Longitudinal Twin Study

Had no idea there was such a thing as Twin Studies (click on title above for one of the studies I'm interested in).

Looking into the findings within this research could help me in understanding how this type of sibling behavior characteristically differs from that of non-twin siblings - especially sisters.



In my doc class last night we talked briefly about MKA and whether or not those of us with sisters would ever pose this way together. The answer was unanimously "no."

So right now I'm interested in finding answers to the following questions: Does being a twin change how one interacts with his/her sibling? Is their bond different? And if so, how exactly? Also, do twins feel less like two separate people than non-twin siblings? And finally, since MKA are fraternal twins, how does this factor in?

I definately need to find out more about the ways in which fraternal twin behaviors compare to those of identical twins.
