Prenuclear L^∗+H Activates Alternatives for the Accented Word

Area of Science:

• Psycholinguistics
• Phonetics
• Semantics

Background:

• Prosodic marking, particularly focus, is known to activate alternative meanings in language processing.
• Contrastive topics in German are prosodically realized by prenuclear L*+H accents.
• The precise role of prenuclear accents versus nuclear accents in activating alternatives requires further investigation.

Purpose of the Study:

• To determine if prenuclear accents can activate contrastive alternatives.
• To compare the alternative activation by contrastive topics with that of focus constituents.
• To investigate whether accent type (L*+H vs. L+H*) or F0-excursion drives alternative activation.

Main Methods:

• Two visual-world eye-tracking studies were conducted with German listeners.
• Participants heard declarative utterances with contrastive topic (prenuclear L*+H) or broad focus (prenuclear L+H*) accents.
• Eye movements were monitored as participants viewed displays with contrastive alternatives, related items, and distractors.

Main Results:

• Participants fixated more on contrastive alternatives when subjects had a prenuclear L*+H accent, mirroring focus effects.
• Experiment 2, controlling for F0-excursion, confirmed the effect, though with a slightly delayed time course.
• Prenuclear L*+H accents rapidly activate alternatives online, with minimal influence from F0-excursion.

Conclusions:

• Prenuclear L*+H accents in German effectively signal contrastive topics and activate alternatives during real-time processing.
• The findings align with semantic models of focus and contrast, suggesting similar processing mechanisms.
• Accent type, rather than prominence (F0-excursion), is the primary driver for alternative activation in this context.
