Fechner Day Conferences
Fechner Day is the annual meeting of the International Society for Psychophysics. The conference honors Gustav Theodor Fechner, whose October 22, 1850 insight helped set the path toward the 1860 foundations of psychophysics and the quantitative study of sensation and perception.
This page preserves the society’s long-term conference record, from the first meeting in Marseille in 1985 to the current Fechner Day series. Current meeting information, registration details, and recent conference archives are maintained on the Fechner Day website.
