眼動儀實驗顯示:乳房之美,男女所見略同!

Breast Aesthetics and Symmetry
只要是宗教便會出現不同教派,歐派這門悠久的信仰當然也不例外,
究竟怎麼樣的歐派才是各教別間的公約數、可讓眾人皆稱之為”美”呢?
除了使用問卷或主觀量表調查之外,眼動儀(Eye-tracking)或許也能提供些不同面向的答案─
Gigazine看到的報導,波蘭研究生醫科教育中心(CMKP)整形外科的研究者Piotr Pietruski,
為了替進行乳房手術的患者找出一個較為客觀的美麗標準,使用眼動儀分析了100位受試者,
發現乳頭乳暈綜合區(NAC,nipple-areola complex)和下乳(IMF, inframammary fold)部份,
無論男女皆為最被吸引注意力的區域,是以想要尋找完美歐派…..先著眼這兩部份或許就對了!

…..Background: Because of its subjective character, the term “breast attractiveness” is poorly defined and thus its reliable standardized assessment can be particularly challenging. Because of objective analysis of the observer’s gaze pattern, eye-tracking technology may provide a better insight into the visual perception of breast aesthetics and symmetry…..
…..Methods: One hundred observers, 50 women and 50 men, assessed the aesthetics and symmetry of eight types of female breasts displayed as digital images on frontal, lateral, and oblique projections. The gaze pattern of each observer was recorded using eye-tracking technology, and gaze data were subsequently analyzed…..
…..Results: Although sex and breast type exerted an effect on attention capturing by some areas of interest, key characteristics of gaze patterns in female and male observers were essentially the same. Irrespective of observers’ sex, the longest fixation duration and the highest fixation number were recorded for lower breast regions, in particular, for the nipple-areola complex. Mean fixation duration in this area corresponded to 58 and 57 percent of overall observation time for female and male observers, respectively, during the assessment of breast aesthetics; and to 56 and 52 percent of overall observation time for female and male observers, respectively, during the assessment of breast symmetry…..
…..Conclusions: Nipple-areola complex and lower breast are key focus areas for the assessment of breast aesthetics and symmetry. Gaze data collected during this study may constitute a valuable source of reference values for future eye-tracking research on various patient groups’ visual perception of breast attractiveness and deformities…..

原研究論文: Analysis of the Visual Perception of Female Breast Aesthetics and Symmetry: An Eye-Tracking Study

這個實驗招募了非醫學領域的男女各50人,並分為兩個階段,
第一階段為美學上(Aesthetics)的評估,第二階段則為對稱性(Symmetry)的評估,
兩階段間相隔40分鐘,實驗素材為八種不同大小與下垂度乳房的三視圖(正面、側面與45度視角):
Analysis of the Visual Perception of Female Breast Aesthetic... : Plastic and Reconstructive Surgery
評分以1(Very poor)至10(Excellent)的李克特量表回答,受試者視線在實驗中全程以眼動儀紀錄,
Analysis of the Visual Perception of Female Breast Aesthetic... : Plastic and Reconstructive Surgery
收集的資料則依照實驗者事先劃分的不同乳房區域進行分析.

根據實驗數據,研究者發現受試者在進行美學評估時,無論性別,
觀看正面、側面與45度視角圖片的最初三個凝視點(fixations)大致重疊,
主要集中於乳頭乳暈綜合區和下乳部份,對稱性評估過程所得到的結果也十分類似;
令人意外的是,無論美學或對稱性評估,上乳房區域(upper regions)都沒有獲得明顯注視,
頸部、肩膀和鎖骨亦對視覺評估沒有什麼影響…..可見偏愛鎖骨與成為歐派星人並不衝突,
對那些追求”和服絕對領域“的紳士們來說真是個好消息呢! XD

文中也提到,即便實驗找到了可能是識別乳房吸引力的關鍵部位,
但對該些區域的評估視如何轉變為對美的認知仍無法回答,畢竟這牽涉主觀偏好,
過往研究甚至發現文化與社會經濟地位(socioeconomic status, SES)也會有所影響;
雖然目前的研界結果仍無從回答何為”美”的歐派,至少給了迷途之人一個可以鑽研的方向,
粧屍獸
是以若想強化歐派戰鬥力數值,比起漫無目的的盲目追求尺寸與形狀,
集中鑽研乳頭乳暈綜合區和下乳部份,或許會是個更加有效的策略呢!(咦)

歐派知識延伸閱讀:
只要按摩一萬次,歐派真的可能越揉越大!?
「覷乳之時,不見人,徒見乳耳」
專家表示:「貧乳就不要浪費布」
揉歐派,防乳癌!
With great breast, comes great…..lust?
坊やだからさ…..
因為只有「看」是不夠的!
咖啡果然是魔鬼的飲料!
這是成為おっぱい星人的基本入門
