Nearly 400 Madison high school graduates took part in aptitude testing in 1960 in response to the country's concern over Russian dominance in space.
The tests were distributed through Project Talent, a national longitudinal study, three years after the Soviet Union launched the Sputnik satellite, the Star Tribune reported. The study emerged in the early 1960s to "diversity of the American high school experience," according to its website.
Now, a third of those who took part in the test are being asked to participate in a new study on aging and dementia.
Questionnaires were recently mailed to the 128 of the 382 East High School graduates from the classes of 1960-63. Participants will receive a new 28-page questionnaire and will be awarded $20 for participating. They could also receive another $20 when they're invited to take a digital survey in the next coming weeks.
Researchers hope to identify factors that help prevent Alzheimer's disease by comparing the test scores from nearly 60 years ago to health status now.
