q3 i? In experiment 1 (4 days), a mixed ANOVA on sequence-specific Δ compound values revealed significant effects of timepoint, group, and their interaction. → Susanne Dyck & Christian Klaes 2025 q3 i? In experiment 2 (2 days), a mixed ANOVA on Δ compound values again revealed significant effects of timepoint, group, and their interaction. → Susanne Dyck & Christian Klaes 2025 (2)

q3 · i? · causal · r2

Mixed ANOVA in experiment 1 (4-day online bimanual SRTT, n = 71) on Δ compound values, the sequence-minus-random contrast. The article reports F = 129.568 (timepoint), F = 5.442 (group), and a "significant interaction of timepoint and group (F = 5.256, p < 0.001)". No effect size printed.

"A mixed ANOVA with the factor timepoint (within-subject) and group (between-subject) revealed as i g nifi cant effect of the factor timepoint (F = 129.568, p < 0.001), a significant effect of the factor group ( F = 5.442, p = 0.002) and a significant interaction of timepoint and group (F = 5.256, p < 0.001) on the Δ compound values."

q3 · i? · causal · r2

Mixed ANOVA in experiment 2 (2-day design; Same-group data reused from experiment 1) on Δ compound values, with F = 174.331, F = 4.918, and "a significant interaction of timepoint and group (F = 4.484, p < 0.001)". No effect size printed.

"A mixed ANOVA with the factor timepoint (within-subject) and group (between-subject) revealed a significant effect of the factor time- point ( F = 174.331, p < 0.001), a significant effect of the factor group (F = 4.918, p = 0.004) and a significant interaction of timepoint and group (F = 4.484, p < 0.001) on the Δ compound values"

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
• 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
• 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
