  abstract  = {In W{\"u}rzburg wurden seit der Implantation des ersten Cochlea-Implantats (CI) 1991 bis heute 449 Ohren implantiert (Stand 03/2003). Im Rahmen der vorliegenden Studie wurde an einem Kollektiv von 148 erwachsenen Patienten, die mit einem CI der Firma MED-EL (Innsbruck) versorgt worden waren, die zeitliche Entwicklung der Sprachverst{\"a}ndlichkeit anhand verschiedener Sprachtests sowie der Einfluss verschiedener Faktoren auf das Ausmaß des auditiven Erfolges untersucht. Als Testmaterial f{\"u}r die CI-Patienten dienten die g{\"a}ngigen auch in W{\"u}rzburg verwendeten Sprachverst{\"a}ndnistests: Freiburger Zahlen-/W{\"o}rtertest und HSM-Satztest. Die Patienten konnten ihre Ergebnisse in allen untersuchten Sprachtests im Laufe der Zeit steigern, das heißt sie verstanden mit zunehmender Tragedauer immer besser. Die statistische Analyse zeigte einen signifikanten Zusammenhang zwischen dem Anstieg der Sprachverst{\"a}ndlichkeit und der Zeit nach Erstanpassung des CIs. Desweiteren wurde untersucht, ob die Ertaubungsdauer, die Ergebnisse im Promontorialtest, wie auch die Gabe von Cortison die postoperative Sprachverst{\"a}ndlichkeit beeinflussten. Dabei konnte gezeigt werden, dass die Ertaubungsdauer einen signifikanten Einfluss auf die postoperativen Sprachergebnisse hatte. Kein signifikanter Zusammenhang konnte dagegen zwischen den Werten im Promontorialtest bzw. zwischen der Gabe von Cortison und der postoperativen Sprachverst{\"a}ndlichkeit gefunden werden.},

  abstract  = {Dyslexia affects 5-10\% of school-aged children and is therefore one of the most common learning disorders. Research on auditory event related potentials (AERP), particularly the mismatch negativity (MMN) component, has revealed anomalies in individuals with dyslexia to speech stimuli. Furthermore, candidate genes for this disorder were found through molecular genetic studies. A current challenge for dyslexia research is to understand the interaction between molecular genetics and brain function, and to promote the identification of relevant endophenotypes for dyslexia. The present study examines MMN, a neurophysiological correlate of speech perception, and its potential as an endophenotype for dyslexia in three groups of children. The first group of children was clinically diagnosed with dyslexia, whereas the second group of children was comprised of their siblings who had average reading and spelling skills and were therefore "unaffected'' despite having a genetic risk for dyslexia. The third group consisted of control children who were not related to the other groups and were also unaffected. In total, 225 children were included in the study. All children showed clear MMN activity to/da/-/ba/ contrasts that could be separated into three distinct MMN components. Whilst the first two MMN components did not differentiate the groups, the late MMN component (300-700 ms) revealed significant group differences. The mean area of the late MMN was attenuated in both the dyslexic children and their unaffected siblings in comparison to the control children. This finding is indicative of analogous alterations of neurophysiological processes in children with dyslexia and those with a genetic risk for dyslexia, without a manifestation of the disorder. The present results therefore further suggest that the late MMN might be a potential endophenotype for dyslexia.},

  abstract  = {Objectives: To assess the subjective and objective performance of the new fine structure processing strategy (FSP) compared to the previous generation coding strategies CIS+ and HDCIS. Methods: Forty-six adults with a minimum of 6 months of cochlear implant experience were included. CIS+, HDCIS and FSP were compared in speech perception tests in noise, pitch scaling and questionnaires. The randomized tests were performed acutely (interval 1) and again after 3 months of FSP experience (interval 3). The subjective evaluation included questionnaire 1 at intervals 1 and 3, and questionnaire 2 at interval 2, 1 month after interval 1. Results: Comparison between FSP and CIS+ showed that FSP performed at least as well as CIS+ in all speech perception tests, and outperformed CIS+ in vowel and monosyllabic word discrimination. Comparison between FSP and HDCIS showed that both performed equally well in all speech perception tests. Pitch scaling showed that FSP performed at least as well as HDCIS. With FSP, sound quality was at least as good and often better than with HDCIS. Conclusions: Results indicate that FSP performs better than CIS+ in vowel and monosyllabic word understanding. Subjective evaluation demonstrates strong user preferences for FSP when listening to speech and music.},
