In a single-subject design, what is the process of predicting a variable, verifying it, and replicating the results called?

• A. Baseline Logic
• B. Baseline
• C. Behavior
• D. Behavior Checklist

Answer: (A)

Baseline Logic is the reasoning that underpins single-subject designs by using data to predict what would happen without an intervention, then verifying that prediction through systematic observation, and finally replicating the results to show a consistent relation between the intervention and the behavior. This triad—predicting the baseline trajectory, confirming it holds under controlled changes, and reproducing the effect across conditions or occasions—allows us to infer a functional relation between treatment and behavior. The other options don’t capture this analytical sequence: a Baseline is just the initial data collection phase, without the explicit predictive-verification-replication reasoning; Behavior refers to the target behavior itself; a Behavior Checklist is a measurement tool, not the analytic process.
