Temperament and personality as functions of age

Age-related differences in three temperament (Trait Pleasure-displeasure, Trait Arousability, Trait-Dominance-submissiveness), and four personality (Achieving Tendency, Conformity, Shyness, Loneliness), scales were explored in three studies. Results, generally, were consistent with the hypothesis that scores on Trait Dominance and on trait measures that correlated positively with Trait Dominance (e.g., achievement) were lower for older persons. Achieving Tendency (assessed in Studies One and Three) was lower for older persons. Trait Dominance (assessed in 2 studies) was lower for older men and women in Study Two and lower for older women only in Study Three. In Study Three, two strong negative correlates of Trait Dominance (Conformity, Shyness) were higher for older women. Based on a consistent absence of age/Trait Pleasure relationships, no age-related differences in psychological adjustment-maladjustment were implied by the findings.
