Normative Data for Tonal Auditory Temporal Processing Tests in Persian-Speaking Adults

Auditory temporal processing is the perception of sound or perception of sound changes within a short time interval and seems to be a major capability in the perception of speech and non-speech sounds, music, rhythm and periodicity. Auditory temporal processing is also considered as an essential ability in discrimination of pitch, duration of acoustic signals and phoneme. Several tests have been developed to assess auditory temporal processing; the most popular of these tests are Duration Pattern Sequence Test (DPST), Pitch Pattern Sequence Test (PPST), and Random Gap Detection Test (RGDT).
The current study was carried out on 100 monolingual individuals (people with Persian language) with normal hearing including 50 females and 50 males. DPST, PPST, and RGDT were performed for all cases.
The means and standard deviations for DPST, PPST, and RGDT were %96.61 ± 4.51, %89.78 ± 7.72, and 8.07 ms ± 3.56, respectively. The results revealed no significant differences between the results of women and men in any of the tests (P>0.05). The statistical results showed no significant differences between right and left ears scores in monaural tests (P>0.05).
According to the statistical analysis, it seems that normative data obtained in the present study could be used as a diagnostic tool for determination of auditory cortical lesions in adults.
