Document Summary

3: graphing behavior and mea uring change: a graph is a visual representation of the occurrence of a behavior over time. A phase is a period in which the same treatment (or no treatment) is in effect. Data points are not connected across phase lines. This allows you to see differences in the level of the behavior in different phases easily: phase levels- each phase in a graph must be labeled. Most behavior modification graphs have at least 2 phases that are labeled: the nontreatment phase and the treatment. phase. (cid:862)baseli(cid:374)e(cid:863) is the la(cid:271)el (cid:373)ost ofte(cid:374) gi(cid:448)e(cid:374) to the (cid:374)o-treatment phase. If the behavior changes each time the procedure is implemented and only when the procedure is implemented, a functional relationship is demonstrated. First it may not be ethical to remove the treatment in the second baseline if the behavior is dangerous. 2) you must be fairly certain that the level of the behavior will reverse when treatment is withdrawn.
