Kinematic properties of reaching movement.

<p>(A) Average reach trajectory to the far target of each side in each condition for a single participant. Green and blue curves show trajectories when prime-mask combinations were congruent (RR and LL conditions) and incongruent (LR and RL conditions), respectively. (B) Average X velocity profile in each far-target condition for a single participant. Green and blue curves show the velocities when the prime-mask combination was congruent and incongruent, respectively. Red dashed curves denote ±1 SD of velocities between trials. The data were aligned at the button release. (C) Mean X velocity difference profiles (Solid: RL – LL. Dashed: RR – LR.) calculated from the pooled data to far and near targets. The velocity difference was calculated as the index of the response onset to the prime stimulus. The threshold value (dotted line) was set at 0.03 m/s. (D) Mean X velocity of the 100-ms-time window (calculated from the pooled data to far and near targets) corresponding to the gray area in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0034985#pone-0034985-g003" target="_blank">Fig. 3</a>B (i.e., 200∼300 ms after the prime onset) in each condition. (E) Relationship between the awareness of the association (between the participant’s own performance and the color cue) and the strength of the implicit motor control induced by the invisible stimulus. The difference of mean X velocity in the 100-ms-time window (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0034985#pone-0034985-g003" target="_blank">Fig. 3</a>D) between RL (RR) and LL (LR) conditions for each participant was calculated as the individual strength of the implicit motor control.
