I don't know how important this is for a navigator while navigation but could be important to a navigator when driving his car. I think we have all had this experience. You are stopped at a stop sign. You look to your left and to your right, see nothing and start to go and then a car comes flashing by from your left. "Where the hell did he come from?" you say to yourself. You looked and you didn't see it. I taught myself the habit to look a second time before I move the car and it is amazing how many cars you catch on the second look.

This is the best demonstration of this effect I have seen! Very cool! Just to make sure the yellow dots were not actually blinking on and off I asked my wife to look at it and change her focus at short intervals while I did the same. Each of us called out continuously either "present" or "gone" as they appeared or disappeared. Our calls did not match up. It is amazing how vivid this effect is.

What are the practical consequences of this for the navigator?

As part of my self-assigned homework I'm looking through the archives. In March 2007 Alexandre Eremenko mentioned seeing stars in the daytime and not seeing airplanes if you didn't know where to look.

This reminded me of the following link:

Followed correctly it illustrates how you can miss objects by staring instead of moving your eyes.
This relates to flying but would apply to any time when seeing is critical. - and it's fun.
