1921 Aberdeen Birth Cohort
On 1st June 1932, as part of the Scottish Mental Survey, 87,498 Scottish schoolchildren born in 1921 sat the same test of mental ability: the Moray House Test. In 1997, the Universities of Aberdeen and Edinburgh began to search for men and women still living in Scotland who took part in these tests.
On 1st June 1998, about 80 individuals gathered in the Aberdeen Music Hall to re-sit the test exactly 66 years later. Participants were followed-up 5 times over a 10 year period.
