Change blindness is a psychological phenomenon that occurs when a change in a visual stimulus goes unnoticed by the observer. For example, an individual fails to notice a difference between two images that are identical except for one change. The reasons these changes usually remain unnoticed by the observer include obstructions in the visual field, eye movements, a change of location, or a lack of attention. The brain regions that have been observed as active during change blindness are the prefrontal lobe, the fusiform face area, the pulvinar, the cerebellum, the inferior temporal gyrus, the parietal lobe, and the frontal lobe. A common method of testing change blindness is the flicker paradigm, in which a blank screen is presented in the middle of an image and an altered form of that image that may distract the perceiver's attention. Change blindness has become a highly researched topic due to newly discovered implications in practical applications such as eyewitness testimony and distractions while driving.

Famous quotes containing the words change and/or blindness:
“I leave the governors office next week, and with it public life ... [which] has been on the whole a pleasant one. But for ten years and over my salaries have not equalled my expenses, and there has been a feeling of responsibility, a lack of independence, and a necessary neglect of my family and personal interests and comfort, which make the prospect of a change comfortable to think of.”
—Rutherford Birchard Hayes (18221893)
“Oh blindness to the future! kindly givn,
That each may fill the circle markd by Heavn:”
—Alexander Pope (16881744)
