The Wisconsin Twin Research laboratories,
directed by Dr. Hill Goldsmith, investigate genetic and
environmental features of emotional development from infancy
to adolescence. Three major research projects are underway.
The Genetics of Emotional Ontogeny (GEO) project examines
typical behavioral development from birth to age seven.
The Wisconsin Twin Project (WTP) considers both typical
development and behavioral problems, and it extends from
early childhood to adolescence. The Twin Autism Project
(TAP) examines development of children and adolescents
on the autism spectrum.
