摘　　要：本研究以汉语双字名词为材料、正确率和反应时为指标,进行了阈下启动的实验探索。揭示出(1)当启动词在前面的练习中被归类时,阈下语义启动显著表现出来,在练习中形成的阈下启动联接是词汇和语义范畴之间的;(2)练习中被归类的词在后续的不同按键反应任务中作为阈下启动词均发生作用,阈下启动是启动的无意识归类,而不仅仅是自动化的刺激-反应模式。Using Chinese characters as the sxperlmental material and Reaction Time and Accurasy as a response criteria, this research of priming effect indicated that ： （ 1 ） semantic priming occurs robustly when the words appearing as masked primes have been classified earlier in practice as visible targets. The experiment demonstrates that the associations formed in practice that underlie subliminal priming are between words and semantic categories. （2）Visibal words classified in practice functioned later as subliminal primes in different keypressing. This result shows that subliminal priming involves unconscious categorization of the prime, rather than just the aytomatic activation of a practiced stimulus-response mapping.
