The unity of analysis, then, must be the psychological activity in all its
complexity (e.g., Barker's "behavior setting" redefined in cultural terms a la
Bronfenbrenner's "microcosm")), not in isolation. The quotes are taken from
the "Collected Works" (Vol. 1-6), by R. Rieber & A. Carton (Eds., N. Minick,
Trans.) , New York: Plenum.
As I commented in another note, I appreciate and understand the application
of Vygotsky's writing about units of analysis in Collected Works you site.
But he chose word meaning, not activity/context/etc as a unit.
He did not cite either Barker or Bronfenbrenner of course.
