James wrote considerably on the concept of pragmatism. According to pragmatism, the truth of an idea can never be proven. James proposed we instead focus on what he called the "cash value," or usefulness, of an idea.
James opposed the structuralism focus on introspection and breaking down mental events to the smallest elements. Instead, James focused on the wholeness of an event, taking into the impact of the environment on behavior.
The James-Lange theory of emotion proposes that an event triggers a physiological reaction, which we then interpret. According to this theory, emotions are caused by our interpretations of these physiological reactions. Both James and the Danish physiologist Carl Lange independently proposed the theory.

Freud admired Fechner as the pioneer of psychophysics and a founder of scientific and experimental psychology
He set out the foundations of psychophysics, such as the Fechner-Weber law, by which he is remembered as a founder of experimental psychology.
In this latter work Fechner offers the "principle of constancy" to explain how a progressively ordered and structured system can evolve from a disorganized state, a notion that suggests Freud's famous formula.
Fechner was a role model for Freud, thus he was a member of the psychoanalytic branch.
G. Stanley Hall
Born: February 01, 1844 in Ashfield, Massachusetts, United States
Died: April 24, 1924 in Worcester, Massachusetts, United States In 1884 Hall set up an experimental psychology laboratory (the first in the United States) at Johns Hopkins University, affiliated with the biology department
There he investigated motor sensations of the skin, the perception of rhythm, and other aspects of physiological psychology. But he also developed an interest in the unconscious mind, specifically hypnosis, and as a result grew increasingly disenchanted with this completely somatic approach to psychology, the processes of which now seemed to him to require more complex explanations than those offered by physiology. Hall's new interests were parallel to those of Sigmund Freud, the Austrian psychiatrist whose papers on hysteria Hall had read in the 1890s.
He would either be a member of the biological branch or the psychoanalytical branch.
