Embedded NP error in German object relative clause comprehension: A case for a universal developmental pathway

Area of Science:

• Psycholinguistics
• Developmental Psychology
• Linguistics

Background:

• Children's language acquisition involves understanding complex sentence structures.
• Relative clauses (RCs) pose a challenge, particularly object relative clauses (ORCs).
• Morphological cues can aid syntactic processing in language development.

Purpose of the Study:

• To investigate German children's comprehension of subject relative clauses (SRCs) and object relative clauses (ORCs).
• To examine how children use morphological information to process RCs.
• To analyze eye movement patterns during RC comprehension.

Main Methods:

• Eye-tracking study with German children.
• Presentation of morphologically unambiguous SRCs and ORCs.
• Visual world paradigm with character selection task.
• Analysis of fixation probabilities and response accuracy.

Main Results:

• Thematic reversal errors were the dominant error type.
• A subject advantage was observed in eye-tracking data, though temporarily overridden.
• Children showed increased fixation on the embedded noun phrase (NP) in ORCs, indicating later processing.
• Children were less efficient using early morphological cues for ORCs but used later NP morphology.

Conclusions:

• German children exhibit a subject advantage in relative clause processing.
• Processing object relative clauses (ORCs) is challenging, with delayed structural analysis.
• Children utilize embedded noun phrase (NP) morphology to update syntactic analysis during sentence comprehension.
