词汇质量假说认为，语音、正字法和语义表征的质量影响阅读理解。在研究1中，我们评估了97名聋人和98名听力正常成人的词汇质量对阅读理解的贡献。虽然语音意识对听力读者有很强的预测作用，但对于聋人读者，预测阅读理解的是拼写精确度和语义知识，而不是语音(通过两种不同的测试进行评估)。对于聋人读者，阅读系统的架构通过将依赖从(粗粒度的)语音表示转移到高质量的正字法和语义表示来适应。在研究2中，我们考察了83名聋人美国手语(ASL)变量对阅读理解的贡献。手指拼写(FS)和ASL理解技能预测阅读理解能力。我们认为，手语理解可能加强了从正字法到语义的映射，手语理解可能是聋人手语熟练阅读发展的语言学基础。
The lexical quality hypothesis proposes that the quality of phonological, orthographic, and semantic representations impacts reading comprehension. In Study 1, we evaluated the contributions of lexical quality to reading comprehension in 97 deaf and 98 hearing adults matched for reading ability. While phonological awareness was a strong predictor for hearing readers, for deaf readers, orthographic precision and semantic knowledge, not phonology, predicted reading comprehension (assessed by two different tests). For deaf readers, the architecture of the reading system adapts by shifting reliance from (coarse-grained) phonological representations to high-quality orthographic and semantic representations. In Study 2, we examined the contribution of American Sign Language (ASL) variables to reading comprehension in 83 deaf adults. Fingerspelling (FS) and ASL comprehension skills predicted reading comprehension. We suggest that FS might reinforce orthographic-to-semantic mappings and that sign language comprehension may serve as a linguistic basis for the development of skilled reading in deaf signers.
