The Beat to Read: A Cross-Lingual Link between Rhythmic Regularity Perception and Reading Skill

Area of Science:

• Cognitive Science
• Linguistics
• Auditory Neuroscience

Background:

• Auditory rhythm cognition and language skills are hypothesized to share underlying cognitive resources.
• Previous research suggests a link between musical rhythm and language processing.
• The specific relationship between regularity perception and language proficiency requires further investigation.

Purpose of the Study:

• To investigate the correlation between auditory regularity perception and language skill.
• To determine if this relationship is specific to regularity detection versus irregularity detection.
• To assess the robustness of the regularity-language link when controlling for other factors.

Main Methods:

• 26 adult participants, native speakers of 11 languages, completed auditory rhythm perception tasks (regularity and irregularity detection).
• Language skill was measured using rapid automatized naming (RAN).
• Statistical analyses (Spearman's rho, partial correlations) were used to assess relationships, controlling for non-verbal IQ and musical expertise.

Main Results:

• A significant negative correlation was found between regularity detection and RAN (rho = -0.47, p < 0.01).
• No robust correlation was observed between irregularity detection and RAN.
• The correlation between regularity detection and RAN remained significant after controlling for irregularity detection, non-verbal IQ, and musical expertise.

Conclusions:

• Rhythmic regularity detection is a key component of auditory rhythm cognition that significantly relates to language skill.
• This relationship supports the 'shared resources model' linking rhythm, language, and music.
• The findings highlight a universal connection between rhythmic regularity perception and reading skill, independent of intelligence and musicality.
