Terman Life Cycle Study of Children with High Ability

Study Overview


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.

Sampling Procedures: 

1,528 children living in California in 1922, with birthdates scattered around a mean of 1910, with a standard deviation of 4 years. By the final followup, there were 812 participants remaining in the study.
