Cognitive mapping
What it is
“A drawing exercise”: Users are asked to produce a visual representation of their mental models.
Why this method
- Exploratory and discovery-based round.
- Helpful for exploring research questions with ambiguous aspects that are tough to communicate verbally.
How to use
Checklist:
- A stack of blank paper and a black pen, two more pens in contrasting colours.
- A silent timer.
- Scripts: an encouraging intro
Time: at least one day (prepare, carry out and analyse the research), 6-10mins (per test)
Participants: 6 to 12
Steps:
- Give your participants the paper and pens and do the intro.
- The drawing exercise: Start a silent timer and keep quiet when they draw. After 2 minutes and again after 4 minutes, gently take the pen they’re using ang give them the next one. Mark the colour order, e.g., 1 black, 2 blue, 3 red. Tell them when they’ve got 20 seconds left.
- Ask the participants if they’d like to explain what they’ve drawn. Prompt for extra details when needed.
- Ask whether if they’d draw it differently if they did it again.
Tips & variations
- It’s fine if the participants spend slightly longer or shorter than 6 minutes.
- Don’t speculate: let everything be in their words if some of the drawing is skipped over during the explanation.
