Subjective Intensity of the Lily-of-the-Valley Scent

14 blind-folded subjects were requested to give numerical judgments of the perceived intensities of 1/4, 1/2, 1, 2, 4, 8, lily-of-the-valley bunches, according to a naturalistic approach. The psychophysical function conforms to a power law. The exponent, smaller than 1, is in the same range as those commonly found for smell.
