Genetics of Laterality, Smell, Taste and Reading

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:

  1. Self report questionnaire
  2. Smell and taste tests
  3. 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)
