why we miss things in front of us

Here’s an interesting NYT article about how we miss objects in front of us.

The challenge: find the toothbrush in this messy bathroom. I saw the black one straightaway, which apparently made me an atypical person. Most people notice the smaller one first, and actually I had trouble finding it even after reading that there is a smaller one. The reason behind most people’s reaction is due to size and expectation. People expect toothbrushes to be a certain size and will look for an object that size, so our brains process the information accordingly. This is also why we may miss something that is right in front of us in a phenomenon known as inattentive blindness. We expect things to be in certain places and ignore if they are not. Remember the invisible gorilla? Christopher Chabris was a co-author:

[w]hat we pay attention to is largely determined by our expectations of what should be present.

So why did it take me less than one second to see the large toothbrush? One of the commenters on the mefi thread mentioned hidden object games. Bingo! Glad that all the time spent playing ravenhearst ddin’t go to waste.
