& Fum, 2008），而本實驗在較晚的時間點(300ms-500ms)發現有 FRN，可佐證 此作業對受試者而言是較難理解的，因此本研究可能無法類推到所有情境。另外，
本實驗計算膚電反應的方式是用最多人使用的平均振幅，然而過去也有許多研究 使用不同計算膚電反應的方法（Miu, Heilman, & Houser, 2008；Oya et al., 2005），後續研究亦可探討不同計算膚電反應的方式是否會影響到結果。最後，
本實驗和過去許多研究一樣(Crone et al.,2004；Jenkinson et al.,2008)，是根據 受試者的行為表現加以分組，但也有許多研究利用人格問卷加以分組（Glicksohn
& Zilberman, 2010; Martin & Potts, 2009；Hooper, Luciana, Wahlstrom, Conklin,
& Yarger, 2008），後續研究亦可利用問卷來瞭解受試者的人格，來探討不同人格 傾向和風險偏好的關聯。

風險牌損失回饋膚電反應的差異，對風險偏好行為的影響較大，高風險酬賞引發 較大情緒和高風險損失引發較小情緒的受試者，接受高風險的牌的比率較高。
