PSYB45H3 Lecture Notes - Abscissa And Ordinate
Document Summary
Chapter 3 graphing behaviour and measuring change. Graph: a visual representation of the occurrence of a behaviour over time. Using a graph allows them to document changes in behaviour during treatment and make decisions about the continued use of the treatment. Time is indicated on the horizontal axis (x-axis or the abscissa) and the behaviour is indicated on the vertical axis (y-axis or the ordinate). Phase lines: vertical line on a graph that indicates a change in treatment. The purpose of research designs is to determine whether the treatment (independent variable) was responsible for the observed change (dependent variable) and to rule out the possibility of a third variable causing the variable to change. Functional relationship: when it can be shown that a behaviour modification procedure causes a target to change, it shows that there is a relationship between the procedure and the target behaviour.
