问题解决诱发的易化效应及其脑机制研究

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
