Movement speed-accuracy trade-off is a function of the space-time constraints of the task. We investigated the space-time account of Hancock and Newell (1985) and the hypothesis of complementarity between the four moments of the error distribution in space and time. Twelve participants performed 15 conditions in a line drawing task composed of different spatial (10, 20, and 30 cm) and temporal (250 to 2,500 ms) criteria. The results showed that all moments of distributions changed systematically between conditions but there were some departures from the Hancock and Newell predictions. In contrast, individual analysis revealed the complementarity of the spatial and temporal error including a trade-off between the four moments of error. These findings support a complementary space-time account of movement speed and accuracy.
运动速度-准确性权衡是任务时空限制的一种函数。我们研究了汉考克和纽厄尔（1985年）的时空理论以及空间和时间误差分布四个矩之间的互补性假设。12名参与者在一个由不同空间（10厘米、20厘米和30厘米）和时间（250毫秒至2500毫秒）标准组成的线条绘制任务中完成了15种条件。结果表明，分布的所有矩在不同条件之间都有系统变化，但存在一些与汉考克和纽厄尔预测的偏差。相比之下，个体分析揭示了空间和时间误差的互补性，包括误差四个矩之间的权衡。这些发现支持了运动速度和准确性的互补时空理论。
