Visual feedback is a crucial factor to motor function, and a few parameters, such as gain, delay and frequency, can influence the motor output. Here presented a behavioral study on the effect of visual feedback gain to movement by measuring the grasp force output under different visual feedback gain. Two force track tasks with different increasing/decreasing force rate have been designed, and 12 participants have been recruited in this experiment. Force deviation and error rate produced by participants have been detected under different gains. The statistical analysis revealed that gain of visual stimuli can influence force output significantly. For the same force track task, visual feedback with high gain can enhance the regulation of force production. The results suggested that different visual feedback gains may recruit different cortex function area to execute different motor tasks.
