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? Training time and the GROUP×BTT time interaction had significant effects on performance of the complex task variants. → Hehl 2026

Hehl, M., Toyonaga, T., Carson, R. E., Dupont, P., Van Laere, K., Swinnen, S. P. & Cuypers, K. (2026). No significant changes in synaptic density and gray matter volume following motor learning—a pilot study. npj Science of Learning. https://doi.org/10.1038/s41539-026-00451-5
q3 · i? · causal · r1
Linear mixed model on complex-subtask progress-test scores in the 22-participant pilot. Group comparisons showed differences for the last two progress tests (PT5: p = 0.0014; PT6: p = 0.0024), and "each training group showed significant improvements for each pair of subsequent progress tests".
"the time spent on the BTT (β = 0.0617, SE = 0.0043, df = 110, t = 14.485, p < 0.0001) and the interaction GROUP×BTT time (β = 0.0259, SE = 0.0060, df = 110, t = 4.309, p < 0.0001) had a significant effect on task performance of complex task variants"
Discussion¶
Related Claims¶
- Four weeks of bimanual tracking training significantly improves 1:1 subtask performance with training time, with no group effect on the 1:1 task — related
- Learning progress (linear slope of progress-test scores) differs significantly between simple and complex training groups for complex subtasks but not the 1:1 subtask — a narrower finding that bears on this claim
