摘要: 通过两个行为实验 ,采用句子核证作业 ,将SAD技术和普通反应时实验有机地结合起来 ,对语义信息加工的性质进行了详细的考察。实验一采用普通反应时实验 ,探讨了语义信息加工机制的性质 ,结果表明 ,在熟悉度、语义距离和快慢反应时之间存在复杂的交互作用 ,说明在语义信息加工中存在两种不同性质的加工机制 ,熟悉性是影响这两种不同性质加工机制的因素。实验二采用SAD技术 ,研究熟悉性对语义信息加工性质的影响。结果表明 ,在高熟悉句中的部分信息积累具有离散的趋势 ;而低熟悉句中的部分信息积累则是连续的 ,进一步证明了两种性质加工机制的存在。结论认为 :语义信息加工中存在着两种性质的加工 :离散性加工机制和连续性加工机制 ,熟悉性是影响二者关系的一个重要因素。

Abstract: The present study focused on the dynamics of semantic information processing, and the role of familiarity. In order to solve this problem, two experiments with speed-accuracy decomposition and conventional reaction-time paradigm were conducted to inspect how dose familiarity influence the dynamic of semantic processing. Experiment 1 used conventional reaction-time paradigm with sentence verification task to investigate the effects of familiarity and semantic hierarchical distance on time course of semantic process. The results showed there are complex interaction among familiarity, semantic hierarchical distance and percentile of reaction time. It provides evidences consistent with the dual-process mechanism in semantic processing. This mechanism combined discrete search and continuous computation. Experiment 2 used SAD technique with the sentence verification task. The aim of experiment 2 was to explore the familiarity effect on the available partial information accumulations of discrete search and continuous computation mechanisms. The results showed that the high familiarity sentences verification process produced discrete intermediate outputs of partial information; and the process of low familiarity produced continuous intermediate outputs of partial information.
