Basics of Graphing
What is a graph in behaviour modification?
A visual representation of behaviour occurrences over time.
Name the six components of a behaviour modification graph.
Axes, labels, axis numbers, data points, phase lines, phase labels.
What are the four dimensions of behaviour that can be graphed?
Frequency, duration, latency, intensity.
What three features are examined to evaluate behaviour change?
Level, trend, variability.
Why do we use graphs in behaviour modification?
To monitor progress and determine treatment effectiveness.
Why are graphs important in behaviour management?
They show changes before and after treatment and help establish functional relationships.
What is a phase line?
A vertical line indicating a change in treatmen
What does frequency measure?
How many times a behaviour occurs.
What does level indicate?
How high or low data points are on the y-axis.
What is baseline data?
Data collected before treatment begins.
What two elements do graphs illustrate?
Time and level of behaviour.
What are phase labels?
Labels for phases like baseline and treatment.
What does duration measure?
How long the behaviour lasts.
What does trend indicate?
Whether behaviour is increasing, decreasing, or stable.
How do phase lines affect interpretation?
They separate treatment phases for comparison.
What does the x-axis represent?
Units of time (e.g., days, sessions).
Why are axis numbers important?
They show measurement units for behaviour and time.
What does latency measure?
Time from stimulus to behaviour onset.
What does variability indicate?
How far data points are from the mean in a phase.
What is the first step before graphing?
Collect behavioural data
What does the y-axis represent?
The behaviour and its dimension (e.g., frequency, duration).
What do data points indicate?
: The level of behaviour at a specific time.
What does intensity measure?
The force or magnitude of the behaviour.
Why is low variability desirable?
It shows consistent behaviour within a phase.
How can graphs inform treatment decisions?
By showing trends and changes in behaviour over time.
