Syntactic features in reanalysis: positive and negative symptoms.

Area of Science:

• Psycholinguistics
• Computational Linguistics
• Syntax

Background:

• Garden-path sentences pose processing challenges due to initial misanalyses.
• Ambiguous sentences require effective reanalysis mechanisms for comprehension.
• Linguistic features like Case and number play crucial roles in sentence parsing.

Purpose of the Study:

• To compare the effectiveness of Case versus number conflicts in guiding garden-path reanalysis in German.
• To investigate how different grammatical features influence sentence processing and error detection.
• To test the predictions of the Diagnosis Model of garden-path processing.

Main Methods:

• A speeded grammaticality judgment task was employed with German wh-sentences.
• Participants judged the grammaticality of sentences with Case or number mismatches.
• Comprehension questions assessed final understanding of ambiguous sentences.

Main Results:

• Case conflicts led to faster and more frequent acceptance of disambiguated sentences compared to number conflicts.
• Ungrammatical sentences with Case mismatches produced more false positive judgments than those with number mismatches.
• Both types of conflicts were eventually understood correctly, indicating successful reanalysis.

Conclusions:

• Case conflicts are more effective cues for garden-path reanalysis than number conflicts.
• The Diagnosis Model explains this difference: Case acts as a positive symptom guiding repair, while number is a negative symptom.
• The transparency of reanalysis repair influences acceptance rates of ungrammatical sentences.
