Faced with Death, Our Minds Search for Happier
Thoughts
Brain allows us to think about dying without being
paralyzed by fear
Oct. 22, 2007 How does the human mind process the
inevitability of death? Philosophers and scientists have long been
interested in how the mind handles this devastating situation - both
cognitively and emotionally. One would expect, for example, that
reminders of our mortality - say the sudden death of a loved one - would
throw us into a state of disabling fear of the unknown. But that doesn't
happen.
If the prospect of death is so incomprehensible,
why are we not trembling in a constant state of terror over this fact?
Psychologists have some ideas about how we cope
with existential dread. One emerging idea--"terror management theory"
--holds that the brain is hard-wired to keep us from being paralyzed by
fear.
According to this theory the brain allows us to
think about dying, even to change the way we live our lives, but not
cower in the corner, paralyzed by fear. The automatic, unconscious part
of our brain in effect protects the conscious mind.
But how does this work?
Psychologists Nathan DeWall of the University of
Kentucky and Roy Baumeister of Florida State University ran three
experiments to study existential dread in the laboratory.
They prompted volunteers to think about what
happens physically as they die and to imagine what it is like to be
dead. It's the experimental equivalent of losing a loved one and
ruminating about dying as a result.
Once the volunteers were preoccupied with thoughts
of death and dying, they completed a series of word tests, which have
been designed to tap into unconscious emotions.
For example, volunteers might be asked to complete
the word stem "jo_" to make a word. They could make a neutral word like
job or jog, or they might instead opt for the emotional word joy.
Or, in a similar test, they might see the word
puppy flashed on a screen, and they would instantaneously have to choose
either beetle or parade as the best match. Beetle is closer to puppy in
meaning, but parade is closer to puppy in emotional content. The idea is
that the results represent the unconscious mind at work.
The results, as reported in the November issue of
Psychological Science, a journal of the Association for Psychological
Science, are intriguing.
The volunteers who were preoccupied with thoughts
of death were not at all morose if you tapped into their emotional
brains. Indeed, the opposite: they were much more likely than control
subjects to summon up positive emotional associations rather than
neutral or negative ones.
What this suggests, the psychologists say, is that
the brain is involuntarily searching out and activating pleasant,
positive information from the memory banks in order to help the brain
cope with an incomprehensible threat.
