What contributes did christine ladd franklin make to psychology

History

Ladd-Franklin's mathematical interests ultimately led her to make important contributions to the field of psychology. In 1886, she became interested in the geometrical relationship between binocular vision and points in space and published a paper on this topic in the first volume of the American Journal of Psychology the following year. During the 1891-92 academic year, Ladd-Franklin took advantage of her husband's sabbatical leave from Johns Hopkins and traveled to Europe to conduct research in color vision in the laboratories of George Müller (1850-1934) in Göttingen, and Herman von Helmholtz (1821-1894) in Berlin, where she also attended lectures by Arthur König. In contrast to the prevailing three-color and opponent-color explanations of color vision, Ladd-Franklin developed an evolutionary theory that posited three stages in the development of color vision. Presenting her work at the International Congress of Psychology in London in 1892, she argued that black-white vision was the most primitive stage, since it occurs under the greatest variety of conditions, including under very low illumination and at the extreme edges of the visual field. The color white, she theorized, later became differentiated into blue and yellow, with yellow ultimately differentiated into red-green vision. Ladd-Franklin's theory was well-received and remained influential for some years, and its emphasis on evolution is still valid today.

What were the major failings of the Dawes Act? (Site 1)
satela [25.4K]

Answer:

Historian Eric Foner believed "the policy proved to be a disaster, leading to the loss of much tribal land and the erosion of Indian cultural traditions." The law often placed Indians on desert land unsuitable for agriculture, and it also failed to account for Indians who could not afford the cost of farming. In addition to scant payment, Native Americans were not used to spending money and quickly spent most of what they received. Many were left with little land and little money. Inheritance also became an issue for many Native Americans who enrolled to receive land from the Dawes Act. The assimilation policy of the Dawes Act failed because it didn't take into account the social and cultural differences between the Native Americans and the white settlers. Many others like the Kiowas didn't want to assimilate into white culture and as such resisted.
