Experimental Study On Contextual Cueing Effect Based On Chinese Characters Material

Contextual cueing effect refers to repeated scenes or stimulus picture contains lots of location information, relationship information, the time sequence information, we can use these information as cues to guide us find target more quickly. It is a visual perception hot research field, has very important significance for the research scene perception.This paper describes the effect's theory origin, definition, classification, researc h methods and experimental logic in details. Then analyzed its essence and content of learning, the characteristics of the learning process on basis of these theory. The research designed three experiments in total and the first experiment is a comprehensive experiment, under the condition of visual search task paradigm, respectively investigates the background capacity, space layout, background significance on spatial contextual cuing effect in Chinese characters. At the same time, fitting the function relationship between background capacity and reaction time, by analyzing the characteristic of the slope and intercept of function graph to determine the processing characteristics of contextual cuing effect. the results shows that it appears spatial contextual cuing effect in C hinese characters pictures, processing of contextual cuing effect does not contain to semantic processing of Chinese characters, the promotion mainly due to the role of guiding attention, also thanks to the faster perceptual discrimination process. Experiment 2 and experiment 3 was conducted under the change detection task paradigm in Chinese characters material, the same spatial contextual cuing effect was found, experiment 3 change stimulus spatial layout but maintain fixed company condition found that there are obvious differences, it suggests that appeared object contextual cuing effect. Three experiment results show that(1) spatial contextual cuing effect, object contextual cuing effect won't be as experiment material, experiment task changes. 2. The machining process of contextual cuing effect is a double adjustment process, can guide the attention, and to speed up the Stimulus items confirmation. 3. In contextual cuing effect the visual information processing is superior to the processing of semantic information. 4. Participants can flexible use spatial layout, the subject-object relationship and other information to speed up the confirmation to the target.
