PSYB45H3 Chapter 3: Chapter 3
Document Summary
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: y-axis and x-axis. On most graphs, x-axis usually one or two times longer than y-axis: labels for y-axis and x-axis. X- unit of time during which behaviour is recorded: 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: data points, phase lines: vertical line on graph that indicates change in treatment, phase labels. Baseline is label most often given to no-treatment phase. A=baseline, b= treatment: does not rule out other causes, rarely used in behaviour modification, more interested in demonstrating change in behaviour than proving behaviour mod. Interested in same target behaviour exhibited by multiple subjects. have targeted more than one behaviour of same subject.
