Paper-based reading yields better comprehension than digital-based reading. The advantage of paper has actually increased over the years since 2000 – as screens get better, the gap gets wider.

Publication Type
Meta-analysis published in Educational Research Review (also referenced earlier but expanded here with additional context)
What They Studied
Valencia University researchers conducted a comprehensive meta-analysis of 54 studies examining reading comprehension differences between paper and digital media. The analysis investigated not just whether there was a difference, but whether that difference had changed over time as digital reading technology improved and people became more familiar with screens.
Key Findings
- “Paper-based reading yields better comprehension outcomes than digital-based reading”
- “The advantage of paper-based comprehension has increased over the years since 2000”
- This finding is counterintuitive and particularly important: as screens have improved technologically and readers have become more experienced with digital reading, the paper advantage has grown rather than shrunk
- The meta-analysis provides the most comprehensive statistical synthesis of reading comprehension research available
- 54 studies represent thousands of participants across diverse contexts
- The time trend is crucial – it refutes the argument that screen disadvantages will disappear as technology improves or as “digital natives” replace older readers
- If anything, the data suggests the opposite: more sophisticated screens and more experienced screen readers still show larger comprehension gaps
- The finding held true across different types of texts, different measures of comprehension, and different digital formats
- This suggests the issue is not technological limitations but something fundamental about how we cognitively process text on screens versus paper
