In 3 experiments altitude control was examined as a function of texture type and forward speed. Four texture types were used: grid (rectangular grid with neutral colored cells); dot (small triangles distributed randomly on the ground surface); splay (rows of colored texture parallel to the direction of motion); and depression (rows of colored texture extending perpendicular to the direction of motion). The first 2 experiments required participants to track a constant altitude. Experiment 3 required participants to descend as low as possible without crashing. Results showed an interaction between texture type and forward speed. At low speeds, there was little difference between performance with the depression and splay textures. However, performance with the depression texture deteriorated with increasing forward speeds. Performance with the splay texture was independent of forward speed.
在3项实验中，研究了高度控制与纹理类型和前进速度之间的关系。使用了四种纹理类型：网格（由中性颜色单元格组成的矩形网格）；点状（随机分布在地面上的小三角形）；展开状（与运动方向平行的彩色纹理行）；以及凹陷状（与运动方向垂直延伸的彩色纹理行）。前两项实验要求参与者跟踪恒定高度。实验3要求参与者在不坠毁的情况下尽可能低地下降。结果表明纹理类型和前进速度之间存在交互作用。在低速时，凹陷状纹理和展开状纹理的表现差异不大。然而，凹陷状纹理的表现随着前进速度的增加而变差。展开状纹理的表现与前进速度无关。
