汉语阈下语义启动无意识机制研究

Unconscious Mechanisms of Chinese Characters in Subliminal Semantic Activation

采用Klinger等人 (2 0 0 0 )的阈下语义启动研究范式 ,以汉字双字词为实验材料 ,用反应时和正确率为指标对阈下语义启动现象及其无意识机制进行了实验研究。结果发现 ,在与反应关系一致的维度上存在阈下语义启动现象 ;用反应时和正确率检测阈下语义启动时不存在敏感性差异。通过对阈下语义启动无意识机制及其相关研究的讨论 。

Following Klinger et al's(2000) paradigm, using Chinese characters as the experimental material and Reaction Time (RT) and Accuracy as a response criteria, this research was designed to study the mechanisms of unconscious processing and sensitivity difference between RT and Accuracy in Subliminal Semantic Activation. The results showed: (1) The SSA was observed in this experiment. It meant that unconsciousness was dissociated from consciousness in this experiment. (2) There was no sensitivity difference between RT and Accuracy on detecting SSA. Through a detailed discussion of the result of this experiment and the researches on unconscious mechanism,the authors hold that the present research results support the response competing model.
