// You again? 14-month-olds show neural signatures of lexical-semantic activation for novel instead of familiar voices
研究測試14個月大嬰兒是否更容易處理熟悉聲音中的詞意｜透過腦波N400反應比較語意一致與不一致詞對｜結果顯示僅在不熟悉聲音下出現明顯N400效應，代表嬰兒對陌生講者詞意差異更敏感｜顯示嬰兒在無視覺提示下可理解詞語關係，且對不熟悉聲音的語言任務反應更積極。
// This study tested whether familiar voices ease word meaning processing in 14-month-olds by measuring the N400 brain response to congruent and incongruent word pairs. Infants were exposed to a familiar voice before the experiment and then heard both familiar and unfamiliar voices during testing. Results showed a clear N400 effect only for unfamiliar voices, indicating infants detected meaning differences more with unfamiliar speakers. This suggests 14-month-olds process word relationships without visual cues and may engage more with unfamiliar voices in language tasks.
