Subclaims¶

q3 i? A multivariate linear regression using eight predictors from the detection and motor variability tasks yielded non-significant predictor coefficients for all eight visuomotor adaptation outcomes. → Inmaculada Márquez & Mario Treviño 2025 q3 i? Pairwise correlations between detection performance and visuomotor responses, and between motor variability and visuomotor performance, were weak (below ±0.15 and r < ±0.01 respectively). → Inmaculada Márquez & Mario Treviño 2025 (2)

q3 · i? · associational · r2

Within-subject multivariate linear regression in 54 participants who completed all three tasks, predicting eight adaptation indices from eight predictors, with Benjamini–Hochberg FDR correction across 72 predictor–outcome combinations. Only one significant intercept emerged; the result "suggests weak cross-task pre- dictive power".

"However, all predictor coefficients were non-significant (white bars), indicating that individual differences in detection performance and motor variability did not reliably explain var- iation in visuomotor adaptation."

q3 · i? · causal · r2

Pairwise correlations between matching detection and visuomotor discrepancy types in the same participants revealed "weak associations"; motor variability showed negligible correlation with visuomotor performance (average Pearson's r < ±0.01).

"These analyses revealed weak associations, with average Pearson correlation coefficients below ±0.15 (Supplementary Table 2)."

Discussion¶

Learner Variables¶

• Sensory Integration — predictor: learners who differ on it differ in outcomes
