Task parameters
Three conditions run in sequence: tracking only → rest → digit odd/even → rest → dual. Outputs: dual-task cost for tracking and classification.
This is a researcher preview. No participant data is recorded.

A divided-attention task measuring performance costs when a motor tracking task and a cognitive classification task are done simultaneously.
No data is recorded
Three successive conditions: tracking a drifting ball with arrow buttons, classifying digit parity (odd/even), and doing both simultaneously.
Useful when the study needs a measure of dual-task cost or attentional resource competition. Particularly relevant in ageing, fall risk, fatigue, and multitasking research.
Not suitable for high-frequency EMA because the three-condition structure makes each session nearly three minutes long. The task also has non-trivial onboarding demands.
Use the dual-task cost metrics (single minus dual performance) as the primary outcome rather than absolute performance levels. Ensure participants practice the single tasks individually before the dual condition.
Dual-task cost = single-task performance minus dual-task performance. Larger costs indicate poorer attentional resource allocation under load.
