Summary
This study links motion sickness susceptibility to personality traits and salivary responses. Non-susceptible individuals showed higher psychoticism and lower salivary amylase, suggesting connections to the autonomic nervous system.
Area of Science:
- Neuroscience
- Psychology
- Physiology
Background:
- Motion sickness susceptibility varies among individuals.
- Personality traits may influence physiological responses.
- Salivary composition and flow are linked to autonomic nervous system activity.
Purpose of the Study:
- To investigate the relationship between motion sickness susceptibility, personality factors, and salivation.
- To compare salivary characteristics and personality scores between seasickness-susceptible and non-susceptible groups.
Main Methods:
- Assessed personality factors using the Eysenck Personality Questionnaire.
- Measured salivary composition and flow rate in 29 highly susceptible and 25 non-susceptible subjects.
- Analyzed correlations between personality scores, salivary parameters, and gustatory stimulation response.
Main Results:
- Non-susceptible subjects exhibited significantly higher psychoticism scores.
- Non-susceptible subjects had significantly lower salivary amylase levels.
- A positive correlation was observed between psychoticism scores and salivary flow increase upon gustatory stimulation.
Conclusions:
- Findings support a link between motion sickness susceptibility, personality traits (specifically psychoticism), and salivary responses.
- Results suggest the involvement of the autonomic nervous system in the interplay between motion sickness, personality, and salivation.
