Visualization and the Human Brain
(Part 1)
"Imagination is more important than knowledge, for
imagination embraces the world."
--Albert
Einstein
Over the millennia, our ancestors endeavored to teach
survival skills to each subsequent generation.
It quickly became evident that maximizing their innovative capabilities enhanced
survival, increased longevity, and advanced a culture.
Anthropologists recently
discovered that the ratio of older inhabitants to younger members of a civilization
frequently determined, if and how far that group advanced
on the path from short-term primitive living to sophisticated civilizations.
Today’s mission for the next generation remains no different than it was 50,000
years ago.
Over the
eons, the remarkable human brain evolved to store
information, not merely for the purpose of being able to recall the past and its myriad details. Instead, early hominid
brains developed in a manner that permitted them to successfully navigate a frequently
dangerous and unpredictable world. While the physical world has always been
governed by the same universal natural laws, our ancestors increasingly relied
heavily upon patterns and relationships in nature to anticipate the future and
to plan their behaviors accordingly in order to survive environments that were
subject to change at a moment’s notice. These early “scientist-explorers”
devoted the majority of each day to avoiding the numerous dangers while taking
advantage of any clear and present opportunity. Keys to survival were
(1)
distinguishing danger from opportunity
(2)
storing accurate memory records
(3)
visualizing appropriate responses.
Matters
relevant to the danger-opportunity continuum warranted visualization and
memorization. Early mankind learned to visualize
future possibilities by using their imagination, asking the right questions,
making observations, gathering data and information, classifying objects and
events, making predictions, thoughtfully conducting tests and experimenting,
operating on “best-guesses” and hunches, framing explanations based on
evidence, communicating ideas, using trial-and-error strategies, revising their
thinking as-needed, dedicating their lives to “making sense” of their
environment –the ultimate quest of human knowledge. At the core of these new
competencies was a complex web of curiosity, inferential and abstract thinking,
not for academic purposes, but for survival.
Two million
years ago, Homo habilis
began an exponential brain growth enlarging both the cerebral cortex and
expanding the cranium to encase and protect a much larger brain. Within a
million years, the Homo sapiens brain doubled in size to 1350 cm2.
The most distinguishing features evolved
(1) a brain that was extremely large
relative to body mass
(2) the cognitive abilities to create
tools and technology, to reason and plan
(3) a unique ability to adapt to a
plethora of environments and circumstances, as well as to create their own
environments, rather than just adapting to natural surroundings.
