🟢 FITLIGHT® Go/No-Go Task Instructions

🎯 Goal

Test and improve reaction time and inhibitory control - the user responds to Go lights and must inhibit response to No-Go lights.

✅ 1. Define Stimuli

• Go Light = Green

• No-Go Light = Red

• Optional: Add Blue as a distractor (no response)

🧠 You can reverse colors for difficulty or change them mid-task. 

✅ 2. Configuration in the FITLIGHT® App

1. Open the FITLIGHT® App

2. Go to Create New> New Advanced

3. For each light set the parameters, such as sensor (how light is deactivated), timeout (time each light is on), etc. The most important settings will be:

• Colors (e.g., Green = Hit, Red = Don’t Hit)

• Result (Success for Go Light, Fail for No-Go Light)

✅ 3. Task Instructions

Hit ONLY the green lights as fast as you can. If a red light appears, DO NOT touch it. Stay ready and respond quickly.

✅ 4. Run the Task

• Start the task from the app.
  

• User responds by touching the lights when they meet the Go condition.

• The system will automatically log: 

  • Correct Hits (Go)

  • False Alarms (No-Go)

  • Reaction Time

✅ 5. Post-Task Analysis

Download or review results:

• Reaction Time averages

• Accuracy %

• Commission Errors (hit red)

• Omission Errors (missed green)

🔄 Variations for Progression

• Add movement tasks (shuffles, squats between hits)

• Decrease light timeout (users have less time for information processing)

• Add a dual task (e.g., solve a math problem while reacting)

• Use sound cues (Go = beep, No-Go = buzz)
