This study was designed to analyze the effects of physical or perceptual work loads on a coincidence/anticipation task. Three experimental treatments were applied: (1) a physical work load, (2) a perceptual work load, and (3) a combination of the physical and the perceptual work loads. The dependent variable was performance on a coincidence/anticipation task, a throw at a moving target. Time errors and accuracy scores were recorded. The type of work load does not affect any of the dependent variables. However, all types of work load generated definite improvement pre- and posttest for the temporal constant error; better performance, as measured by constant error, was recorded for all subjects when the speed of the apparent movement being intercepted was 4.7 km/hr. Temporal variability was reduced in the subject performance at 8.1 km/hr.
本研究旨在分析体力或感知工作负荷对一项同步/预判任务的影响。采用了三种实验处理方式：(1) 体力工作负荷，(2) 感知工作负荷，以及(3) 体力和感知工作负荷的组合。因变量是同步/预判任务的表现，即向移动目标投掷。记录了时间误差和准确性得分。工作负荷类型对任何因变量均无影响。然而，所有类型的工作负荷在测试前和测试后都使时间常数误差有了明显改善；当被拦截的表观运动速度为4.7千米/小时时，所有受试者以常数误差衡量的表现都更好。在8.1千米/小时时，受试者表现中的时间变异性降低了。
