title: Year-By-Year Changes In Personality From Six To Eighteen Years.
abstract: Teacher trait-ratings on 42 bipolar traits were obtained for 660 school children (26 boys and 26 girls from Kindergarten through Grade 12). The trait-ratings were transformed into factor scores on Cattell's 16 basic personality factors. Year-by-year cross-sectional analysis of the trait-ratings and factor scores yielded significant sex and age differences throughout the school age period.
