help me create a response for this discussion post: Two things I learned about FAs

1. Starting with assessments shorter in length and gradually increasing the duration

2. Limiting the response classes to one or a few behavior topographies (Hanley et al. 2003)

A variation in a Functional Analysis, brief functional analysis, is where each condition is only run 1-2 times versus multiple times, as in a full FA.

Question: If you have assisted with an FA, what struggles did you encounter when conducting them? If you have not done one, then what do you think will be a common challenge or limitation in implementing FAs?

keep the response short within 5-6 setences, graduate student like but also simple
