Document Summary
Baseline logic & steady state strategy: baseline logic, three elements, prediction, verification, replication, steady state strategy, repeated exposing a subject to a condition for the purposes of eliminating extraneous influences before introducing the next condition. In the reversal design, the independent variable is presented to one dependent variable at one time, and later to a different, incompatible dependent variable. Aba, bab, abab: aba design, minimal requirement for demonstrating experimental control, seldom used, lacks the final element of replication, bab design. Limits of reversal designs: stability, all data should be stable before condition change, trending should be monitored, why, replicability of procedure and effect, each procedure needs to be repeated with similar effects. Irreversibility: some effects cannot be withdrawn, cannot reproduce past levels, social concerns, participants do not want treatment withdrawn, educational concerns, time lost, loss progress, ethical concerns, safety. It is the most versatile, can be used across behaviours, participants, or settings. Applications across different behaviours of the same participant.
