Bronfenbrenner puts it so nicely.

I couldn't have more acutely described this integral slant inspiring my current and future research aims/interests for my primate work, whether it be human or non human...

Quoted from The Ecology of Human Development: Experiments by Nature and Design, Urie Bronfenbrenner: 1979 Harvard University Press, p.128

"One can also question whether establishing transcontextual validity is, as Weisz seems to imply, the ultimate goal in the scientific study of human development, which he defines as one of finding psychological "universals", developmental principles "that can be shown to hold good across physical and cultural setting, time, or cohort" (p.2).  A distinctive property of human beings, however, appears to be precisely their capacity to adapt - to respond differently to diverse physical and cultural settings.  Given the ecologically dependent character of behavior and development in humans, processes that are invariant across contexts are likely to be few in number and fairly close to the physiological level.  What behavioral scientists should be seeking, therefore, are not primarily these universal principles but rather the laws of invariance at the next higher level  - principles that describe how developmental processes are mediated by the general properties of settings and of more remote aspects of the ecological environment."
