Subclaims¶

q3 i2 In Study 1a, participants in the text-only condition showed greater draw relative accuracy than participants in the text-with-image condition (Pearson d = 0.51; Gamma d = 0.50). → Jaeger 2024 q3 i2 In Study 2, the same pattern was marginally significant for draw relative accuracy (Pearson d = 0.56; Gamma d = 0.53), with text-only showing greater accuracy. → Jaeger 2024 (2)

Jaeger, A. J., & Fiorella, L. (2024). Metacognitive effects of instructional visuals: the role of cue use and judgment type. Metacognition and Learning. https://doi.org/10.1007/s11409-023-09370-x

q3 · i2 · causal · r2

Online experiment with 163 undergraduates reading biology texts, randomly assigned to text-only or text-with-image. Draw relative accuracy (intra-individual Pearson correlation between draw judgments and test performance) was significantly lower in the image condition, "t(147) = 3.10, p = 0.002, d = 0.51". Gamma correlations showed the same pattern (d = 0.50).

"there was a significant difference in draw relative accuracy between the two groups, with participants in the text-only condition showing greater relative accuracy than participants in the text-with-image condition, t(147) = 3.10, p = 0.002, d = 0.51."

q3 · i2 · causal · r2

Lab experiment with 48 undergraduates reading chemistry texts, randomly assigned to text-only or text-with-image. Draw relative accuracy was marginally lower in the image condition, "t(45) = 1.93, p = 0.06, d = 0.56". Gamma correlations showed a parallel marginal difference (d = 0.53).

"there was a marginal difference in draw relative accuracy between the two groups (with a medium effect size), with participants in the text-only condition showing greater relative accuracy than participants in the text-with-image condition, t(45) = 1.93, p = 0.06, d = 0.56."
