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? Onset of skill B was significantly higher in PARSING, SAME A, and SAME B groups than the RANDOM group, and PARSING exceeded RANDOM by about 19% (t(250) = 3.577, p < 0.001). → B. P. Johnson 2023
q2 i? Micro-offline gains in the PARSING RULE group were 46% and 81% of those in the SAME A and SAME B groups. → B. P. Johnson 2023 (2)

q2 · i? · causal · r2
Experiment 4 (n = 212 additional participants) added a RANDOM group typing random keypresses for one trial before skill B, isolating sensorimotor mapping. The parsing-cue contribution exceeded mapping: "approximately 19% larger in the PARSING RULE than in the RANDOM group (Independent-samples t-test: t (250) = 3.577, p < 0.001".
"Performance at the onset of skill B was approximately 19% larger in the PARSING RULE than in the RANDOM group (Independent-samples t-test: t (250) = 3.577, p < 0.001; Fig. 4c)"

q2 · i? · causal · r2
Combined analysis of Experiment 4 groups with Experiment 3 data; PARSING RULE micro-offline gains were "46% and 81% of those observed in the SAME A and SAME B groups", which the authors describe as highlighting substantial variation in generalization tied to skill structure.
"Micro-of fline gains from the end of the first skill to the onset of the second ( GenB0 /C0 Af ) in the PARSING RULE group represented 46% and 81% of those observed in the SAME A and SAME B groups"
Discussion¶
Related Claims¶
- A single 10-second practice trial of motor skill A produces micro-offline generalization, with performance at the onset of skill B exceeding the end of skill A — related
- Early generalization is content-specific: skill B onset performance is higher when skills share a parsing rule than when they share only transition structure — related
- Increasing initial practice of skill A from 1 to 12 trials does not change parsing-rule generalization to skill B in early learning — related
