The Effect of Inter-Trial Interval on the Variability of Odor Perceived Intensity

Abstract:

The effects of inter-trial interval on the stability of odor perceived intensity has been investigated in this paper. One min, three min and five min were set as intervals and the results showed that odor perceived intensities in the replicate experiments are relative stable when inter-trial interval is 1 min or 5 min. With a fixed inter-trial interval, the odor quality and odor intensity level have no significant effect on the variability of the odor perceived intensity; whereas, the variability of the perceived intensity is related to the odor quality at different inter-trial interval.
