Test your attention

Quick, validated activities to understand your attention. After each activity, you'll receive feedback from Dr. Fons.

Before you begin

If you choose to play these activities, we'll record a video of you while you do them.

  • Your video is stored confidentially on an encrypted drive.
  • It's used only for research and development — never shared beyond the research team.
  • The raw footage is never used to train any AI model. Only anonymized numerical features are extracted, without identifying information.
  • You can ask us to delete your video at any time. Save the video ID shown after you submit, to reference it in future communication.

By continuing you consent to the recording terms described above.

The activities

Four validated tasks, in the order we recommend.

Each is short and based on established attention research. Take them in sequence for the most useful feedback.

I Go / No-Go Test your inhibition and impulse control — the easier version. II Stop Signal Test your inhibition and impulse control — the more difficult version. III Vigilance Test how vigilant you are over time. IV Sustained Attention to Response Test your capacity to sustain attention across a demanding task.
In collaboration with

These activities and their recordings are part of a large, multi-method deep-dive into human attention by Lifeverse — a team of international scientists, engineers, and designers — in close collaboration with Professor Gloria Mark (UC Irvine, California) and Dr. Maria Carmen Fons Estupiñà (Sant Joan de Déu Hospital, Barcelona).
