Inattentional blindness experiments

Inattentional blindness experiments provide evidence that without attention we may fail to perceive things that are clearly visible in the field of view.Inattentional deafness can occur when attention to a high-load visual search task impairs the ability to detect sounds.Change blindness is the inability to detect changes in a scene. It is another example of how inattention can affect perception.Although inattentional blindness and deafness and change blindness indicate that we don’t notice everything that is happening, our perceptual system is well adapted for survival. We can be warned about possible danger by movement, and the perceptual system makes optimal use of limited processing resources by focusing on what is being attended.
