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 differed between structure groups (Kruskal-Wallis X²(3, 533) = 25.305, p < 0.001), with SAME A and PARSING groups higher than the TRANSITION group. → B. P. Johnson 2023
q2 i? Micro-offline gains from end of skill A to onset of skill B were largest with continued practice of skill A, exceeding the TRANSITION and O+T groups. → B. P. Johnson 2023 (2)

q2 · i? · causal · r2
Experiment 3 (n = 537) randomly assigned one trial of skill A followed by four skill B variants sharing parsing rule, transition, ordinal+transition structure, or identity. "higher in the SAME A and PARSING RULE than in the TRANSITION group (both p < 0.001; FWE-corrected)".
"Performance at the onset of skill B was signi ficantly different between groups (Kruskal-Wallis test: X2 (3, 533) = 25.305, p < 0.001; Fig. 3c), higher in the SAME A and PARSING RULE than in the TRANSITION group (both p < 0.001; FWE-corrected)."

q2 · i? · causal · r2
Same Experiment 3 design; the SAME A group's micro-offline gains exceeded the TRANSITION group (p < 0.001) and the O+T group (p = 0.050), both FWE-corrected, indicating shared transition or ordinal structure did not support comparable rapid generalization.
"Further, micro-of fline gains with continued practice of skill A were larger than those identi fied when skill B shared only transition or both ordinal and transition information with skill A (SAMEA vs TRANSITION, p < 0.001; SAMEA vs O + T, p = 0.050; both FWE-corrected)"
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
- One-trial generalization of parsing rule structure exceeds sensorimotor mapping benefits: onset of skill B is approximately 19% larger in the PARSING RULE than the RANDOM group — 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
