The study's purpose is to describe the cognitive profile of a sample of functionally illiterate individuals in reading, phonological awareness (PA) and rapid automatized naming (RAN), as well as to correlate the performance of these tasks. Moreover, it sought to understand how the performances in PA and RAN predict results in reading of words and pseudowords.
23 functionally illiterate adults were assessed for intelligence, reading, PA and RAN tasks.
Participants showed difficulties in PA, performing poorly in tasks involving phoneme analysis and manipulation. In RAN, they found it easier to name alphanumeric items. Regarding reading, they presented difficulties in phonological processing, with errors caused by phonological exchange. Correlation analyses indicated that reading presented higher correlations with RAN than PA. Finally, a regression analysis indicated that performance in RAN can account for more than half of participants' reading results.
In general, the profile of functionally illiterate adults presents impairment in the abilities assessed that are more evident in PA at phoneme levels as well as in naming of non-alphanumerical items. Moreover, the results in RAN explain those in word and pseudowords reading better than the results in PA.
本研究旨在描述一组功能性文盲个体在阅读、语音意识（PA）和快速自动命名（RAN）方面的认知特征，并对这些任务进行相关性分析。此外，还试图了解 PA 和 RAN 的表现如何预测单词和伪单词阅读的结果。
对 23 名功能性文盲成年人进行了智力、阅读、PA 和 RAN 任务的评估。
参与者在 PA 方面表现出困难，在涉及音素分析和操作的任务中表现不佳。在 RAN 中，他们更容易命名字母数字项目。在阅读方面，他们在语音处理方面存在困难，导致语音交换错误。相关分析表明，阅读与 RAN 的相关性高于 PA。最后，回归分析表明，RAN 的表现可以解释参与者阅读成绩的一半以上。
总体而言，功能性文盲成年人的特征表现出在 PA 层面上的音素水平以及非字母数字项目的命名等方面的能力受损，而 RAN 的结果比 PA 更能解释单词和伪单词阅读的结果。
