有严重听力损失的人通常不能获得阅读正字法的能力，这些正字法编码了口语的声音属性。然而，一些严重失聪的人确实在年龄适当的水平上学习阅读。什么是熟练的聋人读者从不熟练的读者区分的问题是知之甚少，但专题，努力制定适当和有效的干预措施是必要的。本研究采用功能性磁共振成像（fMRI）技术检测了聋人（N = 21）的大脑活动，比较了熟练阅读者（N = 11）和不熟练阅读者（N = 10）在广泛使用的内隐阅读测试中的表现。 熟练的聋人阅读者激活左额下回和左颞中回和上级回的模式与听力正常的阅读者报告的区域一致。与此相反，不太熟练的读者表现出的反应模式，其特征是下额叶和中额叶激活（右>左），这与在语标阅读的研究中报道的区域有一些相似之处，提高了这些人使用的可能性，即与传统上在听力个体阅读基于声音的脚本中观察到的模式相比，他们使用的是一种质的不同的正字法处理模式。熟练和不熟练的读者的评价指向不同的模式处理印刷体英语单词。重要的是，这些初步发现使我们能够开始建立语言和教育因素对神经系统的影响，这些神经系统是深度耳聋个体阅读成就的基础。
Individuals with significant hearing loss often fail to attain competency in reading orthographic scripts which encode the sound properties of spoken language. Nevertheless, some profoundly deaf individuals do learn to read at age-appropriate levels. The question of what differentiates proficient deaf readers from less-proficient readers is poorly understood but topical, as efforts to develop appropriate and effective interventions are needed. This study uses functional magnetic resonance imaging (fMRI) to examine brain activation in deaf readers (N = 21), comparing proficient (N = 11) and less proficient (N = 10) readers’ performance in a widely used test of implicit reading. Proficient deaf readers activated left inferior frontal gyrus and left middle and superior temporal gyrus in a pattern that is consistent with regions reported in hearing readers. In contrast, the less-proficient readers exhibited a pattern of response characterized by inferior and middle frontal lobe activation (right>left) which bears some similarity to areas reported in studies of logographic reading, raising the possibility that these individuals are using a qualitatively different mode of orthographic processing than is traditionally observed in hearing individuals reading sound-based scripts. The evaluation of proficient and less-proficient readers points to different modes of processing printed English words. Importantly, these preliminary findings allow us to begin to establish the impact of linguistic and educational factors on the neural systems that underlie reading achievement in profoundly deaf individuals.
