Abstract
Examined the modifiability and heritability of reflection-impulsivity as measured by Matching Familiar Figures. A co-twin control study of 3 pairs of 4-yr-old identical twins was conducted to study the modifiability of the trait. The heritability of the trait was investigated by a twin study of 54 pairs of 3- to 6-yr-old twins. The co-twin study suggests little modifiability of reflection-impulsivity, and the twin study suggests that some of the resistance to change may be due to genetic factors.
