Wisconsin Twin Project (WTP) is a research project
of all twins born in Wisconsin since 1989. The main
focus of the research is social-emotional development,
behavioral challenges, and behavioral adaptation in
the family context at different ages (across time).
Areas of interest include challenges and risk factors
as well as adaptive processes and competence factors
that contribute to child development.
Currently, families are contacted at three points
in time: toddlerhood (age 2-3);
school age (6-8), and adolescence (12-18). Families
are contacted by phone and invited to participate
in a variety of ways, sometimes only a phone interview,
sometimes mailed questionnaires, and sometimes a home
visit. (See the specific age studies for more details.)
Twin research is important because it provides a
unique opportunity to examine individual differences
and genetic and environmental influences on child
development. The results should improve understanding
of how child behaviors develop from toddlerhood through
adolescence. Results may provide insight to questions
such as: do shy toddlers develop into shy adolescents;
are outgoing children less fearful; and how do characteristics
such as cognition and activity level relate to emotion.
The Wisconsin Twin Project is located in the Waisman
Center at the University of Wisconsin-Madison. The
Waisman Center's mission is to advance knowledge about
human development, developmental disabilities, and
Funding for the twin project is provided by grant
awards from the National Institute of Health and the
University of Wisconsin-Madison.
