, 1994 ; Norouzi et al., 2018 ). With respect to darts, Vickers et al. ( 2000 ) have demonstrated a direct link between the ability to maintain visual fixation on a distant target and the degree of motor accuracy. Specifically, playing darts appears to involve different forms of visuomotor control

This study set out to determine whether the fastest online hand movement corrections are only responses to changing judgments of the targets’ position or whether they are also influenced by the apparent target motion. Introducing a gap between when a target disappears and when it reappears at a new position in a double-step paradigm disrupts the apparent motion, so we examined the influence of such a gap on the intensity of the response. We found that responses to target perturbations with disrupted apparent motion were less vigorous. The response latency was 10 ms shorter when there was a gap, which might be related to the gap effect that has previously been described for initiating eye and hand movements.

Rhythmic limb movements are often anchored at particular points in the movement cycle. Anchoring may reveal essential task-specific information for motor control. We examined the effect of tracking mode (in-phase, antiphase) and gaze direction (left, right) on anchoring in visuomotor tracking with and without concurrent visual feedback of the hand movement. For in-phase tracking, anchoring was observed at the foveated reversal point whereas for antiphase tracking anchoring was observed at both reversals, suggesting the presence of two reference points instead of one. Anchoring at the foveated reversal reflected gaze anchoring (i.e., coalignment of hand and gaze) while anchoring at the nonfoveated reversal reflected visuomotor synchronization (i.e., the hand was steered to the nonfoveated reversal coincident with a target reversal at the point of gaze). We propose that the number and location of anchor points play a crucial role in the underlying control by providing reference values for error correction processes.

The young adults reduced their attentive control and tended to simplify their visuomotor control during force tracking due to the false impression of task success with ER feedback ( Hwang et al., 2017 ; Chen et al., 2017b ).
