We report the oral picture naming performance of the German aphasic MW who presented with frequent meaning related word substitutions (e.g. tiger ==> lion) and word finding blockings (omissions) while his phonological capacities at the single word level were nearly preserved. Targets were controlled for their 'semantic competitiveness', that is, whether there exist closely meaning related lexical competitors or not. Semantic errors were far more numerous with the highly competitive targets than with the low competitive ones. However, omissions were more frequent with the low competitive items so that the sum of the semantic errors and of the omissions was comparable in both conditions. This inverse and compensatory relationship suggests that both error types are not mutually independent. The found pattern is at odds with serial psycholinguistic theories which locate word selection (and misselection) and word form access (and blockings) at different and serially connected stages of word production but supports theories which allow for a parallel architecture in lexical activation and selection involving the word form level.
我们报告了德国失语症患者MW的口语图片命名表现。他经常出现与意义相关的词语替换（如老虎==>狮子）和找词困难（遗漏），而他在单字水平的语音能力几乎得以保留。对目标词的“语义竞争力”进行了控制，即是否存在意义紧密相关的词汇竞争者。与低竞争度目标词相比，高竞争度目标词出现的语义错误要多得多。然而，低竞争度项目的遗漏更为频繁，因此在两种情况下，语义错误和遗漏的总和相当。这种反向和补偿关系表明，这两种错误类型并非相互独立。所发现的模式与串行心理语言学理论相悖，后者将单词选择（和错误选择）以及词形通达（和阻塞）定位在单词生成的不同且串行连接的阶段，但支持那些允许在涉及词形层面的词汇激活和选择中采用并行架构的理论。
