“Reviving the Louisville Twin Study: An Introduction”, 2015-10-26 (; backlinks):
Researchers who are interested in breathing new life into the long dormant Louisville Twin Study (LTS) presented several papers at the 2015 meeting of the behavior genetics association.
This brief introduction provides a short history of the Kentucky LTS as well as synopses of expanded analyses from the presentations on genetic change and continuity in cognitive and behavioral development and those exploring aspects of the influence of gene-environment interaction on cognition.
In addition to publishing the abstracts from the 2015 meeting of the behavioral genetics association, most of the remainder of this volume is devoted to papers developed from one of the paper sessions—“Resuscitating the Louisville Twin Study: A Symposium in Honor of Adam P. Matheny.” As a coordinator of another LTS—the Colorado Longitudinal Twin Study—I was heartened to learn that old twin studies never die, they just replicate and regenerate. The replication, of course, is that the Kentucky LTS provided the foundation for the proliferation of longitudinal twin studies around the world. And now we are witnessing the regeneration of the Kentucky LTS as researchers reanalyze the extant data, uncover buried treasures in the archives, and make the case for re-contacting and retesting participants as aging adults. Preliminary results were presented at the 2015 BGA meeting and expanded analyses are presented here.
