Eleven children with early focal lesions were compared with 70 age-matched controls to assess their performance in repeating non-words, in learning new words, and in immediate serial recall, a triad of abilities that are believed to share a dependence on serial ordering mechanisms (e.g.,; ). Results for the experimental group were also compared with other assessments previously reported for the same children by. The children with brain injury showed substantial impairment relative to controls in the experimental tasks, in contrast with relatively unimpaired performance on measures of vocabulary and non-verbal intelligence. The relationships between word learning, non-word repetition, and immediate serial recall were similar to those observed in several other populations. These results support previous reports that there are persistent processing impairments following early brain injury, despite developmental plasticity. They also suggest that word learning, non-word repetition, and immediate serial recall may be relatively demanding tasks, and that their relationship is a fundamental aspect of the cognitive system.
将11名患有早期局灶性病变的儿童与70名年龄匹配的对照组儿童进行比较，以评估他们在重复非单词、学习新单词和即时序列回忆方面的表现，这三项能力被认为都依赖于序列排序机制（例如；）。实验组的结果也与之前报道的同一批儿童的其他评估结果进行了比较。与词汇和非语言智力测试中相对未受损的表现相比，脑损伤儿童在实验任务中相对于对照组表现出明显的损伤。单词学习、非单词重复和即时序列回忆之间的关系与在其他几个人群中观察到的关系相似。这些结果支持了之前的报告，即尽管存在发育可塑性，但早期脑损伤后仍存在持续的加工障碍。它们还表明，单词学习、非单词重复和即时序列回忆可能是要求相对较高的任务，并且它们之间的关系是认知系统的一个基本方面。
