented with fidelity and may be difficult for teachers to manage. The present study evaluated the effectiveness of RIRD when implemented in classrooms. In addition, we evaluated if novice teaching assistants could be trained to implement RIRD. Finally, a descriptive analysis of treatment integrity errors during RIRD was conducted. Three children and teaching assistants participated. Following a written instructions baseline, the teaching assistants were trained to implement RIRD using modeling, rehearsal, and feedback. The training increased the accuracy of RIRD implementation for all participants. Incorrectly initiating and terminating RIRD were the most common treatment integrity errors observed.

Picture activity schedules consist of a sequence of images representing the order of tasks for a person to complete. Although, picture activity schedules have traditionally been presented in a book format, recently picture activity schedules have been evaluated on technological devices such as an iPod™ touch. The present study compared the efficiency of picture activity schedule acquisition on book- and tablet-based modalities. In addition, participant preference for each modality was assessed. Three boys aged below 5 years with a diagnosis of autism participated. Participants were taught to follow the schedules using both modalities. Following mastery of each modality of picture activity schedule, a concurrent-chains preference assessment was conducted to evaluate participant preference for each modality. Differences in acquisition rates across the two modalities were marginal. Preference for book- or tablet-based schedules was idiosyncratic across participants.

Response redirection and response blocking reduce stereotypy maintained by automatic reinforcement. The current study evaluated the effects of redirection and response blocking on the stereotypic responding of three elementary-age children diagnosed with autism. During the treatment evaluation, redirection and response blocking were evaluated using an alternating treatment embedded in a reversal design. Both procedures resulted in comparably low levels of motor stereotypy. Following treatment evaluation, a concurrent chain was conducted to evaluate participant preference for redirection or response blocking. All three participants preferred redirection. Practitioners may wish to consider participant preference when developing and implementing treatments for stereotypy.
