Speech perception problems in Chinese children with reading difficulties: Insights from acoustic context effects

Area of Science:

• Cognitive psychology
• Developmental psychology
• Linguistics

Background:

• Speech sound perception is influenced by surrounding acoustic information.
• Understanding how reading difficulties affect auditory processing of context is vital for educational interventions.

Purpose of the Study:

• To investigate if Chinese children with reading difficulties can use forward and backward acoustic contexts for speech sound identification.
• To compare context effect utilization in poor readers versus typical readers.

Main Methods:

• 34 Chinese children with poor reading abilities and 34 typical readers participated.
• Tasks included forward (nonspeech, speech) and backward acoustic context effect assessments using consonant continua.
• Phoneme awareness and academic performance were measured.

Main Results:

• Poor readers showed typical forward context effects but significantly reduced backward context effects.
• Identification curves for poor readers were shallower, indicating less sensitivity to context.
• Phoneme awareness did not correlate with context effects; math ability correlated with poorer backward effects.

Conclusions:

• Children with reading difficulties effectively use general auditory processing (forward context) but struggle with phonologically mediated context effects (backward context).
• This suggests a specific deficit in phonological processing impacting speech perception in poor readers.
• Findings highlight the importance of phonological skills in auditory context processing for reading development.
