摘要:
 采用启动-匹配范式,以包含时空因素或空间因素的表征图形为自变量,探索动态离散刺激的知觉组织中时间和空间因素的共同作用。结果:(1)动态离散刺激的一般编码特征为时空协同编码,即时间和空间因素二者协同编码,而非独立编码;(2)刺激间形成的主观轮廓会导致时空编码的协同作用解离,突出空间编码而削弱时间编码。结论:动态离散刺激的一般编码特征为时空协同编码,这一特征会因刺激间主观轮廓的存在而发生解离。
Abstract:
 The prime-response paradigm was used to explore the spatiotemporal coding principle of perceptual organization process of dynamic discrete stimuli,and investigate the influence of subjective contour on the general coding principle of dynamic discrete stimuli,using representational graphs containing spatial and temporal factors as independent variables.Firstly,in Experiment 1 and Experiment 2,we have found that the dynamic presentation of stimuli initiates the synergistic coding of spatiotemporal information,confirming the hypothesis that the coding principle of dynamic discrete stimuli are spatiotemporal synergistic coding,and the rapid response to spatial representation graphics is not affected by the speed of the stimuli.Secondly,Experiment 2 further explored the synergistic separation effect of subjective contour significance.Under the condition of big stimuli,subjective contour feature was obvious,spatial-coding was dominated,and it can be seen that the existence of the subjective contour can lead to more separation of the effect of spatiotemporal synergistic coding.The results of this study suggested that the general coding principle of dynamic discrete stimuli is spatiotemporal synergistic coding.When the subjective contour was formed between multiple stimuli,the spatial-coding will be highlighted and the temporal-coding will be weakened,resulting in the synergistic separation of spatiotemporal synergistic coding.
