“…We used the phonemes /ga/ and /da/ due to their substantial contribution to the meaning of words in various languages of the participants’ countries of origin. There are multiple MMN studies that were conducted with subjects from countries similar to those of our participants and also using phoneme stimuli similar to our stimuli in which a discernible MMN was found (e.g., French: Pang et al, 1998; English: Rivera-Gaxiola, Csibra, Johnson, & Karmiloff-Smith, 2000; Arabian: Zeftawi, 2004). Hence, we may conclude that our participants are familiar with the type of stimuli we used.…”

These days, illiteracy is still a major problem. There is empirical evidence that auditory phoneme discrimination is one of the factors contributing to written language acquisition. The current study investigated auditory phoneme discrimination in participants who did not acquire written language sufficiently. Auditory phoneme discrimination was analyzed in illiterate adults and literate controls by recording event-related brain potentials (ERPs) while participants listened to standard and deviant phonemes (oddball paradigm). The results showed that only literate controls yielded mismatch negativity (MMN), the characteristic ERP marker for auditory discrimination. In illiterates, no discernible MMN was observed. These findings indicate the importance of written language acquisition for the development and maintenance of auditory phoneme discrimination. The reduced ability in discriminating phonemes in adult illiterates suggests potential training measures concerning literacy acquisition in these adults.

“…Näätänen Zeftawi (2004) 22 reported that the primary and nonprimary auditory pathway contribute in MMN generation; the non-primary pathway contribute to the process of durational changes, while the primary pathway contributed to the process of spectro-temporal changes. In the present investigation we found statistically significant differences between durational and spectro-temporal contrasts by latency and duration.…”

Mi smatch Negativity (MMN) is used to evaluate the central auditory system. Aim: to characterize the MMN, in normal subjects. Materials and methods: prospective study, 12 subjects, six males and six females, between the ages of 18 and 24. "Mann-Whytnei" test. Exams: Pure Tone Audiometry (PTA), Tympanometry, Otoacoustic Emissions and Short and Long Latency Auditory Potentials (MMN). Results: in MMN variable amplitude, the mean value was of -2.757 µV and -3.548 µV, CZA1 and CZA2; of 1.435 µV and -1.867 µV, CZA1 and CZA2. In variable and medium latency, we found in 150.7ms and 153.2ms, CZA1 and CZA2; in 170.4ms and 184.0ms, CZA1 and CZA2 -for females and males respectively. Conclusion: related to latency, there was significant statistical difference between the genders in relation to CZA1 and CZA2; and it was lower for females and higher for males.
