Hi All,
A very cool observation and discovery that's consistent with my experience, and probably others of you as well. About 15 years ago, I was jogging on a hilly trail in the East Bay. My pointer sweeping the ground around me. As he crossed the trail several feet in front of with a single bound, I instantly saw a snake, a gopher snake reveal below her leap. She paid absolutely no attention to it. For me however, I came to grinding halt with an almost neon snake against an earth background. It was like it had been silhouetted. I did a quickly processed snake identification, and deftly leaped over the snake. I so vividly remembered the event.
What surprised me more than anything was how quickly I had picked up the form of the snake, and how oblivious my dog had been. How could we be so different. Well, it turns out it may be a unique inherent aspect of our primate visual systems.
