Object agreement and specificity in early Swahili

Area of Science:

• Linguistics
• Developmental Psychology
• Language Acquisition

Background:

• Previous research on specificity in child language acquisition yielded conflicting results.
• Dutch children's omission of determiners and pronoun scrambling were linked to a lack of specificity knowledge.
• Russian children's argument placement suggested an understanding of specificity.

Purpose of the Study:

• To investigate the acquisition of object agreement and specificity in early Swahili.
• To determine if Swahili-speaking children understand the relationship between object agreement and specificity.

Main Methods:

• Analysis of naturalistic speech data from four Swahili-speaking children aged 1 year 8 months to 3 years 2 months.
• Examination of the use of object agreement in obligatory and prohibited contexts.

Main Results:

• Swahili-speaking children predominantly used object agreement in obligatory contexts (e.g., personal names, topicalization, first/second person reference).
• Object agreement was absent in prohibited contexts, such as intransitive clauses, indicating a nuanced understanding.
• Children's performance suggests they grasp the specific/non-specific distinction.

Conclusions:

• Swahili children acquire knowledge of specificity and its relation to object agreement before two years of age.
• Findings challenge theories suggesting a later acquisition of specificity based on other linguistic features.
• Early acquisition of specificity in Swahili highlights language-specific developmental pathways.
