在3个视觉词汇识别实验中，作者考察了被试在提取词汇时对语音信息和字形信息的依赖性差异。关键的操作是在词汇判断任务的非词语境中是否存在假同音异义词。被试收到一个没有假同音字的列表（NPsH组）或17%-30%的假同音字的非单词（PsH组）。在前两个实验中，PsH组的学生比NPsH组的学生在单词测试中更快，准确性也不差。此外，在NPsH组的性能受到不利影响的语音不一致的目标的正字法附近。在最后一个实验中，使用了双重词汇判断范式，在两种条件下，对拼写相似但语音不同的对的表现不同。
In 3 visual word recognition experiments, the authors examined Ss' differential dependence on phonological versus orthographic information in accessing the lexicon. The critical manipulation was the presence or absence of pseudohomophones in the nonword context of a lexical decision task. Ss received a list with either no pseudohomophones (NPsH group) or 17%–30% pseudohomophones among the nonwords (PsH group). In the first 2 experiments Ss in the PsH group were faster and no less accurate on word trials than Ss in the NPsH group. Furthermore, performance in the NPsH group was adversely affected by phonological inconsistency in the target's orthographic neighborhood. In the final experiment, a double lexical decision paradigm was used, and performance on orthographically similar but phonologically dissimilar pairs differed in the 2 conditions.
