q2 · i? · causal · r2

Across Experiment 1's randomized practice-duration groups (1, 2, 5, or 12 trials of skill A, n = 551), the article reports "no impact on parsing rule structure generalization"; performance at the onset of skill B was comparable across groups.

"Manipulating the initial practice exposure to skill A (1 to 12 trials) and inter-practice rest interval (0 –30 s) between skills A and B had no impact on parsing rule structure generalization."

Discussion¶

Related Claims¶

• 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
• 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
• Varying the inter-skill rest interval from 0 to 30 seconds does not modify one-trial generalization from skill A to skill B — related
