What is “natural” about “natural contexts”? Cultural construction of human development (and its study)

The issue of using natural contexts to study human development is crucial for theoretical innovation within developmental psychology. It is argued that the opposing natural versus laboratory contexts is a culturally constructed artifact. All laboratory (or any other specially set-up contexts) are versions of the naturalistic contexts, within which developmentalists can access the redundant processes of development that are constrained by conditions in the per son-environment transaction.
