对分心物特性抑制中位置因素的排除

本研究以汉语单字词为材料，使用反应时技术，考察在归类住条中分心物的位置因素是否也与分心物特性因素一样，影响被试对探测显示中目标的反应时间（RTDT）。结果表明，RTDT不随分心物位置数目变化而变化，只随着分心物特性数目变化而变化．由此得出，象归类这种属于语义表征的、与位置无关的任务中被试并不抑制分心物出现的位置，并可进一步推论，分心物抑制可能是一种灵活机制。

EXCLUDING THE LOCATION FACTOR IN DISTRACTOR IDENTITY INHIBITION

With Chinese single-character words as the ma-terial and reaction time as technique, this study exam-ined whether distractor location inhibition influencedthe reaction time on a target in a probe display (RT), as much as distractor identity inhibition did. The re-sults showed: RT varied not with the number of dis-tractor locations, but with the number of the distrac-tor identities. Therefore, we concluded that the sub-jects didn't inhibitate the location where the distractorappeared. In tasks such as categorization tasks, whichbelonged to the semantic representation and were notrelated to the location, the subjects didn't inhibit thelocations where the distractors appeared- Further-more, the distractor inhibition was probably a flexiblemechanism.
