What does the method of expanded trials involve in terms of target presentations?

The method of expanded trials primarily focuses on gradually increasing the time interval between the presentations of a target behavior or stimulus. This approach is designed to help learners retain the information and to promote generalization of the skills being taught. By allowing more time between each presentation or trial, the method encourages learners to process, respond, and ultimately master the target behavior over time, rather than becoming overwhelmed by frequent and immediate repetitions.

Increasing the duration between trials can help reinforce learning, making it less likely for the learner to rely on rote memorization and more likely to engage with the learning material on a deeper level. This method prioritizes building a strong understanding and retention of information, which is critical in educational settings for individuals on the autism spectrum.
