Skilled reading is thought to rely on well-specified lexical representations that compete during visual word recognition. The establishment of these lexical representations is assumed to be driven by phonology. To test the role of phonology, we examined the prime lexicality effect (PLE), the index of lexical competition in signing deaf (N = 28) and hearing (N = 28) adult readers of Hungarian matched in age and education. We found no PLE for deaf readers even when reading skills were controlled for. Surprisingly, the hearing controls also showed reduced PLE; however, the effect was modulated by reading skill. More skilled hearing readers showed PLE, while more skilled deaf readers did not. These results suggest that phonology contributes to lexical competition; however, high-quality lexical representations are not necessarily built through phonology in deaf readers.
熟练阅读被认为依赖于在视觉单词识别过程中相互竞争的明确的词汇表征。这些词汇表征的建立被认为是由语音驱动的。为了测试语音的作用，我们研究了启动词词汇性效应（PLE），这是词汇竞争的指标，研究对象为年龄和教育程度相匹配的匈牙利成年手语聋人读者（N = 28）和听力正常读者（N = 28）。我们发现，即使在控制阅读技能的情况下，聋人读者也没有出现启动词词汇性效应。令人惊讶的是，听力正常的对照组也表现出启动词词汇性效应减弱；然而，这种效应受到阅读技能的调节。阅读技能较高的听力正常读者表现出启动词词汇性效应，而阅读技能较高的聋人读者则没有。这些结果表明，语音有助于词汇竞争；然而，高质量的词汇表征不一定是通过聋人读者的语音构建的。
