Object attraction effects during subject-verb agreement in Persian

Area of Science:

• Psycholinguistics
• Linguistic Theory
• Cognitive Science

Background:

• Subject-verb agreement reveals interactions between grammar and semantics in sentence production.
• Attraction errors occur when local nouns, grammatically part of the subject, interfere with agreement.
• Existing theories include control-based and competition-based models.

Purpose of the Study:

• To test the competition-based hypothesis in sentence production.
• To investigate if intervening object nouns, outside the subject-verb relationship, cause attraction effects in Persian.
• To examine the role of object plural markers in agreement attraction.

Main Methods:

• Utilized a subject-object-verb language (Persian) with optional subject-verb agreement.
• Designed experiments that did not require participants to make grammatical errors.
• Analyzed agreement patterns influenced by intervening objects.

Main Results:

• Object nouns were found to act as attractors for subject-verb agreement.
• The attraction effect was dependent on the specific type of plural marker on the object noun.
• Demonstrated that attractors outside the direct subject-verb syntactic relationship can influence agreement.

Conclusions:

• Results support competition-based theories of agreement production.
• Agreement can be influenced by elements not strictly within the subject-verb scope.
• Highlights the complex interplay of syntactic and semantic factors in language production.
