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.
q2 i? Passages containing targets in high-variability contexts were studied significantly longer (24.24 s vs 22.57 s on average). → Johns 2016

q2 · i? · causal · r2
A post-hoc analysis, conducted at a reviewer's request, used timing data reconstructed from experiment log files, recoverable for the majority of participants. "their high variability counterparts were stud- ied 1.67 s longer"; no standardized effect size printed.
"It revealed that whereas low variability passages were studied for an av- erage of 22.57 s, their high variability counterparts were stud- ied 1.67 s longer (24.24 s), a significant difference [t(52) = 4.634, p < 0.001]."
Discussion¶
Related Claims¶
- Longer exposure time (9 sec vs 3 sec per word) improves free recall, with no arousal-by-exposure interaction — related
- Diverse and uniform training contexts dissociate: processing ease and semantic representation diverge early in learning
- High-density text takes longer to complete than low-density text in self-paced lessons
- Comprehension ratings diverge across training conditions over repeated passages, with a significant condition-by-trial interaction
- Uniform (redundant) contexts yield higher semantic similarity ratings than diverse contexts
