“…The target movement times ranged from 10 cm (fast: 250 ms, fast-middle: 300 ms, middle: 550 ms, middle accurate: 1000 ms, and accurate: 1300 ms), 20 cm (fast: 300 ms, fast-middle: 450 ms, middle: 650 ms, middle accurate: 1500 ms, and accurate: 2000 ms), and 30 cm (fast: 350 ms, fast-middle: 550 ms, middle: 750 ms, middle accurate: 1800 ms, and accurate: 2500 ms).

“…According to these findings, the characteristics and prevalence of submovements can result from different task constraints [ 19 , 22 , 24 ]. Most of the previous studies have focused on the condition that only instructed participants to move as fast as possible in a time minimization task (e.g., Fitts’ paradigm) [ 6 , 9 , 14 , 18 , 25 – 27 ].…”

“…Only a few submovement studies have instructed participants to deliberately control the duration of the criterion movement time [ 8 , 28 – 29 ]. However, the accuracy and variability of movement spatial and temporal error in movement speed and accuracy are influenced by the interaction of the movement properties of amplitude, time and the emergent average velocity [ 24 , 30 ].…”

There is preliminary evidence that there are several types of submovements in movement aiming that reflect different processes of control and can result from particular task constraints. The purpose of the study was to investigate the effect of movement space and time task criteria on the prevalence of different submovement control characteristics in discrete aiming. Twelve participants completed 3 distance x 5 time conditions each with 100 trials in a target-aiming movement task. The kinematic structure of the trajectory determined the prevalence of 5 submovement types (none; pre-peak, post-peak movement velocity; undershoot, overshoot). The findings showed that the overall number of submovements increased in the slower space-time conditions and was predominantly characterized by post-peak trajectory submovements rather than discrete overshoot submovements. Overshoot submovements were more frequent in the high average movement velocity and short time duration conditions. We concluded that there are qualitatively different distributional patterns of submovement types in discrete aiming tasks that are organized by the quantitative scaling of the average movement velocity arising from multiple control processes to meet the specific space-time task constraints.
