Abstract
Change in the human infant''s respiration was used as an index of the intensity of homologous alcohols. At 100% concentration intensity decreases but at threshold concentration intensity increases with increasing chain length. Psychophysical scaling with adult Os indicates that the infant results are not inconsistent because the slope of the psychophysical function also decreases with increasing chain length. These findings are pertinent to olfaction as well as psychophysics.
