Design movements

I was wondering if the movement of streamline design is closely connected with abstract anthropomorphism. Specially the transportations design of that era have hidden anthropomorphic elements. Also 40's and 50's american design, with Fiestaware first and then Tupperware, by using a totally different color pallete than the acceptable ones, created a new great market success,with which subarbs probably would not be a sucess today.

On the other hand, you have modernism with simplicity and basic forms which are related also with child perseption and development. For example Bauhaus toys in relation with Johannes Itten's theory of colour. Simple forms, colors, shapes and materials. Can this be actually the begin of childlike design?
