记忆源检测的双加工机制研究

本研究借鉴Mitchell等人的图词归源和早晚归源任务,引发启发式和系统式加工,并引入知觉流畅性变量,试图在知觉层面上分离两种加工的底层工作模式。结果发现:(1)源检测具有相对脆弱性,成绩显著差于再认。(2)启发式加工和系统式加工在加工速度和底层工作模式上分离,启发式加工速度快,其工作模式似乎是对刺激的知觉流畅性进行阈下水平的解释与归因,而系统式加工速度慢,其工作模式似乎是对意义的分析与推理。

The Dual-Process Mechanism of Source Monitoring

This experiment intended to reveal different underlying function rules of heuristic and systematic processing by using the word-picture source attribution tasks and early-late source attribution tasks to evoke heuristic and systematic processing separately and using perceptual fluency to dissociate two different kinds of processing.The results are: firstly,compared to recognition,source monitoring is relatively fragile,since the accuracy of source monitoring is significantly lower than that of recognition.Secondly,the results show a dissociation between heuristic and systematic processing in terms of speed and functioning modes.Heuristic processing is relatively fast and takes charge of the explation and attributon perceptual fluency below threshold,whereas systematic processing is slower and responsible for semantic comprehension and reasoning.
