Effects of clausal structure on subject-verb agreement errors

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Linguistics

Background:

• Subject-verb agreement errors occur in complex sentences.
• Previous research suggests syntactic distance influences error rates.
• The role of syntactic vs. temporal distance requires further investigation.

Purpose of the Study:

• To investigate whether the distance effect on subject-verb agreement errors is purely syntactic.
• To differentiate between syntactic and temporal distance effects in sentence processing.

Main Methods:

• Utilized a sentence completion task (Bock & Miller, 1991).
• Compared error incidence in sentences with varying syntactic structures but similar semantic content.
• Manipulated the position of a number-mismatching noun within a modifier relative to the head noun.

Main Results:

• No significant difference in subject-verb agreement error rates was found between the two syntactic conditions.
• The syntactic distance between the head noun and a number-mismatching noun did not impact error incidence.
• Findings suggest temporal distance, not syntactic distance, influences error rates.

Conclusions:

• The observed distance effect in subject-verb agreement errors is likely driven by temporal factors, not syntactic ones.
• This challenges purely syntactic accounts of agreement errors in complex subjects.
• Future research should explore the cognitive mechanisms underlying temporal distance effects in language production.
