As for 3, I too am curious: the article made it seem like they normally do a 3-1, 1-3 split on limbs but can each do 2-2 if they want. From a control theory standpoint, that make sense -- you have one person focused on arms and one focused on legs, instead of an even split. (Probably not so different from being right or left handed.)
Is this accurate?
Also interesting: the one that controls more arms is the outgoing and high-strung one, while the one that controls more legs is the quieter and relaxed one. It seems unlikely that these facts are uncorrelated, though the causal relationship is anything but clear.
Incredibly, in an article full of pictures, they never actually tell you which twin is which and only address them as a unit of 'twins' in descriptions, which seems incredibly rude and depersonalizing to Krista and Tatiana. (Or, alternatively, never mention that the twins prefer to be spoken of as a unit -- which is itself an incredibly interesting fact.)
Well, in a sample size of 1, it doesn't make a huge amount of sense to discuss correlation -- the two facts both happened, and so have 100% correlation on that sample size. (But this is a basically useless statistic for making any inferences.)
The question was if we expect, given that it happened together here, we'd see it happen together more than random distribution would predict -- that is, that we see personality differences align with a split in limb control.
Since they're both changes in the manner in which one interacts with the world, and my experience of the world changes in subtle ways when I, eg, use my left hand for certain tasks or sit in certain postures, I just find it unlikely that the alignment of limb control and personality are unrelated.
