摘要
本研究采用Oddball与Stroop相结合的范式,对导致Merikle与Daza等研究结果之间的矛盾进行了考察。研究发现,在启动刺激与目标刺激之间的SOA为300毫秒的即时掩蔽条件下,启动刺激"红"和"绿"对随后的目标刺激的判断产生了不同的影响,前者表现出典型的Stroop效应,后者表现出反转的Stroop效应;主观觉知阈限测验显示,启动刺激"红"是在阈下状态被知觉的,而启动刺激"绿"是在阈上状态被知觉的。结果表明,阈下知觉启动具有一定的时间延续性,并不局限在某一特定时间点上,启动刺激的知觉状态受多种因素影响。
This study explored the inconsistent findings from Merikle's and Daza's researches by combining the Oddball paradigm with the Stroop paradigm. The result showed that the primes 'red' or 'green' affected the judgment of the targets in a different way after the primes were masked immediately when the prime-target stimulus onset asynchrony (SOA) lasted 300 msec. The former displayed a typical Stroop effect, and the latter displayed a reversed Stroop effect. The subjective threshold test showed that the prime 'red' was processed subliminally, while the prime 'green' was processed supraliminally. This study indicated that perceptual priming could last a certain time course, and would not be limited to a certain time point, and the state of awareness to a prime was influenced by various factors.
