RE: [xmca] Marked joint activity affects neurons and synapses



Larry, 
Thank you for that last response. There is so much in your post that I wish
to respond to and most importantly the use of "reflection" as a metaphor in
your attempt to place personal development within sociocultural contexts. I
share in the struggling over this particular topic. So bear with me as I
attempt to voice the difficulty with using "reflection" as a metaphor for
biological, mental, social processes. It is not so much "reflection" in
itself but the distinction at first implied by the metaphor as a way to
characterize dynamic/active/interactive processes. In the past I have been a
fan of reflection as a metaphor so it is with the awkward discomfort of
retracting prior arguments I work through this apparently and newly emergent
critique.
First, on the distinction between tacit understandings and implicit
understandings. If something is understood tacitly first, you use the
descriptors "primary" and "secondary", which imply to me an order. It is a
linear sequence, first one and then the next. This could be considered as a
serial sequence. Can one, which emerges developmentally out of the other,
ever really exist as separate from that which was the occasion for its
origination in the first place? It is the same difficulty with serial models
of lexical access. Is it a step by step process? It does not seem likely
with more research available, and the old models have evolved to fit with
our new data and our new hypotheses.
Besides being visually attractive, reflections as images made of light,
capture some of the nature of the reflexive relationship between the whole
person, the construct of the self, and the person as seen by others:
resemblance, representation and possibly bi-directionality of influence.
However, these qualities do not, in my humble opinion, adequately encompass
all the implications of dynamic, living relationships at any level, micro,
macro, etc. and it's these implications within the larger theories that
cause my difficulties in teasing the parts from the whole, which you
describe as "inextricably co-constitutive". "Reflection" as a metaphor
implies three separate images that correspond with three separate
constructions: the person as a whole, the construction of the image of self
as separate from the whole the person (like a reflection in a mirror), and
the person as he/she appears to others (like in a painting or photograph or
even a video). One of my favorite Spanish paintings for thinking upon this
topic is Velsaquez's "Las Meninas" (1656), which depicts the image of a
scene which is a reflection in a large mirror of the painter (Velasquez
himself) painting the very same painting of the scene he is working in. All
three of the constructions can be discussed in the content of this scene:
Velasquez the physical man, the reflection of him as a self-construction,
and the man-the painter-as seen and included by the society around him (the
King and his daughter, the court,etc). However there is just one actual
image of the man before us when we stand and look at the painting. While
Velsaquez does a considerable job creating a sense of the dynamic
relationship, even involving the viewer of this painting (at a distance of
over 300 years later) through the direction of eye gaze, to consider the
dynamics between self, subject and object, do we do the same justice to our
concepts if we continue to use the metaphor of "reflection" which might
continue to impede understandings of the person, the self, and the
sociocultural context as inextricable linked? The nature of the relationship
of a living thing within a system of other living things is both dialogical
and ecological. I concur with your last statement: 
The self-in-context points to the reality that self and context are
INEXTRICABLY CO-CONSTITUTIVE.  Therefore, from my limited perspective, self
is as much backGROUND for the sociocultural as  the sociocultural is
backGROUND for the self.
The self as constructed is experienced is a whole within the context.
If you are interested in more supporting arguments at the neurobiological
and evolutionary levels, Antonio Damasio's new book, Self Comes to Mind
(2010) which was just released this week is headed in this direction.

Hi Monica and Rod

Rod, your point that "attunement" is actually the adult orienting to the
infants need for engagement supports the point I was making that the adult
MARKS [draws attention to] the infants activity and draws the infants random
buzzing incoherent movements into a coordinated meaningful interactivity.

Monica, the concept "reflective" seems to be a central idea in my struggling
attempt to understand personal development as emerging within sociocultural
contexts. [contexts as interweaving]  The distinction I'm reflecting is
between primary TACIT understanding and secondary EXPLICIT understanding
[and reflection] as a process that emerges from more PRIMARY ENACTMENTS that
are PRECONCEPTUAL and are TACITLY COORDINATED with others within a shared
sociocultural life world.

I'm making an assumption that human infants enter the world capable of
limited NONREFLECTIVE movements and sensory awareness and a PREREFLECTIVE
ability to "remember" something of what is sensed and tacitly coordinated.
I'm assuming that MARKED interactivity is registered and "remembered" and
guides future interactivity.

Now whenever the young infant APPEARS [as interpreted by the adult] to be
attempting some action such as grasping the adults SUPPLEMENT the infants
actions through MARKED interactions that coordinate the infants PRIMARY and
NONREFLECTIVE actions and direct the infants actions into SHARED
sociocultural activity.

This secondary MARKED coordination of activity [leading activity
coordinates the infants  tacit primary, nonconceptual enactments.  In this
process of marked coordinated activity the infant slowly, through repeated
interactivity, develops the socioculturally structured patterns of
"mind"  shared with other members of her culture.

As the infant appropriates and internalizes these coordinated sociocultural
formations for thinking and understanding [interpreting] these
sociocultural forms or "tools" provide for increasingly reflective forms of
thought [like memory and imagination] that shifts consciousness from tacit
to explicit forms of reflection.
 With the emergence of reflective capacity, verbal thought takes the form of
a conversation and becomes dialogical and the person learns to talk and
relate to themselves in similar ways that OTHERS have talked and related to
them.   This EMERGING REFLECTIVITY makes possible the capacity to be aware
of oneself as BOTH subject and object simultaneously.  This is a Meadian
perspective where a sense of ones "self" emerges as an interpretive
REFLEXIVE form of understanding that recognizes self as a particular person
with individual existence WITHIN A LIFE WORLD.

This reflective "self"-understanding has the capacity to make explicit what
was tacit in sociocultural coordination.  With self reflection comes the
"limited" capacity to influence coordinated activity.

Jack Martin states "Even as psychological persons continue to be formed by
the relational and discursive practices in which they are embedded [TACIT
understanding] they also come to contribute to those practices in innovative
ways [both TACIT and EXPLICIT] that REFLECT a self-interpreting agency.

Monica, the terms "determined" "constituted" "influenced" are various ways
to reflect on the centrality of "joint coordinated activity" in forming our
sense of our "selves" Each term emphasizes a different dialectical tension
between how "free" or "constrained" we are in our sociocultural life
worlds.  How we answer this basic question is also an historically
constituted narrative construction with "modernity" and the enlightenment
supplying a particular interpretation of our sense of an "agentic self".  My
understanding of how postmodernism answers this basic question is a notion
of "self" as an interpretive process that is socially constructed "all the
way down"  There is no "self" that is capable of "self" determination and
narratives of self determination are just sociocultural "narratives"

My own hunch [at this moment in time] is that MARKED coordinating of
interactivity [tacit and explicit] LEADS the infant into the life world.
However, the "agentic self" [limited self determination]  is a process that
is developmental. Reflective capacity is situational and a sociocultural
process that emerges within particular historical contexts. Change the
context and reflective capacity changes.

  At this particular moment in time modernity seems to privilege the notion
of the "agentic self" as standing above or outside of sociocultural contexts
and the "self" [as "ego"] is  given a dominant status in our cultural
imaginary. As we explore -reflectively- alternative cultural models  I don't
want to loose a sense of "agentic self" but I want to see the "agentic
self" as "self-in-context". Context in the spirit of "interweaving"  or as
Mike Cole & Natalia Gajdamaschko suggest "self-in-context is a WHOLE in
relation to its parts.  [from the Latin origins of the term contexere = to
weave together]  The self-in-context points to the reality that self and
context are INEXTRICABLY CO-CONSTITUTIVE.  Therefore, from my limited
perspective, self is as much backGROUND for the sociocultural as  the
sociocultural is backGROUND for the self.
