Uncovering productive morphosyntax in French-learning toddlers: a multidimensional methodology perspective

Area of Science:

• Linguistics
• Developmental Psychology
• Psycholinguistics

Background:

• Subject-verb agreement is a complex grammatical feature crucial for sentence structure.
• Understanding the early acquisition of morphosyntax, particularly agreement, provides insights into language development.
• Infrequent grammatical patterns pose unique challenges for language learners.

Purpose of the Study:

• To evaluate the productivity of an infrequent subject-verb agreement pattern in early French acquisition.
• To investigate the influence of input frequency, semantic transparency, and perceptual factors on agreement comprehension.
• To determine if toddlers possess abstract and productive knowledge of subject-verb agreement.

Main Methods:

• A multidimensional methodological approach was employed.
• An experimental setting utilized a pointing task with pseudo-verbs.
• Comprehension of singular vs. plural agreement was assessed in children aged 2;6.

Main Results:

• Children aged 2;6 showed significant comprehension of both singular and plural agreement.
• Comprehension was not directly correlated with input frequency or marker reliability.
• Results did not solely reflect lexically driven knowledge.

Conclusions:

• Toddlers aged 2;6 possess abstract and productive knowledge of subject-verb agreement.
• This knowledge is evident even for patterns with limited occurrence in the input.
• Comprehension is influenced by factors beyond simple frequency or semantic transparency.
