美国马里兰州大学神经学家和心理学家联合进行的一项研究显示，女性的确比男性话多，其原因是女性大脑中的“语言蛋白”比较多。此前有研究称，女性一天大概说2万个单词，比男性多出1.3万个。而这项研究是首次从语言蛋白含量角度来解释男女语言表达方面的差别。研究人员对出生四天的雌雄实验鼠的观察发现，雄性实验鼠在5分钟内发出的声音是雌性老鼠的两倍，而对其脑部检测结果显示，雄性实验鼠脑中跟语言表达相关的Foxp2蛋白含量是雌性老鼠的两倍。研究人员又对十位年龄在3到5岁的儿童脑部蛋白取样分析后发现，女孩脑中的Foxp2蛋白比男孩多出30%。马里兰州大学医学院教授麦卡锡表示，研究结果表明Foxp2蛋白是哺乳动物口头交流性别差异的神经生物因素之一。 Women do really talk more than men, a study has concluded. American researchers found females are the more talkative sex because of a special “language protein” in the brain. The study, compiled by neuroscientists and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats they were males. Their findings come after it was previously claimed that ladies speak about 20,000 words a day – more than 13,000 more than men. |
