Final answer:
Bobby's behavior of looking at the RBT when given a scenario displays a listener skill, which involves responding to another's verbal behavior appropriately.
Step-by-step explanation:
In the given scenario where Bobby looks at the RBT, the behavior demonstrated can be considered a listener skill. Listener responding, or listener skills, in the context of applied behavior analysis (ABA), refers to a person's ability to respond appropriately to another's verbal behavior. For instance, when an instructor asks a student to point to an object and the student complies by looking or pointing at the object, they are demonstrating listener skills. This skill is crucial for social interaction and following instructions and is different from intraverbal skills, where a person responds conversationally to another's language (without any visual prompts), and tact, which is labeling or commenting about an object or event after direct contact with it.
