The Colorado Longitudinal Twin Study is an ongoing research project of the Institute for Behavioral Genetics, which is a department of the University of Colorado at Boulder. Enrollment of both fraternal and identical infant twins in Colorado began in 1985 and continued for a period of 7 years. Since that time we have collected data from participating twins and their families on a regular basis, conducting home and lab visits at infancy and ages 7, 12, 16 and 17, and telephone interviews during non-visit years. The purpose of this research is to study the varying genetic and environmental influences on development, including cognition, temperament, physical development, intelligence and emotion.
