About the meeting

Fechner Day is the annual meeting of the International Society for Psychophysics (ISP). The 42nd meeting will be hosted by the Department of Psychology at Umeå University.

The conference provides a forum for research on the relationships between physical stimuli and perceptual experiences, including classical and modern psychophysical methods, modelling approaches and applications across the senses.

In Umeå, we aim to create a focused, friendly environment that supports scientific exchange across career stages, with a particular emphasis on graduate student participation.
