A noise masking paradigm was used to measure spatial tuning for the deviating and nondeviating eyes of two esotropic cats and for one eye of a control cat. With increasing noise contrast, masking grew more slowly for both the deviating and the nondeviating eyes of the esotropic cats than for the control cat; apparently, contrast coding is impaired for both eyes of the esotropic cats. Masking with band-reject filtered noise indicated that detection channels for either eye of the esotropic cats were twice as broadly tuned as those for the control cat. In a subsequent experiment, the spatial tuning characteristics of two human esotropes were found to be normal, indicating a fundamental difference between human esotropia and esotropia induced in cats by the section of an eye muscle.
采用噪声掩蔽范式来测量两只内斜视猫的偏斜眼和非偏斜眼以及一只对照猫的一只眼睛的空间调谐。随着噪声对比度的增加，内斜视猫的偏斜眼和非偏斜眼的掩蔽增长速度均比对照猫慢；显然，内斜视猫的两只眼睛的对比度编码均受损。用带阻滤波噪声进行掩蔽表明，内斜视猫任一只眼睛的检测通道调谐宽度是对照猫的两倍。在随后的实验中，发现两名人类内斜视患者的空间调谐特征正常，这表明人类内斜视与猫因眼肌切断诱发的内斜视之间存在根本差异。
