目的：本篇研究的目的在於檢驗動作相關電位中的P300與手指輕敲測驗(Finger Tapping Test, FTT)兩者在健康男性受試者身上的關係。方法：幫三十位健康男性受試者進行腦波紀錄，讓受試者接受標準聽覺畸變試驗(auditory oddball task)，以獲得受試者之P300的資料。並讓受試者進行手指輕敲測驗。結果：P300的潛時與手指輕敲測的分數呈現顯著的負相關。結論：P300的潛時與手指輕敲測的分數之間顯著的負相關間接支持了多巴胺系統與P300的關係。

Objectives: The aim of this study was to examine the relation between the P300 event-related potential and the finger tapping test (FTT) scores in healthy male volunteers. Methods: The electroencephalograms (EEG) of 30 male subjects were obtained while they performed the oddball paradigm and the FTT. Results: The P300 latencies were correlated negatively with the FTT scores. Conclusion: The significant correlation between the FTT scores and the P300 latencies lends support to the theory that dopaminergic activity may be mediated in P300 generation.
