My son introduced me to the cutaneous rabbit illusion a few weeks ago. It’s a pretty interesting phenomenon. Basically the nerves in your forearm aren’t wired for strong spatial resolution, so the brain fudges a little to figure out where along your arm a given sensation originated from. As a result, some taps at your wrist and elbow can be perceived as a series of taps running up the length of your forearm, even though nothing touched the middle area.

Science Corner: Yep, I’m a Cyborg
I have absolutely experienced phantom cellphone vibrations, only I didn’t realize that was a legitimate phenomenon. I thought for sure I was feeling something else and just thinking it was my phone because I was distracted or something, which I suppose isn’t all that far removed from the proposed explanation in the article. There’s already a strong argument to be made that our smartphones, GPS devices, and similar omnipresent gadgets qualify many of us as cyborgs, but this kind of phantom sensation pretty much seals the deal in my mind.
This is also a reminder of the gap between our perception and reality. We all operate as if what we sense and then perceive is equivalent to objective reality, and for the sake of sanity that’s probably necessary. It’s also reasonable, given how often they are functionally equivalent. But I like to be reminded of the differences now and again; it’s one reason I like stage magic, for example. I see it as encouragement to engage with reality in community. After all, you can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time.
Have you ever experienced phantom cellphone vibrations? What do you think they imply about our relationship to technology? Do you think of yourself as a cyborg? How do you calibrate your perceptions with reality?
