Adolescent Twin Study
The MSUTR Adolescent Twin Study of Behavioral Adjustment and Development is a study of 206 same-sex male, 312 same-sex female, and 120 opposite-sex twins between the ages of 10 and 16 years old. The primary purpose of the study was to investigate genetic, environmental (e.g., teasing by peers, parent-adolescent relationships), and neurobiological (i.e., gonadal hormones) risk factors for disordered eating, antisocial behavior, mood, attention/hyperactivity problems, and temperament during early adolescence. In particular, this study aimed to understand whether these psychological characteristics are related to gonadal hormone levels during puberty, whether relationships amongst these factors are influenced by genes, and whether gene x environment interactions influence their development.

Famous quotes containing the words adolescent, twin and/or study:
“Although good early childhood programs can benefit all children, they are not a quick fix for all of society’s ills—from crime in the streets to adolescent pregnancy, from school failure to unemployment. We must emphasize that good quality early childhood programs can help change the social and educational outcomes for many children, but they are not a panacea; they cannot ameliorate the effects of all harmful social and psychological environments.”
—Barbara Bowman (20th century)
“We live under continual threat of two equally fearful, but seemingly opposed, destinies: unremitting banality and inconceivable terror. It is fantasy, served out in large rations by the popular arts, which allows most people to cope with these twin specters.”
—Susan Sontag (b. 1933)
“The life of a good man will hardly improve us more than the life of a freebooter, for the inevitable laws appear as plainly in the infringement as in the observance, and our lives are sustained by a nearly equal expense of virtue of some kind. The decaying tree, while yet it lives, demands sun, wind, and rain no less than the green one. It secretes sap and performs the functions of health. If we choose, we may study the alburnum only. The gnarled stump has as tender a bud as the sapling.”
—Henry David Thoreau (1817–1862)
