dear Illuminatidinesh,

I cannot speak for everyone. There are a number of hypothesis (models) on motor control and motor development circulating world wide. The ones named in this discussion are the ones I know of.
I know nothing about what the ideas and thoughts on this subject are from Russian, Japanese, South American and Chinese colleagues for example. It is very possible they also have a number of "models" we know nothing about.

I hope colleagues from these countries are willing to share their insights with us.

Esther
