A HAWK’S VISION


HAWK SOARING & SITING, Jamestown, NC

I recently noticed this red shoulder hawk perched on a nearby branch by my driveway.  The hawk sat motionless as I drew closer with my trusty iPhone at the ready to quickly capture an image before he bolted.  In all my years outside in nature, that’s the closest I’ve ever come to a vigilant hawk.

The eastern North Carolina Cherokee believe that when creatures cross your path, they’re bringing a message to share.  Circling hawks soaring on rising thermals are known for their keen eyesight and they are considered to be messengers of vision and clarity.  Folks are cautioned to consider that whatever you’re thinking about at the time may resolve itself and manifest in your life.  You will have the clear vision and wisdom to act accordingly.  It’s a reminder that we are not alone and spiritual guidance is always available to us.

Mankind has observed the traits of hawks for millennia and those have been incorporated into religions such as in Buddhism; the hawks represent union with the great spirit.  In Hinduism, hawks are associated with rejuvenation and hawks represent wisdom in Christianity.  The hawk was the symbol of the ancient Egyptian god Horus.

The sky is the hawk’s realm and a circling hawk grabs our attention to consider a message on its wings or in the wings for action when the time is right.  I’ve recently pondered the message that I now have more years behind me than in front of me.  That’s prompted me to savor each of those future moments even more acutely now that I have the time away from demands that consumed my working hours.  Time in retirement can be consumed just as quickly, but I’ve learned to see that and commit more time to being thankful and purposeful with the days left and act accordingly.

SUBLIMINAL EYEWITNESS ACCOUNTS

Justitia, Heemskerk

I wrote a blog two years ago titled The Catch recalling a memory of over sixty years that occurred when I was a boy playing in my first All Star baseball game.  And this memory has popped up in my mind’s eye off and on all of my life. It wasn’t an experience that the hundred or so other people who witnessed it were even aware of at the time. I alone knew that it was special.  I don’t recall the exact time or place or much else about the game, including whether we won or lost!  I just mainly remember the catch.  Leonard Mlodinow has written a book titled Subliminal about how our unconscious mind rules our behavior.  He covers some extraordinary new research on how our behavior and memory function.  Mlodinow notes that the unconscious tier of our mind is more fundamental than our conscious mind and it is the standard infrastructure in all vertebrate brains that ensures our survival and ability to pass along critical DNA genes.
 
The human sensory system sends the brain about eleven million bits of information each second.  The actual amount of information we can handle has been estimated to be fifty bits per second at most.  Scientists estimate that we are conscious of only about 5 percent of our cognitive function.  The majority goes beyond our awareness and makes our lives possible.  Even if our conscious mind is idle, our unconscious mind is always active!  That’s why it’s always a good idea to "sleep" on a vexing problem and awake with a solution.  One of the most important functions of our unconscious is processing data delivered by our eyes and about a third of our brain is devoted to processing vision.  We receive images in two dimensions and our unconscious creates three dimensions.  Many of us know that these images arrive upside down and our brain presents them to us right side up.  But did you know that there’s a blind spot right in the center of every image due to the connection between our retina and our brain?  However, the brain fills in the dead region based on the surrounding area.

There is a correlation between how the unconscious fills in the blanks for both our vision and our memories!  But that begs the question of how much of the result is accurate?  This question has far reaching implications for memory and eyewitness testimony.  Mlodinow relates that “The organization Innocence Project analyzed hundreds of people exonerated on the basis of postconviction DNA testing and found 75 percent had been imprisoned because of inaccurate eyewitness identification.  About seventy-five thousand police lineups take place each year and statistics on those show that 20 to 25 percent of the time witnesses make a choice that the police know is incorrect because these are ‘known innocents’ used to fill out the lineup.”

Our human memory system is far from perfect, but it’s good enough to retain the deep structure or gist of a situation and doesn’t let the surface structure which we only retain for seconds get in the way.  Later our unconscious fills in the estimated details based on our experience.  And if we bring a certain memory up repeatedly over time, we begin to remember the memory, not the original event.  I’ve read that we actually never recall the original event but our last memory of the event which may by now be somewhat corrupted, as in eyewitness accounts.

Mlodinow questions “Are we often wrong but never in doubt?  We might all benefit from being less certain, even when a memory seems clear and vivid.”
