elife:人们为什么会握手--闻闻气味?

2015-03-05 徐媛媛 MedSci原创

为什么人们会握手?来自魏兹曼研究所一项新的研究表明的形成这种古老的习俗的原因之一可能是因为要闻闻对方的气味。即使我们没有意识到这一点,但握手可能会通过气味提供一种可接受的社交沟通方式。 “我们发现,人们不仅是被动地接受化学信号,也会积极的寻找他们。”一位研究员说。“啮齿动物,狗和其他哺乳动物都会闻闻自己的气味,在社交中也会互相嗅嗅,人类在进化过程中这种行为也已经保留,只有在潜意识层面上。”

为什么人们会握手?来自魏兹曼研究所一项新的研究表明的形成这种古老的习俗的原因之一可能是因为要闻闻对方的气味。即使我们没有意识到这一点,但握手可能会通过气味提供一种可接受的社交沟通方式。

“我们发现,人们不仅是被动地接受化学信号,也会积极的寻找他们。”一位研究员说。“啮齿动物,狗和其他哺乳动物都会闻闻自己的气味,在社交中也会互相嗅嗅,人类在进化过程中这种行为也已经保留,只有在潜意识层面上。”

研究员首先检测了在握手时是否确实存在气味的转移。实验人员戴手套与受试者握手,发现手套上有残留并且研究员认为人们在握手时会有若干气味进行转移。“众所周知,在握手是细菌可以通过皮肤传播,但是我们发现潜在的化学信号,可以以相同的方式传播。”弗鲁明说。

接下来,科学家们进行了一系列科学检测,想要确认这种闻手的行为的确是为了检查气味,而不仅仅是一种对陌生环境的应激行为。首先,他们测量在测试期间鼻腔气流,发现受试者真的在嗅他们自己的手,而不仅仅是将双手抬高到他们的鼻子。接下来,科学家们将不同的气味引入实验环境中,不同的气味会影响志愿者们的闻手行为。例如,当实验者手上喷上香水,志愿者们的闻手行为就会增加。相比之下,当实验者来手上带有性激素气味时,闻手行为就会降低。这些最后的测试证实了人类闻手行为的天性。

握手时不同的力度、不同持续时间长短和不同握手姿势都会传达不同的社交信息,”索贝尔教授说。“但这项研究阐述了在人类进化中,握手可能也是传递气味信号的一种方式,这种信号仍然在古老礼仪当中占有重要意义,并且依赖于潜意识”。
