Interesting comments from all to your question, Patrik.
This topic has been taken up in the mediational theories of mind class as
Helena's way of responding ("I take the idea of the "prime" or "correct"
unit of analysis to mean the
smallest bundle of things that you'd want to be sure you were keeping in
mind when thinking about something.") is pretty nearly exactly what Ed
Hutchins says when asked
this question, but he deals with some of the sub-parts differently. And that
is how I view Yrjo and
Yrjo is asked, " But what about individual subjectivity, what do you have to
say about that"?
Jim is asked " What do you mean by context"
Yrjo says "the activity is the context"
Jim says "history is carried in the mediational means"
Yrjo asks if "situation" in Burke's pentad is a sufficient inclusion of
Jim worries that using the terms cultural-historical instead of
socio-cultural commits one to a Marxist progressivist interpretation of
Mike worries that leaving out history denudes culture of its historical
LSV says that the unit of analysis for understanding the relationship
between language and thought/speech and thinking/ is word meaning.
Many worry that something closer to discourse is the appropriate unit of
analysis for THAT topic.
Many question if Vygotsky was an activity theorist at all, or just a
semiotic idealist, or too micro in his analysis, or.......
Mike ends this note by saying that he would like to meet an expert with the
right answer and joins bb and masked lp in disclaiming any
appropriate training. I am just a student of WK Estes and AR Luria who is
seeking to understand the nature of human experience(s)
and who sure does like that nice exposition of the interleaving of material
and ideal in human experience from Dewey that Matt Brown
Got some rain here in So Cal. Whew. We need it!
