The present study investigates the possible relationship between motion sickness susceptibility, personality factors and salivation. Personality factors, as evaluated by the Eysenck Personality Questionnaire, and salivary composition and flow were measured in a group of 29 subjects highly susceptible to seasickness and in a group of 25 non-susceptible subjects. The nonsusceptible group had significantly higher psychoticism scores and significantly lower salivary amylase levels compared to the highly susceptible group. A significant positive correlation was found between psychoticism scores and the amount of the increase in salivary flow in response to gustatory stimulation. These results provide more data in support of a connection between motion sickness susceptibility, personality, and the autonomic nervous system.
