在一项配套研究中，患有诵读困难的成年人和可能有儿童言语失用症病史的成年人在非单词重复、多音节真实的单词重复和非单词解码过程中表现出处理顺序信息的困难。结果表明，在非词阅读过程中，视觉编码出现了一些错误，在非词重复过程中，各个层次的处理，特别是短期记忆的存储/提取，以及复杂的真实的词重复过程中的运动规划和编程。为了进一步研究短期记忆的作用，招募了一名患有短期记忆障碍（MI）的参与者。MI被确认为在句子重复和三个非单词重复任务中表现不佳，所有这些任务都具有较高的短期记忆负荷，而在阅读、拼写和静态口头知识测试中观察到典型的表现，所有这些任务都具有较低的短期记忆负荷。实验结果表明，在多音节真实的字重复，但高计数的顺序错误，特别是迁移和同化，在非字重复，支持短期记忆的顺序处理赤字在非字重复的轨迹。结果也是一致的假设，即在复杂的真实的字重复，短期记忆被绕过的字是公认的，并从长期记忆中检索之前，生产的字。
In a companion study, adults with dyslexia and adults with a probable history of childhood apraxia of speech showed evidence of difficulty with processing sequential information during nonword repetition, multisyllabic real word repetition and nonword decoding. Results suggested that some errors arose in visual encoding during nonword reading, all levels of processing but especially short-term memory storage/retrieval during nonword repetition, and motor planning and programming during complex real word repetition. To further investigate the role of short-term memory, a participant with short-term memory impairment (MI) was recruited. MI was confirmed with poor performance during a sentence repetition and three nonword repetition tasks, all of which have a high short-term memory load, whereas typical performance was observed during tests of reading, spelling, and static verbal knowledge, all with low short-term memory loads. Experimental results show error-free performance during multisyllabic real word repetition but high counts of sequence errors, especially migrations and assimilations, during nonword repetition, supporting short-term memory as a locus of sequential processing deficit during nonword repetition. Results are also consistent with the hypothesis that during complex real word repetition, shortterm memory is bypassed as the word is recognized and retrieved from long-term memory prior to producing the word.
