How has the study of change-blindness phenomena contributed to our understanding of visual attention and perception?
The so-called changed-blindness phenomena has given some clues of how human vision and perception really works and it is, therefore, interesting to examine the results of the related studies and to make conclusions upon this. Precisely this will be the effort of this brief paper which will deal with the contribution changed blindness studies have made to the understanding of vision and perception (Levin et al, 2000; Shapiro, 2000; Simons, 2000). Recent psychological investigations have revealed that almost nobody is very good at remarking supposedly obvious changes to visible elements of the environment. For example, it has been discovered that most individuals miss out to detect significant changes to scenes while watching a movie. The detection failures are remarkable and include the viewer even not detecting when a conversation partner has being exchanged with another (e.g. Grimes, 1996; Blackmore et al, 1995; Pashler, 1988; Phillips, 1974; Levin & Simons, 1997; cited in Simons 2000
