Summary
Chewing side preference (CSP) is a reliable indicator of hemispheric lateralization in adults. This finding suggests CSP can be used alongside peripheral organ preference tests to assess brain lateralization.
Area of Science:
- Neuroscience
- Human Physiology
Background:
- Hemispheric lateralization, the specialization of brain functions in one hemisphere, is a fundamental aspect of human cognition.
- Understanding the factors influencing lateralization is crucial for neuroscience research.
Purpose of the Study:
- To determine if chewing side preference (CSP) can serve as an indicator of hemispheric lateralization in healthy adults.
- To explore the relationship between CSP and the preference of peripheral organs.
Main Methods:
- Seventy-five healthy adult participants were recruited for the study.
- Chewing side preference was assessed using the visual analogue scale (VAS).
- Laterality tests were administered to determine preferred peripheral organs (hand, foot, ear, eye).
Main Results:
- A significant positive correlation was observed between chewing side preference and the preferred side for hand, foot, ear, and eye.
- Statistical analysis revealed significant associations (e.g., r = .41, p < .001 for hand preference).
Conclusions:
- Chewing side preference is a valid indicator of hemispheric lateralization.
- CSP can be utilized in conjunction with peripheral organ preference tests for assessing brain lateralization.
