Some children learn to read accurately despite language impairments (LI). Nine- to 10-year-olds were categorized as having LI only (n = 35), dyslexia (DX) only (n = 73), LI + DX (n = 54), or as typically developing (TD; n = 176). The LI-only group had mild to moderate deficits in reading comprehension. They were similar to the LI + DX group on most language measures, but rapid serial naming was superior to the LI + DX group and comparable to the TD. For a subset of children seen at 4 and 6 years, early phonological skills were equally poor in those later classified as LI or LI + DX. Poor language need not hinder acquisition of decoding, so long as rapid serial naming is intact; reading comprehension, however, is constrained by LI.
一些儿童尽管存在语言障碍(LI),仍能准确学会阅读。9至10岁的儿童被分为仅患有语言障碍(n = 35)、仅患有诵读困难(DX;n = 73)、语言障碍+诵读困难(n = 54)或发育正常(TD;n = 176)。仅患有语言障碍的组在阅读理解方面存在轻度至中度缺陷。他们在大多数语言指标上与语言障碍+诵读困难组相似,但快速序列命名能力优于语言障碍+诵读困难组,与发育正常组相当。对于4岁和6岁时接受观察的一部分儿童,那些后来被归类为语言障碍或语言障碍+诵读困难的儿童早期语音技能同样较差。只要快速序列命名能力完好,语言能力差不一定会阻碍解码能力的习得;然而,阅读理解会受到语言障碍的限制。
