摘要： 本实验探讨了影响深度觉及距离判断的有关因素。实验分三部分:一、双眼正视(0°)和双眼斜视(45°)条件的深度觉辨别实验;二、双眼正视(0°)条件下不同距离相对判断实验;三、双眼斜视(45°)条件下的相对距离判断实验。实验结果表明:在双眼正视条件下(0°),深度觉辨别最准确,双眼斜视(45°)条件下,误差值明显增加,而单眼正视条件下,误差值最大。双眼斜视(45°)条件下的相对距离判断的误差值明显较之双眼正视(0°)条件下的为大。对2/4的相对距离判断的准确性均较之对1/4和3/4的距离为高。在双眼斜视条件下,眼肌调节发生变化,睫状肌紧张度增加,视觉易于疲劳可能是造成深度觉及距离判断准确性降低的主要原因。

Abstract: Some factors affecting the accuracy of depth discrimination anddistance judgment were studied in this experiment. The results showedthat depth discrimination and distance judgment were found to be mostaccurate normal binocular observation at 0°. Errors increased obviouslyin binocular observation at 45°sidewise, and the largest errors occurredwhen using one eye only. To compare the accuracy of relative distancejudgments, it was found that judgment of the relative distance of 2/4 wasmore accurate than that of the 1/4 and 3/4. The coordinative movementof both eyes looking through binocular are very important factorsaffecting depth discrimination and distance judgment.
