看你網絡頭像就能知道你的性格

Is your profile photo bright and cheery, or is it a brooding work of sociAl media art?
你的頭像照片明亮愉快嗎？抑或是社交媒體藝術孕育的成果？

According to a new study, these distinctions contain key clues about your Personality and can reveal whether you’re conscientious, extraverted, or even neurotic.
根據一項新研究，這些差別隱藏着關於你性格的關鍵線索，可以透露出你是盡責型，外向型，還是神經質的人。

Using thousands of Twitter profile pictures, an international team of researchers found that personality traits can be accurately predicted based on differences in aesthetic and facial presentation.
一個跨國研究團隊觀察了幾千張推特個人資料裏的頭像照片，發現基於美學和麪部展示方式的差異，可以準確推測性格特徵。

In a recent paper, Analyzing Personality through Social Media Profile Picture Choice, researchers analysed a data set of more than 66,000 Twitter users, and collected up to 3,200 of the most recent tweets for each person.
在最近發表的研究論文——《通過社交媒體頭像選擇分析用戶性格》中，研究者們分析了6.6萬推特用戶的數據，收集了每個用戶最近寫的3200條推特（如果有這麼多的話）。

Along with this, 434 Twitter users were given a psychological survey to determine their scores among the Big Five personality traits.
除此之外，434名推特用戶接受了心理測驗，根據結果來確定他們是五大人格特質中的哪一個。

These include extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience.
這些特質包括外向型、宜人型、盡責型、神經質型和開放型。

Profile pictures are likely an important indicator of personality, as they are chosen by the user to represent their online persona, the researchers explain.
研究人員解釋道，頭像照片很可能是人格的重要指標，因爲用戶選擇它們來代表自己在網上的形象。

So, they looked only at profile photos, and divided the features into two categories: general image features and stylistic facial features.
因此，他們只看頭像照片，並把照片特徵分爲兩類：一類是一般的圖像特徵，一類是充滿個人風格的臉部特徵。

The researchers analysed the differences in colour, composition, general type (meaning number of faces included), demographics, facial presentation, and expression.
研究人員分析了顏色、構圖、大體形式（就是照片上有多少張臉）、人口學特徵，臉部展示以及表情上的差異。

Then, they investigated the correlation between the personality analyses and the features of each image.
然後他們探究了人格分析和每張圖片的特徵之間的相關性。

Twitter users that have a profile picture with higher aesthetic quality – increased contrast, sharpness, saturation, less blur – were associated with open personalities, the team found.
研究團隊發現，頭像有更高審美價值的推特用戶——圖片對比度、清晰度、飽和度較高，模糊的較少，屬於開放型人格。

This group was also most likely to have a profile picture that contained something other than a face, indicating ‘non-conformance,’ they explain.
除了臉，這類人的頭像更有可能包含其它事物，暗示他們“不隨大流”，他們解釋道。

But, they were also less colourful, and the facial expressions were higher in negative emotion, particularly anger.
但是，他們的頭像沒那麼絢麗多彩，而且臉部表情表現出更多的消極情緒，尤其是憤怒。

As for conscientious users, the researchers found profile pictures were more colourful, natural, and bright.
至於盡責型的用戶，研究人員發現他們的頭像照片更絢麗多彩、自然、明亮。

These users were highly correlated with positive mood expressions, like smiling, and expressed the most emotions out of all the five traits.
這些用戶與積極表情高度相關，比如微笑，而且是五大人格中情感表達最豐富的一類人。

Extraverts were found to have the most colourful images, and tended to have profile pictures that contain multiple people.
研究發現，外向型的人頭像色彩最豐富，而且頭像照片上往往有好幾個人。

Users associated with agreeableness were also found to have colourful photos, which were blurry and bright.
宜人型的用戶頭像色彩也比較多，明亮但比較模糊。

Overall, these users express positive emotions.
總而言之，這些用戶表達的情感都比較積極。

Neurotic users, they found, tended to have simpler, uncolourful images.
他們發現，神經質型的用戶頭像往往更簡單，色彩更單調。

They were also more likely to opt not to present a face in their photos, and had an overall lack of positive emotions when a face was shown.
他們也更傾向於選擇沒有正臉的照片，即使有，臉上也全然沒有積極的表情。

Using this information, researchers say profile pictures can be harnessed to make predictions with ‘robust accuracy.’
研究人員表示，瞭解這些信息，就可以利用頭像對性格做出“靠譜的”預測。
