  • 為了探討專精者及生手對於作答物理試題的差異性,找了兩類族群進行物理試題實驗,相互比較。
    本研究使用全腦式306 陣列感測器腦磁圖儀系統及搭配眼動儀系統紀錄受試者在進行物理試題實驗時的腦磁訊號反應及眼部觀看題目時的歷程軌跡。由受試者作答物理試題實驗時,觀察專精者及生手觀看題目時及答題時腦區活化差異。本研究將同題型之物理試題實驗進行探討及深入研究,又將題目分割成QU前、QU後,QU前即代表受試者看到題目問題重點前的時間,QU後則代表看到題目問題重點後(包含QU)的時間。在實驗進行時,同時也記錄了受試者的眼動軌跡、作答紀錄、作答時間、眼動訊號、心跳訊號,以及腦磁信號,並在實驗結束後訪問受試者作答歷程。
    實驗發現專家及生手於實驗QU前後在特定活化腦區強度有所不同,而在計算大腦活化源連接性也發現,專家與生手在活化源連通區域也有所不同。

    In order to explore the differences between the experts and the layman in answering the physical questions, two groups of people were asked to conduct physical test experiments and compare them with each other.

    This research, We used a whole head sensor array (306 channels) magnetoencephalograph and the eye tracker system were used to record the brain trajectory response of the subject during the physical test experiment and the trajectory of the eye when reading exams. When the subject answers the physics test, observe the differences in brain activation between the experts and the layman when reading exams and answering the question. This research will discuss and in-depth study of the physical test of the same type of question, and divide the title into before QU and after QU. The QU represents the time before the subject sees the problem, and the QU represents the subjects. The time after the problem is focused (including QU). During the experiment, the subject's eye movement trajectory, answer record, answer time, eye movement signal, heartbeat signal, and brain magnetic signal were also recorded, and the subject was interviewed after the experiment.

    Experiments have found that experts and raw hands have different strengths in specific activated brain regions before and after the experiment QU. However, in calculating the connectivity of brain activation sources, it is also found that experts and raw hands are different in the activation source connectivity region.
