Prosody-assisted head-driven access to spoken German compounds.

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Computational Linguistics

Background:

• Understanding how humans process compound words, especially in the auditory domain, is crucial for psycholinguistics.
• German compound words, characterized by their structure, offer a unique model for investigating lexical access.
• Previous research has explored semantic priming but auditory processing of compounds requires further elucidation.

Purpose of the Study:

• To investigate the processing of German two-noun compound words presented auditorily.
• To determine the role of constituent primacy in the mental lexicon access of auditory compound words.
• To explore the influence of constituent transparency and prosodic structure on compound word processing.

Main Methods:

• Utilized semantic priming paradigms across four experiments with 328 participants.
• Monitored semantic priming effects of the left constituents of auditorily presented German compound words.
• Analyzed the impact of the right constituent's transparency and the prosodic structure of initial morphemes.

Main Results:

• No evidence for left-constituent primacy in accessing auditorily presented German compound words.
• Significant priming effects of left constituents were observed only for compounds with a transparent right constituent (the head).
• Data indicate two temporally overlapping routes for auditory compound processing: direct and decompositional.

Conclusions:

• Auditory lexical access of German compounds is not solely dependent on the initial constituent.
• The transparency of the right constituent (head) plays a critical role in triggering decompositional processing.
• Prosodic features, specifically the duration of initial morphemes, influence the activation of the decompositional route.
