Single subject experimental design: Reversal, Multiple Baseline, Multielement, changing criterion (ABA)

The video elaborates on single-subject experimental designs in ABA research. These designs focus on small groups or individual subjects, allowing comparison of behaviour to past behaviour by alternating between baseline (no treatment) and intervention phases to establish experimental control. It discusses various designs like the reversal/withdrawal design (A-B-A), multiple baseline designs, and multielement designs. Each has distinct advantages depending on research needs. These designs are crucial for systematically studying interventions’ effects on behaviour while considering ethical implications and potential confounding variables.
