Subclaims¶

q3 i? In a joystick interception task, corrected inter-dot distance responses scaled steeply with angular discrepancy magnitude while user velocity changed minimally, with vU* slopes only a small fraction of IDD* slopes. → Inmaculada Márquez & Mario Treviño 2025 q3 i? Speed discrepancies engaged velocity-based adjustments rather than spatial trajectory corrections, with vU* responses strongly graded and IDD* responses non-significant. → Inmaculada Márquez & Mario Treviño 2025 (2)

q3 · i? · causal · r2

Time-locked analysis of full-length discrepancy trials in a joystick interception task with angular perturbations of six magnitudes, fitting regressions of IDD* amplitude and AUC on discrepancy magnitude. The article reports "steep and signi ficant slopes" with significant F statistics after FDR correction.

"Participants showed robustcompensatory changes in IDD* as a function of angular discrepancy magnitude, with steep and signi ficant slopes"

q3 · i? · causal · r2

Regression analysis of corrected user velocity (vU) and inter-dot distance (IDD) against speed-discrepancy magnitude in the interception task: vU* showed strong graded compensation while "IDD* responses to speed discrepancies were non-significant". Results replicated across truncated trials.

"These results indicate that speed discrepancies engaged velocity-based adjustments, rather than spatial trajectory corrections."

Discussion¶

Related Claims¶

• Gaze behavior shows distinct tracking modes: angular discrepancies engage both external target tracking and self-monitoring, whereas speed discrepancies engage predominantly self-referential monitoring — related
• Individual differences in sensory detection and motor variability do not reliably predict visuomotor adaptation, showing weak cross-task predictive power — related
• Detection of motion discrepancies increases with both perturbation magnitude and duration, with response times decreasing with magnitude — related
