Re: [xmca] Educational neuroscience - from Mike Cole

As I see Luria’s dual stimulation, Andy, you have to go
beyond the idea of sub-systems.  It’s
mosaics, I’m afraid.

Two actions closely related yes.  But, in fact, the first one has some hidden attributes
(or maybe some hiding states) and so you barge in with the second closely
related in some (maybe odd) way– seemingly abandoning the first – and the
hidden or hiding in the first can be made observable.  

So whether Luria thinks about a clinician or
a diagnostician or an actively engaged patient, the dual stimulation method can
serve one well.

Zasetsky, for instance, learned a way to recognize printed letters/words
(a picture visualization as I recall) in spite of massive brain damage but
sometimes it failed (some part was hidden from use) so he’d appear to abandon
the first stimulation and start up the second stimulation (maybe reciting the
letters in some order).  The second was so
closely yoked to the first that sooner or later there’d be a sort of collision.  Using the second stimulation, he’d sooner or
later get to the letter that had been “hiding” when he had been relying on his
first stimulation so whoosh the second stimulation would now be interrupted and
abandoned by the not really ever abandoned first simulation and he could go
back to recognizing letters and getting the words in the print using his
preferred first system.

So we have 4 distinct but interrelated concepts: system, model, unit of analysis and method.
I will try to formulate a view on unit of analysis and method.
The idea of "artefact-mediated (collaborative) action" as a unit of analysis (a generalisation of "word meaning") is the basis for the "method of dual stimulation," as I see it.
Once you have a concept of that S - X - R triangle, as the unit of action, then it suggests a method of investigation based on offering the auxilliary stimulus, the artifact X, to the subject, S, to assist them to complete the task, R. By varying teh artefact X and the task R, investigation of S is possible.

Likewise, let us suppose that you see the mind as a psychological system made up of functional subsystems each of which are interconnected, irrespective of whether the subsystem in question itself produces observable phenomena. This could be represented in a diagram, too, something like S -> Ssys1 ---> Ssys2 -> R, meaning that every subsystem (Ssys1) is connected with every other (Ssys2), and disturbance of Ssys1 will cause a disturbance to Ssys2, which may be manifeted in an observable response, R.
So the implication of this is that the "unit of analysis" of an entire psychological system is two functional subsystems with an interconnection.  Ssys1 --- Ssys2.
This is not trivial, because much of Ssys1 will not be observable, and this unit of analysis allows the investigator to study Ssys1 by means of the observable responses via Ssys2.

The unit of analysis suggests the method.
