Abstract
Event related potentials (ERPs) can provide a valuable on-line record of the cognitive processing involved in speech perception. Every components have shown to be sensitive to speech and non-speech processing mechanism such as MMN, phonological MMN, and N400. This study was designed to investigate if it is possible to use the same behavioral psychological protocols to elicit MMN in the auditory modality. Instruments used in this study were a two channel diagnostic audiometry, a middle Ear Analyzer, and 32-channels brain mapping. This study was done in the out patient clinic of A-SPL department, Brigham Young University in Provo, Utah, USA. This study was performed on 55 adults of both sexes with age range 18-35 years. All subjects in this study were subjected to full history taking, otological examination, basic audiological examination (PTA, SRT, DS); immittancemetry comprising both tympanometry, acoustic reflex threshold testing, event related potential testing. Fourteen neuro-psychology experiments were performed. In experiment 1 to 6 non-verbal test material was used and in experiment 7 to 14 verbal test material was used. This study has high lightened that it is possible to modify the use the tradition non-delayed matching-to-sample protocol commonly used to study memory to elicit MMN. It also showed that changes in the paradigm used to elicit MMN would show a considerable difference in the elicited response. Lastly the study recommended applying the same well-established paradigm of psychology to investigate the ERPs with more researches on better qualitative improvement of the elicited response and more researches on the overlap of different subcomponents.
