Correct Answer:
C. A trigger that occurs before a behavior
Explanation:
The correct answer is A trigger that occurs before a behavior because the word 'antecedent' literally means something that exists or happens before another event.
- Step 1 (Definition): In behavior modification (specifically the ABC model: Antecedent-Behavior-Consequence), an antecedent is any environmental cue, prompt, or signal that sets the stage for a behavior to occur.
- Step 2 (Application): Examples include a teacher turning off the classroom lights (antecedent) signaling students to become quiet (behavior), or a school bell ringing to prompt class transitions.
- Incorrect Options:
- A reward given after a behavior is incorrect because rewards are positive consequences that follow a behavior to increase its recurrence.
- A consequence following a behavior is incorrect because consequences strictly occur after the action, whereas antecedents precede it.
- A punishment for misbehavior is incorrect because punishment is a negative consequence designed to weaken an already completed action.
