Someone give me funding to yawn at sociopaths

Okay, so mirror neurons (neurons that fire the same way when you engage in a behavior and when you observe others engaging in the same behavior) might be involved in empathy. There's not a ton of research supporting that yet, but I think it makes a lot of sense.

I also think it makes sense for mirror neurons to be integral to the phenomenon of contagious yawning. (Apologies in advance as everyone reading this starts feeling that urge.) Kids develop theory of mind around age 4, and start yawning in response to videos of yawning around age 5. Tons of potential third variables there, I know. Just a thought.

Now I really want to go find some sociopaths and yawn at them to see if they yawn too. Or autistic people, I suppose, but there are even more potential third variables in that population.
