The facilitative learning effect in implicit MSL depends on the amount of previous training: after only one prior session, the Compatible group did not outperform the New group and no novel-transition integration advantage emerged.¶

Subclaims¶

q3 i? In experiment 2 (one prior training session), performance for novel and learned transitions showed no significant differences between Compatible, Incompatible, New, and Same groups at the start or end of session 2. → Susanne Dyck & Christian Klaes 2025 q3 i? The advantage over the New group seen in experiment 1 for both Compatible and Incompatible groups held in experiment 2 only for the Incompatible group. → Susanne Dyck & Christian Klaes 2025 (2)

q3 · i? · causal · r2

Learned- and novel-transition comparisons in experiment 2 (2-day design): "no significant differences at the start or end of session 2" across Compatible, Incompatible, New, and Same groups. No effect size printed; equivalence was not tested.

"Overall, the performance for novel transitions in the Compatible, Incompatible, and New groups and the performance for learned transitions in the Compatible, Incompatible, and Same groups showed no significant differences at the start or end of session 2."

q3 · i? · causal · r2

Authors' summary in the Discussion contrasting the two experiments: the better-than-New performance appeared for both Compatible and Incompatible groups in experiment 1 but "only the case for the Incompatible group" in experiment 2. No effect size printed.

"However, at least in experiment 1 (3 days of prior training), the performance in the Compatible and Incompatible groups was signific a n t l yb e t t e rt h a nt h ep e r f o r m a n c ei nt h eN e w group. In experiment 2, this was only the case for the Incompatible group."

Related Claims¶

• After three prior training sessions, implicit learning of sequences compatible in movement transitions (both Compatible and Incompatible groups) is faster than learning a completely new sequence in experiment 1. — related
• By the end of the final training session, Compatible and Incompatible groups reach the performance level of the Same group, whereas the New group does not, in both experiments. — related
• In implicit motor sequence learning, sequence-specific performance shows a significant timepoint-by-group interaction in both a 4-day and a 2-day training design. — related
• Switching from a trained implicit motor sequence to a new, compatible, or incompatible sequence significantly reduces sequence-specific performance compared with continuing the same sequence, in both experiments. — related
