This study of the personal and life characteristics of
children with high ability follows the 1,528 respondents from 1922
through the latest series of interviews with the surviving cohort of
720 in 1986. The original research objectives were to replace myths
about intellectually superior children with documented facts. In 1922,
the children were identified on the basis of an intelligence test as
being in the top one percent of the population. Their development was
followed over the next sixty years via questionnaires, personal
interviews, and various test instruments. Questions were asked about
their health, physical and emotional development, school histories,
recreational activities, home life, family background, educational,
vocational, and marital histories. Questions were also asked about
income, emotional stability, and socio-political attitudes. The
follow-up questionnaires were concerned with the evolution of the
respondents' careers, activity patterns, and personal adjustment. Since
1972 there has been special emphasis on the aging process. These
longitudinal data will continue to be collected as long as living
members of the original cohort contribute data.
