“…Although a number of researchers have found that boys perceive themselves as significantly more assertive than girls by early adolescence (Ahlgren & Johnson, 1979;Dusek et al, 1981;Galambos et al, 1990;Leahy & Eiter, 1980;Roberts, Sarigiani, Petersen, & Newman, 1990), others have found no gender differences in adolescent assertiveness, or that adolescent girls report being more assertive or autonomous in their relationships than boys do (Buhrmester et al, 1988;Hibbard, Tao, & White, 1997;Sharabany et al, 1981;Steinberg & Silverberg, 1986). Eccles, Barber, Jozefowicz, Malenchuk, and Vida (1999) found no gender differences in adolescents' self-ratings of leadership or independence while Feldman et al (1981) found that gender differences in assertiveness did not develop until later in life.…”
