Background and Aim: Temporal resolution refers to the ability of perceiving changes over time. This study was conducted to prepare Persian version of the temporal resolution test, which was first introduced by Phillips (1994) and Stuart (1996), and to obtain its results in 18 to 25 year old normal individuals of both genders.
Methods: To construct the Persian version of the temporal resolution test, like the original version, speech stimuli, continuous and interrupted noises were used. Speech stimuli comprised four lists of fifty words-monosyllabic lists, which were presented to the right ears first in quietness and then with continuous and interrupted noises on S/Ns of -20, -10, 0, +10 dB. The test was performed on thirty three right handed healthy individuals (14 male and 19 female with the mean age 21.02, SD=1.7 year old) in written response mode.
Results: Significant difference was shown between test scores in quiet with each of the continuous (p<0.0001) and interrupted (p≤0.0001) noises in four signal to noise ratios, and also between test scores of continuous and interrupted noise presentations (p<0.0001). No significant correlation was revealed between gender and test scores and age and test score and age in +10 dB S/N ratio.
Conclusion: Conducting this test on a group of healthy individuals showed its application for measuring temporal resolution with speech stimuli.

Keywords: Temporal resolution, continuous noise, interrupted noise, signal to noise ratio
