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 1, the greater the amount of SD content, the worse the recall of the learning material, with each 1% more SDs worsening the recall score by 0.11% of the maximum achievable score. → Lukas Wesenberg 2026

q3 · i? · causal · r2
Online regression analysis (PROCESS Model 2) with 191 students randomly assigned to 0%, 25%, or 50% SD conditions with a 600-word solar-cell text; the overall recall model was significant, F(5, 185) = 8.41, p <.001, R² = 0.19, and "the greater the amount of SD content, the worse the recall".
"In line with H5, the SD amount significantly affected learning performance as measured by recall, b = −0.11, p =.030. The greater the amount of SD content, the worse the recall of the learning material."
Discussion¶
Related Claims¶
- Seductive detail amount did not increase learners' intrinsic motivation in either study
- In Study 2 with a longer text and five SD amounts, greater seductive detail amount again worsened recall (b = −0.33, p = .005) — related
- 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
- Seductive detail amount did not significantly affect transfer performance in Study 1 — 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
