Speech Perception Impairments in Congenital Amusia
Congenital Amusia is an innate disorder affecting auditory perception. So far most research has investigated its influence on music perception. Only few studies have looked at the influence of congenital amusia on speech perception and even these have only investigated the discrimination of pitch differences. The aim of this PhD-project is a systematic investigation of the phonetic impairments in congenital amusics. For this purpose, the project employs behavioural perception experiments and EEG to detect the thresholds of amusics and non-amusics for the following parameters: pitch information (tone differences), temporal information (differences in vowel duration), spectral information (differences in vowel quality) and the combination of spectral and pitch information (differences in word stress and sentence intonation). To exclude native-language influences, the tests are performed both with Dutch and German native speakers.
The resulting thresholds will be compared to the minimal differences in the above-mentioned parameters that are employed in natural languages. This allows us to decide whether congenital amusia poses only low-level auditory impairments or also has severe repercussions on higher-level linguistic knowledge. Both possible outcomes make predictions for the acquisition of certain linguistic parameters.
