I obtained a baseline level of John's cooking behavior of 25% of the meals without praise. I then highly praised his cooking behavior, and it increased to 85% of the meals. Later, I stopped praising his cooking, and his behavior began to drop back to its baseline level. What sort of design was I using?
A) Multiple Baseline
B) ABA
C) Alternating-treatments
D) Reversal Replication

The design being used is an ABA design because the baseline behavior was established, an intervention (praise) was implemented and behavior was measured again, and then the intervention was removed and behavior was measured again to observe if behavior returned to baseline levels. The ABA design is also known as a withdrawal or reversal design. The other options (multiple baseline, alternating-treatments, and reversal replication) involve different types of experimental designs or interventions.
