| Abstract: | Psychophysical procedures were used to determine human recognitiontimes to three matched intensity levels of the odorants n-butanol,(+)-limonene and propionic acid. A computer controlled the deliveryof the odorants from an air dilution olfactometer and measuredrecognition times. The mean times recorded with the odorantswere significantly different and ranged between 680–867ms, the shortest times being recorded with the acid. The resultsare discussed in relation to reported detection and recognitiontimes, and their relevance to odor mixture perception, in particularit was concluded that reaction times for recognition do notpredict the occurrence of suppression in mixtures. |
