摘要
已有研究发现,在回忆任务中问题解决可以诱发易化效应,但有关易化效应的研究并不是很多。实验1旨在探讨易化效应是否会在再认测试的背景中出现,以验证易化效应的稳定性;实验2通过高时间分辨率的事件相关电位技术来探讨易化效应的脑机制。研究选取中文远距离联想问题为材料,采用"学习——问题解决——再认"的范式进行探索。行为结果发现,固着反应词比基线反应词的再认成绩更好,这表明在再认任务中,问题解决也可以诱发易化效应,进一步验证了易化效应的稳定性。ERP的结果显示,固着条件和基线条件相比,N170成分的潜伏期缩短了,表明N170成分可能反映了知觉启动的过程。
Research has shown that problem solving can cause facilitation in recall task, however, there is few studies about it. In experiment 1, we examined whether an analogous phenomenon occurs in the context of recognition test to explore the stability of facilitation. Experiment 2 researched the brain mechanism of facilitation by the technology of ERPs. Using the RAT problems and the paradigm of ＂study--problem solving--recognition＂ to examine, we found that recognition performance in the fixation condition was better than in the baseline condition, suggesting that problem solving can cause facilitation in recall task. Result from ERP shown that the latency of N170 in the fixation condition has shorten relative to the baseline condition, suggesting that N170 may reflect the process of perceptual priming.
