Adult female praying mantises, Sphodromantis lineola (Burr.), were presented with computer-generated black rectangular stimuli that moved horizontally or vertically at 82 deg/s against a homogeneous white background. Both stimulus configuration (orientation in relation to direction) and the retinal location of the stimulus image affected the rate at which mantises responded appetitively (approached or struck at the stimulus). Mantises responded most to square stimuli (12.5 deg x 12.5 deg) when they moved horizontally or vertically through, or horizontally at 24.5 deg below the center of their visual field. Mantises also responded most to vertically (vs. horizontally) oriented rectangular stimuli (12.5 deg x 47 deg) that moved through their visual-field center, irrespective of whether the stimuli moved downward or horizontally. Upward moving stimuli elicited intermediate amounts of behavior with no configuration preference. Mantises did not demonstrate a configuration preference when rectangular stimuli moved > or = 24.5 deg outside of the visual-field center. Furthermore, mantises responded very little and demonstrated no configuration preferences to stimuli that moved less than approximately 83 deg through their visual field even if the stimuli moved through the visual-field center.
向成年雌性条纹螳螂（Sphodromantis lineola (Burr.)）呈现计算机生成的黑色矩形刺激物，这些刺激物在均匀的白色背景下以82度/秒的速度水平或垂直移动。刺激配置（相对于方向的取向）和刺激图像在视网膜上的位置都会影响螳螂做出捕食性反应（接近或攻击刺激物）的速度。当方形刺激物（12.5度×12.5度）在其视野中心水平或垂直穿过，或在视野中心下方24.5度处水平移动时，螳螂对其反应最为强烈。对于穿过其视野中心的垂直（相对于水平）取向的矩形刺激物（12.5度×47度），螳螂也反应最为强烈，无论刺激物是向下还是水平移动。向上移动的刺激物引发的行为量适中，且没有配置偏好。当矩形刺激物在视野中心外移动大于或等于24.5度时，螳螂没有表现出配置偏好。此外，即使刺激物穿过视野中心，但如果其在视野中移动的角度小于约83度，螳螂对其反应非常少，且没有表现出配置偏好。
