My Sister Rosa: disquieting YA novel about loving an adorable psychopath

Che Taylor is 17 and his little sister, Rosa, is 10 -- and she's a psychopath. His itinerant parents are relocating the family -- again -- to start (another) social enterprise, this one in New York, and Che knows that when the plane from Bangkok touches down, Rosa will resume her secret campaigns of psychological torture and ghastly cruelty, and that he'll be the only one who can see through the cherubic, charismatic, ringleted facade to the monster underneath. If only he didn't love her so much...

Psychopaths are more immune to "contagious" yawns

When you see someone yawn and then feel the urge to yawn yourself, it's a sign of social traits like empathy. According to new research from Baylor University, people who scored higher on the Psychopathic Personality Inventory test were less likely to "catch" a yawn. From Baylor University:

Based on the psychological test results, the frequency of yawns and the amount of physiological response of muscle, nerve and skin, the study showed that the less empathy a person had, the less likely he or she was to "catch" a yawn.

"The take-home lesson is not that if you yawn and someone else doesn't, the other person is a psychopath," (lead researcher Brian) Rundle cautions. "A lot of people didn't yawn, and we know that we're not very likely to yawn in response to a stranger we don't have empathetic connections with.

"But what we found tells us there is a neurological connection -- some overlap -- between psychopathy and contagious yawning. This is a good starting point to ask more questions."

And if you'd like to learn more about what makes a psychopath, I highly recommend Jon Ronson's excellent book "The Psychopath Test: A Journey Through the Madness Industry."
