Behavior Modification Single Subject Research Design
Single Subject (small n) Problems with group analysis Individual differences are ignored These are important factors! This logic is based on farming analysis! The logic of single subject is high levels of internal validity (control) then replication. Systematic, Direct
Experimental Single Subject Design Using a subject as their own control If we establish a pattern of responding and then change that pattern of responding at the exact moment the IV is present we conclude that it was the IV that had the effect
Multiple Baseline Several individuals Baselines overlap to control for environmental variables. The treatment is then introduced at different times for each If the behavior changes in each person at the treatment time, then the IV has the effect.
