Visual feedback attenuates force fluctuations induced by a stressor

Article Abstract:

The effects of a stressor on the force fluctuations and information transmission exhibited by young, middle-aged and older adults are determined when a pinch-grip task is performed with or without visual feedback. The results indicate that removal of visual feedback increases the force fluctuation and decreases information transmission during a stressor period.
