Postural and visual motion aftereffects may be experienced after exposure to alternating periods of free fall and increased gravitoinertial force in parabolic flight. In an aftereffect, the body feels as if it is again undergoing periodic changes in force level because of motion of the substrate; strong apparent postural motion is also accompanied by visual motion of the surroundings. The aftereffects are discussed according to a) their character, b) their time course, c) secondary symptoms associated with them, d) conditions favoring their occurrence, e) their relation to the inducing frequency, f) fragments of the complete pattern, g) their duration, and h) the importance of contact cues.
在抛物线飞行中经历自由落体和重力惯性力增加的交替阶段后，可能会出现姿势和视觉运动后效。在后效中，由于基底的运动，身体感觉好像再次经历力水平的周期性变化；强烈的明显姿势运动也伴随着周围环境的视觉运动。根据以下方面对后效进行了讨论：a）它们的特征，b）它们的时间进程，c）与它们相关的继发症状，d）有利于它们发生的条件，e）它们与诱导频率的关系，f）完整模式的片段，g）它们的持续时间，以及h）接触线索的重要性。
