Congenital stationary night blindness (CSNB) is a rare non-progressive retinal disorder. (wikipedia.org)
Congenital stationary night blindness (CSNB) can be inherited in an X-linked, autosomal dominant, or autosomal recessive pattern, depending on the genes involved. (wikipedia.org)

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)
