Gustav Fechner
Fechner, along with Wilhelm Wundt and Hermann von Helmholtz, is recognized as one of the founders of modern experimental psychology. His clearest contribution was the demonstration that because the mind was susceptible to measurement and mathematical treatment, psychology had the potential to become a quantified science. Theorists such as Immanuel Kant had long stated that this was impossible, and that therefore, a science of psychology was also impossible.
Floyd Henry Allport
Allport achieved the following awards during his career:
Allport is most notably recognized as the founder of the modern field of social psychology. He was the first to write a dissertation in the US on social psychology (called "The social influence: An experimental study of the effect of the group upon individual mental processes"). He challenged much of the way of thinking of his day by focusing on behavioral interpretations of social themes and stressing individuals rather than groups as the agents of social behavior, in which context he coined the terms social facilitation and producing tendency. His work includes research on social influence, convergence and conformity, personality theory, and measurements of attitudes.
