Original and redefined task periods. Speed profiles (black) and distance from cursor to target (yellow) are shown for two example trials: one that included an IR (a, c) and one where there was no IR because the hand was already at the initial target at the beginning of the trial (b, d). In the original task periods (a, b), Hold typically started while hand speed was still high because the monkeys had a habit of allowing the hand to enter the target at high speed because the target region was large enough to allow slowing down within the region without overshooting it. The redefined periods (a, b) were aligned to the speed profiles, capturing the high-speed movements within the Reach periods and leaving only low speed for Hold periods.
