Document Summary
Chemistry- process of electrolysis in water can be observed in any body of water; results will be the exact same. Principles of single-case experimental designs: baseline during phase a (before treatment onset) and the level of scores or observations during phase b after treatment onset) Measurement of pre-experimental behavior (before introduction of iv) Examine baseline performance and contrast with performance after intervention. The critical comparison is between the level of symptom scores reported or observed. Actively rather than passively manipulated; only 1 variable is changed at a time to document experimental control. Can behavior therapy help alleviate problem behaviors associated with fragile x, a rare and biologically determined syndrome? (no studies have examined this before) N=1, so this is critical for comparing the different conditions. Get a clear picture of what the dv looks like before the presence of the iv. B= posttest; measurement after intervention (presence of iv) A (baseline) b (posttest) a (removal of iv)
