"From an evolutionary perspective, this makes sense," said study co-author Matt Thimgan, a Washington University postdoctoral researcher. "If you're starving, you want to make sure you're on the top of your game cognitively, to improve your chances of finding food rather than becoming food for someone else."
“這從進化的角度看是行得通的,”研究作者之一、華盛頓大學的馬特說道。“如果你處在饑餓狀態,你就會努力設法清醒地掌控自己的生存狀態,以增加尋獲食物的機會,而不是成為別人的食物。”
