Subclaims¶

q3 i2 Informed participants performed significantly worse (d = 0.72) and reported higher cognitive load during the video (d = 0.72) than uninformed participants. → de Jonge 2026

Evidence¶

de Jonge 2026¶

de Jonge, T. H. S., de Koning, B. B., & van Wermeskerken, M. (2026). It's all a matter of expectancy: How expectancies about task execution perspective influence learning through video modeling examples. Learning and Instruction, 105, 102422. https://doi.org/10.1016/j.learninstruc.2026.102422

q3 · i2 · causal · r2

Exploratory analysis of the subsample of 128 participants who performed the task from a different angle than shown; half (n = 64) were informed of the misalignment beforehand. Informed participants "performed significantly worse", d = 0.72, with higher video cognitive load, d = 0.72.

"Independent-samples t-tests revealed that those who were informed performed significantly worse than those who were not, t(126) = 4.09, p < .001, d = 0.72 (large effect, mean difference = 1.73), and reported higher cognitive load during the video, t(126) = 2.67, p = .008, d = 0.72 (medium effect, mean difference = 1.00)."

Discussion¶

Related Claims¶

• Mismatch between recording angle and expected angle increases cognitive load both during video observation and during task execution — related
• Mental rotation ability moderates the alignment benefit: higher-ability participants benefit more from recording–expected angle alignment — related
• Recording angle alone does not affect self-reported cognitive load during video observation or task execution — related
