To explore the effect of long-term simulated weightlessness on the judgment of motion direction, the −6° head-down bed rest (HDBR) was used to simulate the effect of long-term weightlessness, and the judgment task of motion direction was performed on the four main directions: upward, downward, leftward, and rightward. Twenty-five males were tested on the 2nd, 8th, and 13th days of the −6° HDBR position, as well as pre-test and post-tests in the supine position. The results show that the upward direction judgment deviation was minimal over time, while the downward direction judgment deviation decreased substantially in the first test of HDBR compared to the pre-test, narrowing the judgment gap between the downward and upward direction. Long-term simulated weightlessness had a great influence on the judgment of downward direction in the initial stage, which showed better performance, and the performance tends to be stable along time increased.
