Yawning as a Behavioral Marker of Mild Motion Sickness and Sopite Syndrome

Mild motion sickness and sopite syndrome, a symptom-complex related to motion sickness, can impact a person's ability to perform assigned tasks. However, mild motion sickness and sopite syndrome lack clear behavioral markers and are not easily identified. The objective of this study is to investigate yawning as one such behavioral marker. Thirty-nine healthy individuals participated in two 1-hour sessions and performed a multitasking battery on a head mounted display while seated on a moving platform. Yawning and motion sickness data were collected and symptoms were assessed with the Motion Sickness Assessment Questionnaire (MSAQ). Results showed that subjects who yawned while in motion had increased severity of motion sickness and symptoms of drowsiness, along with reduced cognitive performance while multitasking. The results indicate that yawning is associated with and may be a viable behavioral marker for motion sickness and sopite syndrome.
