title: Asymmetry of finger temperature and early behavior.
abstract: Measures of the temperature of the fingertips of eighty-three 4-year-old children revealed an unexpected asymmetry in which the index finger of the left hand but the ring finger of the right hand were the coolest digits. In addition, a subset of 20 children who had the coolest right compared with the left ring finger were more fearful to unfamiliar events and also had a cooler right than left forehead at 21 months of age.
