write an statement an open ended that start with isn'nt intriguing about: Behavior modification has been a handy and effective tool to address problem behaviors of those individuals with intellectual disabilities or autism. Why is it necessary to conduct a functional assessment of an issue behavior and assign powerful punishers to these issue behaviors? Functional behavioral assessment is the process of gathering information by a behavior analyst that can be used to maximize the effectiveness of a behavioral support plan. In other words, we identify treatments that work and can be implemented to modify these problem behaviors. By recognizing the function of the behavior, the unique history of the individual, and all the other factors that lead to these behaviors, we can program powerful reinforcers and punishers that are effective in achieving the overall outcome of the treatment. there are many reasons why behavioral analysts cannot rely on just functional assessment to find the most effective interventions. One of the first obstacles is that the analyst should start with the least restrictive approach by first conducting a closed-ended indirect assessment. This is a notoriously unreliable step as members of the family usually yield different behavioral functions. In addition, behavioral analysts should ask questions that allow caregivers and teachers to provide the full scenarios of problem behaviors, their antecedents, and consequences from their previous experiences
