Change Blindness



I can see a movie numerous times… and with each viewing… I’ll see a detail I missed the first time around… We’re all victims of Change Blindness… a visual phenomenon… where exploitation from many folks… including movie directors… and advertisers abound. Change Blindness is a natural brain bias… not a visual suspension. When viewing scenes or situations… we typically miss changes occurring before us that are easily seen… once brought to our attention.

 Change blindness … requires a significant change to occur … in combination… with brief interruptions… such as  lights flickering… people moving… or tumultuous explosions causing a stir… For example… change blindness may strike… when a performing clown… or monkey one man band… distracts us from realizing right before us… a stand-up comedian is being hooked off stage by the cane from another’s hand… or when we rubberneck an active wreck … and dismiss the distraction… as simply benign… not realizing until seconds later… we just bypassed our approaching …road exiting sign.

The transitory disruption of change blindness… is often confused … with “In attentional blindness” or focus failure… where gazing our eyes on one non-changing object causes “other still object” unconscious exclusion behavior… 

Change blindness differs from in attentional fixed object bias blindness… in that… for us to successfully detect change  during a distraction… our brain must be able to compare a current image in our field of view… to another we hold in memory before the changing action.     In contrast… in attentional blindness does not require any comparison to memory… just a recognition that a fixed focus places viewing other still objects in awareness jeopardy.

Change blindness … is where… significant change… occurs in our view without our mind’s eye… seeing the MOVE…   It’s a funny feeling to know… our “for sure” view of reality… for ourselves… and others… when it comes to change… may not always be… something we can ultimately PROVE…
