颞枕分布的 N170 ERP 组件被假设反映熟练读者的印刷调整。这项研究调查了熟练的聋人和听力读者（匹配阅读能力，但不匹配语音意识）是否表现出相似的 N170 模式，因为他们学习阅读的经历不同。 32 名聋哑人和 32 名听力正常的成年人在一项熟悉度判断任务中观察了单词和符号串。在 N170 时期（120-240 毫秒），听力正常的读者在左半球 (LH) 颞顶叶和枕叶部位对单词产生的消极性比符号更大，而聋哑读者仅在枕叶部位表现出这种不对称性。线性混合效应回归用于检查阅读、拼写和语音技能的连续测量对 N170（120-240 毫秒）的影响。对于聋哑读者来说，更好的阅读能力与右半球 (RH) 上较大的 N170 相关，但对于听力正常的读者来说，更好的阅读能力与较小的 RH N170 相关。对于聋哑读者来说，更好的拼写能力与较大的枕骨 N170 相关，但对于听力正常的读者来说，这种关系很弱。对于听力正常的读者来说，更好的语音意识与左侧较小的 N170 相关，但对于聋哑读者来说，这种关联在右侧较弱。结果支持听力正常读者左偏颞顶叶 N170 的语音映射假说，并表明熟练阅读的特点是聋人和听力正常的成年人的打印神经调谐模式不同。
The temporo-occipitally distributed N170 ERP component is hypothesized to reflect print-tuning in skilled readers. This study investigated whether skilled deaf and hearing readers (matched on reading ability, but not phonological awareness) exhibit similar N170 patterns, given their distinct experiences learning to read. Thirty-two deaf and 32 hearing adults viewed words and symbol strings in a familiarity judgment task. In the N170 epoch (120–240 ms) hearing readers produced greater negativity for words than symbols at left hemisphere (LH) temporo-parietal and occipital sites, while deaf readers only showed this asymmetry at occipital sites. Linear mixed effects regression was used to examine the influence of continuous measures of reading, spelling and phonological skills on the N170 (120–240ms). For deaf readers, better reading ability was associated with a larger N170 over the right hemisphere (RH), but for hearing readers better reading ability was associated with a smaller RH N170. Better spelling ability was related to larger occipital N170s in deaf readers, but this relationship was weak in hearing readers. Better phonological awareness was associated with smaller N170s in the LH for hearing readers, but this association was weaker and in the RH for deaf readers. The results support the phonological mapping hypothesis for a left-lateralized temporo-parietal N170 in hearing readers and indicate that skilled reading is characterized by distinct patterns of neural tuning to print in deaf and hearing adults.
