Subclaims¶

q3 i? Time spent on the bimanual tracking task had a significant effect on 1:1 task performance, but GROUP and the GROUP×BTT time interaction did not. → Hehl 2026

q3 · i? · causal · r1

Linear mixed model on progress-test scores of the 1:1 subtask in the 22-participant pilot, with SUBJECT as random effect and GROUP and BTT time as fixed effects. The article reports "a significant effect on task performance on the 1:1 task" of training time, with no group effect (p = 0.9671).

"The time spent on the BTT training paradigm (β = 8.1053, SE = 0.6741, df = 110, t = 12.023, p < 0.0001) had a significant effect on task performance on the 1:1 task, but not GROUP ( p = 0.9671)"

Discussion¶

Related Claims¶

• On complex subtasks, both training time and the group-by-time interaction significantly predict performance, with the complex group better at later progress tests — 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 — related
