Simulated participant view
A spatial planning task where participants navigate a player token to a target on a small grid using the fewest moves.
No data is recorded
A 4×4 grid is shown with a blue player, a green target, and optional wall obstacles. Arrow buttons move the player one step at a time.
Useful when the study needs a planning or problem-solving measure that is visual and interactive but does not require language. Good complement to matrix reasoning or trail-making.
Less suitable for very high-frequency EMA because each trial requires deliberate multi-step input. Motor coordination issues can confound performance.
Start with 0–2 wall obstacles for practice, then use 2–3 walls in live trials. Keep the move limit generous enough that participants who plan poorly still finish most levels.
Extra steps over the BFS-optimal path is the primary planning efficiency metric. Lower extra-step counts indicate more effective advance planning.
