Here's what my niece is capable of at 2,the abc' sand counting to 10.Thai is her native tongue.So I am thinking this just memory working and not rationalzation at work.Does this look promising?The main goal here is to determine in which direction is she started?What are her achievements showing,bear in my mind her thoughts are Thai.Being as testing here can be deduced to ethic grouping,like asking a child what fork is when she uses chop sticks.Thats the way I was told it was.I guess that can go both ways,fork,chop sticks,etc.My child gave the answer prong for fork,that you can not do.,apparently.
I believe that you are correct in that the ABCs and 123s are a matter of memory. Your niece obviously has a good memory and is probably partial to music - I am assuming that she picked up her ABCs and 123s from nursery songs? By the way, she also has strong motor skills given her ability to use chopsticks at age 2. I am not sure what else you can deduce from these facts plus she is only 2 years old. As for cultural bias, there are tests like the Raven that would remove that issue.
