The basic issues are: 
is development continuous or discontinous stages
does everyone grow up the same or is it based on context
is development determiend by nature vs nurture or plasticity?

Personally, i believe that all of these issues are important to be adressed when we're talking about a certain development, with only one additional issue
That issue would be: Is the development good or bad ?'
Addressing this issue will make us know whther to make an effor to stop the development or just let it be.
