Trial design

Participants with autism (n=30)Age-matched controls (n=30)
A 1 h interview to characterise autism and potentially stressful events
Phase 1A 24 h pre-experimental recording for baseline (sleep, physical activity)A 24 h pre-experimental recording for baseline (sleep, physical activity)
Phase 2A 2 h experimental recording in a real life situationA 2 h experimental recording in a real life situation
Phase 315 min recording in a quiet environment, followed by a few seconds of stressful sound, followed by 15 min recording in a quiet environment15 min recording in a quiet environment, followed by a few seconds of stressful sound, followed by 15 min recording in a quiet environment
Phase 4Interview to get comments on feelings about events that triggered anxietyInterview to get comments on feelings about events that triggered anxiety
  • In yellow: During the 2 h experimental recording in real life and the 30 min recording in a quiet environment interrupted by a few seconds of stressful sound, the participant with autism and the age-matched control will be together, revealing different physiological responses to the same situations.
