"Why do people not noticed the slight changes in their daily lives, but when they do notice a change, it seems like they can do nothing but complain about the change."

Third

"Throughout this paper we will examine and explore the effects of change blindness on users as they operate three fast-paced websites: Facebook, Google Mail, and MSN."

Research Notes

Current Approaches to Change Blindness - Daniel J. Simons - Harvard University, Cambridge, MA, USA
Highlights and Quotes

"Across saccades, blinks, blank screens, movie cuts, and other interruptions, observers fail to detect substantial changes to the visual details of objects and scenes." (pg. 1)

"People also show change blindness when the original and altered image are separated by a “mudsplash” (O’Regan, Rensink, & Clark, 1999), by a cut or pan in a motion picture (Hochberg, 1986; Levin & Simons, 1997; Simons, 1996), and even by a real-world disruption (Simons & Levin, 1998)." (pg.2)

"Phillips, 1974; Simons, 1996). In the flicker paradigm, an original and modified image are presented in rapid alternation with a blank screen between them. Observers respond as soon as they detect the changing object. Research using this paradigm has produced two primary findings: (1) observers rarely detect changes during the first cycle of alternation, and some changes are not detected even after nearly 1 minute of alternation (Rensink et al., 1997); and (2) changes to objects in the “centre of interest” of a scene are detected more readily than peripheral or “marginal interest” changes (Rensink et al., 1997)," (pg.3)

"Both the flicker paradigm and the forced choice detection paradigm are intentional change detection tasks in that observers know that changes will occur and actively search the display to find differences. This work demonstrates that observers are change blind evenwhen their primary task is to search for change." (pg.4)
