Question

What is the difference between inner psychophysics and outer psychophysics? Which was Fechner forced to focus on? Why?

Answer 1

Answer:
Inner psychophysics is define as It is link between the mind or brain & the percept. It consist mind-body problem.

Outer psychophysics define as the connection between the percept and stimuli.
It consist distal stimulus and proximal stimulus.
Outer psychophysics can be looked as a combination of forward problem & inverse problems.

This is a forward problem & it is explained by the physics rules. While proximal stimulus percept is an inverse problem & it consist perceptual inferences.
An effort to mandate the direct union between the tangible intensity of sensory stimulants and the intensity of the corresponding cognitive experience.
Gustav Fechner proposed & explained the concept of outer psychophysics. Fechner gave more importance to the inner psychophysics because it consist mind and body problem and its connection.
