The aim in the present study is to detect phase locking inherent in the tasks forcing abductive inference, which is a candidate of the index for logical thinking as a learning outocomes in CSCL(Comuper Supported Collaborative Learning). We detected the emergence of intermittent 1:5 phase locking between theta and delta oscillation in human scalp EEG in both an abductive inference task and a memory task by use of a wavelet transformation. However, the difference of the duration of the phase locking emergence could not be detected between the two tasks. Further design of abductive inference tasks forcing intensive logical thinking is remaining.

本研究的目的是检测强制溯因推理任务中固有的相位锁定，溯因推理是CSCL（计算机支持的协同学习）中逻辑思维作为学习成果的候选指标。我们利用小波变换检测了外展推理任务和记忆任务中人类头皮脑电图中θ波和δ波振荡之间出现的间歇性1:5锁相现象。然而，在两个任务之间无法检测到锁相出现持续时间的差异。进一步设计的溯因推理任务，迫使密集的逻辑思维仍然存在。
