Area of Science:

• Developmental Psychology
• Cognitive Science
• Educational Psychology

Background:

• The relationship between phonological processing and number knowledge in early childhood is debated.
• Understanding the directionality of this influence is crucial for early intervention and education.

Purpose of the Study:

• To investigate the developmental directionality of the relationship between phonological processing and basic number knowledge in kindergarten children.
• To examine the predictive power of phonological awareness, phonological memory, and rapid automatized naming on number identification and comparison, and vice versa.

Main Methods:

• Longitudinal study tracking 82 Chinese kindergarten children from age 5 to 6.
• Assessed phonological processing (awareness, memory, naming) and number knowledge (identification, comparison) at two time points.
• Employed cross-lagged panel analyses to determine predictive relationships.

Main Results:

• Phonological awareness and number comparison demonstrated a bidirectional association.
• Early phonological awareness predicted later number identification.
• Early number comparison predicted later phonological memory.
• Rapid automatized naming did not show significant predictive relations with other variables.

Conclusions:

• The findings provide novel evidence for a bidirectional link between phonological awareness and number comparison in early development.
• Basic number knowledge appears to predict later phonological processing skills in young children, challenging previous assumptions.
• These insights have implications for designing targeted educational strategies to support both cognitive domains.
