從一個謊話刺激大腦杏仁核的實驗說起

from IC之音|講理就好 · host puni.li

這是來自2016年《自然神經科學》(Nature Neuroscience)期刊,倫敦大學學院(University College London)的研究團隊發表的研究。科學家透過 功能性磁振造影(fMRI) 測量,發現人類在說謊時,會刺激活化大腦的杏仁核。但是謊話說得越多,杏仁核的活動也越小,最終使得說謊者對謊言逐漸無感麻痺。參考報導:Your brain gets used to lying as you do it more研究人員認為,這項成果似乎證明了一種「滑坡效應」,顯示大腦對說謊逐漸麻痺。這是否說明了很多歷史上的野心家、或是龐氏騙局的發起人,為何可以大放厥詞讓所有人都相信,因為他們已說謊成自然?但是實驗中提及,如果給予譴責懲罰,結果可能會不一樣。所以在教育孩子的時候,要正確地引導他們,讓孩子了解誠實才是上策。
