For researching the influence of the factors to contextual cueing effect, the author used the change detection task paradigm, and chosed 210 college students to participate the experiments, executed 2 studies and 7 experiments in the present paper. The first study mainly explored the overall features' change of the context information under the change detection task how to impact contextual cueing effect. There were 3 experiments in this study, to separately explored the influence of the context information presentation mode, the stimuli numbers in the context information and the presentation time of context information to contextual cueing effect under the change detection task. The second study mainly explored the concrete features' change of the stimuli in context information under the change detection task how to impact contextual cueing effect. There were 4 experiments in this study, to explored the influnce of the shape change of the stimuli, the color change of stimuli, the size change of stimuli in context information, and the distance change between the target probe stimulus and the filler stimulus to contextual cueing effect under the change detection task.The results of this study were as follows: (1) Under the change detection task, the overall features' change of the context information impacted contextual cueing effect significantly. Concretely, contextual cueing effect under the separate representaion mode was more significant than contextual cueing effect under the concentrated representation mode; Less stimuli in context information, contextual cueing effect was more significant; Long representation time, contextual cueing effect was more significant. That the overall features' change of the context information could affect contextual cueing effect, sustained the encoding specificity principle. (2) Under the change detection task, the concrete features' change of the stimuli in context information impacted contextual cueing effect significantly. Concretely, when there was no change in context information, contextual cueing effect was most significant;About the features of stimuli's shape, when the shape of the target probe stimulus and the filler stimulus changed at one time, contextual cueing effect was most nonsignificant;About the features of stimuli's color, when the shape of the stimuli in the memory image and the probe image was distinct,but the stimuli's color were on the same location in the two images, contextual cueing effect was most non significant;About the features of stimuli's size, when the size of the target probe stimulus or the filler stimulus changed , contextual cueing effect was most nonsignificant. These concrete features' change of the stimuli in the context information sustained the encoding specificity principle too. So, we can regard the encoding specificity principle as the theory interpretentaion of contextual cueing effect. (3) When compare the main results under the two tasks, the influnce of the stimuli's number to contextual cueing effect is main. Under the visual search task, the change of the stimuli's shape , color and size impacted the appearance of contextual cueing effect;But under the change detection task, the change of the stimuli's shape, color and size in the context information would not impact the appearance of contextual cueing effect, but they would impact the performance of the subjects,. So, we can say these can impact the contexual cueing effect.
