What is the term for an antecedent intervention where the difficulty is initially presented at the lowest level?

The correct answer refers to the concept of stimulus fading in, which involves gradually increasing the difficulty or complexity of a task. In this approach, the antecedent intervention starts with tasks or demands that are easy or manageable for the individual. This method helps to build confidence and skill before moving to more challenging demands, ensuring that the learner is set up for success and reduces the likelihood of frustration or avoidance behavior.

Stimulus fading is particularly effective in teaching new skills, as it allows for a smoother transition to more complex tasks by initially presenting the difficulty at the lowest level. This gradual increase in difficulty can enhance motivation and promote positive learning experiences, which is essential in applied behavior analysis settings.

The other options do not capture the essence of this method. High-probability requests refer to making requests that the individual is likely to comply with before making a low-probability request, creating a different type of antecedent manipulation. Low-probability instruction involves presenting requests that the individual is less likely to comply with, which contrasts with the initial easy demands of stimulus fading. Preference assessments are techniques used to determine what individuals prefer, which is unrelated to the gradual introduction of task complexity.
