Dual-Task Input and Decision Training: Practice Thinking During Fast Input
The app compares speed and accuracy during input alone with performance when input and decisions are combined.
Dual-Task Input and Decision Training
The app measures input speed and decision accuracy separately, then compares them with performance when both tasks are combined.
Open the app →When a user speeds up number-key and mouse input while judging a new visual situation, choosing the next action can become harder. Hand speed alone does not explain this problem. The user selects an input sequence while also judging the situation. When those choices overlap, selecting the next action can take longer. This app does not score input speed alone. It also measures the decision performance that remains during input.
The app measures input and decisions separately, then together
The 10-minute session first measures an input baseline and a decision baseline. The player then performs both tasks together. Later phases change the priority task and the decision rule, and a red STOP target checks whether the player can withhold an input. The final phase changes the input sequence and the questions to measure whether the player can apply the rules under unseen conditions.
The app counts a completed action only when the user presses the correct number key, presses the command key, and then clicks the target. Repeated keys and incorrect inputs do not count as completed actions. The user must maintain accurate input and accurate decisions together. A high APM number alone cannot raise the score.
The app reports three results separately
- Input speed retention compares combined-task speed with the input baseline.
- Decision performance retention compares accuracy and response time with the decision baseline.
- Unseen-condition decision accuracy is the percentage of new decision questions answered correctly.
The app shortens the target interval only after input and decision accuracy both meet their thresholds. If the player leaves the training view, the app pauses the training clock. The browser stores training records only on the current device.
The app applies research findings but does not guarantee better performance in a specific task
The app draws on research about response delays during combined tasks and the effects of repeated practice. It also adjusts difficulty to the player and measures performance again with problems that differ from the practice set.
Researchers have not tested whether this app improves performance in a specific game or job. Users should separately inspect their real task for fewer missed actions and shorter delays. This app does not diagnose or treat health conditions, intelligence, or ADHD symptoms.
