最近的研究表明，刺激识别的视觉跨度可以通过知觉学习来扩大。由于英语和音乐阅读都涉及从左到右的顺序符号处理，因此音乐阅读体验可以通过感知学习来增强符号识别，尤其是在右视野 (RVF) 中。相比之下，由于中文可以从各个方向阅读，而且汉字的组成部分不会始终形成左右结构，因此这种假设的 RVF 增强效果可能在汉字识别中受到限制。为了验证这些假设，我们在这里招募了以中文为第一语言 (L1) 和以英语为第二语言 (L2) 的音乐家和非音乐家，以识别音符、英文字母、汉字、和新颖的符号（藏文字母）呈现在屏幕上不同的偏心和视野位置，同时保持中心注视。我们发现，在英语字母识别中，在中心 RVF 位置取得超越机会表现的音乐家明显多于非音乐家。在汉字或新符号识别中没有观察到这种效果。我们还发现，在音符识别中，音乐家在中心 RVF 条件下的准确性优于非音乐家，这与在英语字母识别中观察到的视觉跨度中的 RVF 增强效果一致。这些结果表明，音乐阅读体验对刺激识别视觉跨度的调制取决于所涉及的感知过程的相似性。

Music-reading expertise modulates the visual span for English letters but not Chinese characters

Recent research has suggested that the visual span in stimulus identification can be enlarged through perceptual learning. Since both English and music reading involve left-to-right sequential symbol processing, music-reading experience may enhance symbol identification through perceptual learning particularly in the right visual field (RVF). In contrast, as Chinese can be read in all directions, and components of Chinese characters do not consistently form a left-right structure, this hypothesized RVF enhancement effect may be limited in Chinese character identification. To test these hypotheses, here we recruited musicians and nonmusicians who read Chinese as their first language (L1) and English as their second language (L2) to identify music notes, English letters, Chinese characters, and novel symbols (Tibetan letters) presented at different eccentricities and visual field locations on the screen while maintaining central fixation. We found that in English letter identification, significantly more musicians achieved above-chance performance in the center-RVF locations than nonmusicians. This effect was not observed in Chinese character or novel symbol identification. We also found that in music note identification, musicians outperformed nonmusicians in accuracy in the center-RVF condition, consistent with the RVF enhancement effect in the visual span observed in English-letter identification. These results suggest that the modulation of music-reading experience on the visual span for stimulus identification depends on the similarities in the perceptual processes involved.
