change blindness

Change blindness is a phenomenon where individuals fail to notice significant changes in their visual field, especially when these changes occur during a saccade, which is a rapid eye movement. This occurs because vision is impaired during saccades due to the image moving too fast and a process called saccadic suppression that temporarily blocks vision.

The brain processes visual information through various specialized areas, analyzing features like color, depth, and motion. However, how these separate processing streams are integrated into a single, coherent visual experience is not fully understood. It is believed that we retain little information from one fixation (the period between saccades when we take in visual information) to the next, which contributes to our inability to detect changes. This phenomenon highlights that our perception of a stable world is an interpretation rather than a direct reflection of continuous visual input.123
