Final answer:
Jean Baker Miller's work highlighted women's roles in nurturing development in others, marking an important aspect of feminist psychology. This field arose to combat biases in traditional psychology, and historical evidence counters the false notion that women were incapable of handling wartime burdens.
Step-by-step explanation:
Jean Baker Miller, in her work Toward a New Psychology of Women, described the tendency of women to nurture the emotional, intellectual, and social development of others. This concept aligns with the emergence of feminist psychology, a discipline that attempts to address and correct the biases and misconceptions present in traditional psychological theories formed by men.
Historically, women's contributions to psychology, as noted by pioneers like Margaret Floy Washburn and Mary Whiton Calkins, were significant yet often overlooked. It wasn't until feminist voices such as Naomi Weisstein's critique of psychology and Betty Friedan's influential work, The Feminine Mystique, that a more equitable understanding of women’s roles and psychology began to emerge. These developments acknowledged that contrary to some culturally biased views, women were capable of handling various societal and family burdens—including those brought on by war—effectively refuting the statement that many women found themselves 'incapable of handling the burdens of war when their husbands and fathers went off to fight,' which is false.
