Visual Presentation In Implicit Change Detection

Many studies have confirmed that even the object or event in field of view cannot be awared of, it affect one’s behavior in the next step. Implicit change detection is that the changes which are not realized affect the subsequent judgment behaviors. In this study, we used the implicit change detection paradigm from Fernandez-Duque and Thornton(2000). Three experiment has been designed to demonstrate (a) the visual presentation in preattention stage,(b) the influence of video game experience in presentation and attention,(c) the interference of distraction to the target task.In Experiment1, the color and shape were examined respectively in different visual field. In Experiment2, the characteristics of two dimensions are bound. Finally, distraction is added to the task in Experiment3. The results show (1) the change of color is more likely to be detected implicitly than the change of shape and change in central view is easier detected than ones in peripheral,(2) color still has advantages after binding two dimension of features,(3) distractions decline the task performance,(4) video game experience increases ones’ accuracy of implicit change detection in all experiments.The study conclutions are (1) visual representation of features is separated in preattention stage, and color is much more significant in this condition;(2) video game experience make the visual representation richer in the larger field of vision, which make better guidance to the subsequent change judgment;(3) color distractions disturb the task, but video game experience make one better to reduce the interference of task irrelevant factors.
