Subclaims¶

q3 i? In experiment 1, introducing the new, compatible, or incompatible sequence at the start of session 4 significantly reduced performance relative to the end of session 3, while the Same group did not change. → Susanne Dyck & Christian Klaes 2025 q3 i? In experiment 1, the Same group was significantly higher than all other groups at the start of session 4. → Susanne Dyck & Christian Klaes 2025 (2) q3 i? In experiment 2, the Same group differed significantly from all other groups at the start of session 2. → Susanne Dyck & Christian Klaes 2025 (3)

q3 · i? · causal · r2

Within-group repeated-measures comparisons in experiment 1 (bimanual implicit SRTT). Performance "was significantly reduced compared to the end of session 3" for New, Compatible, and Incompatible groups, while the Same group did not change (p = 1.). No effect size printed.

"When the new, compatible, or incompatible sequence was introduced at the start of session 4, the performance was significantly reduced compared to the end of session 3 (p = 0.002, p < 0.001, p = 0.001, for the New, Compatible, and Incompatible group, respectively), while the performance in the Same group did not change between the end of session 3 and the start of session 4 (p =1 . ) ."

q3 · i? · causal · r2

Post hoc comparisons at the start of session 4 in experiment 1: "The performance in the Same group was significantly higher compared to all other groups (allp < 0.001)", while Compatible and Incompatible did not differ (p = 1.). No effect size printed.

"The performance in the Same group was significantly higher compared to all other groups (allp < 0.001). Only the Compatible and Incompatible groups showed no difference in performance (p = 1.)."

q3 · i? · causal · r2

Post hoc comparisons at the start of session 2 in experiment 2: "a significant difference in Δ compound values between the Same and all other experimental groups (all p ≤ 0.001)". No effect size printed.

"Post-hoc tests showed a significant difference in Δ compound values between the Same and all other experimental groups (all p ≤ 0.001)."

Discussion¶

Related Claims¶

• In experiment 1, novel movement transitions were performed better in the Compatible and Incompatible groups than in the New group, while initially learned transitions were retained better in the Same group. — 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
• 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
• 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. — 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
• Compatible and Incompatible groups performed comparably across learning, indicating that the basis of compatibility in implicit MSL is shared movement transitions rather than ordinal positions. — related
