Example of images that can be used in a change blindness task. Although similar, the two images have a number of differences. Change blindness is a perceptual phenomenon that occurs when a change in a visual stimulus is introduced and the observer does not notice it.
Simons is best known for his work on change blindness and inattentional blindness, two surprising examples of how people can be unaware of information right in front of their eyes. His research interests also include visual cognition, perception , memory , attention , and awareness .
The following criteria are required to classify an event as an inattentional blindness episode: 1) the observer must fail to notice a visual object or event, 2) the object or event must be fully visible, 3) observers must be able to readily identify the object if they are consciously perceiving it, [3] and 4) the event must be unexpected and the failure to see the object or event must be due ...
Change blindness refers to an inability to detect differences in two successive scenes separated by a very brief blank interval, or interstimulus interval (ISI). [19] As such change blindness can be defined as being a slight lapse in iconic memory. [20] When scenes are presented without an ISI, the change is easily detectable.
Motion silencing stems from the study of change blindness which in essence is the failure to detect change in the visual field. [9] The phenomenon has been studied extensively, by means of such methods as flicker tasks, [10] forced saccade tasks, [11] mudsplashes, [12] disrupted and undisrupted scene transitions, [13] incremental scene rotation, [14] and videos.

For example, according to Best Friends Network staff, cats can exist with barely noticeable behavioral changes as their loss of sight comes on gradually. As they start losing vision, felines begin ...
Saccadic masking, also known as (visual) saccadic suppression, is the phenomenon in visual perception where the brain selectively blocks visual processing during eye movements in such a way that neither the motion of the eye (and subsequent motion blur of the image) nor the gap in visual perception is noticeable to the viewer.
Frequency is affected by factors like diet, activity level, stress, lifestyle changes, medications and health conditions, Hanouneh explains. He says that the most important way to tell if you're ...
