前言 据认为,眼重力参照水平的感知是由视觉排列的方位和观察者躯体的俯仰方位共同决定的。本研究是要正式地以视觉和躯体俯仰方位的多重组合,在一个扩大了的研究范围检验这一论断。方法 将10名受试者各别固定在一个围在房间(俯仰房)中的Circolectrie床上,房间的墙壁可相对于重力倾斜不同的角度。该房间的床和墙可调整到相对于重力垂直线 It is believed that the perception of the level of reference to the eye’s gravity is determined by the combination of the orientation of the vision and the orientation of the observer’s body. This study is intended to test this assertion formally with multiple combinations of visual and body pitch orientations within an expanded study area. Methods Ten subjects were individually mounted on a Circolectrie bed enclosed in a room (pitch room) with the walls of the room tilted at different angles relative to gravity. The bed and walls of the room can be adjusted vertically to the gravitational line
