Peter, the Damasio is absolutely fascinating, and in an accord with what I
have been recently reading.

I am interested in attending and in organizing a symposium. Here are some
topics I would like to address.
What's the role of biology in the Cultural Psychology of Development.
Mike sent this inquiry yesterday. As a preface--I'm not attending this
conference, so am not offering the following as a program topic. But Mike's
question does coincide with something I'm currently working on, which I'd
like to put out there for the group to consider.
Caveat #2: I know next-to-nothing about brain research, so my comments
should be taken as efforts to understand something I'm just learning about.
OK. Presently I'm working on 2 things that have coincidentally crossed
paths. One is the conclusion to the book I'm completing with Joel Taxel, The
Discourse of Character Education, which we hope to send off to Erlbaum soon.
The other is a dissertation by one of my doctoral students at UGA, Leslie
Susan Cook, who will begin as an assistant professor at U. of North
Carolina-Charlotte next fall.
In our character education study we contrast two conceptions of character
education, one of which focuses on bad kids and the need to remediate them
through the inculcation of character traits--honesty, responsibility, etc.
The other focuses more on the environment of the school and tries to make it
a more democratic and inclusive place. Meanwhile, Leslie is looking at
adolescent girls diagnosed with depression, focusing on the mediational
tools through which they internalize images of themselves and in turn
construct narratives about their lives.
Kids with mental health problems are at great risk in school because they
have non-normative makeups (difference is generally not an asset socially or
academically in our schools) and because kids taunt them over their
different outlooks and behaviors. The schools don't have the resources to
learn about and work with these kids, so they end up getting put in special
education, or disciplined because they think and act in ways outside what's
expected as normative and occasionally lash out at those who tease and bully
them. Many character education programs measure success by declines in
discipline measures--and so, from this perspective, the problem is that
these kids have low character.
Leslie has come across the work of Antonio Damasio, who studies the brain.
He argues that changes in the environment actually change how brains work;
that brains encode representations differently in response to changes in the
setting. From a character ed standpoint, especially with respect to mental
health, this work strongly supports the idea that a character education
initiative ought to focus on the climate, not the bad kid--a healthier
environment can contribute to healthier kids.
I also see this intersection as fitting with Mike's interest in the
relation between cultural and biological development.
I'll paste in 2 things below. First is a review of the book of Damasio's
that Leslie and I refer to (the publication date should be 1994, I think).
The second is the part of the conclusion to our book where we address this
issue. Response to our own effort to synthesize these various ideas is
welcome. thanks, Peter
Antonio Damasio:
DESCARTES' ERROR (G.P. Putnam's Sons, 1995)
(Copyright © 1999 Piero Scaruffi | Legal restrictions - Termini d'uso )
Damasio is trying to build a neurobiology of rationality. In this book he
provides a neurophysiological analysis of memory, emotions and
consciousness.
The book has three themes. 1. Human reason depends on the interaction
among several brain systems rather than on a single brain centre. 2.
Feelings are views of the body's internal organs. Feelings are percepts and
they are as cognitive as any other percept. 3. The mind is about the body:
the neural processes that are experienced as the mind are about the
representation of the body in the brain. The mental requires the existence
of a body for more than mere support: the mind is not a phenomenon of the
brain alone. The mind derives from the entire organism as a whole. The mind
reflects two types of interaction: between the body and the brain, and
between them and the environment.
The neural basis for the self resides with the continous reactivation of
1. the individual's past experience (which provides the individual's sense
of identity) and 2. a representation of the individual's body (which
provides the individual's sense of a whole). The self is continously
reconstructed. This is a purely non-verbal process: language is not a
prerequisite for consciousness. Nonetheless, language is the source of the
"I", a second order narrative capacity. Damasio's "embodied mind" is closely
related to Edelman's "self imbued with value".
Damasio's theory of convergence zones (not presented in this book) is
tackling the issue of consciousness. When an image enters the brain via the
visual cortex, it is channelled through "convergence zones" in the brain
until it is identified. Each convergence zone handles a category of objects
(faces, animals, trees, etc): a convergence zone does not store permanent
memories of words and concepts but helps reconstructing them. Once the image
has been identified, an acoustical pattern corresponding to the image is
constructed by another area of the brain. Finally an articulatory pattern is
constructed so that the word that the image represents can be spoken. There
are about twenty known categories that the brain uses to organize knowledge:
fruits/vegetables, plants, animals, body parts, colors, numbers, letters,
nouns, verbs, proper names, faces, facial expressions, emotions, sounds.
"Convergence zones" are indexes that draw information from other areas of
the brain. The memory of something is stored in bits at the back of the
brain (near the gateways of the senses): features are recognized and
combined and an index of these features is formed and stored. When the brain
needs to bring back the memory of something, it will follow the instructions
in that index, recover all the features and link them to other associated
categories. As information is processed, moving from station to station
through the brain, each station creates new connections reaching back to the
earlier levels of processing. These connections always allows the brain to
work in reverse. Convergence zones may be common to all individuals or
different from individual to individual, based on experience.
Emotions are the brain's interpretation of reactions to changes in the
world. Emotional memories involving fear can never be erased The prefrontal
cortex, amygdala and right cerebral cortex form a system for reasoning that
gives rise to emotions and feelings. The prefrontal cortex and the amygdala
process a visual stimulus by comparing it with previous experience and
generate a response that is transmitted both to the body and to the back of
the brain.
Convergence zones are organized in a hierarchy: lower convergence zones
pass information to higher convergence zones. Lower zones select relevant
details from sensorial information and send summaries to higher zones, which
successively refine and integrate the information. In order to be conscious
of something a higher convergence zone must retrieve from the lower
convergence zones all the sensory fragments that are related to that
something. Therefore, consciousness occurs when the higher convergence zones
fire signals back to lower convergence zones.
In this book Damasio formulated the "somatic-marker hypothesis", but it
was barely sketched. It will be refined as follows in following writings.
Briefly stated, the only thing that matters is what goes on in the brain.
The brain maintains a representation of what is going on in the body. A
change in the environment may result in a change in the body. This is
immediately reflected in the brain's representation of the body state. The
brain also creates associations between body states and emotions. Finally,
the brain makes decisions by using these associations, whether in
conjunction or not with reasoning.
The brain evolved over millions of years for a purpose: it was
advantageous to have an organ that could monitor, integrate and regulate all
the other organs of the organism. The brain's original purpose was,
therefore, to manage the wealth of signals that represent the state of the
body ("soma"), signals that come mainly from the inner organs and from
muscles and skin. That function is still there, although the brain has
evolved many other functions (in particular, for reasoning). Damasio has
identified a region of the brain (in the right, "non-dominant" hemisphere)
that could be the place where the representation of the body state is
maintained. At least, Damasio's experiments show that, when the region is
severely damaged (usually after a stroke), the person loses awareness of the
left side of the body.
The brain links the body changes with the emotion that accompanies it. For
example, the image of a tiger with the emotion of fear. By using both
inputs, the brain constructs new representations that encode perceptual
information and the body state that occurred soon afterwards. Eventually,
the image of a tiger and the emotion of fear, as they keep occurring
together, get linked in one brain event. The brain stores the association
between the body state and the emotional reaction. That association is a
"somatic marker".
Somatic markers are the repertory of emotional learning that we have
acquired throughout our lives and that we use for our daily decisions. The
somatic marker records emotional reactions to situations. Former emotional
reactions to similar past situations is just what the brain uses to reduce
the number of possible choices and rapidly select one course of action.
There is an internal preference system in the brain that is inherently
biased to seek pleasure and avoid pain. When a similar situation occurs
again, an "automatic reaction" is triggered by the associated emotion: if
the emotion is positive, like pleasure, then the reaction is to favor the
situation; if the emotion is negative, like pain or fear, then the reaction
is to avoid the situation. The somatic marker works as an alarm bell, either
steering us away from choices that experience warns us against or steering
us towards choices that experience makes us long for. When the decision is
made, we do not necessarily recall the specific experiences that contributed
to form the positive or negative feeling.
In philosophical terms, a somatic marker plays the role of both belief and
desire. In biological terms, somatic markers help rank "qualitatively" a
perception.
In other words, the brain is subject to a sort of "emotional
conditioning". Once the brain has "learned" what the emotion associated to a
situation, the emotion will influence any decision related to that
situation. The brain areas that monitor body changes begin to respond
automatically whenever a similar situation arises.
It is a popular belief that emotion must be constrained because it is
irrational: too much emotion leads to "irrational" behavior. Instead,
Damasio shows that a number of brain-damage cases in which a reduction in
emotionality was the cause for "irrational" behaviour.
Somatic markers help make "rational" decisions, and help making them
quickly. Emotion, far from being a biological oddity, is actually an
integral part of cognition. Reasoning and emotions are not separate: in
fact, they cooperate.
Damasio believes that the brain structures responsible for emotion and the
ones responsible for reason partially overlap, and this fact lends physical,
neural evidence to his hypothesis that emotion and reason cooperate. Those
brain structures also communicate directly with the rest of the body, and
this suggests the importance of their operations for the organism's
survival.
Mental Health and Character Education
We have briefly expressed our concern that the issue of mental health is
virtually absent from discussions about character education. Yet many
students who come to school with a mental health problems are treated as
discipline problems of the sort measured as indexes of low character in the
proposals we have studied. We believe that it is important for any character
education initiative to recognize and account for mental health in its
conception of good character, both for those with nonnormative makeups and
those with whom they interact.
Mental health is the elephant in the character education closet. The World
Health Organization (2001) reports that about 7.5 million children in the U.
S.12% of all children under 18have mental disorders, nearly half of which
lead to serious disability. Jamison (1997) found that 20% of high school
students had seriously considered committing suicide during the year prior
to his study, with most having drawn up a suicide plan; suicide is the #3
cause of death of teenagers between 15 and 19 years of age, often following
from a depressive disorder. Yet most parents and teachers feel that mental
health issues are poorly addressed in schools (Dowling & Pound, 1994;
Rappaport & Carolla, 1999), many teachers have little understanding of how
to recognize or respond to students with mental health problems (Madison,
1996), and only recently has mental health been identified as a reason to
develop an Individual Education Plan (IEP) for students.
These widespread misunderstandings have resulted in many such students
being regarded as troublesome or lacking character in schools. Yet, as
reporter Anne Imse (1999) wrote following the Columbine school shooting
tragedy,
Even teens as dangerously troubled as Eric Harris stand a good chance of
slipping through the cracks in Jefferson County and across Colorado, failing
to get badly needed mental health care. There are serious roadblocks to
getting treatment for sick kids [including]
· State prohibitions against law enforcement agencies telling schools
about a problem kid unless there's a conviction;
· Schools worrying about being saddled with psychiatric bills if they
recommend treatment, or even being sued;
· Not enough money earmarked for counselors and counseling for the state's
youth.
So, even though Jefferson County school officials have become more
sensitive to kids' mental states . . . they remain hamstrung about arranging
treatment. "We have no place to go with them," said Clark Bencomo, a
counselor at Green Mountain High School. "All we can do is suspend or
expel." "We are oftentimes reduced to putting a kid in a place where they're
safe, but it's not the right program," added Kay Cessna, intervention
services director for Jefferson County schools. "There are not enough
places." [One parent of a child with disabilities complained], "They don't
have the time, the manpower, and they don't get it."
(http://denver.rockymountainnews.com/shooting/0516ment2.shtml)
Cook (2004) finds this problem occurring in other states as well,
reporting that students with mental health problems are often put in special
education programs or disciplined when they act out, either as a consequence
of their makeup (e.g., a child with Tourette’s syndrome’s involuntary
profanity) or in response to the taunting they face from their peers.
Yet a mental health professional would surely argue that the problem is
not a lack of character and the solution is not to punish students with
mental health problems. Rather, a broader understanding of mental health
among students and facultythe sort of attention to climate we found in the
states from the Upper Midwestwould contribute to a more sympathetic and less
punitive environment for such students in school. Indeed, Damasio (1994)
argues in his somatic-marker theory against the classic Cartesian mind/body
binary, instead positing that brain and body are integrally related not just
to one another but to the environment. A change in the environment, he
finds, may contribute to changes in how one processes new information; that
is, in response to developments in the surroundings, the brain will encode
new kinds of representations of perceptions.
Conceivably, then, changes in school climate can contribute to the
emotional well-being of students whose mental makeup falls outside the
normal range. The therapy for such students is still widely debated. While
medication and counseling have benefited many with nonnormative makeups in
their relationships with others, the medical model has been criticized
because it assumes that a normative mental state is best for all. This
criticism frequently comes up in debates about whether medications for
Attention Deficit Disorder are prescribed too often for any students who
have difficulty focusing in school. Some argue that prescribing such
medications is designed more to increase the comfort levels of those around
such students than to help those students themselves.
The jury is still out concerning the question of whether people with such
diagnoses are sick and in need of medicine. Cook (2004) argues that relying
simply on medication and counseling is inadequate; that a broader
environmental change that enables an understanding and tolerance of
difference, and gives young people tools for managing their difference, is
essential to helping young people construct positive lives for themselves
and in turn contribute to a more humane society. Taking a punitive approach
to difference, she argues, is regressive and only makes life more fragile
for those characterized as different and more emotionally and cognitively
unhealthy for those who surround them.
