Which statement describes the antecedent in the ABCs of behavior?

• A. The environment
• B. The antecedent (the prompt that occurs right before the behavior)
• C. The behavior itself
• D. The consequence after

Answer: (B)

In the ABCs of behavior, the antecedent is the event or cue that happens immediately before the behavior and signals it to occur. It includes prompts, instructions, or cues in the environment that trigger the response. Saying the prompt that occurs right before the behavior captures this precisely. The environment is broader and can influence many antecedents, but the antecedent is the specific immediate cue that precedes the behavior. The behavior is the observable action, and the consequence after is what strengthens or weakens that behavior in the future. For example, a teacher’s instruction to raise a hand acts as the antecedent; the student’s hand raise is the behavior; the teacher’s attention afterward is the consequence.
