Understanding how people make sense of written language remains challenging since reading involves multiple parallel and interactive cognitive processes. By using the international Morse code as a novel model for language decoding, new opportunities arise to address some challenges associated with written scripts. In this work, the possibilities and limitations of Morse code as a model for language decoding were investigated using brain imaging methods such as functional magnetic resonance imaging and magnetoencephalography. Using computational models to guide univariate and effective connectivity analyses, various brain regions were identified and assigned to different subprocesses involved in decoding. Furthermore, it could be shown that language decoding benefits from multisensory experiences in multiple ways. Thus, the Morse code represents a novel approach to investigate language decoding from a new perspective, allowing to target some challenges in language research.
Zu verstehen, wie Menschen geschriebene Sprache verstehen, bleibt herausfordernd, da das Lesen mehrere parallele und interaktive kognitive Prozesse involviert. Durch die Verwendung des internationalen Morse-Codes als Sprachmodell ergeben sich neue Möglichkeiten, diese Herausforderungen anzugehen. In dieser Arbeit wurden die Möglichkeiten und Grenzen dieses Modells mittels bildgebender Verfahren wie der funktionellen Magnetresonanztomographie und der Magnetoenzephalographie untersucht. Mittels univariater und effektive Konnektivitätsanalysen konnten mehrere Hirnregionen identifiziert werden, die an verschiedenen Teilprozessen der Sprachdekodierung beteiligt sind. Zusätzlich konnte gezeigt werden, dass die Sprachdekodierung mehrfach von multisensorischen Erfahrungen profitiert. Somit stellt der Morsecode einen geeigneten Ansatz dar, um die Sprachdekodierung aus neuen Perspektiven zu untersuchen und einige Herausforderungen der Sprachforschung anzugehen.
