Several lines of research currently utilize
data from the Wisconsin Twin Panel. The Twin
Autism Project (TAP) focuses on the autism spectrum.
This project examines several behavioral features of autism,
as well as identical and fraternal twin similarity. In collaboration
with Dr. Morton Ann Gernsbacher and others, TAP is a partnership
between the Wisconsin Twin Project (WTP) and the University
of Wisconsin Research on Autism (UWRA).
Twin Project (WTP) is a study of young children at risk
for (1) internalizing problems such as anxiety, social withdrawal,
and depression; (2) externalizing problems, such as oppositional
and conduct problems, and disinhibition; and (3) attentional
problems, particularly attention deficit hyperactivity disorder
(ADHD). The project approaches behavioral disorders with
the conceptual and empirical tools of developmental psychobiology
in addition to the more typical clinical orientation. WTP
is a co-directed by Dr. Kathryn Lemery-Chalfant.
The fine-grained, longitudinal Genetics
of Emotional Ontogeny (GEO) project addresses the nature,
sources, and functional consequences of emotional individuality
from birth to age 3 years. Another project has extended
work with these infant twins to a new sample of 6-9 year-old
twins, with the inclusion of measures to provide a comprehensive
assessment of physiology related to affective reactivity,
and particularly to anxiety.
