Chapter 3: Graphing Behaviour and Measuring Change Graph: visual representation of occurrence of behaviour over time 6 components are necessary for a graph to be complete: 1. Y-axis and x-axis. On most graphs, x-axis usually one or two times longer than y-axis 2. Labels for y-axis and x-axis. Y- behaviour and dimension of behaviour. X- unit of time during which behaviour is recorded 3. Numbers on y-axis and x-axis. Y- numbers indicate units of measurement of behaviour. X- numbers indicate units of measurement of time. There should be hash mark 4. Data points 5. Phase lines: vertical line on graph that indicates change in treatment 6. Phase labels. Baseline is label most often given to no-treatment phase Research designs Research designs: determine whether treatment (independent variable) was responsible for observed change in target behaviour (dependent variable) and to rule out possibility that extraneous variables caused the behaviour to change Functional relationship (between procedure and target behaviour): when researcher shows that behaviour modification procedure causes a target behaviour to change A-B design o Simplest type of design used in behaviour modification. A=baseline, B= treatment o Does not rule out other causes, rarely used in behaviour modification o More interested in demonstrating change in behaviour than proving behaviour mod. Change the behaviour A-B-A-B reversal design o Extension of simple A-B design o Baseline and
