摘要: This investigation tested the proposal that a "highly accurate" and temporally unstable stored target representation is available to motor system for online control of memory-guided reaches. Participants reached was: (a) visible during response, (b) extinguished at movement onset, (c) occluded 0, 500, 1,500 2,500 ms in advance response cueing. Additionally, trials were performed with (i.e., limb visible) without occluded) vision reaching limb. Results showed undershot location each condition, characterized by primarily offline mode control. In contrast, consistent level endpoint accuracy condition elicited more corrections than trials. It therefore proposed reasonably accurate stable can be combined moving
