Two studies examined the effects of the appearance of specific facial featu
res on attributions of personality. In Study 1,photographs of men and women
were computer-manipulated to have larger than average or smaller than aver
age eye size, and wider than average or narrower than average eye spacing.
In Study 2, eye size and mouth fullness were similarly altered. Although it
was found that neither eye spacing nor mouth fullness had any effect on pe
rceptions of the targets' personality or physical characteristics, eye size
had strong effects in both studies. Analyses of covariance revealed that t
he personality trait ratings that varied with eye size were mediated primar
ily by perceived differences in the targets' masculinity-femininity and bab
yfacedness, and to a lesser extent by attractiveness.
