在认知科学中，确定调节字母识别的视觉特征有着悠久的历史。研究人员已经提出了许多套字母特征作为重要的字母识别，但还没有这样的集合直接来自经验数据。在这里报道的研究中，我们应用气泡技术直接揭示了在五个不同的空间尺度的区域是有效的识别字母和字母。我们提供的第一个经验证据表明，行终端是最重要的功能，字母识别。我们建议，这些小功能，在几个空间尺度上表示，帮助读者区分视觉上相似的字母。
The determination of the visual features mediating letter identification has a long-standing history in cognitive science. Researchers have proposed many sets of letter features as important for letter identification, but no such sets have yet been derived directly from empirical data. In the study reported here, we applied the Bubbles technique to reveal directly which areas at five different spatial scales are efficient for the identification of lowercase and uppercase Arial letters. We provide the first empirical evidence that line terminations are the most important features for letter identification. We propose that these small features, represented at several spatial scales, help readers to discriminate among visually similar letters.
