Semantic Fields
Semantic Fields theory views the mind as a lattice of numerous
constellations of meaning called Semantic Constellations or SeCos. A
SeCo brings together widely different elements and processes (such as
concepts, sensations, actions, words, memories, etc.) and binds them
into a meaningful whole. Through each experience, the links and
interrelations between elements are modified, thus allowing the SeCo to
reorganize itself. The SeCo, in other words, is a network that behaves
as a dynamical system, and self-organizes. It is the act of giving
meanin--to what we perceive and intend--that builds the coherence of the
SeCos, and, ultimately, of the semantic lattice. For example, take a
painter looking at a landscape.
It would be a gross oversimplification to imagine that the landscape is
simply a set of stimuli evoking conditioned responses (concepts,
memories or actions), as in the behaviorist framework. Rather, the
landscape is itself a complex natural system having developed its own
ecological web of interactions; and the mind interacts with this complex
system through multiple parallel linkage processes that imply sensory
impressions and feelings, meaningful words and concepts, imaginary
scenes, a load of past experiences, a certain state of consciousness
coloring the evolution of the perceptive process, anticipations as to
how to render it all through a painting, and so forth.
In other words, while contemplating the landscape the psyche-mind is engaging in a rich, complex and multileveled networking
process. Through this unique, novel experience, the painter’s
"Landscape" SeCo develops new internal clusters, grows with
novel meanings and new links to related clusters, and shifts to a new
global organization.
Semantic Fields theory also posits a transversal network integration of
mental and neural processes. SeCos integrate processes from lower
neuronal processes up to higher rational ones, implicating all levels
in-between (sensory, affective, imaginary, etc.). For example, learning
how to draw will imply the co-evolution of processes from different
levels, such as form-recognition, sensori-motor
acts, labeling and categorizing, feelings, intentions, etc.
This perspective, involving a transversal, psychophysical, network,
casts the mind-body problem in a different light: human knowledge and
ideas are never purely mental, abstract, or rational; rather, they are
deeply tied to sensory, motor, affective, or hormonal processes. The
model thus concurs with a growing recognition of nonrational processes
in cognition (Reber, 1993). Varela, (1991) for example, holds that
cognition develops out of--and remains tied to--a strong coupling of
sensory and motor exploratory behaviors.
Similarly, the model fits well with Charles Tart’s (1975) description
of states of consciousness as idiosyncratic patterns of sensory and
mental processes, behaviors, mind-sets, knowledge-sets, and memory.
Finally, the transversal cognitive architecture may shed light upon the
psychological complexes described by psychoanalysis--the pathological
grouping of traumatic experiences with mind-sets, behaviors, and
physiological processes. |
