When human subjects were asked in a binary forced-choice protocol to identify odorant headspaces at different concentrations, the Weber Fraction (I/I) of sequential pairs had a significant effect on the probability of recognition (Rochelle 2017, NI 2021).  This study expanded the earlier work to include a broader range of I/Is and added a variation in Interstimulus Intervals (ISIs). The implication of the results on our understanding of “odor image” formation will be discussed.
