Genetic and environmental influences on autistic-like behaviors in 2-year-old twins.

Behavior genetics - 1 May 2009

Edelson Lisa R, Saudino Kimberly J

Abstract excerpt

This study aims to explore the genetic and environmental contributions to autistic-like behaviors in a general population sample of toddlers. In a classic twin study of 313 same-sex, 2-year-old twin pairs, autistic-like behaviors were assessed via parent ratings on the pervasive developmental problems subscale of the Child Behavior Checklist and observationally using tester ratings on the orientation/engagement...
