Abstract
Experiments with two odorants, acetic acid and propionic acid, have provided additional evidence that jnds are a constant fraction of the stimulus strength. A linear plot of the difference limens and stimulus intensities has yielded a K of 0.28 for olfactory discrimination in man. The treatment of data derived from tests above the 50% limen and the over-all concept of jnd discrimination are discussed.Keywords
