Texture segmentation was studied developmentally in kittens using a two-alternative forced choice jumping stand paradigm. None of 15 kittens tested solved a texture segmentation task based on orientation contrast prior to 83 days of age, despite their rapid acquisition age, despite their rapid acquisition of an analogous luminance-based image segmentation problem. However, three kittens showed rapid acquisition of the texture segmentation task when the textures were composed of non-oriented elements (dots and annuli), reaching criterion performance by 52-59 days of age. A control experiment demonstrated that kittens can discriminate between vertical and horizontal gratings comparable in line width to the oriented texture elements as early as 53 days of age. The surprisingly late appearance of orientation-based texture segmentation is considered in the context of current models of texture segmentation and is compared to recent reports of a similar finding in human infants [3,54].
利用双选强制选择跳跃台范式，对幼猫的纹理分割进行了发育研究。在15只接受测试的幼猫中，没有一只在83日龄之前能够解决基于方向对比度的纹理分割任务，尽管它们能够快速掌握类似的基于亮度的图像分割问题。然而，当纹理由无方向元素（点和圆环）组成时，三只幼猫能够快速掌握纹理分割任务，在52 - 59日龄时达到标准性能。一项对照实验表明，幼猫早在53日龄时就能区分线宽与有方向纹理元素相当的垂直和水平光栅。基于方向的纹理分割出现得惊人地晚，本文将结合当前的纹理分割模型进行讨论，并与近期关于人类婴儿类似发现的报道进行比较[3,54]。
