Odor threshold scores for guaiacol (GUA), a smoke-like odorant, and phenyl ethyl alcohol (PEA), a rose-like odorant, in adults impaired and not impaired by their odor sensitivity (OSI and OS, respectively). Odor detection was determined with the Snap and Sniff ® Threshold Test (SSTT), wherein a lower number (more negative) indicated a lower concentration of odorant and enhanced detection. Overall, the entire sample showed enhanced detection of GUA compared to PEA. This effect was driven mainly by the OSI group who demonstrated significantly enhanced detection for GUA compared PEA. * = p < .05.
