Project Talent data set from Marion Spengler and Rodica Damian

Description

Project Talent gave 440,000 US high school students a number of personality and ability tests. Of these, the data fror 346,000 were available for followup. Subsequent followups were collected 11 and 50 years later. Marion Spengler and her colleagues Rodica Damian, and Brent Roberts reported on the stability and change across 50 years of personality and ability. Here is the correlation matrix of 25 of their variables (Spengler) as well as a slightly different set of 19 variables (Damian). This is a nice example of mediation and regression from a correlation matrix.

Usage

data("Damian")

Format

A 25 x 25 correlation matrix of demographic, personality, and ability variables, based upon 346,660 participants.

Race/Ethnicity: 1 = other, 2 = white/caucasian
Sex: 1=Male, 2=Female
Age: Cohort =9th grade, 10th grade, 11th grade, 12th grade
Parental: Parental SES based upon 9 questions of home value, family income, etc.
IQ: Standardized composite of Verbal, Spatial and Mathematical
Sociability etc.: 10 scales based upon prior work by Damian and Roberts
Maturity: A higher order factor from the prior 10 scales
Extraversion: The second higher order factor
Interest: Self reported interest in school
Reading: Self report reading skills
Writing: Self report writing skills
Responsible: Self reported responsibility scale
Ed.11: Education level at 11 year followup
Educ.50: Education level at 50 year followup
OccPres.11: Occupational Prestige at 11 year followup
OccPres.50: Occupational Prestige at 50 year followup
Income.11: Income at 11 year followup
Income.50: Income at 50 year followup

Details

Data from Project Talent was collected in 1960 on a representative sample of American high school students. Subsequent follow up 11 and 50 years later are reported by Spengler et al (2018) and others.
