Morphosyntax, prosody, and linking elements: the auditory processing of German nominal compounds.

Area of Science:

• Psycholinguistics
• Neuroscience
• Computational Linguistics

Background:

• German compound words pose challenges for morphosyntactic decomposition.
• The function of linking elements in compounds is debated.
• Auditory processing of complex word structures remains an active research area.

Purpose of the Study:

• To investigate the morphosyntactic decomposition of German compound words during auditory processing.
• To examine the proposed function of linking elements as indicators of nonhead constituent number.
• To explore the role of prosody in differentiating compounds from single nouns.

Main Methods:

• Event-related potentials (ERPs) were used to measure brain activity.
• Experiments manipulated syntactic gender and number agreement within compound words.
• Prosodic cues (duration, fundamental frequency) were varied in Experiment 3.

Main Results:

• Incongruent gender agreement for both compound constituents elicited left-anterior negativity, suggesting decomposition.
• Number-incongruent heads elicited N400 and negativity, indicating linking elements are not plural markers.
• Prosodic cues influenced ERPs, differentiating compounds from single nouns and linking elements from plural morphemes.

Conclusions:

• German compound words undergo morphosyntactic decomposition.
• Linking elements do not function as plural morphemes.
• Prosody plays a crucial role in the auditory processing of compounds and distinguishing them from single words.
