Lexical access and phonological decoding were tested in 100 normal adult readers and 21 adult dyslexic individuals. Within the dyslexic sample, 11 dysphonetic dyslexic and 10 dyseidetic dyslexic participants were classified on the basis of spelling patterns. In the 1st experiment, adult dyseidetic readers showed a marked deficit on the lexical-access decision task in comparison with adult dysphonetic readers. In the 2nd experiment, the phonological-decoding decision task did not separate the subtypes. A lexical-access deficit in adult dyseidetic dyslexia cannot be explained in terms of a developmental delay. A phonological-decoding deficit in adult dyseidetic dyslexia may be explained by increased involvement of the lexical procedure in phonological assembly under an analogy strategy.
对100名正常成年阅读者和21名成年诵读困难个体进行了词汇通达和语音解码测试。在诵读困难样本中，根据拼写模式将11名语音性诵读困难参与者和10名表层性诵读困难参与者进行了分类。在第一个实验中，与成年语音性诵读困难读者相比，成年表层性诵读困难读者在词汇通达判断任务中表现出明显缺陷。在第二个实验中，语音解码判断任务并未区分出这些亚型。成年表层性诵读困难中的词汇通达缺陷不能用发育迟缓来解释。成年表层性诵读困难中的语音解码缺陷可能是由于在类比策略下词汇程序在语音组装中的参与增加所致。
