Impact of dialect use on a basic component of learning to read

Area of Science:

• Linguistics
• Developmental Psychology
• Education

Background:

• Reading achievement gaps persist between Black and White children.
• Many African American children speak a dialect distinct from the standard school dialect.
• Dialectal differences may influence early reading development and decoding skills.

Purpose of the Study:

• To investigate the impact of dialectal variations on reading decoding abilities.
• To explore the mechanisms behind how African American English (AAE) affects reading acquisition.
• To understand the role of language background in the Black-White reading achievement gap.

Main Methods:

• Behavioral assessments of reading aloud with varying pronunciations.
• Computational modeling to simulate reading acquisition processes.
• Analysis of the relationship between dialect use and decoding performance.

Main Results:

• Use of alternative pronunciations, particularly African American English (AAE), negatively affects reading aloud in developing readers.
• The impact on reading aloud is more pronounced in children with higher AAE usage.
• Dialectal differences increase the complexity of decoding tasks for children.

Conclusions:

• Differences in language background contribute to reading difficulties for some African American children.
• The complexity of learning to decode is heightened when home and school dialects diverge.
• Addressing dialectal differences is crucial for mitigating reading achievement gaps.
