# PSYB45H3 Chapter Notes - Chapter 3: Confounding, Abscissa And Ordinate, Reinforcement

## Document Summary

A graph: is the visual representation of the occurrence of a behaviour over time. The axis: y-axis (ordinate) and x-axis (abscissa) . Labels: y-axis tells you the behaviour that is being recorded (e. g hours of studying) while the x- axis tells you the unit of time in which the behaviour was recorded (e. g the days) Numbers: numbers on y-axis tells you the unit of measurement of the behaviour while the number of x-axis tells you the units of measurement of time. Data points: plotted on the graph and connected by a line. Phase lines: a vertical line on a graph that indicates a change in treatment, separates baseline (no treatment) from treatment and is usually dotes line. Note that: data points are not connected across phase lines. Phase labels: baseline and treatment label (e. g behavioural contract to increase studying ), and the least number of phase labels is 2. Simplest design, has only two phases: a-baseline and b-treatment.
