In identifying rapid sequences of three letters, subjects were worse at identifying the first and third letters when they were the same than when they were different, indicating repetition blindness (RB). This effect occurred regardless of the angular orientations of the letters, but was more pronounced when the orientations of the repeated letters were different than when they were the same. In a second experiment, RB was also evident when the first and third letters were lowercase bs or ds, presented upright or inverted, even though they are differently named when inverted (q and p, respectively). Conversely, a third experiment showed that RB occurred when the letters had the same names but were repeated in different case. These results suggest that the early extraction of letter shape is independent of its orientation and left-right sense, and that RB can occur at the levels of both shape and name.
在识别由三个字母组成的快速序列时，当首字母和第三个字母相同时，受试者识别这两个字母的能力比它们不同时更差，这表明存在重复盲视（RB）。无论字母的角度方向如何，这种效应都会出现，但当重复字母的方向不同时，这种效应比它们相同时更为明显。在第二个实验中，当首字母和第三个字母是小写的b或d，无论正立还是倒置呈现时，RB也很明显，即使它们倒置时名称不同（分别为q和p）。相反，第三个实验表明，当字母名称相同但大小写不同时重复出现，也会发生RB。这些结果表明，字母形状的早期提取与其方向和左右方向感无关，并且RB可以在形状和名称两个层面上发生。
