The change blindness phenomenon, which is described as changes in the environment that are missed under natural viewing conditions because they occur simultaneously with another visual disruption, was studied from a developmental perspective. Participants included a total of 65 children in 3 age groups, 6, 8, and 10 years, and 20 adults, who were administered a version of the flicker paradigm, a technique in which blank screen is inserted between presentations (Rensink, O'Regan, & Clark, 1997). Participants responded to multiple presentations of 2 objects, positioned side by side, displayed on a computer screen. In each presentation, a distracter object remained unchanged, whereas the target object changed in 1 of 3 ways, color switch, missing part, and rotation. Stimuli consisted of inanimate objects, photographs and drawings, and were displays in either 50 milliseconds or 250 milliseconds. Results revealed that 6 years old participants displayed the highest degrees of change blindness.
