Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? In Study 2 (960-word carbon-cycle text, 0%–50% SD amounts), the greater the SD amount, the worse the recall of the learning material, with each 1% more SDs worsening recall by 0.33% of the maximum achievable score. → Lukas Wesenberg 2026

q3 · i? · causal · r2
Replication regression with 101 students assigned to five conditions (0%, 12.5%, 25%, 37.5%, 50% SD amount) using a 960-word text; the recall model was significant, F(5, 95) = 5.93, p <.001, R² = 0.24, and "With 1% more SDs, the recall score worsens by 0.33%".
"the SD amount significantly affected learning performance as measured by recall, b = −0.33, p =.005. The greater the SD amount, the worse the recall of the learning material (see Fig. 5 for a line chart). With 1% more SDs, the recall score worsens by 0.33% of the maximum achievable score."
Discussion¶
Related Claims¶
- Seductive detail amount did not increase learners' intrinsic motivation in either study
- In Study 1, a greater seductive detail amount linearly worsened recall performance (b = −0.11, p = .030) — related
- Interesting but irrelevant details can impair comprehension and transfer, with effects that vary with the material and the learner — a broader claim this one bears on
- Adding seductive details to multimedia instruction significantly worsens recall of pertinent content compared with instruction without seductive details — a broader claim this one bears on
- Low-WMC readers recall fewer correct causes when text contains seductive illustrations compared with nonillustrated text — related
- Working memory capacity interacts with illustration type: seductive illustrations impair comprehension only for low-WMC readers — related
