时序信息加工机制及其通道效应的实验研究

研究由两个实验组成，实验一采用纯粹的视听方式，以线段长度和声音频率为材料，对时序信息的加工方式（自动加工与控制加工）、编码特点（时序信息是何时编码的）以及通道效应进行了研究。实验二以汉字为材料重复实验一的过程；结果表明，时序信息的加工存在视听通道效应，其机制源于记忆，且与实验材料的加工深度以及加工方式有关；时序信息既包含有自动加工，又包含有控制加工。视觉刺激倾向于自动加工，而听觉则倾向于控制加工；时序信息是在项目学习时编码获得的，而不是在提取时建构的。

RESEARCH ON TEMPORAL SUCCESSION PROCESSING MECHANISM AND MODALITY EFFECTS

Two experiments were carried out in this research.The first experiment,by employing length of line and acoustic frequency studied three questions :how the temporal information is processed;when the temporal information is corded;and the temporal modality effects.The second experiment repeats the procedures of experiment one by utilizing new stimulus of Chinese words.The results showed that audio-visual modality effects exist in the processing of temporal succession information,and the mechanism of modality effects is rooted in memory and is related to the processing depth of material and way of processing.There are both automatic and controlled processing in processing succession information,the visual stimulation tends to process automatically,but acoustic stimulation processes in a controlled manner,The information of temporal succession is corded while the items are studied.
