 steady state strategy, the strategy that we use in single subject research to be able to make comparisons between pretest and pretest. Oh god, we don't use pretest in single subject research. Between baselines and independent variables, conditions and bs and a's and c's and all those letters that just pop into your head when you try to give a clean clear example and it doesn't work. Anyway, so steady state strategy, we wait for behaviors to behaviors. Oh, it's a good day. Behavior is to stabilize in one condition before we switch conditions and then we switch conditions to the, I don't know, maybe the b condition or in intervention conditions and we wait for the behavior to stabilize before we remove that condition or change that condition again to find out what effect that condition had on behavior, right? So without that stability, without that steady state responding, we're going to have a real hard time drawing conclusions from one condition to the next. So steady state strategy is the logic that we use to make the comparisons in our single subject research.
