| Research Abstract |
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.
