What are the two types of DTT?

Discrete Trial Training (DTT) is a structured method used in applied behavior analysis to teach skills through a series of clear, repeated opportunities for a learner to respond. The correct answer identifies the two types of trials commonly used in DTT: mass trials and random rotations.

Mass trials involve presenting the same instruction or prompt repeatedly to the learner in a consistent format. This method allows learners to practice and reinforce a particular skill without the distraction of varying tasks or prompts. It helps refine the learner's response and increases fluency with the skill being taught.

In contrast, random rotations involve varying the tasks or prompting techniques presented to the learner. This approach helps to promote generalization of the learned skills across different contexts and stimuli, making it possible for learners to apply their skills more flexibly in real-world situations.

Understanding these two types of trials is crucial in applying DTT effectively, as they cater to different learning needs and can be strategically employed based on the specific goals of the instructional session.
