Carol Gilligan believed earlier researchers into morality had overlooked the perspective of females.

Explanation:

Gilligan was Kohlberg's reserach assistant, but argued that Kohlberg's stages of moral development were male-orientated. Therefore, these stages were limited in there ability to be generalized to females. Because of these, Gilligan  proposed her theory of stages of female moral development.
