Is reading prosody related to reading comprehension? A meta-analysis

Area of Science:

• Educational Psychology
• Linguistics
• Cognitive Science

Background:

• Reading prosody, encompassing elements like intonation and phrasing, is often considered a hallmark of skilled reading.
• Its precise relationship with reading comprehension, however, requires further empirical clarification.

Purpose of the Study:

• To systematically review and meta-analyze the existing literature on the relationship between reading prosody and reading comprehension.
• To investigate potential moderating factors, including specific prosody features, student reading development (grade level), and orthographic depth.

Main Methods:

• Conducted a systematic review and meta-analysis of 35 studies involving 9,349 students across grades 1-9 and 8 languages.
• Analyzed the strength of the association between reading prosody and reading comprehension, examining variations based on prosody features, grade level, and orthographic depth.

Main Results:

• A moderate overall relation (r = .51) was found between reading prosody and reading comprehension.
• The strength of this relation varied significantly by prosody feature; rating scales showed a stronger association than pitch indicators (e.g., adult-like contour, F0 sentence-final declination).
• Neither grade level nor orthographic depth emerged as significant moderators of the prosody-comprehension link.

Conclusions:

• The relationship between reading prosody and reading comprehension is not uniform and depends on how prosody is measured.
• Future research and interventions should consider specific prosodic features, particularly those assessed via rating scales, for a more nuanced understanding and effective support of reading comprehension development.
