Genetics of Laterality, Smell, Taste and Reading
The “Genetics of Laterality, Health and Wellbeing, Personality, Smell Sensitivity, Taste Sensitivity and Reading” study consisted of three components:
- Self report questionnaire
- Smell and taste tests
- Reading task
The aim of the project was to advance understanding of the genetic basis of the following behavioural traits:
- Laterality (Annett Handedness Questionnaire, Footedness and Eyeness Questionnaire)
- Personality (NEO PI-R)
- Olfactory function (National Geographic Smell Test (1986), Brief Smell Identification Test (Sensonics, Inc)
- Taste perception (Monell Taste Test , n-propylthiouracil (PROP))
- Attitudes towards parenting (added November 2002)
