Effect Of Scenes Presentation On Change Detection In Ficker Paradigms

Change detection is the apprehension of change in the world around us.The phenomenon that observers fail to detect substantial changes of scenes during a visual disruption is called change blindness. It is one of the focus of cognitive psychology since the mid-1990s. This phenomenon has been observed in many tasks, such as blink,eye-movement,camera cut,mud splash,flicker, and other task of change detection of real-world.The research has primarily focused on the reason of change blindness, or the mechanism behind visual change detection, which has led to many important insights into visual perception, memory and awareness. Most results clearly indicate that more detailed visual information can be accumulated in memory. But whether the degree of information integration in flicker paradigms influence change detection is uncertain.Based on the problems, this paper adopted pictures of natural scene as stimulus material explored the effect of information accumulates on change detection using a flicker design and 108 sthudents from Heibei University take part in the experiments.In experiments,the number of repetitions of these pictures pairs was manipulated which were identical, or different in one single detail. The study used a mixed-design with type of change (color details, location of an object, or presence of an object.) as a within-subjects factor and group (presentation mode of the pictures) as a between-subjects factor.The results revealed that visual informations accumulated facilitate change detection and it is important to detect change to developing representation of both picture versions.Presence changes are easiest to detect, followed by changes in spatial locations and changes in color. The interaction between the factors change presentation mode and change type is not significant.
