to be honest, i think the premise of your hypothesis is neither clear enough nor restricted enough to add value to the knowledge base. they are both just too wide-ranging. i think you need to restrict the terms of "conditions" AND "creatitivity" greatly. also, your premise needs to be a question. however, ultimately, i think the term "creative" is so vague that your research will be rendered meaningless. reduce, reduce, reduce all concepts!!! e.g. your premise might read "children from large families are more artistic". but even this is too wide-ranging. so forget i mentioned anything. what do i know?
