| 摘 要： | 通过微认知加工研究方法，探究了视觉感觉记忆的信息加工过程及其与TCE效应和Broca-Sulzer效应的相关性．实验证明：对于相继呈现在相同空间位置上的信号，视觉感觉记忆并非只是登记，还要对它们进行亮度上的叠加、衰减加工；TCE效应和Broca-Sulzer效应都是这种加工的结果．因此，TCE效虚和Broca-Sulzer效应足机制相同的同一的效应．

| Abstract: | To investigate the information processing in visual sensory.memory, and the rehttion between TCE and Broca-Sulzer effects, a miero-cognitive-proeess method was adopted in this paper. The experimental results revealed that the visual sensory memory not only registered stimulus, which were presented in rapid succession, but also summated and weakened the brightness information of sensory representations of these stimuli. TCE and Broea-Sulzer effects are both the consequence of this processing, thereby they are identical effects that share a common underlying mechanism. |
