语义可逆的句子容易被误解，通常需要更长的时间才能被儿童和成年人理解；对于失语症或特定语言障碍等语言困难的人来说，这也是一个特别大的问题。在我们的研究中，我们使用fMRI比较了41名健康参与者对语义可逆和不可逆句子的加工，以确定语义可逆性如何影响神经元的激活。通过将几个语言和非语言条件包括在我们的范式中，我们还能够测试语义可逆句子的处理是否会给特定于句子的处理带来额外的负担，如句法处理和句法-语义整合，或者对语音工作记忆造成额外的负担。我们的结果发现，在左侧顶叶-颞叶交界处的一个区域，可逆句的激活增加，当同一组参与者执行一项涉及重复说“一，三”的发音任务时，这一区域也被激活。我们的结论是，语义可逆句的加工对语音工作记忆的发音成分提出了额外的要求。
Semantically reversible sentences are prone to misinterpretation and take longer for typically developing children and adults to comprehend; they are also particularly problematic for those with language difficulties such as aphasia or Specific Language Impairment. In our study we used fMRI to compare the processing of semantically reversible and nonreversible sentences in 41 healthy participants to identify how semantic reversibility influences neuronal activation. By including several linguistic and nonlinguistic conditions within our paradigm, we were also able to test whether the processing of semantically reversible sentences places additional load on sentence-specific processing, such as syntactic processing and syntactic-semantic integration, or on phonological working memory. Our results identified increased activation for reversible sentences in a region on the left temporal–parietal boundary, which was also activated when the same group of participants carried out an articulation task which involved saying “one, three” repeatedly. We conclude that the processing of semantically reversible sentences places additional demands on the subarticulation component of phonological working memory.
