Stability of babyfaceness and attractiveness across the life span.

Differential, structural, and absolute stability of babyfaceness and attractiveness at 5 ages were investigated. Attractiveness had differential stability across the life span. Babyfaceness had differential stability from childhood through the 30s for males and through adolescence for females. Consistent with sexual dimorphisms in facial maturation, males had less differential stability in babyfaceness from childhood to puberty than females. Structural stability of facial appearance, as reflected in the relationship between babyfaceness and attractiveness across the life span, was low, with these qualities positively related for females in childhood and for both sexes in their 30s and 50s but unrelated in puberty and adolescence. Absolute stability of babyfaceness and attractiveness was also low, with mean levels decreasing across the life span. Contrary to cultural stereotypes, age-related decreases in attractiveness were equal for male and female Ss.
