五歲兒童在句子形態句法處理中啟動顳葉而非額葉機制

// Five-year-old children engage temporal but not frontal mechanisms during morphosyntactic processing of sentences

本研究利用功能性磁振造影（fMRI）觀察五歲兒童處理句中動詞時態語素的腦部機制｜結果顯示顳葉區域，特別是負責語音處理的後上顳回，活化明顯；與語意處理相關的額葉區域未見活化｜未發現腦部活化與語言能力間相關，顯示幼兒主要依賴語音機制進行形態句法處理，額葉語言網絡尚未成熟。

// This study used fMRI to examine how five-year-old children process finiteness-related verb morphemes in spoken sentences, focusing on phonological and semantic brain mechanisms. Results showed strong activation in temporal regions, especially the posterior superior temporal gyrus linked to phonological processing, but not in frontal areas associated with semantic processing. There was no correlation between brain activation and language skill levels. The findings suggest young children rely on temporal, phonological mechanisms for morphosyntactic processing, with the frontal language network not yet developed.
