  1. 人帥真好--你的腦分得出誰比較帥嗎?-- 神經經濟學期末專題報告 2012 / 6 / 21 陳雪羚張雅雯黃晨軒 黃威銘黃飛揚 指導老師:黃貞穎 教授

  2. 報告大綱 • 實驗目的 • 實驗設計 • 統計方法 • 實驗結果 • 討論 • 改進方向 • 參考文獻

  3. 實驗目的 • 觀察辨認異性臉部吸引力(facial attractiveness)時的大腦神經表現,以及大腦活化強度與偏好和相對偏好差距的關係。

  4. 實驗設計 • 蒐集10張大學男生的照片,去除背景。

  5. 實驗設計

  6. (1) 單張試驗

  7. (2) 兩兩比較試驗

  8. 實驗結果-行為排序 5 1 2 4 3 7 16 14 11 18 8 10 8 5 7 7 6 5 5 1

  10. 你說蝦米 肖話!!!!!!!!!

  11. 吸引程度(次數)差與反應時間

  12. 為什麼有些圖要比較那麼久?

  13. 吸引程度(次數)差與反應時間

  14. 實驗結果-SPM圖 (1) 看臉/沒看臉看臉部有反應的腦區 • Fusiform Face Gyrus p=0.01 cluster=10

  15. p=0.01 cluster=10 • Fusiform Face gyrus

  16. (2) 與吸引力正相關的活化腦區Anterior Frontal Cortex (BA10) p=0.01 cluster = 10

  17. Orbital frontal cortexSuperior Parietal Cortex/ BA5

  18. (3) 與吸引力差距愈小正相關腦區Right BA 47 / DLPFC p=0.01cluster=10

  19. 討論 • 辨識臉部的腦區 • (2008) Facing facts neuronal mechanisms of face perception Monika Dekowska1, Michał Kuniecki2, and Piotr Jaśkowski3* -- One face-specific region is in thefusiformgyrusin both brain hemispheres -- Changeable elements were processed by a second face-specific processor superior temporal sulcus (STS) -- Show high activity when faces of famous or familiar persons are viewed the anterior part of the middle temporal gyrus (AMTG), the orbitofrontal cortex

  20. (2) 吸引力正相關腦區 • (2007) Brain systems for assessing facial attractiveness Joel S. Winston a,∗, John O’Doherty a, James M. Kilner a, David I. Perrett b, Raymond J. Dolan a -- Left posterior occipito-temporal cortex extending into lateral fusiform, and orbitofrontal cortex (OFC) -- Amygdala showed a significant non-linear response profile, with greatest responses to attractive and unattractive faces • (2008) Are attractive people rewarding? Sex differences in the neural substrates of facial attractiveness JasminCloutier, Todd F. Heatherton, Paul J. Whalen, and William M. Kelley -- Results revealed that the OFC preferentially responded to attractive faces, but only for male subjects

  21. (3) 比較兩男吸引力之困難度 • 新發現? -- DLPFC serves as the highest cortical area responsible for motor planning, organization, and regulation. -- The DLPFC may also be involved in the act of deception and lying, which is thought to inhibit normal propensity to truth telling.

  22. 反思與討論 • 帥是否可以定義為看到圖片時腦袋某區活化的程度? • 究竟是腦還是心在判斷誰比較帥?(困難抉擇時腦袋活化的區域在做些什麼)

  23. 你說蝦米 肖話!!!!!!!!!

  24. 改進方向 • 1. 照片標準化 • 2. 注意力對整體活化程度的影響 • 3. 應納入對臉部的直接評價   直接 v.s. 間接   活化程度是否不同?

  25. 參考文獻
