This document is a comprehensive study guide for ABA 503 – Exam 2, containing 70 carefully curated questions and correct answers based on the 2025/2026 curriculum. Structured in a clear Q&A format, it is designed to help university-level students grasp both fundamental and applied concepts of Applied Behavior Analysis (ABA). This resource is particularly valuable for those in psychology, education, special education, behavioral science, or BCBA certification programs.
Key topics include:
Laws of behavior such as the Law of Threshold, Law of Intensity-Magnitude, and Law of Latency
Reinforcement (definitions, process, examples, and relativity)
Motivating operations (MO) including Establishing and Abolishing Operations
Application of the Premack Principle
Differences between positive and negative reinforcement
Discriminative stimuli (SD and S-Delta) and their functional roles
Extinction as both a process and an operation, including its side effects (e.g., extinction burst, emotional responses)
Detailed breakdown of reinforcement schedules: continuous, intermittent, fixed/variable ratio, and fixed/variable interval
Nuanced discussion on punishment, including eliciting and discriminative effects
Clear explanations of escape and avoidance as negative reinforcement strategies
Each answer is correct and aligned with the latest academic standards, making this guide ideal for:
Students enrolled in ABA courses at universities
BCBA/RBT exam candidates
Educators and therapists-in-training reviewing behavioral intervention strategies
Anyone preparing for midterms, finals, or behavior-analytic certification exams
With straightforward definitions, real-life examples, and precise terminology, this guide is an essential resource for mastering core ABA concepts and applying them in both academic and practical settings.

Questions with 100% Correct Answers |
Latest Update
Stimulus intensity which no response is elicited and above which a
response always occurs. Elicits a response 50% of the time. "Uncertainty
point" - 🧠 ANSWER ✔✔Law of the Threshold
As the intensity of the US increases, the magnitude of the UR increases. - 🧠
ANSWER ✔✔Law of Intensity- Magnitude
As the intensity of the US increases, the latency to the appearance of the
elicited UR decreases. - 🧠 ANSWER ✔✔Law of Latency
(As an operation) The delivery of consequences when a response occurs. -
🧠 ANSWER ✔✔Reinforcement
, (As a process) The increase in responding that results from the
reinforcement. - 🧠 ANSWER ✔✔Reinforcement
Reinforcement isn't same from behavior to behavior or person to person. -
🧠 ANSWER ✔✔Important Note About Reinforcement
Momentary (Doesn't last forever). Always has two effects: Value Altering
Effect and Behavior Altering Effect. - 🧠 ANSWER ✔✔Motivation Operations
Establishing Operations (EO) and Abolishing Operations (AO) - 🧠 ANSWER
✔✔What are two types of MO's?
You are extremely hungry, and haven't had a steak in weeks, maybe
months. The steak becomes an EO and increases the value of the steak
and the current level of behavior. As you eat the steak, the stimuli becomes
an AO and the value and current level of behavior decreases. - 🧠 ANSWER
✔✔Example of EO to AO
1. Reinforcers are context specific. (MO, EO, AO)
2. Reinforcers cannot be defined independently of responses. (Premack
Principle) - 🧠 ANSWER ✔✔How is reinforcement relative?
