Article use in Spanish-speaking children with specific language impairment

Area of Science:

• Linguistics
• Developmental Psychology
• Speech-Language Pathology

Background:

• Specific language impairment (SLI) affects language acquisition in children.
• Children learning English as a second language (ESL) may face challenges with grammatical structures like articles.
• The Surface Hypothesis posits that language impairments are related to the processing of surface phonetic forms.

Purpose of the Study:

• To analyze article usage in Spanish-speaking children with SLI learning English.
• To evaluate the applicability of the Surface Hypothesis to article errors in this population.
• To identify patterns and types of article errors made by children with SLI.

Main Methods:

• Collected language samples from 15 Spanish-speaking children with SLI and 15 with typical language development (ages 5-7).
• Matched participants by age, gender, and school.
• Analyzed the percentage of article errors using nonparametric analysis and ANCOVA, with mean length of terminable unit (MLTU) as a covariate.

Main Results:

• Significant differences in article error percentages were found between children with SLI and typically developing children, even after controlling for MLTU.
• Most errors involved omissions and gender agreement substitutions.
• Article errors were more frequent in unstressed definite articles, aligning with predictions of the Surface Hypothesis.

Conclusions:

• Children with SLI learning English exhibit distinct patterns of article errors.
• The findings support the Surface Hypothesis, suggesting that perceptual and prosodic factors play a role in the production of articles.
• This research provides insights into the linguistic challenges faced by bilingual children with SLI.
