Decoding digital reading: a network meta-analysis of comprehension across devices
Leveraging AI for Enhanced Educational Research Insights
Reading from digital devices is widespread, yet previous analyses suggested better comprehension on paper. This network meta-analysis investigates how various digital devices (computers, tablets, e-readers, smartphones) compare to each other and to paper in terms of reading comprehension outcomes, specifically examining the impact of scrolling. Our findings rank paper as most effective, followed by tablets, e-readers, computers, and smartphones, with scrolling significantly impacting digital comprehension. These insights are crucial for informing digital device selection in educational settings.

Overall Device Comparison
This section details how various digital reading devices compare against each other and against paper in terms of reading comprehension, providing a foundational understanding of device effectiveness.
Paper's Overall Comprehension Advantage
0 Paper ranked highest for reading comprehension across all comparisons.The network meta-analysis consistently ranked paper as the most effective medium for reading comprehension, with a P-score of 0.97. This highlights a robust advantage for traditional print over digital formats in a general context.

Scrolling Impact
This section critically examines how the necessity of scrolling influences reading comprehension across various digital devices, a key moderator identified in the analysis.
Hedges' g for Digital vs. Paper (with Scrolling)
0 When scrolling is necessary, paper is significantly better than computers.When scrolling was required, comprehension from computers was reliably lower than from paper (Hedges' g = 0.35, p < 0.001). This effect size highlights the substantial negative impact of scrolling on reading efficacy on desktop devices.
No Reliable Difference with Pagination (Hedges' g)
0 When scrolling is not needed, tablets perform similarly to paper.Conversely, when scrolling was not necessary, there were no reliable differences between paper and any digital device. Reading from a tablet without scrolling yielded an effect size of Hedges' g = 0.03, ranking it best among digital devices in this condition, suggesting that pagination mitigates the digital disadvantage.

Theoretical Frameworks
This section explores the underlying psychological and cognitive theories that explain the observed differences in reading comprehension across various mediums and scrolling conditions.
Cognitive Load Theory and Digital Reading
Cognitive load theory posits that humans have limited cognitive resources. Reading from screens, especially with scrolling, introduces extraneous cognitive load (e.g., visual strain, tracking text movement) that is irrelevant to comprehending the text. This diverts resources from intrinsic cognitive load (processing text meaning), leading to reduced comprehension. For example, smaller screens or continuous vertical scrolling increase the effort needed to track information, thereby increasing extraneous load and diminishing available resources for deep comprehension.
Construction-Integration Model & "Place on the Page"
The construction-integration model suggests readers build mental representations of text, including surface structure (words, syntax) and textbase (connected ideas). A key part of surface structure memory is "place on the page"—the physical location of information. Scrolling disrupts this spatial cue, making it harder to track previously read text and make connections. This difficulty can impede the construction of a robust textbase and situation model, especially for readers with less background knowledge who rely more on spatial cues.
Metacognitive Deficit Hypothesis & Overconfidence
The metacognitive deficit hypothesis explains that readers are often overconfident in their comprehension when reading from screens, compared to paper. This overconfidence can lead to less effective self-regulation strategies (e.g., re-reading, self-testing), ultimately hurting comprehension. Smartphones, often associated with quick, superficial tasks, may exacerbate this overconfidence, further contributing to poorer comprehension outcomes compared to more focused devices or paper.

Network Meta-Analysis (NMA) Approach
A network meta-analysis using the "netmeta" R package was conducted, allowing for direct and indirect comparisons across five conditions: paper, computers, tablets, e-readers, and smartphones. Hedges' g was used as the effect size, correcting for sample size biases. This approach allowed for a more precise ranking of device effectiveness for reading comprehension, addressing limitations of traditional pairwise meta-analyses in comparing multiple conditions simultaneously. Net splitting was used to confirm consistency in the network, with no reliable inconsistencies detected.
