Hey, look at this post!

27 Mar

Did the title draw your attention to the words I’m writing now? Maybe, maybe not. It would be much easier if we were talking in person because then I could use all sorts of facial expressions, gestures, and subtle changes in tone to convey my meaning 🙂 (See how the smiley emoticon changes the “tone” of the words that precede it?)

Hand gestures and other types of nonverbal cues are a huge part of human communication. If I had to choose humanity’s most significant digit, I would choose our magnificent opposable thumbs. These, combined with our even more magnificent brains, have allowed us to manipulate our environment and transform the world around us. So I like to exclaim that “thumbs make us human!” or “brains make us human!” or “culture/language makes us human!” Undoubtedly, these things set us apart from other species, but recent research by scholars at the Max Planck Institute for Evolutionary Anthropology argue that pointing with the index finger also makes us human. Our opposable thumbs are only “opposable” when working in conjunction with the underrated index finger – so show this finger some respect!

Slate.com has a nice summary article about the significance of pointing among developing infants. One highlight:

“A group of psychologists there [Max Planck] have documented that infants, beginning at around 1 year of age, point and react to other people pointing in remarkably sophisticated ways. Babies point to refer to events in the past and the future. They point to refer to things that are no longer there [JF: referred to as displacement in linguistic studies]. They can figure out, when an adult points across the room toward a group of objects, what exactly the adult is gesturing toward (the toy they’ve previously played with, say). They can deduce that, by pointing, an adult is trying to communicate something specific (find that toy hidden in that bucket). And not least of all, babies point because they want to share their experience of the world—that puppy—with someone else. These may just be the talents out of which humans managed to assemble minor things like culture and language.”
