Speech categorization consistency is robustly associated with receptive oral language performance.

= 95) equated the number of speech and visual continua and added a nonverbal IQ measure. Despite shared variance across domains, speech categorization consistency retained a unique association with language performance beyond visual categorization consistency and nonverbal IQ. These findings suggest that categorization consistency reflects both domain-general and speech-specific components, with speech consistency showing the most robust relationship to receptive oral language performance. This reframes individual differences in speech categorization by highlighting categorization consistency as an important dimension linking perceptual processing and broader language function.
