This guide covers the full lifecycle of running a study on NeuroFusion — from planning through participant operations and data export.

1. Plan Your Study Design

Before creating anything on the platform, outline:
  • Research questions — what are you investigating?
  • Data types — prompts (surveys), experiments (tasks), brain recordings, health metrics?
  • Participant pool — direct recruitment, Prolific, or in-lab?
  • Duration — single-session experiment, daily prompts for weeks/months, or both?
  • Eligibility criteria — do you need to screen participants? (age, consent, demographics)

2. Create an Organization and Invite Collaborators

  1. Create an organization for your study
  2. Invite co-investigators and research assistants as members
  3. Assign granular permissions — e.g., give RAs quest editing access but not billing access

3. Build the Quest

  1. Create a quest under your organization (Creating a Quest)
  2. Add prompts for recurring data collection if your study needs scheduled surveys (Prompts)
    • Choose response types, categories, and schedules
    • Set up conditional notifications if prompts depend on prior answers
    • Skip this step for experiment-only or recording-only study designs
  3. Add experiments for interactive tasks (Experiments)
    • Write jsPsych code or paste existing experiments
    • Upload stimulus media (images, audio, video)
    • Configure ordering for multi-experiment quests
  4. Configure onboarding for consent and screening (Onboarding)
    • Write a full-text consent overview
    • Add screening questions with question guards
    • Enable kiosk mode if using shared devices
  5. Set up participant operations
    • Create cohorts for the groups you want to track
    • Review the participant roster after enrollment begins
    • Use the quest detail page to configure a simple baseline / follow-up schedule per cohort

4. Fund the Organization

Check your org’s credit balance and purchase credits if needed. Use the price calculator to estimate your total study cost based on participant count, prompts, experiments, and data types.
Quest creation and onboarding responses are free — you only start spending credits when you publish and participants join.

5. Publish and Recruit

  1. Click Publish on your quest
  2. Share with participants via:
    • Direct link — copy the quest URL
    • QR code — for in-person recruitment
    • Prolific — paste the quest URL as your Prolific study URL. Prolific parameters (PROLIFIC_PID, STUDY_ID, SESSION_ID) are captured automatically. See Prolific Integration.

6. Monitor Participants, Responses, and Billing

From the participant and quest workspaces:
  • Participant roster — review who joined, which cohort they belong to, and the current study status
  • Schedule & compliance — set a compact baseline / follow-up schedule and review due / overdue state by participant
  • Response data — view prompt responses, onboarding responses, experiment data, and recordings as they come in
  • Billing summary — track per-quest spending, broken down by item type and source (web vs. mobile)
  • Transaction history — review all credit transactions
  • Audit Log — review which team members viewed, downloaded, deleted, or analyzed data
Fusion still uses Quest as the product term in the UI. In practice, the quest detail and participant pages function as the current study-operations workspace.

7. Export and Analyze Data

  • Export prompt responses, experiment data, and recordings for analysis in your preferred tools (R, Python, SPSS, etc.)
  • On mobile, participants can export experiment data as JSON files
  • Data types available for export:
    • prompt_responses — answers to recurring prompts
    • experiment_trials — jsPsych experiment results
    • brain_recordings — EEG data from Neurosity Crown or Muse
    • health — steps, sleep, heart rate from wearables
    • onboarding_responses — screening question answers

Running a Study with Prolific

If you’re recruiting through Prolific:
  1. Build and publish your quest on NeuroFusion
  2. Copy the quest run URL (e.g., https://usefusion.ai/quest/<guid>)
  3. Create a study on Prolific and paste the quest URL as the study URL
  4. Prolific injects PROLIFIC_PID, STUDY_ID, and SESSION_ID as URL parameters
  5. These are automatically passed to your experiments via jatos.urlQueryParameters
  6. Configure your experiment to redirect to Prolific’s completion URL when finished
See Prolific Integration for the full setup guide.

Tips

  • Test the full flow yourself before launching — join your own quest as a participant to verify onboarding, prompts, and experiments work as expected
  • Check the participant roster early — make sure cohort assignment and participant statuses look correct after the first few joins
  • Monitor billing early — check the expense breakdown after the first few participants to project total costs
  • Use kiosk mode for in-lab studies where multiple participants share the same device
  • Participants can complete experiments on both web and mobile — plan your study design accordingly
