A Boston University Chobanian & Avedisian
School of Medicine researcher has developed a new theory of consciousness,
explaining why it developed, what it is good for, which disorders affect it,
and why dieting (and resisting other urges) is so difficult.
“In a nutshell, our theory is that
consciousness developed as a memory system that is used by our unconscious
brain to help us flexibly and creatively imagine the future and plan
accordingly,” explained corresponding author Andrew Budson, MD, professor of
neurology.
“What is completely new about this
theory is that it suggests we don’t perceive the world, make decisions, or
perform actions directly. Instead, we do all these things unconsciously and
then—about half a second later—consciously remember doing them.”
Budson explained that he developed this
theory along with his co-authors, philosopher Kenneth Richman PhD, at
Massachusetts College of Pharmacy and Health Sciences and psychologist
Elizabeth Kensinger, PhD from Boston College, to explain a series of phenomena
that could not be easily understood with prior theories of consciousness.
“We knew that conscious processes were
simply too slow to be actively involved in music, sports, and other activities
where split-second reflexes are required. But if consciousness is not involved
in such processes, then a better explanation of what consciousness does was
needed,” said Budson, who also is Chief of Cognitive & Behavioral
Neurology, Associate Chief of Staff for Education, and Director of the Center
for Translational Cognitive Neuroscience at the Veterans Affairs (VA) Boston
Healthcare System.
According to the researchers, this
theory is important because it explains that all our decisions and actions are
actually made unconsciously, although we fool ourselves into believing that we
consciously made them.
So, we can say to ourselves, we’re just
going to have one spoonful of ice cream and, the next thing we know, the
container is empty—because our conscious mind is not controlling our actions.
“Even our thoughts are not generally
under our conscious control. This lack of control is why we may have difficulty
stopping a stream of thoughts running through our head as we’re trying to go to
sleep, and also why mindfulness is hard,” adds Budson.
Budson and his coauthors consider a
number of neurologic, psychiatric, and developmental disorders to be disorders
of consciousness including Alzheimer’s disease and other dementias, delirium,
migraine, schizophrenia, dissociative identity disorder, certain types of
autism and more.
Lastly, their paper provides a roadmap
as to how clinicians, educators and individuals can best improve behavior and
gain knowledge, by using clinical and teaching methods that can be effective in
shaping both the conscious mind and the unconscious brain.
With further exploration, this work may allow patients to improve problem behaviors such as overeating, help us understand the ways in which brain structures support memory, and even provide insight into philosophical issues around free will and moral responsibility.
These findings appear online in the
journal of Cognitive and Behavioral Neurology.
