Inattentional blindness is the failure to notice a fully-visible, but unexpected object because attention was engaged on another task, event, or object. (scholarpedia.org)
In most cases, studies of inattentional blindness involve a single critical trial in which an object appears unexpectedly while observers are performing their task. (scholarpedia.org)
The term "inattentional blindness" was coined by Arien Mack and Irvin Rock to describe the results of their extensive studies of the visual perception of unexpected objects. (scholarpedia.org)
Many of their studies from the early 1990s culminated in their 1998 Book entitled "Inattentional Blindness" (Mack & Rock, 1998). (scholarpedia.org)
Although Mack and Rock coined the term inattentional blindness , earlier work had explored similar failures of awareness under conditions of selective attention. (scholarpedia.org)
Recent replications and extensions of this approach by Simons and Chabris (1999) showed that such sustained inattentional blindness occurs even when the unexpected object is fully visible and the displays are not superimposed. (scholarpedia.org)

Change blindness is a perceptual phenomenon that occurs when a change in a visual stimulus is introduced and the observer does not notice it. (wikipedia.org)

Outside of the domain of psychology, phenomena related to change blindness have been discussed since the 19th century. (wikipedia.org)
Research on change blindness developed from investigation in other phenomena such as eye movements and working memory. (wikipedia.org)
The laboratory study of change blindness began in the 1970s within the context of eye movement research. (wikipedia.org)
This development in change blindness research was able to show the effects of change blindness in more realistic settings. (wikipedia.org)
This was a critical contribution to change blindness research because it demonstrated that a change can remain unnoticed with the smallest disruptions. (wikipedia.org)
Research on change blindness proceeded one step further into practical applications of this phenomenon. (wikipedia.org)
The findings are discussed in relation to theories of change blindness, new object capture, and the ecological properties of time-based visual selection. (warwick.ac.uk)
