為了對女性在生理期間的不適有更好的了解與改善，本研究以工作記憶測驗檢測女性生理痛對專注力的影響。
本研究利用128通道全腦式腦磁圖儀紀錄大腦在日常狀態與生理期間誘發的M170反應，藉由受試者在M170的出現時間與ECD強度中找出其疼痛程度與大腦活化的關聯性。共五位正常女性受測者參與，分別在非生理期間與生理期間進行工作記憶測驗。生理期間進行的實驗，須請受試者填寫疼痛量表，記錄疼痛的程度。依據疼痛程度的不同，分為疼痛指數為零的無痛組；以及大於零的疼痛組。過程中讓受試者記憶一組數字，後續顯示兩個數字作為題目，令受試者判斷是否與先前的數字之一吻合，同時記錄受試者反應時間、答題記錄，以及腦磁信號。
分析後發現在無痛族群中，非生理期間與生理期間的dipole強度呈現下降趨勢，而疼痛族群普遍上升。生理期間內，疼痛族群答題正確率普遍下降、需要更多的反應時間等，都證明女性的專注能力會在生理期間受到影響。

This research investigated the influence in attraction of female dysmenorrhea via working memory. We mainly used MEG to collected subjects’ brain activity data and behavior data during the experiment.
This study totally have five normal female subjects joined the experiment and used a whole head sensor array (128 channels) MEG to record the M-170 response during daily state and menstruation. While the female subject in her period. Operator would please subject to fill the pain intensity scales before her test. According to subjects’ pain scale, we classified them as two group: pain group and painless group.
The experiment designed as follow: First, subject will see a number set. Next, screen will display two numbers, then subject has to make a decision whether these two numbers as same as one of the previously number set or not. In this study, we recorded appearance time of M-170, dipole amplitude, response time and correct rate.
In comparison of dipole amplitude, the painless group almost reduced during menstruation.But the pain group generally rise,also, much more response time and reduction of correct rate all proved the influence in attraction of female dysmenorrhea.
