When selecting an additional behaviour, it is important to review the criteria discussed earlier:
- Objectivity, clarity, completeness
- Are the behaviours sufficiently independent?
If you expect that intervention target the first behaviour will indirectly target the second behaviour, you will need to identify a different second behaviour.
In the case of Jonathan, we could select a word that typically develops at around the same age, is used in the same context, but which serves a different communicative function (e.g., ‘up’).
Activity
Return to the second target behaviour you identified in the previous exercise.
- Does it meet the requirements of objectivity, clarity, and completeness?
- Is it sufficiently related, but independent of, the first target behaviour?
Now, on the graph, draw some data points to illustrate what you think your results would look like if you were to target both target behaviours.
