- We have the power to choose our responses, Holocaust survivor Viktor Frankl said
- The power of our perceptions can be seen with the placebo effect during clinical trials
- The way we perceive even the most basic of our senses is dependent on interpretation
Viktor Frankl was a Jewish psychiatrist who spent three years during World War II living under unspeakable circumstances in several of the most notorious Nazi concentration camps.
While imprisoned, Frankl realized he had one single freedom left: He had the power to determine his response to the horror unfolding around him.
And so he chose to imagine.
He imagined his wife and the prospect of seeing her again. He imagined himself teaching students after the war about the lessons he had learned.
Frankl survived and went on to chronicle his experiences and the wisdom he had drawn from them.
"A human being is a deciding being," he wrote in his 1946 book, "Man's Search for Meaning," which sold more than 10 million copies. "Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom."
The idea of becoming conscious of the subjectivity of our perceptions is an admittedly abstract one -- the stuff of philosophy and science fiction.
But human perceptions, and their ramifications, are very real and potentially life-changing.
For example, research shows that people may hold an unconscious bias against creativity because it represents uncertainty unless they are able to perceive that uncertainty in a positive light.
And consider the role perception plays in helping patients improve in ailments ranging from pain and depression to Parkinson's disease through a phenomenon known as the placebo effect. Though the placebo effect remains largely shrouded in mystery, researchers attribute some aspects of the placebo response to active mechanisms in the brain that can influence bodily processes such as the immune response and release of hormones.
Studies also show that perceived risk can drive behavior change. The perception of the harmful effects of smoking, for example, can influence habit and addiction.
So how might we harness the power of perception to live more conscious lives and, perhaps, to even recast the most dire situations in which we find ourselves?
The fiction of reality
Perception begins when the human brain receives data from the body's five senses. The mind then processes and applies meaning to the sensory information.
"I want to start with a game," says neuroscientist and artist Beau Lotto at the outset of his TED talk on perception. "To win this game, all you have to do is see the reality that's in front of you as it really is."
As it turns out, seeing that reality isn't as easy as it sounds, even when it comes to basic shapes and colors. Lotto uses a series of optical illusions involving light, color and space to show that even the most fundamental of our senses -- the way we perceive light and color -- can be subject to interpretation.
The variable, says Lotto, is context.
The exact same image can have an infinite number of sources in the real world. When it comes to perception -- seeing, feeling, hearing, sensing things -- there is no such thing as objectivity.
