Table 1.
Averages of: deceleration durations and instantaneous tangential accelerations of the reaching and target index motion at the time of reaching hand movement termination (2 cm/s threshold), peak target and reaching hand speeds, and time between start of target and voluntary hand motions.
| Variable | VA | NVA | NVP |
|---|---|---|---|
| Reaching index decel. dur. (ms) | 875.7 | 952.3 | 986.7 |
| Target index decel. dur. (ms) | 609.7 | 696.2 | 646.7 |
| Reaching index decela (cm/s/s) | −58.0 | −69.3 | −70.3 |
| Target index decelb (cm/s/s) | −56.9 | −63.7 | −65.4 |
| Peak target index speed (cm/s) | 66.61 | 61.07 | 57.59 |
| Peak reaching index speed (cm/s) | 104.4 | 98.3 | 101.94 |

a
Instantaneous acceleration of reaching index at reaching index movement termination.
b
Instantaneous acceleration of target index at reaching index movement termination.
c
Time between onset of target hand motion and reaching hand motion (note reaching hand motion onset was initiated after a sound occurring randomly between 50 and 300 ms after target hand motion onset).
