Short breakdowns of the specific misconceptions that trip up well-prepared BCBA candidates — and how to catch yourself before you fall for them on exam day.
A bigger count doesn't always mean more responding. Here's how count, rate, and frequency differ, why the denominator is a clinical decision, and how to read the word frequency on the BCBA exam.
Three discontinuous measurement procedures can all give you a percentage, but the scoring rule decides what that percentage means. Here's how to choose a procedure and interpret each result for the BCBA exam.
Two observers can agree perfectly and both be wrong. Here's how to tell believability, validity, accuracy, reliability, and IOA apart, and why high IOA never proves your data are accurate or valid.
A low standardized score tells you what was observed — not why it happened or what to treat. Here's how to separate observation, interpretation, and decision, and why every tempting wrong answer skips a step.
Burst, variability, resurgence, spontaneous recovery — all four can follow extinction, and they're not the same thing. Here's how to reconstruct the contingency history instead of reaching for the first familiar word.
Every option is real, defensible, and backed by evidence — and three of them are still wrong. Here's how to weigh function, safety, history, and feasibility at once instead of freezing.
Every option in this classic trap describes a real ABA procedure. Only one actually matches the function the assessment confirmed — and catching the difference is the whole skill being tested.
Radical and methodological behaviorism both accept that private events are real. That's exactly what makes them so easy to confuse — and why one careful-sounding requirement gives the wrong answer away.
You've probably missed this question before — not because you didn't know the four scientific goals, but because your brain reached for the answer that sounded more sophisticated instead of the one the evidence actually supported.
