Trajectories of arm movement during a pointing task were shown to be unaffected by large loads. Moreover, when the effective arm length was changed, the target was still approached along a direct trajectory. It is concluded that: (1) compensation for load occurs automatically without affecting those constraints on the basis of which movements are organized; (2) that the effective lengths of body segments as well as joint angles constitute variables utilized in the organization of trajectories.
在指向任务中，手臂运动轨迹被证明不受大负荷的影响。此外，当有效手臂长度改变时，目标仍会沿着直接轨迹靠近。得出以下结论：(1) 负荷补偿会自动发生，而不会影响运动组织所依据的那些约束条件；(2) 身体节段的有效长度以及关节角度构成了用于轨迹组织的变量。
