PSYB45H3 Chapter 3: Chapter 3 Notes
Document Summary
Chapter 3 graphing behavior and measuring change: graph is a visual representation of the occurrence of a behavior over time, behavior analysts use graphs to identify the level of behavior before treatment and after treatment begins. They can then document changes in the behavior during treatment and make decisions about the continued use of the treatment. The change can be from a no-treatment phase to a treatment phase, from treatment phase to no treatment phase or from one treatment phase to another treatment. Data points are not connected across phase lines: each phase in a graph must be labeled. Most behavior modification graphs have at least two phases that are labeled: the no treatment phase (baseline) and treatment phase. A-b-a-b reversal design: baseline and treatment phases are implemented twice. It is called a reversal design because after the first treatment phase, the researcher removes the treatment and reverses back to baseline.
