Recent work in
experimental psychology and neurology has added to our understanding
of the mindbrain's purpose, and of its modular structure and
function.
The modules are
conditioned by nature (hard wired biases, reflexes and instincts), by
nurture (learning and enculturation linked to myths and magic) and by
serendipity (chance acts of god (?) (thunder, lightning, droughts and
floods)). The conditioning operates at the conscious and unconscious
levels.
Living
things include single celled and many celled plants and animals. They
all have to interact with their physical, biological and cultural
environments. In many celled animals this involves a sequence of
events:
sensory stimulus
|
sense organ
|
sensory nerve
|
sensory module
|
integrative module
|
evaluative module (good, neutral,
bad)
|
light
|
eye
|
sensory nerve
|
visual area
|
light, sound, smell = lion

fight or flight REACTION

Inputs from
the sense organs make up a huge amount of new data which has to be
assimilated so as to reconfigure 'reality' (including 'self') on a
continuous basis. This happens when the hard wired data and some of
the earlier data is retrieved from short and long term memory and
churned with the new data.
This data
sorting happens in the default mode network (DMN). The DMN is less
active when the mindbrain is task oriented. The DMN is most active
when it is 'resting' ie cut off from externally sourced stimulus/
response reactions. This is presumably what I think of as the
kaleidoscopic, unconscious churn.
Outputs from
the churn include thoughts, feelings and moods (TFM). Some of these
totally commandeer the attention centre while others rarely amount
to more than vague impressions. My subjective experience is that the
assimilated mini stories are rooted in TFM from times past. But most
of them are fleeting and ephemeral although that is enough to let
them influence the pattern of reality in any given moment.
For example
when shopping in the supermarket I seek out the daily specials, the
two for the price of one, the cheap own-brand options, flesh and
cheese at less than £8/kg, and wine at less than £4/bottle. The TFM
is that those who buy the more expensive options have more money than
sense; shame on them. But my sensibilities have been shaped by Dad
going bankrupt when I was about 12. So the TFM carries reflections of
the old folks shame and embarrassment.
Another
example – authority figures. I do not trust my elders and betters -
the good and great. Dad punished me for something that my little
sister did. My English teacher did not believe that I wrote my
appreciation of Wordsworth. The Minister accused me of plagiarism
when I argued the case for evolution in Bible Class. The expectation
of omniscience is ill founded.
There are
two ways of understanding awareness. While sitting quietly being
mindful you can be aware that the monkey mind is busy and let the TFM
go. While lying on the therapist's couch you can be aware of the TFM
– especially the fleeting stuff – and talk about it.
There are
many types of meditation and of talking therapy. East v West.
Following on the work of Jon Kabat Zinn there is a merging of
approaches sometimes called Buddhism Lite. The roots lie in the
psychology of perception. Reality is mind-made using language. “He
who speaks does not know.” Enough said.
