What does Mr. Peterson want to identify through his observations of Arnold's behaviors?

Mr. Peterson’s focus on identifying triggers associated with specific activities is crucial for understanding Arnold's behavior. By observing these behaviors, Mr. Peterson can pinpoint particular situations or events that lead to specific reactions from Arnold. This knowledge allows him to modify the environment or structure activities in a way that either minimizes negative behaviors or encourages positive ones. Understanding triggers helps in developing targeted interventions and support systems tailored to Arnold's needs, which is essential in special education settings.

Other options, while relevant to behavior management, do not align as directly with the goal of observing behaviors to understand the direct influences on Arnold’s actions. Reinforcement strategies may be helpful, but without first identifying triggers, it's challenging to know what to reinforce. Similarly, general classroom management techniques and peer influences are broader concepts that may not specifically address Arnold’s unique behavioral patterns in the context of his individual experiences.
