Subclaims¶

q2 i? Item complexity interacted with picture function in a 3×3 within-subjects design, with informational pictures reducing accuracy on low-difficulty problems but supporting understanding of more complex tasks. → Schewior 2024

q2 · i? · review · r3

Wang et al.'s (2022) 3×3 within-subjects design combining three picture types with items of varying difficulty found an interaction between item complexity and picture function, suggesting IPs may reduce accuracy on easy items but support understanding of complex ones.

"The authors report that the item complexity interacted with the picture function"

Related Claims¶

• Judgments of learning are higher for easy than difficult items at all ages and increase with age, confirming the difficulty manipulation aligned with subjective difficulty — related
• Participants rated the complex three-population scenario as more difficult than the simple one-population scenario — related
• Delayed perceived task difficulty ratings relate more strongly to the relative difficulty of the more demanding items within a task set, consistent with delayed ratings being affected by the most demanding item — related
