BCBA Exam Prep

Temporal extent is a key dimension of behavior in ABA. Learn its definition, how to measure it, and avoid common exam traps with this comprehensive guide.

Understand point to point correspondence in ABA: definition, examples, and how it differs from formal similarity. Essential for BCBA exam prep.

PLA Check (Planned Activity Check) is a group measurement procedure in ABA that uses momentary time sampling to estimate the proportion of individuals engaged in a target behavior at a given moment. This guide explains the procedure, provides examples, and discusses practical applications and limitations.

Master temporal locus in ABA: learn the difference between latency and interresponse time, how to measure them, and why they are key for behavior analysis and the BCBA exam.

Understand the controlling stimulus in ABA with clear definitions, practical examples, and study tips for the BCBA exam.

Multiple Stimulus With Replacement: How Scoring Works is written for BCBA candidates who need to apply multiple stimulus with replacement (MSWR) preference assessment to realistic ABA scenarios rather than memorize an isolated definition. The central question is always functional: what happened before the response, what happened immediately after it, and what pattern should be measured

Understand discontinuous measurement in ABA: how behaviors are recorded as occurring or not in intervals, with examples and study tips.

If you are asking what is the difference between shaping and chaining in ABA, begin with the response problem. Shaping changes a single response by differentially reinforcing successive approximations toward a target. Chaining teaches a response sequence by linking component behaviors that form a complex skill. Both procedures use reinforcement, but they solve different programming
